无et al时，可否将姓名与年份最后一个逗号改为“&”或“和”，其余情况保持默认设置。

您好，
关于文献引用的显示，默认的设置确实非常好。但是在默认的情况下，第一作者不足以区分文献，靠考虑第二作者，这挺好。只是如果只有两位作者，那么中间的逗号是不是应该改为 & 或 和. 比如

您好，
应该是在没有 et al的情况下，最后两位作者的姓之间的逗号应该变成 & 或 和。同时年份也可以这样。所以是这个形式：

(Phillips, 2001 & 2002; Phillips & Gregg, 2001; Phillips & Koch, 2002)

年份有这样的形式吗？姓名这种形式我是见过的。

  abstract = {An abnormally high concentration of organic matter (OM) in Lake Hulun, a large shallow eutrophic lake located in the sparsely populated Hulun Buir Steppe, was observed in a field investigation. Little was known about the origin of the OM. To identify the source of the OM in Lake Hulun, the carbon/nitrogen (C/N) ratio, natural abundance of stable isotope and three dimensional excitation emission matrix (3DEEM) fluorescence spectroscopy techniques were employed. Furthermore, a cyanobacterial incubation and degradation experiment was conducted in the laboratory to quantify the contribution of algae to dissolved organic matter (DOM) in Lake Hulun. C/N, the stable carbon isotope (δ13C) values typical of C3 plant debris in particulate organic matter (POM) and the fluorescence indices of DOM indicate that most of the OM in Lake Hulun is of terrigenous origin. It was deduced that only about 10.2\% and 7.3\% of DOM were contributed by algae in September and January, respectively, according to the linear correlation between the concentrations of algae-derived DOM and the fluorescence intensities of tyrosine-like matter. According to the stockbreeding development and climate change in Hunlun Buir Steppe, we deduced that the destruction of the grassland ecosystem by overgrazing in specific locations and trends in climatic warming and drying were the main factors causing the increase of OM and nutrient concentrations in Lake Hulun. This result highlights the need to pay more attention to the inputs of terrigenous organic matter to the lakes in northern China.},

  abstract = {This paper is a brief review on nutrient variation (changes in element concentrations and ratios) and the associated aquatic ecosystem responses in the subtropical region. Human activities have significantly modified both the flux and the ratio of nutrients delivered to aquatic ecosystems. Climate perturbations influence the hydrological regime and enhance nutrient mineralization and transport from land to receiving waters. Changes in land use and damming have resulted in changes in the balance among nitrogen, phosphorus and silicon elements, thus increasing the risk of algal bloom. Nutrient variation and its ecological effects in the subtropical region could be more significant than in other areas because of rapid development and high population. Aquatic ecosystems respond to nutrient variation in complex and dynamic ways resulting in eutrophication, hypoxia/anoxia, acidification, and changes in phytoplankton and microbial communities. This review suggests that harmful algal bloom, jellyfish bloom, and serious pathogens are often associated with nutrient variations. The current challenges to scientific research and management include the facts that (1) the link between nutrient dynamics and ecosystem responses is poorly understood; (2) monitoring data to support modeling and management are scarce; (3) aquatic ecosystems are site-specific and/or situation-specific and are highly dynamic, giving greater complexity in research and management; and (4) the lack of regional coordination in traditional management causes transboundary gaps. To address these current challenges, an integrated management framework was proposed for effective nutrient management. Institutional arrangements should be developed to coordinate across multiple government agencies and other stakeholders from watershed to coast. The framework should integrate an interdisciplinary scientific approach and adaptive principles regarding nutrient management.},

A total of 86 groundwater samples were collected from private wells in rural areas where the groundwater is the main source of drinking water. Statistical analysis indicates that the concentrations of NO3–N in groundwater range from 0.49 to 62.20~mg/L with a mean of 12.15~±~12.92~mg/L. 40.7~\% of groundwater samples are unfit for drinking purpose because of high nitrate concentrations that have exceeded the permissible limits recommended by the WHO and Chinese drinking water standards. Elevated NO3–N levels found in the study area may be attributed to the increased fertilizer rate, intensive irrigation, shallow groundwater depth, high permeability of soil, poor sanitation facilities, and bare infrastructures. Furthermore, non-carcinogenic risk of nitrate incurred by drinking contaminated groundwater in the area was estimated by using the USEPA human health risk assessment method. Only eight and four samples with high nitrate concentrations belong to the domains of the hazard index~{$>$}1 for infants and adults, respectively, indicating the higher health risk in these sampling sites. This study will be useful to develop effective strategies for improving rural drinking water supply and provide scientific evidence for decision and management of the groundwater.},

We found that seagrass meadows adjacent to mangroves had significantly higher soil OC concentrations, soil OC with lower δ 13C, and lower bulk density than those at the non-mangrove adjacent meadows. Soil OC storage to 30\,cm depth ranged from 3.21 to 6.82\,kg\,C m−2, and was also significantly higher at the mangrove adjacent meadows than those non-adjacent meadows. δ13C analyses revealed that mangrove OC contributed 34 to 83\% to soil OC at the mangrove adjacent meadows. The δ13C value of seagrass plants was also different between the seagrasses adjacent to mangroves and those which were not, with lower values measured at the seagrasses adjacent to mangroves. Moreover, we found significant spatial variation in both soil OC concentration and storage, with values decreasing toward sea, and the contribution of mangrove-derived carbon also reduced with distance from the forest.},

In the present study, statistical and correlation analyses were carried out to assess nitrate and fluoride contamination in groundwater in Zhongning area, Northwest China, where rural residents totally depend on groundwater for drinking. The associated health risks for different age groups (infants, children, adult female, and male) were assessed based on the USEPA model. Results show that NO3–N and F− concentrations in groundwater are in the ranges of 2.66–103 and 0.11–6.33~mg/L, respectively. Of the 50 samples, 30 and four samples have high NO3–N and F− levels exceeding the acceptable limits for drinking purpose recommended by the WHO (10 and 1.5~mg/L), respectively. Enrichment of nitrate contamination is primarily due to the human activities, and dissolution of fluorite is the primary source of fluoride in the groundwater. Correlation values of NO3–N and F− with other chemicals have further confirmed the sources of contaminant in groundwater. Infants are the most vulnerable groups through ingestion pathway. As per the obtained hazard index, majority of the samples (72 and 60~\%) may pose adverse effects on infants and children, but the proportions are relatively lower for adult female and male (28 and 22~\%). These finding suggest that there is an instant need to take ameliorative steps in this region to prevent the residents from nitrate and fluoride exposure through ingestion.},

  abstract = {The Liao River Basin is one of seven primary river Basins in China. The concentration of dissolved inorganic N (DIN), dual isotopes of NO3- using the denitrifier method, the N isotopes of NH4+ and the N flux in the basin were determined to identify the sources of N and their transformation. The results show that NO3- ranges from 0.3μmol/L to 1316μmol/L. In general, NO3- is the dominant inorganic N species during both flow seasons, but the fraction of NO3-/DIN is variable and high NH4+ is present in some waters. Samples collected from the up-stream portion of the Liao River typically had N isotope values of {$<$}+8‰, while those from the middle and lower portions had values of {$>$}+8‰ during the high flow season. Most water samples had O isotope values of {$<$}+10‰ during the high flow season. During the low flow season, the ranges of N and O isotopic values were limited, with average values of +10.3‰ and +4.9‰, respectively. There is a wider isotopic range of NO3- during the high flow season than the low flow season. The isotopic pattern of NO3- suggests that wastewater and soil organic N are the sources of NO4+ during the high flow season, while wastewater is the main source during low flow season. It appears that no intense denitrification occurs in the river according to the isotopic and chemical data. The N flux of the Liao River system entering the Liao Dong Bay annually is nearly 7.0×104tons, which amounts to 5.0\% of the N from chemical fertilizers used in this basin.},

  abstract = {An abnormally high concentration of organic matter (OM) in Lake Hulun, a large shallow eutrophic lake located in the sparsely populated Hulun Buir Steppe, was observed in a field investigation. Little was known about the origin of the OM. To identify the source of the OM in Lake Hulun, the carbon/nitrogen (C/N) ratio, natural abundance of stable isotope and three dimensional excitation emission matrix (3DEEM) fluorescence spectroscopy techniques were employed. Furthermore, a cyanobacterial incubation and degradation experiment was conducted in the laboratory to quantify the contribution of algae to dissolved organic matter (DOM) in Lake Hulun. C/N, the stable carbon isotope (δ13C) values typical of C3 plant debris in particulate organic matter (POM) and the fluorescence indices of DOM indicate that most of the OM in Lake Hulun is of terrigenous origin. It was deduced that only about 10.2\% and 7.3\% of DOM were contributed by algae in September and January, respectively, according to the linear correlation between the concentrations of algae-derived DOM and the fluorescence intensities of tyrosine-like matter. According to the stockbreeding development and climate change in Hunlun Buir Steppe, we deduced that the destruction of the grassland ecosystem by overgrazing in specific locations and trends in climatic warming and drying were the main factors causing the increase of OM and nutrient concentrations in Lake Hulun. This result highlights the need to pay more attention to the inputs of terrigenous organic matter to the lakes in northern China.},

  abstract = {This paper is a brief review on nutrient variation (changes in element concentrations and ratios) and the associated aquatic ecosystem responses in the subtropical region. Human activities have significantly modified both the flux and the ratio of nutrients delivered to aquatic ecosystems. Climate perturbations influence the hydrological regime and enhance nutrient mineralization and transport from land to receiving waters. Changes in land use and damming have resulted in changes in the balance among nitrogen, phosphorus and silicon elements, thus increasing the risk of algal bloom. Nutrient variation and its ecological effects in the subtropical region could be more significant than in other areas because of rapid development and high population. Aquatic ecosystems respond to nutrient variation in complex and dynamic ways resulting in eutrophication, hypoxia/anoxia, acidification, and changes in phytoplankton and microbial communities. This review suggests that harmful algal bloom, jellyfish bloom, and serious pathogens are often associated with nutrient variations. The current challenges to scientific research and management include the facts that (1) the link between nutrient dynamics and ecosystem responses is poorly understood; (2) monitoring data to support modeling and management are scarce; (3) aquatic ecosystems are site-specific and/or situation-specific and are highly dynamic, giving greater complexity in research and management; and (4) the lack of regional coordination in traditional management causes transboundary gaps. To address these current challenges, an integrated management framework was proposed for effective nutrient management. Institutional arrangements should be developed to coordinate across multiple government agencies and other stakeholders from watershed to coast. The framework should integrate an interdisciplinary scientific approach and adaptive principles regarding nutrient management.},

A total of 86 groundwater samples were collected from private wells in rural areas where the groundwater is the main source of drinking water. Statistical analysis indicates that the concentrations of NO3–N in groundwater range from 0.49 to 62.20~mg/L with a mean of 12.15~±~12.92~mg/L. 40.7~\% of groundwater samples are unfit for drinking purpose because of high nitrate concentrations that have exceeded the permissible limits recommended by the WHO and Chinese drinking water standards. Elevated NO3–N levels found in the study area may be attributed to the increased fertilizer rate, intensive irrigation, shallow groundwater depth, high permeability of soil, poor sanitation facilities, and bare infrastructures. Furthermore, non-carcinogenic risk of nitrate incurred by drinking contaminated groundwater in the area was estimated by using the USEPA human health risk assessment method. Only eight and four samples with high nitrate concentrations belong to the domains of the hazard index~{$>$}1 for infants and adults, respectively, indicating the higher health risk in these sampling sites. This study will be useful to develop effective strategies for improving rural drinking water supply and provide scientific evidence for decision and management of the groundwater.},

We found that seagrass meadows adjacent to mangroves had significantly higher soil OC concentrations, soil OC with lower δ 13C, and lower bulk density than those at the non-mangrove adjacent meadows. Soil OC storage to 30\,cm depth ranged from 3.21 to 6.82\,kg\,C m−2, and was also significantly higher at the mangrove adjacent meadows than those non-adjacent meadows. δ13C analyses revealed that mangrove OC contributed 34 to 83\% to soil OC at the mangrove adjacent meadows. The δ13C value of seagrass plants was also different between the seagrasses adjacent to mangroves and those which were not, with lower values measured at the seagrasses adjacent to mangroves. Moreover, we found significant spatial variation in both soil OC concentration and storage, with values decreasing toward sea, and the contribution of mangrove-derived carbon also reduced with distance from the forest.},

In the present study, statistical and correlation analyses were carried out to assess nitrate and fluoride contamination in groundwater in Zhongning area, Northwest China, where rural residents totally depend on groundwater for drinking. The associated health risks for different age groups (infants, children, adult female, and male) were assessed based on the USEPA model. Results show that NO3–N and F− concentrations in groundwater are in the ranges of 2.66–103 and 0.11–6.33~mg/L, respectively. Of the 50 samples, 30 and four samples have high NO3–N and F− levels exceeding the acceptable limits for drinking purpose recommended by the WHO (10 and 1.5~mg/L), respectively. Enrichment of nitrate contamination is primarily due to the human activities, and dissolution of fluorite is the primary source of fluoride in the groundwater. Correlation values of NO3–N and F− with other chemicals have further confirmed the sources of contaminant in groundwater. Infants are the most vulnerable groups through ingestion pathway. As per the obtained hazard index, majority of the samples (72 and 60~\%) may pose adverse effects on infants and children, but the proportions are relatively lower for adult female and male (28 and 22~\%). These finding suggest that there is an instant need to take ameliorative steps in this region to prevent the residents from nitrate and fluoride exposure through ingestion.},

  abstract = {The Liao River Basin is one of seven primary river Basins in China. The concentration of dissolved inorganic N (DIN), dual isotopes of NO3- using the denitrifier method, the N isotopes of NH4+ and the N flux in the basin were determined to identify the sources of N and their transformation. The results show that NO3- ranges from 0.3μmol/L to 1316μmol/L. In general, NO3- is the dominant inorganic N species during both flow seasons, but the fraction of NO3-/DIN is variable and high NH4+ is present in some waters. Samples collected from the up-stream portion of the Liao River typically had N isotope values of {$<$}+8‰, while those from the middle and lower portions had values of {$>$}+8‰ during the high flow season. Most water samples had O isotope values of {$<$}+10‰ during the high flow season. During the low flow season, the ranges of N and O isotopic values were limited, with average values of +10.3‰ and +4.9‰, respectively. There is a wider isotopic range of NO3- during the high flow season than the low flow season. The isotopic pattern of NO3- suggests that wastewater and soil organic N are the sources of NO4+ during the high flow season, while wastewater is the main source during low flow season. It appears that no intense denitrification occurs in the river according to the isotopic and chemical data. The N flux of the Liao River system entering the Liao Dong Bay annually is nearly 7.0×104tons, which amounts to 5.0\% of the N from chemical fertilizers used in this basin.},

您好， 但是年份可以用 & 合并吗？ 比如

(Phillips, 2001 & 2002; Chen 2001, 2002 &2003)

在我见过的中西文体例中没有用“&”合并年份的。

[hushidong]

ok

[hushidong]

已修复， 8d1d108

修改这个间隔符 \compextradelim 可以自定义a和b之间的间隔符。
比如：

\renewcommand{\compextradelim}{\addcomma} %无空格
\renewcommand{\compextradelim}{\addcomma\addspace} %有空格

[earthmoon]

您好，
默认的并没有改对吧？除了\renewcommand我应该怎么更新您修复后的版本？
\renewcommand{\compextradelim}{\addcomma\addspace}加上去也没有用好像。是不是我要更新一下版本？
