-The script above (``send_request.sh``) sends a continuous stream of HTTP requests to Envoy, which in turn forwards the requests to the backend container. Fauilt injection is configured in Envoy but turned off (i.e. affects 0% of requests). Consequently, you should see a continuous sequence of HTTP 200 response codes.
+上面的脚本（``send_request.sh``）向 Envoy 发送连续的 HTTP 请求，随后，请求会被转发到后端容器。在 Envoy 中配置了故障注入，但是处于关闭状态（也就是说，请求不受任何影响）。因此，你应该看到连续的 HTTP 200 返回码。
