pre-production welding test 预生产焊接试验
Most organizations have more than one run time environment, including development test, system test, performance, and pre-production.
大多数组织拥有一套以上的运行时环境，包括开发测试、系统测试、性能和预生产。
As the system test, performance test and pre-production environments are used for testing, there is a set of tools that no ideal environment should be without.
由于系统测试环境、性能测试环境和预生产环境用于测试，所以有一组工具是理想的环境不可或缺的。
For example, the administration staff may use this environment to test new patches and configuration changes before they are rolled into the pre-production and production environments.
例如，管理人员可以在新的补丁程序和配置更改并入预生产和生产环境之前使用这种环境对它们进行测试。
