在双方可以在他们的集成中间件或者是系统接口上进行任何所需的改变之前，他们也应首选涵盖来自双方的需求协议。

They also primarily cover issues that require agreement from both parties before either side can proceed with any changes needed within their integration middleware or system interface.

这些中间件功能的提供应以一个重要的原则为基础：服务和流程开发人员应远离中间件实现的复杂细节。

One important principle should underlie the provision of these middleware capabilities: service and process developers should be insulated from the complexities of the middleware implementation.

如果焊接工艺试验在高热输入值和低热输入值下进行，那么，中间的热输入也应合格。

If welding procedure tests have been performed at both a high and a low heat input level, then all intermediate heat inputs are also qualified.
