On the other hand, it is found that choosing the appropriate coordinate system can effectively reduce the integrationvariable dimension and finally arrive at the same result.
另一方面，发现可以通过选取合适的坐标系可有效地降低积分动量的维数，同样可以求得关联函数的解析式来。

The Systems Integration Test phase returns to the main use case and identifies the appropriate number of alternate and variable paths through the use case.
系统集成测试阶段回到主要用例，识别整个用例中交替可变路径的合适编码。

Well, I don't expect that you would need integration by parts, although I still hope that some of you remember it from single variable calculus.
