Warning signs - watch out for tests that change frequently, boomerangs, testslippage, just in case code and shotgun surgery.
频繁改动的测试、退回返工、测试延误、以防万一的代码以及霰弹式修改(即到处修改)。
2
The asymmetrical slippage grid technique, the numerical computation, the moving model test, and the full-scale train test for air pressure pulse from trains passing each other are introduced.
讨论了列车交会空气压力波数值计算方法、动模型及在线实车试验技术，论述了非对称滑移网格技术。
3
Spinning test proved that slippage rate of non treatment apron was smaller than that of treatment apron, and could improve spinning quality.
