trial and error test

The actual tests would employ the well-honed methods of operant conditioning, developed initially on pigeons, in which the test subject has first to work out what is going on by trial and error.

实际的测试会采用精确的操作性条件反射方法，测试对象首先要清楚实验的过程和错误。

Function test and adjust error for log on sea trial.

航行试验中计程仪效用试验及误差调整。

A plane strain test is then simulated by FEM, and the material's strain rate dependency is determined in a trial-and-error process so that the experimental and the predicted FLD0 correlate.

平面应变测试，然后通过有限元模拟，材料的应变率依赖性确定的试错过程，使实验和预测FLD0关联。
