When I discovered this concept, after much difficulty andtrailanderror, I realized for the first time how huge it was. And how much people like you and me need to know about it.
The interaction parameters of surfactant have been processed by computer, and calculating flow has been designed for trailanderror method. Its application results are exact and efficient.
以计算机处理表面活性物质作用参数数据，针对试差法的特点，设计了计算流程。

Analogy method based on experience is insufficient for complex shape part andTrail-and-error. Only simple finite element increment simulation method is time consuming.
