Computational methods for structure prediction still have a way to go before they could replace experimental methods.

在他们找到其他试验方法之前，这种结构预测的计算方法还有很长的一段路要走。

The usual prediction methods of welding deformation include experimental method, analytical method, numerical method and equivalent load method, and the latter two methods are more commonly used.

焊接变形分析方法包括实验法、解析法、数值分析法、等效载荷法等，常用的是后两种方法。
