In order to accurately calculate casting temperature field, a method of simple variabletimestep is established which can ensure the precision of casting temperature field and the speed of calculate.
本文中提出了一种较简便确定变时间步长的方法，该方法可以确保温度场的计算精度和计算速度。

The value to the variable can be passed from another operator (as is shown in the next step) or even from the mashup URL at run time.
变量的值可以在运行时从另一个操作符(如下一步所示)甚至mashup URL传递。

To overcome the long test time and big error in single variable open loop step test method, a novel identification method based on asymptotic theory (asym) is presented.
