不可缺少的

In this paper the software using the method of integral equation to calculate 3D magnetic field and another two programs which use the finite column method to calculate 3D heat field with phase transition and 2D gas-flow field are completed. These programs provide such technique as the access to large quantity data and a simple but effective method to eliminate hidden lines of objects, which are necessary for the calculating of 3D field.
