正如每个整数都可用一些质数的积表示，任一对象的对称都可由所谓简单群的基本构件集合构造出来。

Much as every integer can be broken down into a product of prime Numbers, the symmetries of any object can be constructed from a collection of basic building blocks known as simple groups.

其次，在数值求解该组方程的过程中，未知函数裂纹表面位移差被近似为位移差的基本密度函数与多项式之积。

Then these equations are solved numerically by approximating the unknown displacement difference to a product of the fundamental density function and polynomials.
