求解雷诺方程有有限元法、有限差分法、有限体积法，本程序就是采用有限体积法对雷诺方程进行求解。(Solving Reynolds equation has finite element method, finite difference method, finite volume method, the program is the use of finite volume method to solve the Reynolds equation.)

弹性补偿法的程序，在abaqus中进行二次开发，可以计算各种结构的极限载荷。(The elastic compensation method of the procedure, carries on two times of developments in ABAQUS, can be used to calculate the limit load of various structures. )

RPCA的求解方法(利用拉格朗日乘子法，进行迭代)(the solution of RPCA called ALM)

抛物方程是由赫姆霍兹方程推导而来，在计算大区域电磁传播有较大的优势，本程序是二维的情况。(Parabolic equation is derived the Herm Holtz equation, in the calculation of large areas of electromagnetic propagation has a greater advantage, the program is a two-dimensional situation.)
