物体姿态解算算法子程序，包涵了各种在姿态解算仿真是需要用到的子程序，(The object attitude solution to calculate another way the program encompasses a variety of attitude solution simulation is the need to use a subroutine,)

The plane stress analysis refers to the problems where the thickness of the structure is very small compared to other dimensions of the structure in the XY plane. The plane stress problem is a 2D problem. The stresses in the z direction are considered to be negligible,
 
0, the stress-strain compliance relationship for an isotropic material becomes,

该程序对于重力异常的数据可以进行导数换算，对于重力数据处理有很大的用处。(The procedure for the gravity anomaly data can be derivative conversion, is very useful for processing gravity data.)
