说明：  该程序用于计算直齿轮时变啮合刚度，其原理基于势能法。(The program is used to calculate the time-varying meshing stiffness of spur gears. Its principle is based on the potential energy method.)

说明：  ballstic analysis of firing table data

说明：  Dobson模型作为一个函数，输入参数为：频率，温度，体积含水量，砂粒含量，粘粒含量，容重。 每个参数都只能是标量，不能是矩阵。 输入说明： 频率：单位是GHz 温度：单位是℃ 体积含水量：单位是cm3/cm3，范围是0~1 砂粒含量，粘粒含量：范围是0~100(Dobson model as a function, the input parameters are: frequency, temperature, volume water content, sand content, clay content, bulk density. Each parameter can only be scalar, not matrix.)
