单元位移 meaning in English

element displacement

First of all , with thrice hermite interpolation to element displacement , the control equation of dynamics is derived in space - time domain . two groups of space - time finite element formulae solving displacement and velocity are obtained
作者首先对单元位移采用时域上三次hermite插值多项式，在空间域和时间域中联合离散控制方程，分别推导出了动力学问题的两组递推公式，以求解位移和速度。
