例句与用法

1. On the basis of experimental research , this thesis applies 2 - dimensional non - linear finite element method to the analysis of transient temperature field on the section by means of relatively high precision triangular element of six joints . when the temperature field is analyzed , finite element reseaus are divided in space field and finite difference reseaus are divided in time field , and then the program is compiled . the computing results are in good agreement with the test data
   在试验研究的基础上，本文采用精度较高的三角形六结点单元对构件截面二维非线性瞬态温度场进行了有限元分析，即在空间域内采用有限元网格划分，在时间域内采用有限差分网格划分，据此编制了计算程序，计算结果与试验数据符合较好，程序稳定性好，精度满足要求。
