不规则几何 meaning in Chinese

irregular geometry

4 due to the irregular geometric boundary and the complicated internal heat source distribution , the theoretical solution of transient temperature field for specimens with flaws is very difficult
4 、由于含缺陷的构件具有不规则几何形状，且具有复杂内热源，在进行温度场解析求解过程中遇到很大困难。
The numerical examples have shown that the parallel algorithm presented for contact - impact simulation on a pc cluster exhibits good parallel efficiency and scalability . a new modified greedy algorithm is presented in this paper which can obtain better length to width ratio through considering the information of nodes
提出了一种修正的greedy算法以完成区域自动划分的任务，相对于传统的greedy算法，新算法使得分割子域具有更好的长宽比，且适用于不规则几何形状的有限元网格的区域划分。
