threshold distance meaning in English

临界距离

In aim solver , the convergence rate depends on spectral properties of the aim matrix , and the near - zone threshold distance has a dramatic impact on the memory and cpu time . a poorly conditioned matrix occurs through aim when a smaller near - zone
另外,自适应积分方法计算中,在保证计算精度的条件下,较小的耦合距离将极大减小内存需求和计算的复杂度,但同时误差积累也导致矩阵的性态变坏。
It presents the angle of the two normal vectors formed by the new and the old triangles , the threshold distance and the principle of maximal - minimal angle in the paper to constrain the growing of the triangles , so as to reduce the searching area , improve the correctness and confirm the quality of the mesh
该方法通过引入三角形法向量夹角、阈值距离以及最小内角等几个参数对三角形的生长进行约束,同时利用生长法,对空间中的离散点集进行逐步三角划分,直至所有三角形扩展完毕。
