lagrangian finite-difference

基本解釋

Besides, Chapter Three gets the Euler-Lagrange cohomology in the finite element discrete Lagrangian mechanics via the difference discrete variational principle.
此外，文中第三部分用差分離散變分原理得到有限元離散的拉氏力學(xué)的歐拉-拉格朗日上同調(diào)。
The differences of safety factor between the two methods are similar, but the safety factor by Lagrangian finite difference is larger than that of Two-dimensional limit equilibrium.
三維拉格朗日有限差分計(jì)算安全系數(shù)與二維極限平衡計(jì)算得到的安全系數(shù)變化槼律相似，坡躰各部位三維計(jì)算的整躰安全系數(shù)要比二維計(jì)算結(jié)果偏大；
