nodal solution

基本解释

A kinetics nodal method for the solution of transient two-group multi- dimensional neutron diffusion equation is described.
介紹一種求解瞬態兩群多維中子擴散方程的動力學節塊方法。
As a result, the element tangent stiffness matrix is symmetric and is updated by using the total values of the nodal variables in an incremental solution procedure.
因而，得到的單元切線剛度矩陣是對稱的，此外在增量求解過程中用節點變量的全量進行更新。
The authors also briefly discuss the nodal plane solution based on P waves and the tectonic conditions relating to the occurrence of the earthquake. Finally some macroseismic phenomena are explained.
作者還扼要地討論了P波節麪解和這次地震發生的搆造條件，竝解釋了一些宏觀地震現象。

變號解
In this paper, we study the existence and concentration behavior of a nodal solution to a kind of semilinear elliptic equation with Dirichlet boundary value by using minimax and truncation methods.
