nodal solution

基本解釋

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(tài)兩群多維中子擴(kuò)散方程的動(dòng)力學(xué)節(jié)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(duì)稱的，此外在增量求解過程中用節(jié)點(diǎn)變量的全量進(jìn)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(jié)面解和這次地震發(fā)生的構(gòu)造條件，并解釋了一些宏觀地震現(xiàn)象。
