number density of molecules 中文意思是什麼
number density of molecules
解釋
分子數密度-
The chemical reactions in the flame area are very complex. it is very difficult to measure the number density distribution of the particles ( atoms, ions and molecules ), so the relative intensity method is employed
由於固體推進劑燃燒區內發生的化學反應非常復雜,直接測量火焰區內的粒子(原子、離子以及分子等)數密度比較困難,因此選用相對強度法來進行計算。
