例句與造句

1. in this work, we detailedly introduced the whole ideas of rkdg finite element method and the theory of constructing gas-kinetic schemes based on boltzmann equation . and then presented a kind of new computational method for solving id and 2d compressible euler equations, i . e . firstly, we discretize euler equations in the space with discontinuous galerkin finite element method; secondly, we discretize temporal variable t with runge-kutta formula; thirdly, for numerical fluxes constructing, we give two kinds of different numerical fluxes-kfvs and bgk numerical fluxes by using gas-kinetic schemes
   本文分別對rkdg有限元方法的整個思想和基于boltzmann方程的分子動力學(xué)格式的構(gòu)造思想給予了詳細(xì)的介紹，并分別結(jié)合rkdg有限元方法與kfvs數(shù)值通量和bgk數(shù)值通量的構(gòu)造方法，給出了一種求解一維、二維可壓縮流體力學(xué)方程組新的計算方法，即，我們先用間斷有限元方法進(jìn)行空間離散，然后再對所得到的半離散格式使用runge-kuttatvd方法進(jìn)行時間離散，得到全離散格式。
2. It's difficult to find compressible euler equation in a sentence. 用compressible euler equation造句挺難的
