Using the method we calculate the 〓 elasticdifferential scattering cross section, excitation differential scattering crosssection, and excitation cross section of electron collision with 〓 We transform the electron and molecule problem into electron problemby Born-Oppenheimer approximate. Mr Rossi, Dr. the Flinders University ofSouth Australia, calculated electron collision with molecule, but theexchange term he used become bigger and bigger as incident energyincreases, it is unreasonable, besides, the potential of electron and nucleus heused is somewhat rough. At present we correct these two terms. The potentialconsists of static potential, exchange potential, polarization potential.

电子与分子的碰撞过程的相互作用势主要是由静态势、交换势和极化势三部分决定的，这里对这三部分在动量空间中进行分波展开，推导出易于计算的表达形式，根据这些公式，并参考Rossi的弹性碰撞程序编写了计算电子与分子碰撞激发截面的程序，利用程序计算出势能矩阵元，通过求解Lippmann-Schwinger方程求得T矩阵元，便可求得散射截面。

Do not cross and double-cross the answers, your doubts are caused by pressure, develop confidence in what you say.

不要跨和双跨的答案，您怀疑所造成的压力，发展的信心，你说的话。

Double-cross 例句: Don't double-cross your friend.

误译： 不要在你的朋友面前画两个十字。

If the turnout will be double-cross the X-shaped above two points and two points respectively below link, that is, cross-crossing lines.

如果将复式交分道岔的X形的上面两点和下面两点分别连接起来，就是交叉渡线。

The results indicate that integration of the operon by a single-cross or double-cross event causes an increase of 14%~19% or 40%~44% in riboflavin production, respectively.

结果表明，核黄素操纵子通过单交换重组方式整合在上述位点可使核黄素合成量增加14%~19%，而通过双交换重组方式整合在amyE或thrC位点可使核黄素合成量增加40%~44%。

The flow regime in downcomer can be divided into two kinds: cross flow injection and impingement. Cross flow injection only takes place under low injection flow rate in dowcomer flow. The investigation on flow regime and heat transfer in RPV under PTS is for the first time in China.

在国内本实验是第一个研究下降环腔内的流动与传热，在国际上，象这样同时进行了流动可视化，常温常压下传热和高温高压下传热的实验也不多，特别是针对下降环腔内对流换热系数的研究，在公开文献中还没有相类似的实验。

妈妈那么高兴以至于坚持自己过吊桥，我们能看到好多年轻人过桥害怕的样子，妈妈很轻松地就走过去了。

And those collision cross sections may be determined by fitting the simulation results from experiment data. At first, we calculate the effective ionization coefficients/N and drift velocity Ve of pure gas to determine collision cross sections in this paper, and the calculated results are agreement with the experiment data.

本文首先建立单一气体电子崩发展的蒙特卡罗模拟方法，用得出的电子崩参数与实验结果比较的方法，计算单一气体的/N和漂移速度Ve，并与实验数据比较，以确定碰撞截面的准确性。
