The variety, production cross section, energy spectrum and double differential cross section have been calculated for the secondary particles produced by reactions of high energy protons in silicon.

计算得到了不同能量的高能质子与硅反应产生的次级粒子种类、截面、能谱和双微分截面。

The calculated double differential cross section of the new model is compared with experimental data and previous SCDW calculations with single particle model. The calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi-elastic scattering angle. The agreement with experimental data is much improved.

新模型的双微分截面计算结果与实验值以及以前采用单粒子壳层模型时的计算结果进行了比较，表明CDFM模型的引入对SCDW模型的计算结果有较大的改进，使其在大角度和极小角度区域有所增大，在准弹性散射角附近有所减小，从而能更好地与实验值相符合。

We fit the anisotropic interaction potential based on the Murrell-Sorbie potential function for He-HCl system by applying the interaction energy data, which are calculated at the theoretical level of the single and double excitation coupled-cluster method with noniteractive perturbation treatment of triple excitation CCSD. The new potential model is compared with other potential models. The differential scattering cross sections for collisions between He atoms and HCl molecules are calculated by using CC (Close-Coupling) method. Furthermore, the changing regularity of the inelastic differential scattering cross sections is summed up.

根据在CCSD/aug-cc-pVQZ理论水平下计算的He-HCl相互作用能数据，作者采用Murrell-Sorbie势函数形式拟合了He原子与HCl分子相互作用的各向异性势，并与其它势模型进行了比较；然后采用公认的精确度较高的CC近似方法计算了He-HCl碰撞体系的微分散射截面，总结了非弹性微分散射截面的变化规律。

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。
