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。

This paper investigates topological properties of the general gradient system, and demonstrates by results of differential topology that the boundedness of the general gradient system is equivalent to the boundedness of the potential energy boundary surface. Moreover, a general gradient system is bounded if, and only if the system has both sink point and source point.

From four kinds of "positions", the new concept "Geographical Potential Energy" is introduced, which came from the geographical split and affected the diplomatism and the strategists' mentality and deeds.

作者由《战国策》4种"势"的情况中的地势，引出了"地理势能"这个新概念，认为地理的分裂造成了这种潜在的，势力量，从而形成了战国中的外文合和力与张力，对策士的心理和行为产生了影响，并因此造就了《战国策》中的一系列特征。

The results of experiments and analysis shown that the clay mineral is mainly gerundive, montmorillonoid is little, but a great quantity of sodium-ion in gerundive soil and larger pH make the soil as well as montmorillonoid which is intense dispensability, These are two keys for the soil to disperse.

试验和分析结果表明，土样中的粘土矿物主要以伊利石为主，蒙脱石含量较少；伊利土中含有大量的钠离子，使得伊利土象钠蒙脱土一样具有强分散性；pH值较高，使得土壤颗粒之间的净势能表现为斥力，这也促使土样土样产生分散性。
