碰撞理论中的一定条件下互碰次数的Z_(AA)的求算公式,,国内外教材里五花八门,若干印刷成册的题解也均如此。公式颇大,系数较繁,出发基点不同的公式里系数差别不一。要临时推导,很费精力。同时,不同的公式中,系数来源的理解基点也不一样。使读者在翻阅各类参考书时造成极大的混乱和不变。在某些支节处,国内外教材且说法不一,故立题讨论。
Collision theory under certain conditions, the number of contact each Z_ (AA) of the formula, a variety of teaching materials at home and abroad, a number of printed volumes of the questions are also true. Formula is quite large, the coefficient of more complex, the starting point of the different coefficients in the formula vary. To be derived temporarily, it is laborious. At the same time, different formulas have different understanding of the origin of the coefficients. So that readers in reading all kinds of reference books caused great confusion and change. In some branches at home and abroad teaching materials and different opinions, so the discussion.
