In this paper a new bag model of hadrons,the“Rubber Bag”model,is proposed.This model treats each hadron as a bag system in the centre-of-mass frame.The bag,with its outer radius R_e and inner radius(R_c-D),is characterized by its“averagesurface tension”T and the quarks are confined in it“temporarily”.This model isa field theoretical model which can also be used for quantitative calculations.Thus,ithas the merits of the SLAC bag model as well as those of the MIT bag model.

本文提出一种新的强子袋模型(“橡皮袋”模型).根据这个模型,在质心系中,强子可以形象地看作为一个外半径为 R_c,“壁厚”为 D,“平均表面张力”为T 的口袋体系;夸克被“暂时”禁闭在袋内.这个模型兼有 MIT 和 SLAC 二种袋模型的优点,它既有场论基础,又能用来进行定量计算.

If the evaluated data for elastic scattering angular distribution is given intabular form of two dimensions in either the laboratory or the center-of-massframe of reference,the data can be respectively transformed into Legendre poly-nomial expansion in either laboratory or the center-of-mass frame of reference.The transfer method of angular distribution function of one dimension in re-ference[1]is applied to the transformation of two dimensions.

There are a lat of branches in the theorem of kinetic energy, the reason why the branches are formed is that the definition of kinetic energy is not clear. In the paper, it is put up that the definltion of kinetic energy is only determined in the Centre-of-mass frame, also, the theorem of kinetic energy is simplified.

力学的三大基本定理之一——动能定理,有许多不同的分支,这是由于没有弄清动能概念的定义式造成的,本文阐明,动能概念的定义式只能由质心系确定,从而达到简化动能定理的目的。
