This paper incends to give a comprehensive survey of the high encrgy nuckar interactions produced in emulsions and cloud chambers by particles of an energy in the range 10~21 to l014 cV. The more difficult problems of measurement, such as determination of the primary energy, identification of the secondary particles and estimation of the target mass, are first brought up for discussion. Effort has been made to explain whenever possible the physical meaning of the quantities, which may give information concerning the collision mechanism and hence the internal structure of the colliding particles. The main quantities or these arc the angular distribution, the transverse momentum and the inelasticity, in addition to the multiplicities of the different kinds of the secondary particles. For these quantities, the principle of measurement, the accuracy of experiment and the meaning of the results, particularly the latter, have been emphazised and discussed in some detail. Finally, the various models of the "one emitting centre" and of the "two emitting centres" arc discussed entirely from the physical point of view and are compared with the experimental results. It is hoped that this paper may present a general picture of the recent development of the high energy nuclear interactions and indicate the problems siill remained to be sclved.

这篇总结性文章叙论了由能量高到10~(11)—10~(14)电子伏的粒子在乳胶和云室中所引起的高能核作用。文中首先提出和讨论了在测量上较困难的一些问题,例如,初能量的测量,次粒子的辨认和靶质量的估计。一些可能揭示碰撞机构从而显示核子内部结构的物理量的物理意义,也适当地加以讨论和阐明。除了不同次粒子的多重性外,主要的物理量是:次粒子的角分布、它们的横动量和非弹性系数。关于这些量的测量原理,实验准确度和实验结果的物理意义,特别是后面一点,都有了较充分的检查和讨论。末了,“一个发射中心”和两个发射中心”的各种模型也从物理观点作了较定性的描述和讨论,并和实验结果作了比较。希望通过这篇文章对高能核作用目前发展的概况、尚存在的问题及今后工作的方向能有一定的了解。

In this paper, we suggest one method of finding the Green tensor functions in whole space, which are defined in formula (3). Some times it is also called the elementary solution of the corresponding differential equation. All this method is based on Fourier transform. Owing to complexity, we are obliged to make some simplifications. Magneto-gyrotropic media and electric-gyrotropic media are considered separately. For magneto-gyrotropic medium, such as ferrite, μ, is a tensor while s remains scalar. Conversely, for electric-gyrotropic medium, such as plasma, e is tensor and μ remains scalar. Taking advantage of the smallness of matrix μp (defined in (15)) we make an expansion in power series of μp, and carry out the calculations in first order approximation. The concrete results are expressed in formulae (23)、(25)、(28)、(32) and (33). The physical meaning of Γ and the effective region of the asymptotic expansions are discussed.

本文提出一个方法,来推求在(3)式中所定义的、在全空间中的格林张量函数。它有时亦称为对应微分方程的基本解。这个方法是以富氏变换为基础。由于问题的复杂性,我们不得不作某些近似。首先,把各向异性介质分为两类,一类是磁迴旋介质,另一类是电迴旋介质。对于磁迴旋介质,如铁氧体,取为张量而ε为标量。而对电迴旋介质,如等离子体,取为张量而μ为标量。其次,由于矩障非常小(在(15)式中定义),我们可以把解展为的冪级数,并计算出一级近似。具体结果在式(23)、(25)、(28)、(32)和(33)中表示。最后对Г函数的物理意义和它的渐近展开式的有效范围作了讨论。

Electron-optical instruments (e.g. the electron microscope) with high resolving power require strict rotational symmetry in its electron lens system. But in a real system there exist defects in this symmetry, among which the effects due to pole pieces of inclined end faces remain to be studied.This paper investigates the electron optical aberration due to such defect. Method of separation of variables is employed to obtain an exact analytical formula of the scalar potential field. Paraxial electron trajectories of the lens are calculated. Aberration characteristics is analyzed in detail. As a conclusion, the tolerance for inclination of the end faces of the pole pieces is given, which lies well within limits of normal workshop practice.Methods of study and the results thereby obtained are also applicable to an electrostatic lens system.

高分辨本领电子光学仪器(例如电子显微镜)要求电子透镜具有严格的旋转对称性,但是实际的电子透镜存在着非旋转对称的缺陷,从而影响了仪器的质量。在这些缺陷中,极端头的端面倾斜目前还没有研究过。 本文计算和讨论了磁透镜极端头端面倾斜所引起的电子光学象差,作者应用数理方法(分离变数法)得到了端面倾斜情况下场分布的严格解析表达式;当倾斜为微扰时计算了非旋转对称象差以及它们与几何参量的关系;得出了高斯象平面上轴上象散圆斑大小;最后讨论了高斯轨迹的微扰及其象差图形。结果表明:轴上象散椭圆斑和端面倾斜角度正切的平方成正比,由此给出了极端头端面倾斜的加工容差。 本文所用方法与所得结果均适用于研究静电透镜。
