This paper presents the solution of the eigenvalue problem of the three dimensional two-groups neutron diffusion equations using finite element method. An iteration scheme, proposed by Lin Qun, for improving the convergence is studied and applied. On this basis, a general code is developed which uses three dimensional isoparametric elements with 20 and 15 nodes, rectangular prism elements with 8 nodes, triangular prism elements with 6 nodes.

The author of this paper attempts to discuss the problemsconcerning communication between teachers and students from the angleof socio-psychology, holding the view that the structure of communicationbetween teachers and students in the course of teaching is composed ofthree principal aspects-intefaction, exchange of information, and mutualrecognition, and of three principal levels-personality, role and comm-unity. Therefore, the author proposes a communication pattern called"triangular prism of three aspects and three levels." Each of the three aspects in this pattern consists of some factors,and each factor plays a role in the communication between teachers andstudents on every level. Various problems may occur on every aspectand on every level which would affect the process of education. In thispaper, a preliminary analysis of these problems is made and some generalsolutions to them are also suggested.

本文尝试从社会心理学角度探讨师生交往问题,认为师生在教育过程中的交往结构,是由相互影响、信息交流、相互认识三个主要侧面和个性、角色、群体三个主要层面构成的。据此,笔者设想了一个“三侧面三层面的三棱柱体”式的交往模型。 这个模型的三个侧面都可分析出一些因子,每个因子都能在各个层面上展开师生交往。在交往的每一侧面和层面发生的各种问题,都会影响教育过程的进行。本文初步地分析了这些问题,并概略地指出了一些解决办法。
