大角度的

Group is an important concept in Modem Algebra. Viewed from a different angle it may be divided into two different categories: finite group and infinite group; and Abelian group and non-Abelian group.

群是《近世代数》的一个重要概念，从不同的角度出发，群可以分为有限群和无限群两大类，又可以分为交换群和非交换群两大类。

Combining the experimental results and theoretical analysis, the following work has been accomplished.(1) Reasons of the decrease of interelectrode capacitance and the increase of discharge gap caused by the powder suspended in dielectric fluid are explained. And the mechanism that surface quality of workpiece improved by powder-mixed EDM is analyzed from this viewpoint.(2) The variation regularity of the percentage of silicon on the machined surface of workpiece has been summarized according to the experiment results when silicon powder was added into the working fluid. The entropy is introduced to explain the reasons for this variation regularity by thermodynamics.(3) The dimensional accuracy is greatly influenced by the overcut resulting from discharge gap and electrode wear in practice application. Empirical formulas for the overcut in EDM and powder-mixed EDM are established based on the experimental results using the ternary linear regressive method in this paper.(4) The influence of main factors on the machined surface characteristics has been evaluated based on the orthogonal experimental design method.

通过一系列普通电火花加工与混粉电火花加工的对比实验，运用工艺实验和理论分析相结合的方法，重点做了以下工作：(1)探讨了粉末颗粒导致极间电容减小、放电间隙增大的原因，并从这个角度解释了混粉电火花加工可以改善工件表面质量的机理；(2)以混合硅粉的电火花加工为例，实验得出峰值电流和脉冲宽度对加工表面层成分中硅元素含量的影响规律，并引入熵的概念从热力学的角度对硅元素含量变化的原因寻找了理论依据；(3)在实际加工中，由于粉末的加入使放电间隙变大，这使得混粉电火花加工的尺寸精度难以控制，本文利用三元线性回归的方法，在实验数据的基础上，建立了两种电火花加工过切量的计算公式；(4)将正交试验法应用于混粉电火花加工实验研究，并通过对实验指标极差的直观分析，得出各电参数对加工指标影响的敏感程度。

Alternatively, if the three Gunas – Sattva etc.– are identical with Mahat etc., they should, like Mahat etc., be constituted by the combination of three things. Applying the same process of reasoning as above, we can prove that they are not eternal, but, like Mahat, subject to change.

从另一角度来说，如果贪、嗔、痴三德就像大等二十三法一样，是由三事所构成，那三德也就是二十三法，由以上所说的，同理可证明，它们都不永恒，像大等二十三法，是在变易中的。

Some conclusions are drawn from the calculating results: when buried pipes cross fault, pipe's embedded depth should be shallow, and big pipe diameter and thick wall should be selected. Avoid the site where fault moves severe, and select suitable pipe-fault angle. Bigger pipe-soil friction coefficient is helpful for buried pipe crossing fault. Under dynamic loading, buried pipe would first damaged in compressive region of bilateral fault, so special treatment should be done to pipe in bilateral fault region.

依据计算结果分析了各因素对地下管道破坏的影响，并得出几点结论：管土摩擦系数较大情况下，管道破坏较轻；地下管道在穿越断层时，管道宜浅埋，并选取大管径、壁厚的管道；应尽量避开断层错动较大的位置，并选取合适的管道穿越断层角度；在受动荷载作用时，管道在断层两侧受压区先破坏，故在断层两侧要进行特殊处理进行防护。
