General clue of this paper is simulating wood stress field change in initial cutting stage and working out weighted boundary condition of cutting tools first,and then based on which, finding out shear stress and maximal effective stress when wood cut-ted.Meanwhile,finite element comparative analysis is proceeded on distortion and stress field by changing tool orthogonal rake.

本课题的总体思路是通过大型有限元软件ANSYS来模拟切削初始阶段中木材的应力场变化，进而得出刀具受力的边界条件，依此为基础求出木材受切时的剪应力及最大等效应力，同时通过变化刀具前角分别对受切工件的变形及应力场进行有限元比较分析，从而确定刀具的优化前角；优化前角确定后，再通过对刀具进行强度校核确定后角优化值。

The study of impact of dirt band on top coal drawing mining;2. The paper has studied the caving characteristics and technology on the fully-mechanized caving mining working face in structural complex thick seam containing dirt band are studied.

通过对综放工作面含夹矸结构复杂段顶煤放出特征和放煤工艺的研究，提出选择两刀一放单轮间隔放煤方式，有利于提高煤炭回收率，降低原煤含矸率。

Based on the theory study, a directional drilling guidance system is developed for practical require, its working flow as follows: before construction, design the best track practically, and save in the system. During drilling, the system measures well oblique angle and azimuth to watch well track. Drill driver compares designing well track with measuring track showing on display unit, controls joy stick experientially, adjusts drill direction, finally realizes directional drill.

在理论研究的基础上，结合实际需要，研究设计了一种定向钻井导航系统，使用该系统进行定向穿越施工的工作过程如下：在施工前，根据实际情况，先设计一条最佳穿越路线，存入系统；在钻进中，系统通过对井轨的井斜、方位等参数的测量，对其进行实时监测；地面的司钻手通过对显示仪所显示的实际井轨参数及设计井轨参数进行比较，根据经验操纵操作杆，调整钻机前进方向，以达到对钻进过程的控制，最终实现定向钻井。

There is no one kind of thing that we 'perceive' but many different kinds, the number being reducible if at all by scientific investigation and not by philosophy: pens are in many ways though not in all ways unlike rainbows, which are in many ways though not in all ways but not in all ways unlike pictures on the cinema-screen-- and so on, without assignable limit. So we are not to look for an answer to the question, what kind of thing we perceive. What we have above all to do is, negatively, to rid ourselves of such illusions as 'the argument from illusion'--an 'argument' which those (e.g Berkeley, Hume, Russell, Ayer) who have been most adept at working it, most fully masters of a certain special, happy style of blinkering philosophical English, we have all themselves felt to be somehow spurious.

我们&感知&到的不是唯一的一类东西，而是林林总总、纷繁各异的事物；它们的数目即便可以归约化简，那也应是科学研究而非哲学思考的任务：在很多方面，但并非在所有方面，钢笔异於虹霓，虹霓又在很多方面虽非在所有方面异於视觉后象，视觉后象又在很多方面虽非在所有方面异於银幕上的图像――如此等等，没有可以简单划分的界线。

Butmen have decided to go on strike next week.the strike is due to begin on tuesday.no one knows how long it will last.the busmen have stated that the strike will continue until general agreement is reached about pay and working condisions.most people believe that the strike will last for at least a week.

Man can create his own image through ark working such as drawing and caving from wood or stones, such as the images of great heroes sometimes use for decoration, symbols on logos and for religious purposes such as the brazen serpent of Moses, the two cherubs on the Ark of the covenant, the image of lions surrounding the throne of King Solomon etc but they cannot speak because there is no live in them.

人可以创造自己的形象通过方舟的工作，如绘图和放从木材或石头，如图像的伟大英雄有时使用的装饰，标志标识和用于宗教目的，如厚颜无耻蛇摩西，两个小天使的在约柜，狮子的形象，周围的宝座所罗门王等，但不能说，因为没有生活在其中。
