For general engineering problems, the analytical transformation rules are sufficiently accurate to design the similar cascade profile, but further improvement of the precision is limited by the one-dimensional assumption of the transformation, therefore an inverse blade design method—influence matrix method, based upon the surface vorticity model, is developed to improve the precision effectively.

进一步讨论了在具有相同表面压力系数分布的情形下，进口马赫数对附面层发展的影响，发现在一定条件下，只要表面压力系数的分布相似，则叶面附面层发展情况及无量纲气动力参数也将存在相同精度的相似，这一结论使我们在进行相似流场模拟的模型设计中，得以只进行无粘流场之间的相似变换，从而大大减少相似模型设计的工作量和复杂性。

This paper gives a simple idea about the problems existing in students' writing: 1 psychological blockage, such as anxiety, lack of interest so on and so forth. 2 Chinglish frequently appears in Chinese students' composition. That is to say Chinese students often use Chinese way of thinking to writing English composition. 3 When Chinese students write, they usually commit intralingual error. Intralingual error is the mistake that students often make when they choosing words, making sentences. It also includes grammar mistake. 4 Chinese students often don't know how to organize the ideas when they face the composition topic. As a result, the compositions written by most of Chinese students don't have clear topic sentence. 5 Chinese students' compositions are usually very boring and dull. Based on the problems that exit in Chinese students' composition, this paper put forward five teaching strategies: 1 English teachers should foster positive emotion when they teach writing.

本课题简单阐述了中学生英语写作中普遍存在的5个问题：1、对英语写作存在心理障碍，比如畏惧心理等；2、中学生英语作文存在大量"中国式英语"，即学生经常借用汉语思维进行英语写作，使得文中出现不符合英文习惯的句子和表达；3、中学生在进行英语写作时经常犯言内错误，言内错误指学生在用词，造句及句法等方面经常容易犯的错误；4、中学生在面临所给的作文题目时不知道如何审题，写出来的作文中心思想不明确；5、中学生英语作文普遍存在内容单调贫乏的问题。

The formulae were derived to calculate the spherical coordinates of any vector after the specimen was rotated any angles around any axis based on the homogenous coordinate theory.

摘 要：在利用同步辐射进行晶体缺陷的形貌研究时，为了获得晶体缺陷的三维分布信息，在实验中样品要在样品台上沿不同方向旋转轴进行多次旋转，因而需要计算样品经过多次旋转后任意矢量的空间坐标以及缺陷的取向坐标。

Starting from the traditional theme of disinterested pleasure, it re-evaluates two essential prepositions in the academic discussion of experience of beauty, that is, the necessity of disinterestedness and the undesirable or even damaging role of sensory pleasure. On the basis of these observations, this dissertation goes on to unearth and finally recover the essential factors engaged in the experience of beauty.

本文从对传统的"审美是无功利的快感"这一基础命题的怀疑出发，对命题中的无功利在审美中的必要性问题和感官快感对审美的损害问题重新进行审视和质疑，并在此基础上展开对审美的情感的微观分析和理论推导，将审美的情感中所涉及到的因素清晰化。

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是靠模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的靠模，加工时把工件毛坯和靠模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动，从而切割出与靠模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作靠模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴，是由前苏联人发明的，我国是第一个用于工业生产的国家，当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型，我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS

Besides, the researchers also indicate that under different market structure, the property and degree of scale economy is different.

本研究结合市场经济与规模经济从理论及实证两个方面进行分析，其研究结果显示，在完全竞争的市场结构中，规模经济是不确定的，而在不完全竞争的市场结构中，不仅存在规模经济，而且企业存在最小最佳规模，达不到有效规模的企业在竞争中处於不利地位。

Breakeven Point and Sensitivity analysis were revised to make the risk evaluation properly and scientifically. The evaluations of the probability analysis of random risks were analyzed in the way of the theoretical probability and Monte Carlo simulation. And the application of gray prediction can make up the lack of data. 5. For the risk assessment of the real estate investment, the fuzzy math and the gray cluster were applied to reduce the influence of the subjective factors in the risk measurement.
