Day, he one when hunting in the forest,he caughtsight of artemis'' fair maidens,the seven pleiades .hewas so attracted by their beauty that he started chasing them.indespair the charming maidens prayed to artemis for help and were sent up by the goddess to the heavens as a constellation .later he fell in love with another maiden,merope by name,butrash and impatient,he took the maiden by force and enraged her father,king oenopion of chios.the king made him drunk and put out his eyes .following the sound of the cyclopes'' hammer,he went to hephaestus,who sent a guide to travel with him to the east,where the sun rose.exposing his eyeballs to the rays of the sun,he was restored to his eyesight.he became aconstant companion of artemis and followed the goddess in the chase with his dog sirius.apollo did not approve of this love, however.one day he dared his sister to shoot at a dark spot moving in the sea.little did she suspect that she was aiming herarrow at orion,for the dark spot turned out to be the head of orion swimming in the ocean.artemis was extremely sad.as she could not pull him back from the grasp of death she sent him up to the sky as a constellation,with his hunting dog sirius be sidehim.

他是海神波塞冬漂亮的儿子。一天，他在森林中打猎，看到了阿尔特弥斯的仙女们——七颗明星。他如此爱慕她们的美丽，便追赶她们。困境中，美貌的仙女们向阿尔特弥斯求救。结果女神将她们都送入天空充当星座。后来奥利安爱上了另一少女墨洛珀。他鲁莽急躁地施暴于她。这激怒了少女的父亲俄诺皮耳国王。国王把他灌醉后，挖出了他的眼睛。随着"独眼巨人"大锤的敲响，他来到火神赫斐斯托斯跟前。火神派向导带他去太阳升起的东方。将眼球暴露于阳光后，他就恢复了视力，成了女神阿尔特弥斯永久的伴侣，并带着他的猎狗天狼跟随女神打猎。阿波罗并不赞成他们之间这种恋情。一天，阿波罗怂恿阿尔特弥斯向海中一移动的黑点射箭。她根本没想到自己是将箭瞄准奥利安。当看清黑点竟是在游泳的恋人奥利安的头时，阿尔特弥斯悲痛万分。因她无力使他起死回生，只好将他送入天空作一星座。他的猎狗天狼则蹲在他的身旁。

Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.

MARC存在的粉末材料模型方面的设计缺陷后，对连铸水口粉末成形件的变形规律及影响因素作用进行了模拟分析，指出芯棒形状对成形件的变形有较大影响，并且芯棒顶部形状与芯棒底部形状相比，对粉末变形有更大影响；(3)分析了成形件出现低密度区域的原因，指出模具形状对粉末流动以及粉末成形件低密度区域的形成有重要作用，提出了密度分布优化改进模型：改进模具顶部形状，并将芯棒顶部设计成球面后，粉末成形件顶部区域的应力、应变分布更加均匀、合理，粉体颗粒流动情况明显改善，低密度区域明显缩小；(4)计算了成形件的尺寸精度及切削率，并指出除模具形状的影响外，充填密度、橡胶模具老化、加载工艺等其他因素对总体切削率也有相当的影响。

The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。

Such doubts havesitimulated the researchers'curiosity and start to explore the students' terms This research proceeds by observation interview test using learning sheets and etc The purpose is to explore students' terms of scientific concepts sources of terms connections between students' usage nomenclature and chooses of usage The results of the research are as follows: 1 There are five kinds of naming principles for students' terms of scientific concepts: appearance habit function replacing and sound Appearance principle contains three categories: color shape and partial construction; habit principle contains custom and ability; replacing principle contains reality and non-reality 2 Students' terms of scientific concepts come from two ways: self-acquisition and learning through senses The former way is only a bit more common than the latter 3 There are three different relationships between students' usage of terms and nomenclature: one both the same in usage and meaning; the other both different; another different usage but the same meaning Normally terms that students used are various from nomenclature in the aspects of usage and meaning only a few would match and even rare for "Synonyms" to occur 4 Alternative options for students' scientific terms are maintenance adaptation or co-existence with formal scientific terms The most common way of selecting usage of terms is to maintain Sometimes students would adapt themselves once learn of scientist's term However some believe that very odd chances for both could exist at the same time

这样的疑问深深引起研究者的好奇，著手探索学生科学概念所使用的语言。本研究透过观察、访谈、学习单施测等方法来进行，目的在探讨学童在科学概念上所使用之学生惯用语、学生惯用语来源、学生惯用语与科学家用语之关联性、学生惯用语选择。研究结果如下：一、学童在科学概念上所使用之学生惯用语的命名原则有五种：外型、习性、功能、藉代称呼及声音，其中外型原则有颜色、体型及部份构造三类目，习性原则有习惯及能力两类目，藉代称呼原则有实体及虚拟两类目。二、学童在科学概念上所使用之学生惯用语有两种来源，分别为自己称取和听来。学生惯用语来源较多为自己称取，透过其他方式听来少一点，但两种来源的比率差距甚小。三、学童在科学概念上所使用之学生惯用语和科学家用语的关系有三种，分别为用语意涵均相同、用语不同意涵相同和用语意涵均不同。学生惯用语通常和科学家的用语是不同的，且其意涵也不同，只有部份学生惯用语和科学家用语意涵均相同，至於学生惯用语和科学家用语不同但意涵相同的极少。四、学童的科学概念相关学生惯用语选择有三种，分别为维持学生惯用语、改变成科学家用语和科学家与学生惯用语皆可。学童的科学概念相关学生惯用语选择，以维持学生惯用语最多，而有些时候学生会在得知科学家的用语后改变成科学家用语，但认为科学家用语和自己使用的学生惯用语皆可的则很少。

XRD and EDS analysis indicate that at static condition, the composition of the scale is CO3, while the scale changes to CO3 at dynamic conditions. The increment in flow rate increased the thickness of the scale remarkably, but had little influence on the hardness and Young's modulus of the scale. The fracture toughness of the scale exhibited the lowest value at the flow rate of 0.5 m/s whereas the adhesion strength increased with increasing the flow rate.

结果表明，静态条件下形成的腐蚀产物膜的主要成分为CO3，动态条件下的主要成分为CO3；介质的流动能够促进腐蚀产物膜的形成，但对膜的硬度以及杨氏模量影响不大；腐蚀产物膜的断裂韧性随着流速的增大先下降后上升，流动状态下内层腐蚀产物膜的致密性较好，膜与基体的结合强度较高。

The microsturcture characteristics of M2 cast-strip were studied with such experimental methods as metallographic analysis, SEM, XRD and TEM[0]. The effect of sub-rapid solidification on the size, type and distribution of eutectic carbides in M2 cast-strip was analyzed. The effect of heat treatment temperature and its holding time on the eutectic carbides in M2 cast-strip was explored. The eveolution of metastable phase of M2C eutectic carbide during the heat treatment period and the decomposition dynamics concerned were researched. The M2 cast-strips were rolled into thin strips and the effect of deformation ratio on carbides in M2 cast-strip was examined. Then these thin strips were comparied with those that were produced by conventional technology on carbide, hardness, red-hardness and bend strength. At last the rolled M2 cast-strips were made into saw blades and their cutting performance was experimented on in tools factories and then compared with that of similar products produced by conventional technology.
