The results of prediction agree well with the experimental ones. It proves that the thermo-mechanical analysis、the neural network models of flow stress and microstructure as well as the numerical simulation system developed combining coupled thermal-mechanical rigid-viscoplastic FEM with BP neural networks are reliable to describe the hot back extrusion process of Ti15-3 alloy truly. The simulation system has good prediction capacity for the microstructure evolution of Ti-15-3 alloy during hot backward extrusion and after solution treatment. It can be used to replace the experiments for predicting the flowing laws and the distribution of microstructure.

由此证明，本文的热力耦合理论分析、流变应力及显微组织的神经网络预测模型以及采用三维热力耦合刚粘塑性有限元与三层向后传播的人工神经网络相结合的方法开发的Ti-15-3合金筒形件热反挤成形的显微组织数值模拟系统是可靠的，能够真实地描述Ti-15-3合金热反挤工艺过程，并对其反挤成形及固溶处理后的显微组织具有很好的预测能力，可以被用来代替预测其反挤成形规律和组织分布情况的试验。

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。

准备好绞索后，作为袭击者的你悄悄地从后方靠近目标，迅速用绞索套住目标的脖子，用力向后拉绞索的同时转过身把自己的臀部顶住目标的臀部，转身的同时绞索会深深的勒入目标的喉咙；当目标的重心完全放到臀部之后向上用力将目标从肩部摔出，目标将死于窒息或者脖子折断。

In my opinion, Lotmans view on text in his literary semiotic theory mainly demonstrates the structuralism style and characteristic, but in his cultural semiotic study the view on text has the more poststructuralism characteristic. This also reflects Lotman's ideology change in his semiotic study: transition from a structuralism to a poststructuralism.

在我看来，洛特曼的文艺符号学中的文本观主要显示出了结构主义的风格和特征，而他的文化符号学中的文本观则是具有了更多的后结构主义的特点，这也反映出了洛特曼符号学思想的变化性：由结构主义向后结构主义过渡。

Arethusa was once a fairy maiden huntress.she carriedbow and arrows for artemis in her hunting.she was sodevoted to her work that she cared for neither admirationnor love.one sunny summer day,she felt hot and found a coolstream quite attractive.she jumped into the delightful streamand happily started swimming.presently she heard a bubbling in the stream and was surprised to find it was the thunderingvoice of the rivergod alpheus.the maiden made for the shore and,fully naked,started running away.taking a human form,the river-god followed closely in pursuit .onward they spedover hill and valley,across dark heights and over broad plains,until the waters of the western sea lay stretched out right before them .helplessly the exhausted arethusa cried to her patronessfor help.artemis instantly cast a cloud over her body,but the pigheaded alpheus was not to be tricked.then a cold sweatbroke from the maiden''s arms and legs.the drops of water fellfrom all over her body.she had been turned into a spring!

阿瑞塞莎是位迷人的仙女猎人。每逢阿耳特弥斯打猎时，她负责携带弓箭。她对工作专心致志，既不考虑赞美也不顾及爱情。一个炎热的夏日，她感到很热，便找到一条凉爽的溪流，深感惬意。她跳入令人愉快的溪水中，兴致勃勃地畅游。不一会儿，听到水泡声，她大吃一惊地发现：那是河神发出的闷雷声。仙女向岸边游去，赤身裸体地跑开了。河神便装成凡人的样子在后紧紧地追赶着。他们一直向前飞奔，越过小山，跨过峡谷，翻越大山，掠过广阔的平原，直到西海的水域展现在他们的眼前。绝望中精疲力竭的阿瑞塞莎哭叫着向她的保护神求救。阿耳特弥斯迅速将一层云雾披在仙女的身上。但顽固不化的阿耳法斯并未上当受骗。接着一股冷汗从仙女的肢体上溢出，并且浑身上下淌着水珠，她被变成一眼泉水了。

采用在注蒸汽过程中向地层掺入稀油的方法来降低地层稠油的粘度，实验研究了超稠油掺稀油后粘度的变化，并按非线性混合方法计算了稠油与稀油混合后的粘度。

My days were not days of the week, bearing the stamp of any heathen deity, nor were they minced into hours and fretted by the ticking of a clock; for I lived like the Puri Indians, of whom it is said that " for yesterday, today, and tomorrow they have only one word, and they express the variety of meaning by pointing backward for yesterday forward for tomorrow, and overhead for the passing day."

我的日子并不是一周中的星期几星期几，没有被烙上异教徒神灵的印记，也没有被切分成一小时一小时，并且被时钟的滴答滴答声搅得心烦意乱。我喜欢像印度的普里人一样生活。据说，他们在表达昨天、今天、明天的时间概念时用的是同一个词，而在表达不同的具体时间概念时，他们就用手向后指来表示昨天，向前指表示明天，像头顶指表示正在过去的一天。

China accounting bookkeeping has gone through the initial phase, primitive phase (including single-entry and double-entry orderly in time),recent phase (i.e.phase in which bookkeeping-method of China style was reformed) and modern phase.

840年鸦片战争后新的环境使中国会计记账思想经历了一次磨难，曾一度被人轻视，改良中式簿记法的推行者们使之获得新生，形成了与西式簿记并存的近代阶段；新中国成立后，中国会计记账思想在与借贷记账的冲撞和交流中，逐渐与之接近乃至融合，最终完成了中国会计记账思想向现代化的转化。
