Advancing the temperature can increase its molecular weight, the best reaction temperature is 60℃, following by IR, the mechanism of HC1 is the hydrolyzation of alkoxy in 1 hour, and then condensation reaction.

升高温度有利于生成大相对分子量的聚合物，其水解缩合的最佳温度为60℃，通过IR对反应物的跟踪，在水解缩合过程中盐酸作为催化剂先是烷氧机硅烷的水解作用，1小时内就可以完成，之后再发生缩合反应。

The string-passing braider is the main equipment to strengthen the inside layer of the rubber piper formed by squeezing out the gum. It is urgent to study and produce the braider with modem productivity in China.

过线式编织机是一种用于对冷喂料挤出成型胶管进行内层增强层施工的主要设备，现急需研制我国自主生产具有现代生产能力的编制机。

The string-passing braider is the main equipment to strengthen the inside layer of the rubber pipe r formed by squeezing out the gum.

At the same time, some defects are pointed out: present fabrics are not properly applied, and most of looms can't produce woven perform whose property is similar in different directions. Their shearing strength are lower, utilization of mechanical properties are also smaller;Although three-dimensional braided composites is of excellent integrated structure, normal braided fiber is traveled from internal to external surface, which is passed through braider and becomes three-dimensional structure. If the external surface is cut or rubbed , it's possible for the fiber to break down. In addition , the shape of perform is easily changed after it's finished . To deal with respective shortcomings and highlight their own advantages, we're searching a new weaving method which is the combination between weaving and braiding .

但它们各自也具有许多缺点：目前机织物适应性不够，大多数织机还不能加工三维各向同性的机制预型件，材料剪切性能较低，力学性能利用率低；三维编织复合材料虽然具有良好的结构整体性，但常用的编织都是纤维从内表面穿到外表面，即穿过编织件的断面成三维结构，用这种方法制成的结构，如果外表面受到摩擦或切割损伤，就有可能导致结构的解体，此外编织结构的织物易变形，所以我们需要考虑一种新的结构，能同时发挥各自优势，又能同时克服二者缺点，这就是机织与编织结构相结合的方法。

The anterior clinoid process and roof and lateral crista of optic canal were drilled off intradurally to display proximal angle of the aneurysm in the cases of paraclinoid aneurysms.

术中采用逆向抽吸法使动脉瘤塌陷，如动脉瘤内含机化血栓，则在临时阻断后切开瘤体，用CUSA和取瘤镊去除瘤内血栓，再将动脉瘤夹闭并达到视神经减压的目的。

Objective To compare the changes of the number of the blood cell and coagulatory functions in the intracavitary blood before the use of Autologous Blood Recovery System and after.

目的 比较自体血液回收机处理前后胸/腹腔内积血血细胞数量和凝血功能变化的特点。

The Grafting automatic machine is the cucurbitaceous vegetables which seedling in nutritional bowl.. It solves a difficult problem in vegetables' grafting., therefore, has high value for use in vegetable production.

本次设计的自动嫁接机针对的是采用营养钵育苗的葫芦科植物，实现了砧木苗在营养钵内无需拔苗即可直接的操作，有助于嫁接以后苗的恢复，在生产中具有较高的使用价值。

Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

戊n体编辑，并以蒙地卡罗方法模拟，模拟结果以叙述统计呈现；最后以两个&投入式&组立设计的镜群组为案例，计算镜片在镜筒内的累积偏心角度公差、偏心距离公差及镜片光学轴的累计偏移量，其结果显示该模型可模拟一个镜头系统的关键品质参数；所以，镜头系统的性能在大量生产之前可藉本光机公差模拟模型预测其品质与良率。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
