PVA-2080 is one of the important dispersing agents to produce loose polyvinyl chlorid. At present KH-20 is mainly imported from Japan to take the place of the traditional gelatin to produce high quality PVC in our country. In order to solve this problem, we exploit PVA-2080 to replace the foreign products. The experiment includes two steps of polymerization and a process of partial alcohlysis. After a number of trials, we get a product of white particles.Its average degree of alcoholysis is 80.77% and t...

聚乙烯醇- 2 0 80 (PVA - 2 0 80 )是生产疏松型聚氯乙烯的重要分散剂之一目前，国内主要依靠进口日本的KH - 2 0以代替传统的明胶来生产高质量的PVC产品为了解决这一问题，作者开发了PVA - 2 0 80 ，以代替国外进口本试验经过两步聚合和部分醇解等过程，通过正交试验优化试验条件，得到了外观为白色粉末状颗粒、平均聚合度为 2 0 4 2、醇解度为 80 。77%的产品经小釜应用试验，效果比较理想

Result proves that ultrasound frequency is higher in the same time, lethality rate increases with the increase of radialization time on the same frequency, at the same time, its physiological character changes.

试验结果表明，在相同的时间内，超声波频率越高对试验菌株的致死率越高；同一频率，超声波辐射时间增加也可使试验菌株的致死率增高，同时经过诱变处理后的菌株其生理生化特性也有变化

After looking up a large amount of native and foreign information, the materials used in the experiment were as follows: PTFE base, graphite filler, molybdenum disulfide filler, copper powder filler, carbon fiber and so on. The experimental method is that the formula was designed according to uniform experimental method, the relationship between formula and frictional property was found with spline function and then the representative test points were chosen from fitting curve to make verification test for optimization.

经过查阅大量国内外文献资料后确定原料为：聚四氟乙烯树脂为基体，加入石墨、二硫化钼、铜粉、碳纤维等填料；试验方法为：根据均匀试验方法设计配方，用样条函数找出配方与摩擦性能的关系，然后在拟合曲线上选取具有代表性的试验点进行验证试验，达到优化的目的；制备工艺：冷压烧结法制备固体润滑剂。

The study found that free-stage has no effect on performance, to be end as soon as possible; the pressure and oil-filling time in oil-filled stage are the key, which directly determines the speediness of the starting; slipping-stage decides the comfort of the starting, and the friction coefficient is important for this stage, synchronous engaging-stage don't product slipping loss, and don't impact the jerk of the vehicle, needing to be finished fast. According to control object and evaluate guidelines, the fuzzy control algorithm is developed and different experiments verify the correction of algorithm.5 With the debug of CVT control software, the experiment is finished in two years which includes test bench experiment, 60℃high temperature test in Tulufan of Sinkiang province, 4647 meters high altitude test at Kunlun mountains, as well as the minimum temperature of -32℃test at Heihe.

根据控制目标及评价指标，开发了湿式离合器接合过程模糊控制算法，各类试验证实了算法的有效性。5湿式离合器的起步试验伴随CVT控制软件的调试，历时二年，经过台架试验，新疆吐鲁番环境温度高达60℃的高温标定试验，昆仑山口海拔高度4647米的高原标定试验，以及黑河最低温度为-32℃严寒标定试验，所取得的研究成果对离合器软件开发和标定流程具有很好的借鉴意义和工程应用价值。6自动变速器起步离合器的标定是软件产品开发的核心技术。

Basket Deep Sea Fish Oil Soft Capsule is the only national health food products through the blue hat functional tests to prove that its main ingredient EPA, DHA could improve memory and function of regulating blood lipid health food, soy lecithin soft capsule has also been functional tests to prove is capable of regulating blood lipid health care function.
