The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

In 1943 he was accused of fathering a child; the papers made much of the scandal, but it was proved in a court trial that he was not the father. The same year he entered his fourth marriage, to Oona Chaplin, daughter of playwright Eugene O'Neill. They had eight children. Tired of political and moralistic controversies and plagued with tax problems, he left the United States for Switzerland in 1952. He published his memoirs in 1964. In 1972 he returned to Hollywood to claim a special Oscar honoring his lifetime contributions to movies. He was named Knight Commander of the British Empire in 1975. He died in his sleep from old age.

卓别林第一部电影长片是1921年《寻子遇仙记》，两年后他为联美公司亲自监制、执导了《巴黎一妇人》，1925年和1928年又先后推出经典之作《淘金记》和《马戏团》，在1929年的第一届奥斯卡上，《马戏团》一片为他赢得"集编剧、表演、导演和制作于一身的多才多艺天才"特别大奖。1932年，卓别林从伦敦返回美国后，推出了他最成功的作品之一《摩登时代》，此后是1940年讽刺纳粹政权的的《大独裁者》。

一种延长加氢-氧化催化剂寿命期的方法，该催化剂在比如硅钛酸盐或分散在氧化硅上的钛的上面优选含有金、银或它们的混合物，以及任选的一种或几种促进剂。

Wei Chi Yabo: Record lifetime cent is a lot of kinds, one kind is us so called real group, we do travel of community of an Olympic Games, we have countrywide competition, had the throughout the country each match, or Chinese star baby waits these on-line activities a moment, long still is the contact that should have a kind of sth used to one's own advantage, this is electronic business affairs, what electronic business affairs wants to true tradition does a backing is abiding, I feel domestic disappear provides those who consume power most between all websites painfully.

尉迟亚波：记录一生分为很多种，一类是我们所谓的真实的群体，我们搞一个奥运社区行，我们进行全国的比赛，进行了全国各项的比赛，或者是中国明星宝贝等等这些线上的活动，长久的还是要有一种资本的往来，这就是电子商务了，电子商务要有真实的传统做一个后盾做的持久，我觉得家庭的消费力在所有的网站之间最具消费力的。

The expedition had taken with them an elderly Arab whose main qualifications as a guide were that he had crossed the sand sea twice before in his lifetime, once as a young lad. To the expedition's amazement , he had kept the vehicles at an exact compass bearing right across the sand sea, apparently based solely on his recollection of minor features in the landscape (a hump on the horizon or a patch of unusual red sand) that he had seen only twice many years before.

该远征队随行带上了一位年长阿拉伯人，他作为向导的主要资格就是他平生曾两次穿过这个大沙海，其中一次他还是个年青小伙子，令远征队叹服的是，他带领车队迳直横穿沙海时与罗盘方向完全吻合，显然他全靠回忆那些只在多年前见识过两次的细小的地貌特征(如地平线上的一个土丘或者一片非同一般的红色沙漠)。

Thinking of presenting problems, this research mainly studied some solid base catalysts which own higher catalysis ability and longer lifetime. Then, the phase diagram and equilibrium data of oil-alcohol-biodiesel-glycerol multiphase system were measured because the biodiesel producing process lacks of thermodynamic data.Based on a double-membranes theory and the thermodynamic data, a kinetic model was proposed. In addition, a mult-step extraction process was proposed to dispose the jatropha curcas l oil with high acid value in order to decrease the acid value. Then, a new technology of biodiesel producing using solid base as a catalyst was developed. The study objects and results are as follows.
