So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.

Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.

" The Greek military leader and historian Xenophon, who served with Greek mercenaries in Persia, first used the Greek word paradeisos adopted from the Avestan word to refer to the Persian kings' and nobles' parks or pleasure grounds. This Greek word extended to mean "garden" or "orchard was an obvious choice for translators of the Bible into Greek to use both for the Garden of Eden and the Abode of the Blessed, or heaven. The Greek word was adopted into Late Latin and was used much as we might expect in its biblical senses in ecclesiastical Latin. The Old English word paradis taken from Latin is found, but our word probably really established itself in Middle English (first recorded before 1200), derived both from Latin and from Old French, which had adopted the word from Latin. paradise.

曾随希腊雇佣军到波斯服役的希腊军事将领和历史学家色诺芬，首先使用了希腊语词paradeisos，，该词采用了阿维斯陀词，指波斯国王和贵族们的花园或游乐场，这个希腊词衍生到表示&花园&或&果园&，显然是译者在把《圣经》翻译成希腊文时所做出的选择，以用来表明伊甸园和天国或天堂，有这两种含义的希腊词被引入后期的拉丁语中且当它们在教会拉丁文（后期拉丁语paradisus 中意为《圣经》方面的意义时被更广泛地使用，古英语paradis 一词来自拉丁文，但我们用的这个词可能在中古英语（首次记录在1200年前）中真正确立了起来，人们发现它源于拉丁文和从拉丁文中采纳了这个词的古法语
