ABSTRACT Aiming at problems of trans-vector controller in a vehicle-carried induction motor such as variable rotor and stator resistance following motor temperature, and their inductance varying with flux saturation degrees. Firstly, CSI and VSI are introduced, for CSI, it can hold the advantages both FOC and DTC using stator flux directional, PI parameter and simulation are also introduced. Secondly, equations of IM in the synchronous rotary frame and its static counterpart, as figuring in the saturation condition of magnetic field, are dealt in this paper and the simulation results are presented. Thereafter, the parameter designing of PI trans-vector controller is processed, which features the non-linear model. In practical realization, as neglecting the dynamical change of motor inductance, this paper employs online modification of inductance parameters, according to the flux saturation, then transforms the non-linear equations into linear ones, and so compacts the structure of controller. Thirdly, in view of the maximum torque output is extraordinary requisite when Electrical Vehicle start up, accelerate, and overtake, this paper issues the maximum torque when both inverter and battery capacity is corporeally definite. Fourthly, on-line differentiating and analyzing both rotor's time constants and its flux by using the expanding order reduction and discrete Kalman filter equation are fathomed, in order to realize high-performance trans-vector algorithm, and also the simulation results are presented. Fifthly, the close-loop regenerative brake system, when the EV's torque is set constant, is deduced; at the same time, unification of electric drive model and brake model is executed. Combined with maximum charge current demands, the mathematical model for online yielding torque as a demand.

摘 要：民间体育是指非官方的在民众中开展的体育活动，它不具有世代相传和延续的特点，可以在某一时期出现，又可能在某一时期消失；民俗体育是指那些与民间风俗习惯关系密切，主要存在于民间节庆活动、宗教活动、祭祀活动中，是一种世代传承和延续的体育文化形态，具有集体性、传承性和模式性特点；民族体育有广义和狭义之分，广义民族体育指曾在历史上反映和承载着一个民族共同心理素质、共同文化，为该民族享用的一种特殊文化，中华民族体育、古希腊体育、古埃及体育都是民族体育的具体表现形式，狭义民族体育是指近现代一个民族所独有的，反映并承载该民族共同心理素质、共同文化并为该民族所创造和享用的一种体育文化形态；传统体育是指由历史沿袭下来，是民族在漫长的历史实践活动中积累而成的稳定的体育文化，体现在健身、养生、娱乐思维方式、行为方式等体育文化活动的各个方面，并通过社会心理结构及其它物化媒介(如棋盘、武术器械、文献典籍等)得以世代相传。

That our civil rights have no dependence on our religious opinions, any more than our opinions in physics or geometry; that therefore the proscribing any citizen as unworthy the public confidence by laying upon him an incapacity of being called to offices of trust and emolument, unless he profess or renounce this or that religious opinion, is depriving him injuriously of those privileges and advantages to which, in common with his fellow citizens, he has a natural right; that it tends also to corrupt the principles of that very religion it is meant to encourage, by bribing, with a monopoly of worldly honours and emoluments, those who will externally profess and conform to it; that though indeed these are criminals who do not withstand such temptation, yet neither are those innocent who lay the bait in their way

我们世俗的权利并不依赖于我们的宗教见解，正如不依赖于我们在物理学或几何学上的见解一样；所以，如果一个人不声明支持或放弃这个或那个宗教观念，就以不值得公众信任为由将其置于不适合被选举为信任和有薪的职位而排斥他，这有害的剥夺了他的基本人权和利益，而对于这些人权和利益，和他同胞一样，他也拥有自然的权利；同时也趋向于败坏真正的宗教原则，这意味着贿以世间荣誉和报酬的独占权来鼓励那些表面上支持和遵守它的人；这些经不住诱惑的人固然是罪人，然而在他们路上安置诱饵的人也不能说是无罪

Items of Eysenck Personality Questionnaire were translated into Chinese and analysed through biserial correlation with the 4 scales. A slightly modified EPQ in Chinese was given to 370 schoolchildren aged 7—15. Their scores in personality characteristics showed that (1) boys score higher extraversion and psychoticism than girls and girls have higher neuroticism and lie scores than boys,(2) the intercorrelation of PL is negative and very high, that of PE PN EN are all below 0.30 exclusively,...

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
