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.

The result shows that: with the expansion of teacher education space, the reform and development of Chinese teacher education is much closer or equal to that of the international teacher education. The transitional stage and education reform in China puts forward a new demand for P. E. talents. The innovation as to education object, specification and curriculum arrangement raised in P. E. Curriculum Arrangement for Chinese Universities with four-year Program published in 2003 meets such a demand, and narrows the gap of education development in high P. E. academy between China and foreign countries. P. E. teachers abroad are usually cultivated by comprehensive universities, the cultivating objectives are verified, and generalists adapted to social development are emphasized. Cultivating mode abroad are various, with "open-type" or "non-directional type" as the main mode, and 4-year program, 5-year program, and 3-year program serve as the main form of education system. Curriculum arrangement abroad stresses general education, with foundationalization, normalization, objectification, optionalization, miniaturization, internationalization and syntheticalization as its characteristics and it employs credit system. The close-typed cultivating mode of P. E. academies in China should be gradually transformed into open-type or multi-type, cultivating generalists instead of specialists, and further constructing a new one with several cultivating types co-existing. Orientation of P.E. teachers in China should follow standard principle, coordination principle, experience principle and resource principle. To improve P.E teacher education in China, the following measures can be taken: relevant laws and regulations should be made for orientation; P.E teachers" training organization should be encouraged to participate in orientation; extension and connotation of P.E. teacher education should be expanded; resources should be optimize; systematic P.E. teachers" orientations should be organized;"Life P.E. Teacher Qualification "should be changed; useful-life should be set for P. E. teacher qualification; P.E. teacher qualification should be regularly authenticated; On-job training of P. E. teachers abroad tends to be systematic, but in China P.E. teachers" on-job training and prevocational training are separated; therefore measures must be taken to change this circumstance and thus speed up the systematic process. Factors concerning constructing a new system of P. E teachers are the following: reconstructing resources, making P.E. teachers" cultivation, orientation and training systematic, establishing a mechanism for encouragement and punishment, making school-based training and college training systematic, and setting up a mechanism combining directional training with non-directional training.

Chicken IL-15(ChIL-15), Which was discovered in 2001, plays a main role in activating NK cells and CD8+ memory T cells, and may therefore have potential as a vaccine adjuvant.According to published ChIL-15 gene sequence, a pair of primers were designed and synthesized to clone ChIL-15 cDNA from ConA-activated chicken splenocytes by RT-PCR. Recombinant plasmid pUC19ChIL-15 carrying the ChIL-15 gene was constructed. The gene encoding mature ChIL-15 (mChIL-15) was amplified from pUC19ChIL-15 by PCR and cloned into pMD 18-T vector. After digested with Kpn I /Pst I , the mChIL-15 gene was subcloned into prokaryotic expression vector pPRoEX橦Ta and transformed into E.coli DH5a .The transformant was induced by IPTG, and the recombinant ChIL-15(rChIL-15) was expressed as a fusion protein with a histidine hexamer tag at the N-terminal end of the protein. Following expression, the protein was purified by ProBond?Nickel-Chelating Resin. The uninduced and induced protein lysates and the purified protein were separated by SDS-PAGE and transferred onto nitrocellulose membrane to identify rChIL-15 by Western blot. The rChIL-15 was used to immune the guinea pig to obtain rChIL-15 polyclonal antibody.

同时最近几年，Banfiled又提出了一种新的晶体生长机制也能形成单晶结构，oriented attachment，多个取向不一致的单晶纳米颗，通过粒子的旋转，使得晶格取向一致，向后通过定向附着生长使这些小单晶生长成为一个大单晶，当然定向附着的过程出难免会出现一些位错和缺陷，这种生长机理形成的单晶的特点同Ostwald ripening不同，OR形成的单晶大多是规则的，给材料本身晶体结构相关，而OA形成的单晶结构在形貌上则没有限制，任何形状和结构的单晶材料都能通过此机理形成。

The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.

脱颗中的组胺等物质会引起毛细血管壁通透性的增加，进而引起组织液流动速度的增加和肥大细胞表面的切应力加大，这样会进一步促进肥大细胞的激活，从而释放更多的活性物质，这些物质一部分被静脉端毛细血管吸收进入血液，另一部分则随着组织液的定向流动向远处，并进一步刺激远处的毛细血管和肥大细胞，而组织液的定向流动途径和传统的经络线走向基本吻合，在宏观上就构成了循经感传现象。
