To achieve high-performance PMSM position servo system, advanced control scheme, which is static precision, transient responses and self-adaptation and anti-disturbances, is needed in practice. Based on the analysis on the features and control principles of PMSM, this thesis established its math model using id=0 vector control method. Three close loops control system, which includes current loop, velocity loop and position loop, was built up. For position loop, the main feedback loop, we chose a new adapted-fuzzy CMAC intelligent controller, which includes self-learn ability of neural net and quick response merit of fuzzy controller. Finally, the author simulates PMSM position servo system by the simulink of matlab, an advanced computer simulation tool.

本文对PMSM的控制机理和特性作了较为深入的分析；建立了PMSM的数学模型，并采用了id=0的矢量控制策略；对控制系统组成及控制方式作了分析和比较，在此基础上建立了电流环、速度环和位置环的三闭环控制系统，对作为反馈主回路的位置环采用了模糊CMAC神经网络控制方法，该方法兼具模糊控制器的快速性和神经网络的自学习能力；构建了针对PMSM位置伺服系统的模糊CMAC控制器结构及其相应的算法；利用先进的计算机仿真工具（Matlab下的Simulink）对所提出的控制策略进行了数字仿真和分析；仿真和实验结果表明本文所提出的控制策略对PMSM位置伺服系统进行控制具有良好的鲁棒性能和快速性。

A trigger tab (104) engages the trigger arm when the seat is returned from the forwardly extended position to the full rearward position to release the cam plate to the non-actuated position and allow the locking mechanism to return to the locked position interlocking the upper and lower tracks and preventin g further sliding movement therebetween.

当座椅组件从前伸位置返回到最靠后位置时，一个触发片(104)与触发臂接合，从而将凸轮盘松开并使之回到非致动位置，并且使锁止机构回到联锁上下滑轨并阻止两者间的进一步滑动的闭锁位置。

The yields were better when DHPCE with nitro group in meta or ortho position of the benzene ring were hydrolyzed in basic conditions, while the hydrogenolysis and acidic reactions gave very poor yields.

当苯环的间位和对位存在硝基，碱性水解时，在二氢吡啶环的3位引入氯乙醇的酯能得到较好的收率；酸性水解和氢解法则不宜用来合成ADHPA。

We described that the nitro group is a stronger electron withdrawing and meta activating characters than the imide group, the amino and hydroxy are both electron donating groups and had ortho, para activating characters. The methyl group might have a steric hindrance effect in this reaction. Our results indicated that methyl group at the ortho position of the amino group on the benzene ring, the steric hindrance effect became stronger.

另一方面，由产率上的结果来看，可以得知硝基为强力的拉电子基团，会减少邻位和对位胺基的电子密度比间位多；而氢氧基与胺基是供电子基团，会增加邻位和对位胺基的电子密度比间位多；甲基取代对反应则只有立体障碍的影响，而且与反应的氨基成邻位存在下影响最大。

Meta analysis shows, only sex of 3 heredity much condition and male not Yo is remarkable and relevant, namely AZFc division share is short of break, androgen accepts put oneself in another's position genen length and methylene 4 hydrogen folic acid is reductive enzymatic gene much condition.

Meta分析显示，仅有3个遗传多态性和男性不育显著相关，即AZFc区部分缺失、雄激素受体基因n长度和亚甲基四氢叶酸还原酶基因多态性。

Finally, I adopted a meta-position to reflect the meaning of the situation, deconstructed and reframed the value system and then formed the practical knowledge.

这三年走下来，在与新台湾之子的互动经验中，冲击我对原本小学教育应有的视框，解构再建构，型塑我许多的实践知识与理念。

The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。
