惠子语带玄机的说：「吹萧笛的声音响亮，吹剑环那个小孔的声音就低多了，它只有那么一丝丝微弱的响声；尧舜被一般人称为圣人，可是比起戴晋人的一席话，那尧舜也不过是那吹剑环者，其主张是微不足道的。

The simulation of the vector control system for rotor flux orientation is studied in this paper. The modeling and simulation of the vector control system of speed and flux closed-loop with the torque inside loop are completed by applying electrical principles and the toolbox of Simulink and Power System in the Matlab software. The paper mainly introduces the modeling of the speed adjustment system and the setting of parameters of the controller. The obtained results of the simulation are close to actual situation, which proves the correctness of the modeling.

In this paper, active groups terminated silicane was used to react with the hydroxyls of bisphenol A epoxy resins, that introduced organic silicon without consuming epoxy groups. This modifying process improved the combining degree of the cured resin, so both the toughness and the other characters (as strength, thermal resistance) were all could be improved.

为此本论文采用国内外文献中尚未见报道的、带活性基团的有机硅来改性双酚A型环氧树脂，通过端基基团与环氧链上的羟基反应生成大键能的Si-O键的方式来引进有机硅，改性过程中不仅不消耗环氧基，并且还提高了树脂固化物的交联密度，所以既能增韧树脂，又能提高其耐热、耐冲击等各项性能。
