As EFCI switch is considered, flaw of existing two-phase analysis model is pointed out, and four-phase single bottleneck simple model is advanced. With this model, the effect caused by typical control parameters is studied and analyzed. As more indepth research, the double bottleneck complex model is further brought forward.

In the JTB series Roots blower developed by Chongqing Chuangu electromechanical equipment Co., Ltd, the single oil base is changed the dual oil base, this avoids to burning bearing by lubrication no good. The check valve and T-joint are designed into one, this simplifies the installation process and avoids to some troubles. The more important is that all parts of the rotor are the overall, this greatly increased the stiffness and received by the market.

重庆川鼓公司研发设计开发出JTB系列罗茨风机，将单油箱改变成双油箱，从而避免了因润滑加不及时或不到位而烧轴承的现象；将单向阀与T型接口设计成一体，简化了安装工序，克服由此引发的故障；更重要的是全部转子部件采用整体结构，大大提高了刚度，因此受到市场欢迎。

In this dissertation, two derivatives of aniline containing polyoxyethylene substituent m-phenylene diamino formyl alkylenediamine poly acetate and poly-3-aminobenzoate were designed and synthesized. And then, comb-shaped polyaniline grafted by PEO were prepared by chemical oxidation copolymerization. The structure of copolymers were characterized by FTIR, ultraviolet-visible spectrum, elemental analysis and TEM etc..
