In this study, Chitosan-Poly complex nanoparticles were prepared by template polymerization of acrylic acid in the chitosan solution. The preparation and characterization of CS-PAA nanoparticles including the yields of the nanoparticles, FT-IR spectrum analysis, dynamic light scattering, zeta potential, and morphology of nanoparticles were concentrated in this study. The effects of temperature, weight ratio of CS and PAA, and pH value on the physicochemical properties of nanoparticles were studied.

本研究中，我们以模板聚合法在几丁聚醣（Chitosan， CS）溶液中聚合丙烯酸（Acrylicacid， AA）以制备几丁聚醣－聚丙烯酸复合奈米颗粒并计算其产率，再以傅利叶红外线光谱仪、动态光散射粒径分析仪（Dynamic light scattering， DLS）、表面电位测定仪及穿透式电子显微镜等仪器分析CS－PAA 复合奈米颗粒之性质，以探讨聚合时温度、聚合反应时间、CS 与AA 之重量比，以及介质pH 值对CS－PAA 复合奈米颗粒结构的影响。

Meantime, through great deal of experiments, spark advance angles, ignition dwell angles, start injection width and electrical throttle threshold were optimally controlled. At last, quick response time of hydrogen-fueled engine was realized, speed stability after successful start was controlled. At the same time, backfire, preignition and fire a gun in the start state of hydrogen fueled engine were avoided.

同时通过大量试验调试，对点火提前角、点火闭合时间、喷气正时、电子节气门开度、起动喷气脉宽进行优化控制，使发动机起动响应时间快，起动后转速波动平稳；同时避免了氢燃料发动机起动时易出现的回火、早燃、放炮等异常燃烧现象。
