\...every synthetic chemist is well advised to follow this fascinating field with appropriate attention.\

一． 热力学 Thermodynamics与反应方向 二． 动力学 Kinetics与反应活性、选择性 三． 反应机制 Reaction Mechanism 四． 反应活泼中间体 Active Intermediates 五． 有机反应机制的研究方法

一、有机化学的定义 有机化学( organic chemistry)是研究有机化合物 的来源、制备、结构、性能、应用以及有关理论和方法 学的科学。 常见有机化合物:粮食、油脂、纤维、石油、橡胶、 糖、药材等

The first three types of control devices we consider--gravity settlers, cyclone separators, and electrostatic precipitators--all function by driving the particles to a solid wall, where they adhere to each other to form agglomerates that can be removed from the collection device and disposed of
