1. Kinematics of Mechanism: the study of motion without regard to forces That is about motion of the components and the basic geometry of the mechanism, and is not concerned with the forces which cause or affect the motion all the components of the mechanism are, in general considered rigid member 2. Kinetics or Dynamics of Mechanisms: the study of forces on the system in motion

基因表达 DNA分子将所承载的遗传信息通过密码 子—反密码子系统，转变成蛋白质分子从而执 行各种生理生化功能，这个从DNA到蛋白质的 过程称为基因表达调控。基因调控是现阶段分 子生物学研究的中心课题

一、国际贸易(international trade)是指国际范围内国家与国家之间进行的商品、劳务和技术交换活动。国际贸易亦称世界贸易(worldtrade)。 二、对外贸易(foreign trade)是指一个国家与其它国家进行的商品、劳务和技术交换活动。这种贸易由进口和出口两个部分组成。 三、国际贸易与对外贸易在内容上并无本质不同，区别在于考察的角度不同

一般均衡理论是边际学派以生产可能性曲线和消费无差异曲线作 为分析手段，进一步论证了国际贸易能够提高贸易双方的福利水 平
