答案和解析
dynamics的意思比kinetics要广很多,以下是dynamics的释义,只有第一义项下两者可以通用.
=============
1)(used with a sing.verb)The branch of mechanics that is concerned with the effects of forces on the motion of a body or system of bodies,especially of forces that do not originate within the system itself.Also called kinetics
(与单数动词连用)动力学:机械学的分支,有关各种力量在运动体或运动体系统上的作用,尤指非系统本身产生的力也作 kinetics
2)(used with a pl.verb)The forces and motions that characterize a system:
(与复数动词连用)动态:可代表这种系统的各种力或其运动:
The dynamics of ocean waves are complex.
海浪的运动是复杂的
3)(used with a pl.verb)The social,intellectual,or moral forces that produce activity and change in a given sphere:
(与复数动词连用)社会力量:社会的、理智的或道德的力量,它在一定范围内产生运动与变化:
The dynamics of international trade have influenced our business decisions on this matter.
国际贸易的动态影响了我们对此所作的商务决定
4)(used with a pl.verb)Variation in force or intensity,especially in musical sound:
(与复数动词连用)力度变化:力度上的变化,尤指音乐中:
“The conductor tended to overpower her with aggressive dynamics”(Thor Eckert,Jr.)
“指挥打算用过分的力度变化压倒她”(小索尔·埃卡特)

在语言学中,kinetics有一个意思是dynamics没有的,那就是“体态学”,主要研究的是肢体语言.
