unconstant造句

• According to the principle of mutual transformation between potential energy and kinetic energy , the vertically falling law of power law fluid by the action of unconstant static pressure and the relation between rheological parameter and time were studied , thus providing a theoretical basis for calculating the rheological parameters of fluid in funnel viscometer
  根据位能与动能的变化关系，作者研究了在非恒定静压作用下幂律流体垂直下落的规律及流变参数与时间的关系，从而为计算漏斗粘度计中流体的流变参数提供了理论依据。
