参量变化 meaning in English
parametric variation
Examples
- Kinetics is a subject in which the rate of a reaction is studied as certain parameters are varied .
动力学是研究反应速度随某些参量变化的一门学科。 - On the basis of information acquisition software , multi - method in data acquisition is also designed . but original data ca n ' t reflect parameter ' s variety , so software pretreatment the original data , and save data by sql server 2000
而采集的原始数据不能直接反映结构的参量变化，因此对测量的原始数据进行了预处理，并采用sqlserver2000数据库系统对自动采集过程中的数据进行存储。 - And the effect of the work order of the two propellant units to the performance of the trajectory and the matching conditions to obtain the theoretical optimum trajectory is discussed too . according to the ballistic speciality of a hybrid base - bleed - rocket extended - range projectile during base - bleed and rocket work , its physical parameter is non - constant , such as its mass position of mass centre polar and equatorial moment of inertia . after a mulriple ballistic model of constant physical parameter is established , a mulriple ballistic model of continuous and non - continuous physical parameter is educed and the program is compiled , the theoretical tool is constructed to study othe other pivotal technology of a hybrid base - bleed - rocket extended - range projectile
