次波动 meaning in Chinese
secondary undulation
Examples
- The death rate of individuals in beiwenquan population is fairly higher initially and stable afterwards , while after 10 years , the death rate has appeared several waves , and then achieved the biggest physiological life span at 13 years with the death rate sharply up
北温泉种群的死亡率在幼苗时比较高，以后比较稳定，到10龄时开始下降，以后出现几次波动，个体在13龄时达到种群的最大生理寿命，死亡率急剧升高并最终消失。 - ( 2 ) based on the model of synthetic jet actuators , the flow field of synthetic jet is simulated by 2d and 3d numerical methods . and finds some significative results by simulating and analyzing . first , the development and evolution of the synthetic jet can be divided into two distinct domains , which compares favorably with the measured data in tests
通过分析的得到了以下结论：一、合成射流在向下游传播过程中，在出口附近流动速度经过一个较大峰值后快速下降，尔后流动速度经过几次波动后缓慢下降，这与实验观测到的合成射流的演变分为两个明显不同的区域相吻合。 - Beyond the usual method , the one dimensional equation was expressed in the form of ( the equation is abbreviated ) , which then was introduced by middle varible ( the equation is abbreviated ) , so that the same solution of initial value problem by the characteristic curve method of the first order equations ( the equation is abbreviated ) and ( the equation is abbreviated ) was abtained
摘要对一维非齐次波动方程的始值问题在传统的叠加原理、达朗贝尔公式、齐次化原理的方法之外，完全用特征线方法，先将方程表示为(方程式略)的形式，进而引入中间变量(方程式略) ，得以用一阶方程(方程式略)的特征线方法，推导出维该始植问题的与传统方法相同的解。
