能流密度 meaning in Chinese
energy flux density
energy-flux density
Examples
- Influence of energy flow density of ion current on growth of diamond - like carbon thin films
离子能流密度对类金刚石薄膜成膜的影响 - In fact , the traditional definition of the light intensity is only suitable to the paraxial - scalar diffraction light field , not to the non - paraxial scalar diffraction light field and vector diffraction light field
考虑到光场能流密度的矢量特性，这种方法具有很大的局限性，只适用于描述傍轴标量光场，而不适用于对非傍轴标量光场的描述。 - Considering the vectorial property of the time - average energy flow density , a new extensive definition of the light intensity has been proposed . it is expressed as the time average of the amount of energy which crosses in a unit time and a unit area , so it can be applied to measure quantity of the light intensity at any curved surface
对于非傍轴标量光场能量传输规律的描述则必须考虑其能流密度的矢量特性，应当采用光强的精确定义? ?单位时间单位面积上所流过能量的时间平均值来精确地描述某一横截面上的能流，这也与光强的实际测量值是一致的。 - Finally , the results are compared with periodic and random chains . then we studied acoustic wave propagation in 1d quasiperiodic and aperiodic systems by means of he transfer matrix . transmission rate , reflection rate , energy flow , logarithmic energy flow , energy density and lyapunov exponent are computed numerically , and compared with periodic and random system
其次研究了声波在几种一维准周期和非周期系统中的传播，通过转移矩阵的方法，数值地得到了系统的传播系数t _ n 、反射系数r _ n 、能流密度j _ n ，能量密度e _ n和lyapunov指数，给出了以上各量与传播长度n以及频率之间的关系，同时发现能流及能量密度都具有分形结构，并与周期和随机系统的结果作了比较。 - Firstly , acoustic waves propagation in id quasi - periodic system is studied by means of the transfer matrix method . the transmission rate , reflection rate , energy flow , logarithmic energy flow , energy density and lyapunov exponent are obtained numerically . we explain all these parameters " relations with frequency and the size of system , and compare these p arameters with those o f periodic system . we find that these parameters are fractal in this quasi - period system
通过转移矩阵的方法，数值地得到了系统的传播系数t _ n 、反射系数r _ n ，能流密度j _ n 、能量密度e _ n 、李雅谱诺大指数_ n ，给出了以上各量与系统大小n以及频率之间的关系，发现这些量存在着与周期系统不同的准周期性质，其能量会出现局域化现象，能流以及能量密度都具有分形结构，给出了相应的理论解释。
