density fluctuations meaning in Chinese
密度变化
密度波动
Examples
- We currently have a coherent model that tracks the growth of subtle density fluctuations laid down in the early universe to the present richness of the night sky
现在我们拥有一致的理论模型，能够描述早期宇宙密度的细微起伏，一路上是如何成长，而成为现在夜空中的丰富结构。 - We employ largest lyapunov exponent to explore the relation between the chaos and phase transition . then , we study the mechanic ( spinodal ) instability of these nuclear systems with the density fluctuation
我们通过改变基态核的温度(激发能) ，来研究核体系随温度(激发能)的改变而发生的相变。 - And the incompressible navier - stokes equations are exactly derived from this incompressible lbgk model , thus the compressible effect due to the density fluctuation is theoretically eliminated
其中密度保持为常数，使得从格子bgk方程能够导出宏观不可压ns方程，理论上消除了因密度变化导致的压缩误差。 - Cosmologists assume that our universe , with an almost uniform distribution of matter and initial density fluctuations of one part in 100 , 000 , is a fairly typical one ( at least among those that contain observers )
宇宙学家假设，我们的宇宙是一个相当典型的宇宙，具有几乎均匀的物质分布，与十万分之一的初始密度涨落。 - Making use of the wigner transform of the one - body density matrix , the coherent density fluctuation model ( cdfm ) is introduced into semiclassical distorted wave ( scdw ) model . the new model is applied to the analyses of multistep direct processes of ( p , p ' x ) reactions to continuum
本文利用单体密度矩阵的wigner变换，将相干密度涨落模型( cdfm )引入半经典扭曲波( scdw )模型，并将新的scdw模型应用于分析预平衡反应( p ， p ' x )中散射到连续态的多步直接过程。
