Some functions in the closure can not be obtained exactly and must be approximated, so the closure is an approximate relation between the correlation functions and the interaction potential 由于闭合方程中有些项不能精确给出,因此我们只能用它来描述关联函数和粒子间相互作用势的近似关系。
Most radar signals are non-stationary signals, but they are cyclostationary signals, namely, the correlation function of radar signals is periodic function of time 大部分的雷达信号都是非平稳信号,但它们都具有循环平稳特性,所谓循环平稳信号是指相关函数为时间的周期函数的一大类非平稳信号。
Chapter 5 is detailed to discuss the produced principle, correlation function and application of gold code . from several aspects, the chapter studied the balanced gold code in-depenth 第五章详细讨论了gold码的产生原理、相关函数及其应用,对性能优越的平衡gold码从不同方面进行了深入的研究。
Especially, the dft approach only needs a second order direct correlation function ( dcf ) of the coexistence bulk fluid as input, and is therefore applicable to the subcritical temperature region 特别是密度泛函近似仅仅需要共存体相流体的二阶直接相关函数作为输入,因而可以应用于超临界与亚临界温度。
Firstly, from the viewpoint of graph theory, we analyzed fitness landscapes, and described the random walk correlation function, then we deduced the equation to compute the correlation length 从图论的角度对遗传算法适应值曲面进行了分析,描述了适应值曲面上的随机游走相关函数,详细推导了相关长度计算公式。
The time-domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ), capturing virtually all of the signal but rejecting most of the noise 对相关函数进行时域滤波,挑选出互相关函数中窄信号自相关函数部分,去掉剩余的大部分噪声能量,得到加窗互相关函数(ccf)。
The hbt radius parameters and the hbt-parameters of single gaussian source and double gaussian source are investigated by using two-pion correlation function in hbt intensity interferometry 摘要利用理想高斯源的两粒子关联函数,对单高斯源和双高斯源的两介子hbt关联效应进行了研究,得出了相应的半径参数和参数。
The theory and the method are validated by the simulational experiments, in which the scattering from random self-affme fractal surface are simulated and the speckle intensity correlation function are calculated 我们通过模拟实验,并以自仿射分形随机表面附近散斑光强的相关函数进行数值计算为例,对该理论和方法进行了验证。
Once obtained the hadronic representation of the correlation function in consideration, qcd sum rule allows one to express the theoretical calculation via hadronic parameters . thus one can derive the interested quantity 只要可以获得关联函数的强子表示,qcd求和规则就可以通过强子参数来表示理论结果,这样就可以得到感兴趣的量。
The paper chooses the velocity measurement as the major content . it puts forward a new method of velocity measurement which applies to correlation function . then the method is realized and testified by hardware and software 论文以速度测量为核心,提出了采用相关算法的测量车速的新方法,并在实验系统硬件、软件上得到实现和验证。
