特别是当观测数据出现在转移概率分布的尾部或似然函数同转移概率分布相比过于集中时，一般的粒子滤波器可能失效。

This method can be presented as a theory tool for time sires modeling based on high order cimilant in fault diagnosis.

由于该方法是基于高阶累计量的，没有用自相关函数，该方法可以对非高斯信号建模，抑制高斯有色观测噪声，为基于高阶累计量时序建模的机械故障诊断提供了新的的理论工具。

Based on curve fitting,deformation observation data is processed and deformation tendency function is made out.

本文以爱尔朗分布为基础，将高速公路上车辆分为队状跟车和非跟车两种类型交通流，用大量实地观测数据检验分布的特性，推导出非跟车流车头间隔的概率分布函数和仿真用的两种交通流的随机变量公式。

Starting with the zenith, a series of star fields at different altitude are observed by a telescope with larger field of view, the derivatives of various orders are calculated at different zenith distances, and finally the observational atmospheric refraction can be obtained by numerical integration.

利用一台较大视场的望远镜从天顶开始，在不同高度上对星空作一系列观测，计算不同天顶距处大气折射函数的各阶导数，最后经数值积分可给出大气折射实测值。

Using LMS and LS as the merit function separately,in this paper we take the multi-stage inversion of the SAIL model as an example to inverse the ground parameter.

本文以遥感BRDF物理模型——SAIL模型为例，使用模拟数据与真实地面观测数据，构建LMS与LS两种代价函数，分阶段地进行地表参数的反演方法研究。

We find that model LBGs can have the same Two Point Correlation Funtion over the range of observable separations even though the cosmology and/or galaxy formation model are different. Moreover, with similar galaxy formation models, different cosmologies can result in both the same TPCF and the same PVD.

进而发现：(1)即使宇宙学和星系形成模型均不同，模型Lyman Break星系在可观测的尺度上也可以表现出一样的两点相关函数；(2)另外，不同的宇宙学模型可以预言相同的TPCF和PVD；(3)然而，不同的星系形成模型即使保持TPCF一样，也将预言截然不同的PVD。

With the in-depth observation and research, the effects of dipping boundaries and anisotropic media on receiver functions have attracted to geophysicists′ attention.

近年来，随着观测和研究的不断深入，倾斜界面和各向异性介质对接收函数的影响也逐渐引起人们的重视。

In addition, since the channel frequency response is usually oversampled by the pilot sub-carriers, the channel power will be concentrated to a relatively small number of samples in the effective channel impulse response vector.

这种情况下，如果在进行基于DFT的内插之前，我们不用一个窗函数对观测到的信道频率响应向量进行加窗处理，则内插后，由能量泄漏而引起的混叠现象将导致信道估计的错误平底。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。
