The article describes the basic working principle and application characteristics of TDI-CCD devices  analyses the composition of TDI-CCD imaging noise  and propose a new method to analyze TDI-CCD imaging noise with statistical probability distribution. In order to estimate the distribution of gray values affect by noise we introduced the concept of skewness and kurtosis. We design an experiment using constant illumination light source  take image with TDI-CCD working at different stage such as stage 16  stage 32  stage 48  stage 64 and stage 96  analyse the characteristics of image noise with the method we proposed  experimental results show that the gray values approximately meet normal distribution in large sample cases. 2011 SPIE.   Comparison of particle size characteristics of the Tertiary 'red clay' and Pleistocene loess in the Chinese Loess Plateau: implications for origin and sources of the 'red clay' 期刊论文  OAI收割 SEDIMENTOLOGY, 2004, 卷号: 51, 期号: 1, 页码: 77-93 作者:  Yang, SL;  Ding, ZL   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/09/26 aeolian deposits  Chinese loess  grain size  kurtosis  red clay  skewness   Comparison of particle size characteristics of the Tertiary 'red clay' and Pleistocene loess in the Chinese Loess Plateau: implications for origin and sources of the 'red clay' 期刊论文  OAI收割 SEDIMENTOLOGY, 2004, 卷号: 51, 期号: 1, 页码: 77-93 作者:  Yang, SL   |  收藏  |  浏览/下载：13/0  |  提交时间：2018/09/26 aeolian deposits  Chinese loess  grain size  kurtosis  red clay  skewness   Testing multinormality based on low-dimensional projection 期刊论文  OAI收割 JOURNAL OF STATISTICAL PLANNING AND INFERENCE, 2000, 卷号: 86, 期号: 1, 页码: 129-141 作者:  Liang, JJ;  Li, RZ;  Fang, HB;  Fang, KT   |  收藏  |  浏览/下载：13/0  |  提交时间：2018/07/30 left-spherical matrix distributions  Mardia's skewness and kurtosis  projection tests  testing multinormality   The P-values of testing for multinormality based on the PP skewness and kurtosis 期刊论文  OAI收割 PROGRESS IN NATURAL SCIENCE, 1996, 卷号: 6, 期号: 3, 页码: 277-283 作者:  Cui, HJ;  Cheng, P   |  收藏  |  浏览/下载：18/0  |  提交时间：2018/07/30 skewness  kurtosis  projection pursuit  P-values  supremum of Gaussian process
