In statistical analysis of ordinal data, we usually build up linear-by-linear association model and meet a trouble of choice of scores. Graubards et a1 (1987) proposed several methods for score choice in independence test in ordinal 2×κ contingency tables: equally spaced scores, midpoint scores and midrank scores. He also pointed out that the result of independence test may be different for the different choice of scores according to the same association model. Agresti et a1 (1987) treated the score vector in row effects and column effects model for two-way contingency tables as parameters and derived the necessary and sufficient condition of the solution under monotone order restriction by Kuhn- Tucker conditions.

在有序数据的统计分析中，通常要建立线线相关模型，其中得分的选取是一个棘手的问题，Graubard et a1（1987）给出了有序2×κ列联表中独立性检验的几种得分选取方法：等距离得分，中点得分和midrank得分等，同时指出，对于同一个相关模型，独立性的检验会由于得分选取的不同而得到不同的结论，Agresti et al（1987）把二维列联表中的行效应和列效应模型中的得分向量作为参数，在满足递增的序关系情况下，利用Kuhn-Tucker条件给出了解的充要条件。

SOC phenomena does not appears in classical one dimensional sandpile model, but for two or three dimensional model, it does. However, some people did some experiments with rice and find the SOC existing in one dimensional rice pile, it is not fit with the classical sandpile model. Nobody explained this phenomena.

在经典的一维沙堆模型中，沙堆崩塌时并没有出现自组织临界现象，只有在二维以上的沙堆模型中才出现自组织临界现象，然而，后来有人用米粒做实验，发现一维米粒堆中存在自组织临界现象，这与经典的一维沙堆模型相违背，但是却没能对这种现象作出一个较好的解释。

Grey systems theory and method were used here, the article simulated shelf-life entironment at constant temperature 20℃, and constant humidity 90%, texture profile analysis(TPA tests in sarcocarp and core, were carried out and the texture parameters studied chewiness is found to be the diagnostic gene of shelf-life property changes, with grey model GM(1,1) and grey forecasting model based on chewiness were thus established. The veracity and applicabilidy of the grey forecasting model of carrot core were c...

This paper built water quality assessment model based on some basic introduction to PP. It made several conclusions as follows: PP model was stable when sample size was no less than 20. It run much faster when the range of projection vector was constrained between 0 and 1. Accelerated genetic algorithm should be recommended because of its unique advantages. Using scatter diagram of making comparison directly was more convenient than using regression model.

该文在介绍该模型基本计算步骤的基础上，经建模分析，得出：各评价等级取值范围内样本个数不小于20即可具有较好的稳定性，投影向量分量的取值范围为[0，1]时更有利于提高计算速度，选用加速遗传算法寻优时间更短，使用图解法或直接比较法更为方便和快捷。
