As there are only six parents in the diallel crossing. and one cross combination for genetic effect analyzing, and the datum from the number of regenerating didn't submit to the normal distribution formula even when they were transferred, there may be some aberrancy in the result of this character. Therefore, more experiments and larger samples are needful further to conform, improve or correct this research results later.
7本研究双列分析的亲本仅为6个,世代的基因效应分析也仅只有1个组合,可能导致统计分析结果偏颇,还由于性状胚性愈伤组织绿苗再生数资料经转换后仍不能遵从正态分布,也会使得该性状的分析结果可能有偏差,今后需要用更多的试验和抽取更大的样本进行分析研究,进一步证实、完善或纠正本试验结果。

This method was applied to the dimensionality reduction of multidimensional time series via projection pursuit technique for fuzzy clustering. According to the results of the classification and the extraction of fuzzy rules through best value projection, three types of fuzzy membership function were generated using trapezoid distribution method.

The conclusion of paper conclude two parts:1. the hand of the Geological Character(1) Shandong conclude six research plots: the hard magma rock plot, the hard sediment rock plot, the plain and riverway alluvium-proluvial plot, the alluvium strand plain plot, the bajada plot and the mountain front sedentary plot.(2) The span of physical and mechanical index is effected by the character of stratum and geological zone. The normal value of physical and mechanical index is not even. The coefficient of variation of synthesis is bigger than the coefficient of laminate. The coefficient of variation is divided into three level: dry density

Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.
同时,由于Poisson分布的特性,我们知道不存在其参数区间长度小于0.5的置信区间,基于这些情况,我们主要展开了以下两个方面的研究:一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间,Wald置信区间,Bayes置信区间等进行分析比较,发现了一些缺陷,针对这些缺陷,我们进行适当的修正,并得到几种性质较好的置信区间如:修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度,我们提出了一种渐近的两阶段区间估计程序,并利用数值计算的方法,在各种置信系数与区间长度限定下,算出了最优的第一阶段观测次数,大量数据表明,本文考虑的方法性态良好,具有应用价值。

Using Spatial Lag Model and Spatial Error Model, a spatial econometric analysis on institutional spillover effect of marketization degree in China's provinces and the effect on regional economic growth is performed. The results of spatial analysis show that after nearly 30 years' development of China's provincial economies reform and opening, the spatial association becomes closer while geographical clustering obviously intensifies, and the institutional spillover effect among the provinces becomes confessedly.

At first, the wind tunnel test and test data process of this study are introduced in detail. A method to calculate expected extreme values of time series with a long time interval is then proposed with its sub-sections based on the classical Gumbel theory for extreme values and the independence of observed extreme values. At last, the extreme values of the wind pressure coefficients of the present wind tunnel test are calculated with the proposed method and methods used widely at present, such as peak factor method, improved peak factor method and Sadek-Simiu method.
