Results Single factor logistic regression showed that the risk factors to myopia were the distance between eyes and book when reading, reading on the bus, hours spend on doing homework every night, exceeding 40 minutes once reading or doing homework, eyestrain and favorite taste. The result of further multiple logistic regression was that distance between eyes and hook when reading, reading on the bus, eyestrain and favorite taste had statistical difference (P.05) to the model.

结果 单因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、每晚做作业时间、一次看书写作业持续时间超过40min、眼睛酸累和最喜欢咸味是小学生近视发生的危险因素；进一步多因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、眼睛酸累和最喜欢咸味对模型的作用有统计学意义（P值均＜0.05）。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.

本文以霍山县作为皖西大别山区的典型区域，主要研究了以下内容：(1)从介绍霍山县土壤侵蚀状况以及所造成的危害入手，全面分析了导致当地土壤侵蚀发生的原因，并结合当地采取的水土保持相关措施，阐述了当地水土保持工作的症结所在；(2)结合上土市水土保持试验站多年实测资料和2005年实验资料，应用BP神经网络理论，建立了次降雨土壤侵蚀量与次降雨量、最大30min雨强、径流系数、植被覆盖度等因子之间关系的模型，并通过BP神经网络的预测模型与一次回归模型、二次回归模型、CSLE模型之间的对比分析，说明了建立的BP神经网络模型在土壤侵蚀预测可以取得较回归模型和CSLE模型更高的精度，也说明了BP神经网络理论在土壤侵蚀预报中具有一定的适用性。

Based on data of per mu yield of spring-sown soybean and of cli-mate in Hengyang from 1975 to 1981,the tendency yields are estimatedfirst by the method of orthogonal polynomial regression,and then by theFisher's integral regression equation for the out-tendency yields andclimatic factors in this city.

依据1975～1981年衡阳市的气象资料和春大豆亩产量资料，首先用正交多项式回归方法估计了趋势产量，然后用费希尔积分回归模式和逐步回归方法计算出了该市气候因子和离趋势产量间的积分回归公式。

Also, the establishment of logistic regression model proves that the choice of stock delivery valuation methods doesn't vary greatly by political affairs and cost of contract, while the establishment of multiple linear regression model bears out that there is a statistics significan ce between accounting evaluation, accounting profession judgment from listed companies' non-circulating assets value depreciation and reflux and the scale of major business income and the relation of high and low ratio of debt to equity. Yet, there is no statistic significance between the relationship of the publication of interest encouraging plan and company establishment date.

在此基础上，本文抽取了实施新会计准则体系之前2005年我国上市公司样本，通过建立有序分组的线性趋势检验模型研究证实，以0.05为显著水平，我国上市公司存货收发频繁程度与发出存货计价方法简化程度之间，并不显著存在一般认为应有的线性关系，排除了发出存货计价方法选择这一混杂因素的影响；进而，通过建立logistic回归模型证实，发出存货计价方法的选择也并不显著受政治和契约成本的影响；通过建立多元线性回归模型证实，上市公司对非流动资产减值的会计职业判断，与其主营业务收入的规模和负债权益比率的高低之间的关系有统计学意义，与是否公布股权激励计划和公司成立时间之间的关系没有统计学意义。

Formly, HDR casts classification problems and regression problems into a unified regression problem. Clustering is performed in both output space and input space at each internal node, termed "doubly clustered" and discriminants in the input space are automatically derived from the clusters in the input space. A hierarchical probability distribution model is applied to the resulting discriminating subspace at each internal node.

在图像的分类和检索中，以前的层次判别回归方法把分类和回归统一成回归问题，在每个内部节点进行输入和输出空间的双聚类，输入空间的分类子空间可以自动从聚类中获得，再用层次概率分布模型计算判别子空间，这样就构成了输入空间由粗到精的概率分布，可以准确而且快速地实现高维数据的检索。
