Because of its easily calculating and its accurately description parametric method has became mainstream in study field, polynomial hazard function distribution model was a large class of parametric models, when the dates are not readily handled by one of the common models such as exponential distribution or Weibull distribution, polynomial hazard function model always be used to provide adequate fits of the dates.

随着该学科的发展，大量参数、非参数方法相继提出，特别是生存分析的参数方法，以其处理简便、描述准确成为生存分析研究的主流方向。多项式危险函数模型是参数模型中的一大类，当一批数据不能用熟知的一些分布，诸如Weibull分布、对数正态分布进行很好的描述时，常常使用多项式危险函数模型。

The papes utilizer Parzen's kernel estimate theory which was used in estimating the function ofprobability intensity and Chen Xiru's results in the field to strictly prove the following fact.Whenusing non-completeness knowledge sample W to find the law which W would be kept to,thefrom:is closer to real pthan the estimate of rectangular diagram.

二项分布分析显示，血压盐敏感性和冷加压试验阳性者在同胞中的分布具有聚集性，表明血压盐敏感性和冷加压试验阳性可能主要由遗传基础决定，而非生活环境影响。

The generating reason,response characteristic and distributing rule of remaining oil was deeply studied aiming at water-flooded continental reservoir with characteristic of intense heterogeneity,high water-cut,low recovery efficiency,complex distributing rule of mobile remaining oil,intergrowth of major and untabulated formation . At the same time,a systemic method of evaluation and predicating remaining oil and pressure was put forward basing on the theory of development geology,seepage flow mechanics,fluid mechanics which resolved the hard technologic problem of predicting remaining oil and pressure.

本文针对陆相注水开发油藏具有非均质性强、含水率高、原油采收率低、可采剩余油分布复杂、主力产层和表外产层同时存在等特点，深入研究了剩余油的形成机理、响应特征和分布规律，应用开发地质学、渗流力学、流体力学和地质统计学理论，将静态地质数据和动态开发数据相结合，综合现有的与剩余油及压力分布有关的所有资料，提出了一套系统的评价和预测剩余油及压力的方法，较好地解决了目前剩余油与压力评价和预测中的技术难题。

This method selects two parameters, energy and variance, as the characteristic parameter of trolley track, and successfully in extracts the feature frequency belt of trolley track vibration. Furthermore, this technology is applied to practical engineering programs and has good veracity and reliability.2. According to the research of this thesis on the trolley tracks\' present data, the status classification of trolley track with normal distribution is presented. This method divides trolley tracks\' situations into five parts and perfects the classifying method of trolley tracks\' mechanical situation.
