As we have learned, had arrived to make sure activated carbon puts in smoothly 25 days among filter, total fleet of Heilongjiang province armed police is close 1000 officers and soldiers from 24 days 17 when to 25 days of before dawn 4 when, day and night endlessly, many tons of 1000 in crossing 16 filter anthracitic filter expects all Qing Dynasty goes out. 10 when make 30 minutes, the reporter sees, as a result of excessive overworked, a lot of people in them were leaning on baluster to be asleep.

To give the definition of the mass concrete and to concrete\'s cracks together with practical meanings of control ,and give a brief review on the research in the field at home and abroad, at last, methods to control temperature crack of the mass concrete from several aspects such as design measures,concrets material, construction schedules.etc are summed up; To explain the physical mechanics of the concrete and computing methods-Difference Method and Finite Element Method, and illustrate the application of their specific methods repectively;Several temperature factors that can influence the temperature stress of mass concrete baseplate are analyzed. The influence degree of temperature factor can be got through the ANSYS simulation computation the control of temperature can control the temperature stress, consequently control the temperature crack of mass concert baseplate; through the influence of the crack resistance ability of mass concrete baseplate which takes the reinforcement as a part is analyzed. By ANSYS simulation, the best suited volume ratio of reinforcement is found out, at same time the layout of reinforcement with the same volume ratio can also affect the resistance ability of mass concrete baseplate. Sum up of above analysis, anti-crack function of steel bar in early mass concrete baseplate is obvious, so it\'s necessary to consider beneficial effect of construction steel bar in research of temperature control on mass concrete baseplate.

本文先容了大体积混凝土及混凝土裂缝的基本概念，对国内外在这个领域里的研究现状作了扼要叙述，并从结构设计、混凝土材质、施工措施等方面总结了大体积混凝土温度裂缝控制的方法及防止措施；阐述了混凝土的基本物理力学性能，总结了大体积混凝土温度计算的方法——差分法和有限元法，并分别举例说明其具体应用的方法；分析了影响大体积混凝土底板温度应力的几种温度因素，利用ANSYS模拟计算，得出了每种因素的影响程度，通过分析提出了在这几种温度影响因素下如何通过控制温度以达到控制温度应力从而来控制裂缝的具体建议；针对大体积混凝土基础底板中配筋的不同对混凝土底板抗裂能力的影响不同，利用ANSYS进行模拟分析，得出底板中最合适的体积配筋率，同时分析了在相同体积配筋率下钢筋的具体布置对大体积混凝土基础底板抗裂能力的影响，分析表明，配置钢筋对混凝土结构的开裂阻止作用明显，在研究大体积混凝土温度裂缝题目时，要考虑钢筋在其中的有利作用。

论文主体部分共分四章：第一章"《彼得堡》在别雷创作发展中的地位"，主要描述别雷的整个创作历程，并以此为背景考察别雷的主要创作的特点，指出《彼得堡》在他全部创作中的巅峰地位，并分析《彼得堡》在艺术构思上对传统的继承和创新。

A practical problem coming from field investigation is studied in this paper by using the bifurcate model presented by K.

Ruina单变量摩擦定律基础上建立的岩体系统分岔模型，分析了在实践中遇到的问题，结果表明边坡岩体系统在演化过程中会出现三个奇点类型，即焦点、结点及鞍点。

A sequenced method in consideration of the sample range was proposed to rationally array classifiers of a support vector machine with binary tree architecture. A sample distribution radius and a sample distribution distance were introduced to estimate sample range of all classes in high-dimension characteristic space. The classes with bigger sample range were classified earlier in the higher nodal point of the binary tree architecture, and were given wider classificatory areas in the characteristic space.

考虑到样本的分布情况对分类器推广能力具有较大影响，提出一种次序二叉树支持向量机多类算法，采用样本分布半径和样本分布距离估算各个类别的样本在高维特征空间中的分布情况，把分布半径较大的类别或者分布距离较大的类别较早地分出来，并且在特征空间中给其划分较大的分类区域。

In the argument between invention and discovery on patent of biotechnology .I ,firstly, take back look at the definition of invention and discovery in practice of patent of biotechnology in western countries . then ,analyse the possibility of putting the result of basic bioresearch into patent .Finally ,draw a conclusion :we should focus on the achievement of research on natural material and gene invention should be patented as long as the material and gene which have been separated and purified have real value .

关于生物技术专利中的发明与发现之争，本文首先回顾了西方发达国家在生物技术专利实践中对发明与发现的界定，接着分析了生物技术基础研究成果的可专利性，最后得出结论，我们应淡化发明与发现之分，着重于"三性"审查，即只要天然物质和基因被分离和纯化以后具有工业实用性，就应该给天然物质和基因发明等基础研究成果授予专利。
