Huang and Lin proposed the weak solution concept for Backward Stochastic Differential Equation This paper based on the predecessor's work , gives the weak solution concept for Backward Stochastic Differential Equation with continuous martingale,uses the Girsanov transformation, obtains its weak solution of the existence of a necessary and sufficient conditions, and on this basis obtains its weak solution of the existence of sufficient conditions,these sufficient conditions weakened the drifting coefficient which requested in the existence uniqueness of strong solution to satisfy the Lipschitz condition the request.

本文在前人研究的基础上，给出由连续鞅驱动的倒向随机微分方程弱解的概念，利用Girsanov变换，得到其弱解存在的存在的一个充分必要条件，并在此基础上得到了其弱解存在的一些充分条件，这些充分条件减弱了在强解的存在唯一性中要求的漂移系数满足Lipschitz条件的要求。

The logic way of thought of this thesis is culture, teacher culture and teacher culture of balkanization. This thesis starts with the definition of teacher culture, and teacher groups, and teacher culture of balkanization. Secondly, on the basis of definition and comparing domestic and overseas studies, this thesis analyzes the features of teacher culture of balkanization and its form of representation. Thirdly, this thesis explores the reason of the forming of teacher culture of balkanization from three angles of view, namely individual angle, organizational angle and social angle. Fourthly, this thesis analyzes the advantages and disadvantages of teacher culture of balkanization in a dialectic way. Fifthly, the thesis ends up with principles and strategies for modifying teacher culture of balkanization.

本文首先对教师文化、教师派别以及派别主义教师文化做了概念上的界定，在此基础上，参照中西方研究深入剖析了派别主义教师文化的特征，归纳了派别主义教师文化的具体表现形式；从个人层面、组织层面以及社会层面三个维度详实探讨了派别主义教师文化的形成原因；以辩证的观点全面分析了派别主义教师文化存在的合理性与弊端；在对合理性和弊端全面分析的基础上主要针对派别主义教师文化的弊端提出了矫正原则与策略；在对全文整体把握的高度上，本文认为应当采用审慎的变革态度和方式对派别主义教师文化进行恰当取舍，对于实质上是团体个人主义的派别主义文化，其解决的根本途径是走向合作。

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。
