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。

Moreover, we consider that the mass of an atom contains two parts: the intrinsic-mass and the binding-energy-mass, the former mass cannot be converted into energy, while the latter mass can be converted into energy directly in accordance with the mass-energy relation. Besides it\\\s shown clearly that the so-called mass-energy conversion is essentially the release of binding energy in the atoms.

我们认为原子的质量包含两部分：本征质量和结合能质量，前者不能直接转换为能量，后者可以依照质能关系转换成能量，这种质能转换本质上是原子内部结合能的释放。

Assistance to the Air Force to carry out the expansion. After the war, into the development phase of the restoration, completed basic combat training and logistical support systems, combat aircraft to achieve the beginning of jet. 60 era for the expansion and gradually equipped with F-86D, F-5A and F-4F fighter. 80s equipped with F-5E/F, F-16 fighter aircraft, air defense automated alert system officially running. In July 1991, the Army air defense artillery and troops under the command of the Air Force formed to form a radar, aircraft, surface to air missile (anti-aircraft) integrated air defense system. 90, to receive from the U.S. military operational command, weapons and equipment have been developed, the first home-made aircraft KF-16 aircraft factory, F-16 fighters equipped with AIM-120 advanced air-to-air missile in the distance, procurement from France,"Northwest Wind "-air missile. 2002 selection of a new generation of F-15K fighter jets.

The main reason is that many high-grade office space is equipped with all-air central air conditioning, is to first deal with air, reducing temperature and humidity, the air sent through the pipeline to the room through the return air, pipeline to return to the central processing system, central processing system for cooling air return after降湿part of the new wind coupled with the second round after the blast, and so the cycle, while the central air-conditioning system for energy conservation, often adding a little fresh air, return air devices in the recovery rate of 80%, resulting in cross-infection the opportunity to increase significantly.

主要的原因是，许多高品位的办公空间配备了全空气中央空调，是先处理空气，降低温度和湿度，空气通过管道传送到房间通过回风管道返回中央处理系统，中央处理系统，冷却空气降湿后返回的一部分，新风，加上第二轮爆炸后，所以周期，而中央空调系统节能，往往增加了小新鲜空气，回风装置，回收率为80 ％，导致交叉感染的机会大大增加。
