Considering the mass-velocity relation and mass-energy relation, an object's inertial mass isn't equal to its gravitational mass in some cases; under the conditions of equality of velocity, temperature, pressure and the like, an object's inertial mass may be equal to its gravitational mass.

摘 要 考虑质速关系和质能关系可以得出结论：并非在任何条件下一个物体的惯性质量和引力质量都相等；在等速、等温、等压等条件下，一个物体的惯性质量和引力质量可以相等。

In addition, if the several factors that cause the change of mass can be counter-balanced or create the equivalent result, an object's inertial mass will be equal to its gravitational mass. For example, an object's inertial mass with high temperature and low pressure may be equal to its gravitational mass with low temperature and high pressure.

此外，如果引起质量变化的几种因素可以抵消或产生等效的结果，一个物体的惯性质量和引力质量也可以相等；例如一个物体在高温低压状态下的惯性质量和低温高压状态下的引力质量也可以相等。

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.

gravitational mass：引力质量

在万有引力定律中引入的物体质量, 称为引力质量(gravitational mass). 引力质量与在牛顿运动定律中引入的惯性质量(inertial mass)一样, 也是物体自身的一种属性的量度, 它表征了物体之间引力作用的强度. 虽然引力质量和惯性质量代表了物体的两种不同的属性,
