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.

Vegetative agriculture is a kind of productive system, which concentrates mainly on the production of vegetative organs such as stems and leaves of plants including herbages, green fodder, vegetations, flowers, teas, tobaccos, as well as rhizome and fibre crops. The principal difference between the traditional agriculture and vegetative agriculture is that the former focuses on the productivity of the seed in the whole growing period and the latter focuses on the productivity of available nutrients at the different growing stages of plants.

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。

At the same time, due to 2~1S_0、 3_1S_0 are the radical excitations of 1~1S_0,we can use Regge trajectory on the (n,M~2)-plane with the approximate same slope to describe the mass of isoscalar of 3~1S_0 nonet (1926MeV). The two results derive from different ways are approximate. 2 The mass of the isodoublet of 2~3S_1 nonet is analyzed in the quarkonium-quarkonium mixing scheme, the results (1584±16.7MeV) is far from the K~*(1410)(1414±15MeV). 3 Based on "glueball dominance" picture, we establish glueball-meson mass relations. For the 2~ glueball mass and 4~ glueball mass used as input parameters, these relations predict the mass of isoscalar of 1~3F_4(4~)(2076±19.66MeV).
