To attain the same strength grade, the content of cement in cement fly-ash stabilized hoggin has reduced by 0.5~1% comparing with cement stabilized hoggin. This material has a capability of adapting with different aggregate's gradation and the 4.75mm passing rate can reduce to 30%. Through the studying about the mechanical property of cement fly-ash stabilized hoggin, this manuscript discover that the material has good strength growing performance that its 90d strength growing rate is 385% and its splitting strength that the 7d splitting strength is 0.347MPa and the 90d splitting strength is 0.700MPa accord with requirement in the norm.

粉煤灰处于最佳掺量时，通过粉煤灰的填充、活性等作用，使材料在达到相同强度等级，水泥剂量降低0.5～1%；并且对集料级配具有更好的适应性能且能使集料4.75mm以下通过率降低至30%左右；而且能有效提高材料的强度增长率，90d强度增长率高达385%左右；同时，降低回弹模量16%左右，对材料的抗裂性能有显著的改善作用。

The company invests mount a horse the project of form a complete set of cooking of defer of 1 million T hydrogenation of 800 thousand T refines and 30 thousand T is sulfureous reclaim project, quality of farther promotion product, reclaim effectively the 2 oxidation sulfur in waste gas, have major economic benefits and social benefit; to invested many yuan 6000 to build two dry gas to make hydrogenous device, make waste gas reclaims rate achieved 95%, reduced the discharge capacity of waste gas substantially, reduce; of the cost that make hydrogen to be in greatly at the same time more than heat, beyond pressure, of more than gas used a respect integratedly to carry out 22 technical reformation, make enterprise ton the banner level that oily treatment specific power consumption reached industry of domestic person of the same trade.

Their common vision is to release painting from the obsession of the virtual 3D dimension created by perspective and from the dependence on formula with an aim to clarify the identity of contemporary art of painting. Their effort helps painting restore to the painting process and to the effective presentation of simple and unique material and idiosyncracy.

他们有着一个共同的目标就是想通过自己的角度来澄清当代绘画艺术的本体论问题，使绘画摆脱对图式的依赖和借助透视法制造虚拟的三维空间的执迷，使绘画回到了绘画的"过程"之中、回到对朴素而又极具个性的材料特质的有效表现之中。

The larger part of the collective existence of every community is consumed in transactions of buying and selling, of letting and hiring, of alliances between men for purposes of business, of delegation of business from one man to another; and this is no doubt the consideration which led the Romans, as it has led most societies, to relieve these transactions from technical incumbrance, to abstain as much as possible from clogging the most efficient springs of social movement.

每一个社会的集体生存，其较大部分是消耗在买卖、租赁、为了商业目的而进行的人与人之间的联合、一个人对另一个人的商业委托等等交易中；这无疑是使罗马人象大多数社会一样，考虑到把这些交易从专门手续的累赘中解脱出来，并尽可能使社会运动最有效的泉源不至阻塞。
