The results indicate that its dynamic stress-strain curve is hyperbolic type. The dynamic strain of LCES decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency when it is subjected to the same dynamic stress. At the same dynamic strain, the dynamic secant elastic modulus E_(sec of LCES increases and the damping ratio decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency. The curves ofσ_d～ε_d,E_～ε_d and D～ε_d with different EPS content intersect respectively, the trend of LCES deformation characteristic is inversely proportional to EPS content near the intersection. The value of dynamic strain at the intersection is about 0.5%~3.0%, the magnitude of which is related to the mixing proportions and confining pressure.

试验结果表明，LCES的动应力应变骨干曲线形态符合双曲线；在相同的动应力作用下，LCES产生的动应变随着固结压力、水泥掺量、试样养护龄期和振动频率的增大而减小；在动应变相同的情况下，随着固结压力、水泥掺量、试样养护龄期和振动频率的增大，LCES的动模量增大而阻尼比减小；随着加载次数的增大，LCES的动模量在开始阶段显著降低，然后趋于稳定，但当加载次数达到几百次时，动模量又有增大的趋势；不同EPS掺入比的LCES的动应力应变骨干曲线、动模量随应变变化曲线和阻尼比随应变变化曲线都发生了相交，交点前后EPS掺入比的大小对LCES动力变形特性的影响趋势是截然相反的，交点处的动应变值一般在0.5％～3.0％范围内变化，其大小与LCES的配比以及固结压力有关。

The reason the entrepreneur is an entrepreneur is that he has a strong desire of initiate enterprise .such desire is as same as the the one of drawer and author for inditement .the desire of an entrepreneur is to make things happen-to make things that never exist happen .the approach he chooses is action ,or operation .his pleasure lie in things done effectively and conclusion made correctly .it is money that turns his pleasure into substance .money is the sign of success ,but not motivity necessarily .to tes ...

企业家之所以成为企业家，靠的是开创事业的强烈的欲望，这种欲望同画家和作家的创作欲望并无二致。企业家的欲望是让事情以生，让从前未曾有的事情发生，他所选择的途径是行动，或者说是以营。他的乐趣在于看到事情办得有成效，决定做得正确。使他的乐趣变得实实在在的是金钱。金钱是成功的标志但未必是动力。检验这一点很简单：如果一个企业家突然得到他想要的那么多金钱，他会停止营业呢，还是会用这笔钱去发展经营？历史表明，企业家多半会去开拓新的经营活动。

The general laws of evolvement show the following features:①The point and line contacts of grains decreased;②The communication degree of pore with throat increased.The grading of pore and throat got meliorative;③The total content of clay was reduced;④The wettability of rock trended to hydrophile.The distribution of remaining oil in reservoir was controlled and affected by the pore-throat-net evolvement.

研究结果表明，储层孔喉网络演化是由油藏开发流体动力地质作用所造成的，孔喉网络场的演化是动态的、持续发生的，孔喉网络场总的演化规律是：颗粒点、线接触关系减少；孔喉连通程度提高，喉道分选性变好；粘土矿物减少，各类粘土矿物相对含量变化；岩石颗粒的润湿性向亲水转化。
