The paper has studyed the characteristics of seismic wave field in the media of EDA, and has made out three aspects of numerical simulation on wave field features by using definite difference: The simulation of P-wave ground seismic logs in the media of EDA; the diagnostic complication of seismic wave field in cranny belts due to the scattering of cranny wrappage; the decreasing of amplitude and the reversing of polarity of the wave reflected on not only the top but also the bottom of fracture zone.

2通过罗67井岩芯的系统研究表明，泥岩的横波和纵波速度随温度增大而降低，一定温度条件下随为压力而增大；泥岩裂缝的测井曲线一般表现为高电阻率、负自然电位异常、低声波时差，利用该规律可以半量定地识别划分泥岩裂缝储层特征，为解决不同度数据的相互匹配这一重点和难点问题提供了思路和方法。

Can say with certainty that the Government is aware of "internal and external problems" of economic growth facing unprecedented pressure, perhaps, China has entered a new round of rate cut cycle.

As she put it in The Common Reader ,"It is safe to say that not a single law has been framed or one stone set upon another because of anything Chaucer said or wrote ; and yet , as we read him , we are absorbing morality at every pore ."

就像她在《致读者大众》一书中所表达的那样，&可以肯定地说，乔叟的话语和作品没有制定任一部法律或建立任何；然而，当我们阅读他的书时，我们身上每一个毛孔都在吸收道德观。&

I contemplate my age calmly, as if viewing a little-by-little impending sailboat.
