Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

All enhancers did not significantly change the transcorneal lag time of ENX. The irritancy of poloxamer and Azone was observed.? The results of in vitro release studies showed that the ENX gel based 3% HPMC K4M and 3%HPMC F4M povided sustained release of the drug over an 8-h period in vitro.Diffusion area has significantly effect on drug release, and pH value of medium and rotation rate have effcet on drug release.However, the diffusion shield has no effect on drug release. The P_ value of the preparation based on 3% HPMC F4M was 1.34-fold of conventional eye drops of ENX.

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

Then the Hadley circulation in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced, followed with the moment of momentum taken by its ascending branch increased in the Western Hemisphere while weakened in the Eastern Hemisphere. The PNA pattern is enhanced and the Pacific-East Asian teleconnection is weakened. As a result, the atmospheric circulation's response to the ENSO events in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced.
o事件使Walker环流减弱及其上升支东移的现象更明显,Hadley环流在东半球减弱而在西半球增强,由其上升支带至中纬的角动量在东半球减少,西半球增多,造成影响西半球大气环流的PNA型遥相关增强,影响东半球的太平洋-东亚型遥相关减弱,进而使得ENSO对东半球大气环流的影响减弱而对西半球大气环流的影响则有所增强。

The macroeconomics has demonstrated the relation between investment and economical growth. Investment affects the general demand and GDP via multiplicator. On the other hand, the fluctuation of GDP affects investment via accelerated vector. There exists a relation between GDP and investment. A macroeconomical seasonal fluctuation represents a slack or climax under the effect of GDP and investment. Chronically, investment and GDP growth will arrive at equilibrium, and GDP shows disciplinarian fluctuation.
宏观经济学论证了投资与经济增长之间的关系,投资通过乘数影响总需求进而影响国内生产总值,而GDP的向上或向下的波动又通过加速数影响投资,二者是动态的关系,在投资乘数和加速数的共同影响下,出现宏观经济的周期性的波动,表现为宏观经济的高涨和萧条,投资和经济增长在长期将达到均衡状态,使得GDP呈现出有规律的波动。
