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.

Twice a year Northwestern Georgia celebrates its cultural traditions on the grounds of a historic water-powered mill. The Prater Mill, located on the Coahulla Creek, was built by Benjamin Franklin Prater in 1855. During the Civil War, the mill was used as a campsite for soldiers on both sides. Since it was considered an important source of food, it was not destroyed. The Prater family operated the mill until the 1950s.

住在乔治亚西北部的居民，每年会在具历史意义的水力面粉厂内举办两次庆祝当地文化常规的庆典；座落于 Coahulla Creek 的普拉特面粉厂建于1855年，建造者是班杰明普拉特；内战时，这间面粉厂曾被敌对的双方拿来做为军营，因为它是重要的食物来源，所以未遭摧毁；直到1950年前，这间面粉厂的经营者一直是普拉特家族。

The results show that the hydraulic fracturing pressure is intimately related with tensile strength and tridimensional stress state of the soil. With the increase of tensile strength and minor principal stress, the fracturing pressure is enhanced.
