The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

Then, the differential equations are solved by the Fourier expanding and Hankel integral transform method. Integral solutions of soil skeleton displacements and pore pressure as well as the total stresses for poroelastic media are obtained. Furthermore, a systematic study on Lamb's problems in transversely isotropic saturated half-space is performed. Integral solutions for surface radial, vertical and tangentical displacements are obtained both in the case of drained surface and in the case of undrained surface excited by vertical and tangentical harmonic resources respectively. Numerical results show the obvious difference between the model of isotropic saturated poroelastic media and that of transversely isotropic saturated poroelastic media.

其次，基于Biot波动理论，在圆柱坐标系下求解了横观各向同性饱和土的Biot波动方程：通过引入位移函数，在圆柱坐标系下将横观各向同性饱和土的Biot波动方程转化为两个解耦的6阶和2阶控制方程，然后根据方位角的Fourier展开和径向Hankel变换，求解波动方程，得到以土骨架位移和孔隙水压力为基本未知量的积分形式一般解，并用一般解给出了饱和土总应力分量的表达式；再以基本解为基础，系统地研究了横观各向同性饱和半空间体的Lamb问题，考虑表面排水或不排水两种情况后，首次得到横观各向同性饱和半空间体在表面竖向和水平谐振力作用的下径向、竖向和周向位移的解析解。

Suzanne Vega - Tom's Dinner I am sitting in the morning At the diner on the corner I am waiting at the counter For the man to pour the coffee And he fills it only halfway And before I even argue He is looking out the window At somebody coming in "It is always nice to see you" Says the man behind the counter To the woman who has come in She is shaking her umbrella And I look the other way As they are kissing their hellos I'm pretending not to see them And instead I pour the milk And I open up the paper There's a story of an actor Who had died while he was drinking It was no one I had heard of And I'm turning to the horoscope And looking for the funnies When I'm feeling someone watching me And so I raise my head There's a woman on the outside Looking inside. Does she see me?

清晨， 我坐在拐角处的小饭馆在吧台前，等那个男人给我倒咖啡他居然只倒了一半的量---我正想跟他抗议他看向窗外，有人快要进来"见到你总是很高兴"吧台后的男人对进来的女人说女人正抖落伞上的水珠我转头看向另一边他们亲吻对方装着没有注意他们我倒了些牛奶打开报纸有篇关于一个演员的文章在他饮酒时死去不过是某个人物罢了我开始看星象栏目寻找有趣的东西突然感觉有人在注视我于是抬起头外面有个女人正看向里面她看见我了么？
