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。

Eight or nine years after the events narrated in the second part of this story, people noticed on the Boulevard du Temple, and in the regions of the Chateau-d'Eau, a little boy eleven or twelve years of age, who would have realized with tolerable accuracy that ideal of the gamin sketched out above, if, with the laugh of his age on his lips, he had not had a heart absolutely sombre and empty.

在本故事第二部分谈到的那些事发生后的八年或九年左右，人们在大庙路和水塔一带，时常看见一个十一二岁的男孩，嘴边带着他那样年纪所常有的笑容，心里却是绝对的苦闷和空虚，如果不是那样，他便相当正确地体现了我们在前面勾画过的那种野孩的形象了。

There was an increasing demand for engine power due to industrial development. As early as the 2nd century BC, the ancient Greeks invented an engine that was powered by the reaction from spurting steam; in 1690, the Frenchman Barben invented the first piston steam engine. On the basis of his predecessors' work and with his own hard work and numerous trials and failures, James Watt invented the steam engine with connecting rod, flywheel and centrifugal speed governor in 1782.In 1784, the British government granted a patent to James Watt for producing steam engines, which signified that man had entered the age of the steam engine and also significantly expedited the beginning of the Industrial Revolution in 18th century Europe. By the 1830s, steam engines had been widely used in various sectors such as textile, metallurgy, coal mining and transportation; for example, the American Robert Fulton invented the steamboat and the Englishman George Stephenson invented the steam locomotive.

随着社会的进步，社会由农业时代进入工业时代后，对全用手工操作已十分不满足，人们随着工业发展对动力的需求日益突出，瓦特在前人研究蒸汽的基础上，甚至早在公元前二世纪，古希腊人创造的一种利用蒸汽喷射的反作用的发动机，以及1690年法国人巴比首先发明第一台活塞式蒸气机等，刻苦钻研，反复实验，经历无数次挫折和失败，终于在1782年发明了具有连杆、飞轮和离心调速器的双动作蒸气机，使之成为了可以实用的蒸气机。1784年英国政府授予瓦特以制造蒸气机的专利证书，这标志着人类进入了蒸气机时代，有力地促进了欧洲18世纪的产业革命。
