Chapter 2 is devoted to study of exact solutions of the nonlinear evolution equations. Using solutions of a Bernoulli equation instead of tanh in tanh-function method we find some more general solutions of the KdV-Burgers-Kuramoto equation , and by using the nonlinear telegraph equation we show that there are many different choices on its balancing number m and the power n of the nonlinear term in Bernoulli equation by which we can recover the previously known solutions and also can derive new square root type solitary wave solutions. Exact solitary wave solutions for a surface wave equation are obtained by means of the homogeneous balance method. We also present an approach for constructing the solitary wave solutions and non-solitary wave solutions of the nonlinear evolution equations by using the homogeneous balance method directly, which is also used to find the steady state solutions, solitary wave solutions and the non-solitary wave solutions of the 2+1 dimensional dispersive long wave equations. The soliton-like solutions of the BLMP equation and the 2+1 dimensional breaking soliton equation are found by use of the symbolic-computation-based Method.

And when she buries a Man, that action concernes me: All mankinde is of one Author, and is one volume; when one Man dies, one Chapter is not torne out of the booke, but translated into a better language; and every Chapter must be so translated; God emploies several translators; some peeces are translated by age, some by sicknesse, some by warre, some by justice; but Gods hand is in every translation; and his hand shall binde up all our scattered leaves againe, for that Librarie where every booke shall lie open to one another: As therefore the Bell that rings to a Sermon, calls not upon the Preacher onely, but upon the Congregation to come; so this Bell calls us all: but how much more mee, who am brought so neere the doore by this sicknesse.

当教堂埋葬了一个人，这个行为亦涉及到我：芸芸众生，可看作一卷书籍，其作者只有一个；当一个人死去，代表他的那一章并没有从书中撕去，而是被翻译成一种更好的语言；书中的每一章都会被这样译成更好的语言；上帝雇佣了几个翻译家；有的章节由"年迈"翻译，有的由"疾病"翻译，有的由"战祸"翻译，还有的由"司法"来翻译；不过在所有的译作里都看得见上帝的手；他的手把我们全部散落的书页又重新装订在一起，送回图书馆，那儿，每本书相互敞开，一本挨着一本放好：所以，正如宣布讲道开始的钟声不仅呼唤讲道者开讲，也呼唤信众来听讲一样，这口丧钟呼唤的是我们大家：尤其是呼唤我，呼唤我这个被疾病带到离门口如此之近的人。

And by using the initial conditions as well as the end conditions, the dynamic problem is then transferred to a second kind Volterra integral equation about the function of the axial strain with respect to time which can also be solved successfully by the interpolation method.
