Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

Since all javascript syntax functions derive themselves from the base-class function, it is unnecessary to provide an explicit reference to the self-object: from anywhere within an ECMA-style script, you can obtain a reference to the self-object through the keyword "this", which is the same as the "me" keyword, but with minor differences.

因为所有的javascript语法中函数都是从基础类函数派生而来，它们不必显示的声明指向自己的对象：在ECMA风格脚本的任何地方，你都可以通过关键字"this"获得指向当前对象自己的引用，就象关键字"me"的功能一样，只是稍有不同。
