But it is a hard task to solve this equation, one reason is that the TV-norm is nondifferentiable when |▽_u|= 0, so we cant apply a linearizationtechnique such as the Newton method. The other reason is that the Euler-Lagrange equation has a highly nonlinear term. The Newton method for such equation is known to have a very small domain of convergence, and it is very difficult to make sure that the initial value such as the observed image belongs to this domain. So the Newton method is not an ideal method for solving this equation.

但是求解它比较困难，主要是因为TV-范数在|▽u|=0处不可微，不能用诸如牛顿法之类的方法将其线性化；且Euler-Lagrange方程含有一个高度非线性的项，牛顿法只有局部收敛性，对于高度非线性问题它的收敛域很小，因此难以保证所取的初始点在它的收敛域内，故一般不用牛顿法直接求解。

According to induced response method, the expression in frequency domain of pressure response at the end of pipeline is derived using impulse response method and convolution theorem. The expression indicates that that transfer function is only related to the characteristics of pipeline system and the Fourier transform of flow variable only depends on the operating characteristics, and the pressure response in frequency domain is linear with the Fourier transform of flow variable.

基于激励响应法，应用脉冲响应方法和卷积定理得出了管道末端压力响应在频域中的表达式，此式表明：传递函数只与系统的特性相关，流量变量的傅立叶变换只与操作特性相关，且压力频域响应与流量变量的傅立叶变换为线形关系，根据此式在理论上能够得到管道泄漏点的重要信息。

So say American film society to sue fast thunder can additional purposeful, these year western country always censures China in intellectual property domain, because,force of fire of before a few years of Zhuhai is sued by SIGMATEL of provider of American MP3 chip also is intellectual property, the swift and violent development that real reason is Zhuhai fire force truly has browbeaten SIGMATEL, the intellectual property case that SIGMATEL prosecutes Zhuhai fire force also is absent MP3, and in domain of power source power comsumption, allegedly the period of time of to lodge a complaint, the client of force of many Zhuhai fire converts SIGMATEL, because,very simple everybody does not consider the matter the lawsuit ask for trouble of Zhuhai fire force, this just also is the real reason that SIGMATEL sues Zhuhai fire force, do sth over and over again prosecution of two years is Zhuhai fire force as a result eventually most reconcile in both sides of Shenzhen countercharge SIGMATEL, the judgement that the market share of force of final Zhuhai fire exceeds SIGMATEL to became the MP3 chip provider with the greatest whole world to also prove SIGMATEL is original and be anxious.

这么说来美国电影协会起诉迅雷只能另有目的，这些年西方国家总是在知识产权领域指责中国，前几年珠海炬力被美国MP3芯片提供商SIGMATEL起诉也是因为知识产权，真正的原因确是珠海炬力的迅猛发展已经威胁到SIGMATEL，SIGMATEL起诉珠海炬力的知识产权案也不在MP3，而在电源功耗领域，据说提起诉讼的一段时间，大量珠海炬力的客户都转投SIGMATEL，原因很简单大家都不想因为珠海炬力的官司惹火上身，这也才是SIGMATEL起诉珠海炬力的真正原因，折腾了两年的起诉最终结果是珠海炬力在深圳反诉SIGMATEL双方和解，最后珠海炬力的市场份额超过SIGMATEL成为全球最大的MP3芯片提供商也证实了SIGMATEL最初的判定和担忧。
