But when I turn from that abstract right and that abstract expediency to our own state of society — when I consider how difficult it is for any Judge to separate the case which requires inflexible justice from that which admits the force of mitigating circumstances — how invidious the task of the Secretary of State in dispensing the mercy of the Crown — how critical horror becomes the theme of sympathy and pity — how narrow and how limited the examples given by this condign and awful punishment — how brutal the scene of execution — I come to the conclusion that nothing would be lost to justice, nothing lost in the preservation of innocent life, if the punishment of death were altogether abolished .

但是，当我从那抽象的权利和抽象的权宜行使回视我们的社会情态时，当我考虑到任何法官在试图分辨哪个案件只能是无弹性的审判哪个案件是可以适用减轻情节的面对的困难时，当我考虑到内阁的大臣在适用 the mercy of the Crown 时是多么的容易招致争议时，当我考虑到一个极具争论性的令人恐怖的事情是怎样变成同情和怜悯的浪殇时，当我考虑到这个似乎应当而又可怕的惩罚所能提供的勉强而又有限的例子和其执行场面之凶残的时候，我更愿意得出这样的结论，如果死刑被全部废除，在保存正义和无辜的生命面前，没有什么会失去。

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。
