The physics in the past puts the issue that is in a lot of notting allow that ignore in course, if be with knowledge this curricular design restricted course to be in the educational function of domain of affection, manner and domain of viewpoint of value and scientific process, scientific method, the learning of equalize asked to contuse the student is mixed to the feeling of nature and science and technology interest, compact discipline system expands innovation spirit of the student and practice capacity hard.

在过去的物理课程中存在许多不容忽视的新问题，如以知识为本的课程设计限制了课程在情感、态度及价值观领域和科学过程、科学方法领域的教育功能，划一的学术要求挫伤了学生对自然和科学技术的感情和喜好，严谨的学科体系难以发展学生的创新精神和实践能力。

Conventionalism and Realism are generally believed that it is difficult to reconcile.

约定论与实在论一般认为两者是难以协调的。

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。
