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。

The results showed that the pressure and pressure derivative of non-newtonian fluid is higher than newtonian one;The power index is more smaller,the pressure and pressure derivative is more higher;The effect of skin factor on transient was different from that of power index;The storativity ratio and inter-porosity flow factor is just same as the newtonian fluid,and the effect of outer-boundary on transient pressure is different from that of newtonian fluid.
结果表明,非牛顿流体的压力及压力导数都明显高于牛顿流体;幂律流指数越小则压力和压力导数越大;表皮系数和非牛顿流体幂律流指数对压力响应的影响有着明显的不同;而弹性储容比和窜流系数的影响和普通三重介质相同,只是由于非牛顿流体的影响其"凹陷"的位置升高;外边界的影响也和牛顿流体的情况明显不同。
