In this paper, we prove a theorem on the convergence of the gradient of K-S function to the subdifferential of corresponding maximum function. 该方法利用最大似然准则建立目标函数，同时利用非线性共轭梯度法来优化求解目标函数。ĭue to cardiac deformation and blood flowing, weak edges, local gradient maximum regions and artifacts are found in the MRI images. The objective function was established based on the maximum likelihood rule, which was solved by nonlinear conjugate gradient method.

Moreover the isogram chart of countrywide maximum temperature gradient of concrete pavements with frequency of 2% is plotted. gradient computation is described and the formula for computation of maximum gradient is derived. The traditional MGD ( maximum gradient difference) algorithm based on the order of the image pixels matrix has the shortcomings of the large operation measure and long-time running. It is used for extracting linear feature from magnetic and gravity data. 温度垂直梯度越大，它在垂直方向上阻碍上层海水的热量往深层扩散的能力就越强。Ī maximum gradient tracing and rotation transformation approach is presented in this paper. The greater the vertical maximum gradient is, the more powerful its capability to block vertical heat diffusion from upper water layer to deep water layer.
