variable expansion造句

The proposed algorithm is called agvf snake algorithm . when deformable models are used to extract brain contour from the head mr images , problems associated with initialization and time consuming iteration limit their utility . to overcome these problems , a region based variable expansion force is proposed
对于可变形模型对初始轮廓的依赖较大，外力的作用范围有限，迭代算法收敛时间较长等问题，提出了一种新的外力，我们称之为基于区域的可变膨胀力( regionbasedvariableexpansionforce ) 。
It's difficult to find variable expansion in a sentence. 用variable expansion造句挺难的
