如果这些条件得到满足，则可惟一地构造简单连接弹簧-质点系统，并给出了构造真实物理系统的一个算法。

If these conditions are satisfied, the simply connected spring-mass system may be constructed uniquely. An algorithm is used to construct the physical realizable system from the data.

在虚拟环境中，对人体头部变形曲面提取特征并参数化，建立基于弹簧质点系统的标准几何模型；

In a visual environment, the characters of transformative head surface were parametrically drown out and a standard geometrical model of head was established based on the spring mass system.
