Soft-tissue deformation is one of the important research directions in virtual surgery. Mass-spring model and finite-element model are the two most important modeling technology of the soft tissue modeling. It is very important for the current soft-tissue deformation model ing to analysize, to summarize the main idea, the influence factors and the modeling route of the two kinds of modeling methods and then to give comprehensive review.%软组织形变是虚拟手术的重要研究方向之一。质点-弹簧模型和有限元模型是当前软组织建模的两种最重要的建模方法。该文对这两种建模方法的主要思想、影响因素以及建模路线，进行分析和概括，做一个比较全面的综述，对当前的软组织形变建模具有重要的参考价值。
