Examples
- If a set contains no elements we shall designate it by Ф and define it as the empty or null set .
如果一个集合不包含元素，我们就把它记为，且定义它为空集或零集。 - Solid modeling and applications , seattle , usa , 2003 , pp . 262 - 265 . 18 gielis j . a generic geometric transformation that unifies a wide range of natural and abstract shapes
物体的表面，即相应于所得隐函数的零集，可通过超形的参数化形式直接高效地生成多边形来表示。 - Savchenko v . function representation in geometric modeling : concepts , implementation and applications . the visual computer , 1995 , 11 : 429 - 446 . 23 rvachev v l . geometric applications of logic algebra
尽管相交曲线是逼近计算的，相关的顶点还是用超形的参数化形式计算的，表明它们属于隐函数的零集，但不会精确地位于理论上的相交曲线上。 - The solution regards the original given interface ( original curve or interface ) as one zero set of function , transferring the some phenomena such as topology to lever set function in higher dimension , and getting moving interface of original interface at different time through resolving the level set function
水平集方法是把最初给定的截面(原始曲线或面)看作是某个函数零集，把求解等距过程中发生的拓扑等现象转移到高一维的水平集函数中去，通过求解该水平集函数以得到原始截面不同时刻的等距面。
