Here is the method to get the volume from the boundary defined by a set of oriented faces defined by sets of triangles that can be oriented: if we imagine that the volumetric object is decomposed into a set of tetrahedrons, it is necessary just to calculate the sum of volumes of each tetrahedron.

用一些有方向角的集合定义一些有方向的面，再用面的集合定义边界，有一种方法可以从这些边界中得到体积。如果我们设想有体积的对象被分解为四面体的集，那么只要计算四面体的体积总和就可以了。

Also, a 2/sup 3/ factorial experimental design was applied to study the effects of temperature, rotor speed, and totalized torque on the fusion of PVC compounds.

Torque rheometer with an internal mixer is commenly applied to study the property of PVC in polymer laboratory. Compounding temperature、rotor speed、and totalized torque are three main influence factors to affect the fusion of PVC in a torque rheometer.

力矩流变仪(To-rque Rheometer)配备内部混合器是一般高分子加工实验室常用的PVC混练仪器，而此仪器影响PVC熔合最主要的混练因素为混练温度、转轴转速及力矩总和(Totalized Torque；简称TTQ)，本文应用一个2的3次方因次实验设计法来判定上述三个混练因素对PVC熔合之影响程度。
