Triangle lens is best in uniformity, and hexangular lens has better light collecting efficiency.

利用三角形积分透镜可以获得最佳的照明均匀性，但光能利用率相对较低，六角形积分透镜可同时获得较高的照明均匀性和光能利用率。

When Tenen broke the first word of Genesis into its 'subatomic particles'(the word is actually comprised of two smaller words, meaning "fire" and "six-edged thorn"), he took the "thorn" to mean a tetrahedron and constructed a model of it, placing the "fire," or torus "vortex" form, inside.

当特纳把创世纪的首个单词拆分成&亚原子粒子&（这个词事实上是由两个较小的单词组成，意思分别是&火&和&六角形&），他用&角&这个词来代表一个四面体，并且为它建立了模型，把&火&，或者是花托状的&旋涡&放在里面。
