Pin群
只有其中两个称为 Pin 群,他们可以将 Clifford 代数作为一个表示。他们分别称为 Pin(p,q) 和 Pin(q,p)。
命名
这个群的名称在 迈克尔·阿蒂亚、拉乌尔·博特、A. 这是“Spin”的逆构词法:Pin 之于 Spin 就像 O(n) 之于 SO(n),从而从“Spin”中去掉“S”得到“Pin”。进一步,词“Pin”的法语发音和一个粗痞话相同,这暗示了这个名称的起源于(或被归于)塞尔。

Pinterest“喜欢(鸡心)”与pin区分的原因是什么?
pin是转载的样子,like是喜欢的样子。 你喜欢就喜欢,可以说出来,那就pin一下喽;那你害羞,只想默默的喜欢着,就like咯。 话说我的tumblr也是当Pinterest来用的,不过感觉用法不太对,因为Pinterest支持创建多个画册来对你要Pin的东西分类,所以区别二:pin的时候可以分类,LIKE的东西只有时间顺序可依

PIN型二极管
如果I层材料为低掺杂的P型半导体,则该二极管可称为π型PIN二极管;如果I层材料为低掺杂的N型半导体,则该二极管可称为ν型PIN二极管。在PIN型二极管中,P层和N层通常由高掺杂的半导体材料组成。由于I层的存在,PIN型二极管通常比普通的二极管拥有更宽的耗尽层,更大的接面电阻和更小的接面电容。 当在PIN型二极管上施以正向偏置的直流电时,PIN型二极管允许高频振荡的整个波形通过二极管,此时,PIN型二极管基本等同于一个电阻值极小的线性电阻器。当在PIN型二极管上施以反向偏置的直流电时,PIN型二极管基本等同于一个电阻值很大的线性电阻器和一个电容器的并联。
