孪晶  晶体中的两晶块以特定取向关系相交接,构成原晶体结构所不具有的(但常常是接近于原有的)对称关系时,这样的一对连生晶块称作孪晶。构成孪晶的附加对称元素包括反映面、旋转铀和对称中心,相应的孪晶称为反映孪晶、旋转孪晶和反演孪晶。    孪晶在大量天然矿物晶体及人工培育的晶体中,特别是在结构对称性较低的晶体中普遍存在着。孪晶既可在晶体生长时形成也可在此后的相变、退火及形变过程中产生,因而人们通常按其形成方式分为生长孪晶和机械孪晶两大类。具有一定几何外形的晶体,其孪晶关系常在外形上表现出来,200年前(1783年)矿物学工作者正是从天然十字石的外形首次发现孪晶的。其后的漫长岁月里,研究主要集中于孪晶的几何关系、形态学及其形成规律;20世纪初以后,由于对晶体物性研究的需要,人们对孪晶与晶体结构的关系、孪晶的形成机制、孪晶界面的结构以及它们对晶体物理性质的影响方面,进行了大量研究工作。    参考书目   R.W.Cahn,Twinned Crystals,Advance in Physics,Vol.3, p.363, 1954.
