Ice β-XV – a novel ice polymorph

Water molecules can form different hydrogen-bonded networks, a property known as ice polymorphism. So far 18 different networks have been characterized using neutron diffraction...水分子可形成多种不同的氢键网络，这一特性被称为冰多形性（ice polymorphism）。截至目前，已有18种不同的氢键网络通过中子衍射（neutron diffraction）技术得到表征。
