Besides conventional conditions,the standardized setting of 2 lattice for compute identi- fication of minerals lays on extra restrictions which are:(1)c<><><β≤120°for="" monocliniic="">orthorhombic system.
为满足计算机检索的需要,新的晶胞选取原则对低级晶族矿物额外增加了限制条件,斜方晶系要求满足不等式 c<>a,β角在90°—120°之间;三斜晶系要求 c<>
The interplanar spacing and conversion trend of wax crystals are increased from orthorhombic crystals to hexagonal crystals for the colloid and asphaltene existing,showing short-rang.
5%,表现为长程有序;原油组分中胶质和沥青质的存在增大了蜡晶转化成斜方晶型的趋势,使蜡晶的晶面距增大,蜡晶表现为短程有序,这种转化依赖于原油组分的性质和含量;降凝剂降低蜡晶体的有序度,晶面距增大到0。
