The principle of the generalized vector method ( GVM) has been extended to the hexagonal crystal system material under the conditions of variable axial ratio and the mathematical model on it accordingly established. 将广义矢量法原理拓展到变轴比条件下的六方晶系材料,并建立了相应的数学模型。
Molybdenum disulfide and graphite are both good lubricants because of their hexagonal crystal system. 由于MoS2与石墨都具有六方晶系的层状晶体结构,因此二者都有良好的润滑性能。
