摘　　要：晶体投影是研究晶体外形和晶体结构的一种重要工具,特别是极射赤面投影与心射切面投影在材料科学、地质科学等研究领域得到广泛的运用。基于晶体投影的原理,把晶体的投影过程模型化,首先制作了不同类型晶体的倒易点阵模型,再将各倒易点阵模型上的倒易结点从原点投影到球上得到相应的模型参考球。然后通过变换点光源的位置以及参考球的取向可在投影屏上得到不同类型晶体的各种投影图像,并可投影模型作为实用工具用于教学与科研。The projection of crystal is a powerful tool for the study in the shape and structure of crystal. Especially, the stereographic projection and centric projection are used widely in the study field of science of material and geology. Based on the principle of the projection of crystal, the author turned it to modelling. Firstly, the models of various kinds of reciprocal lattices were created, then from the origin the reciprocal nodes of the reciprocal lattices were projected to the face of a sphere and a corresponding model spheres were obtained. Afterward,by changing the location of the lamp- house and the orientation of the model spheres, various projection image of different kinds of crystals can be showed in the screen of the model. The model also can he used in the teaching and research as an applied tool.
