# 密排六方晶体面间距的计算Calculation of Interplanar Spacing in Hexagonal Close-Packed Crystal

Abstract: Based on a principle of analytic geometry, a “site-factor S” of an addition atom was suggested to take as a tool for calculating interplanar spacing. With the “site factor S”, the interplanar spacing of hexagonal close-packed crystal was calculated and confirmed by some examples, and the result showed that it has 6 kinds of possible interplanar spacing. The correlativity between the interplanar spacing and the structure-factor were analysed, and relation between the additional plane and the missing reflection plane was discussed.
