中文摘要：
合成Sb-S-Se体系中硫、硒代换的实验研究显示，辉锑矿一硒锑矿系列是由于硫-硒代换形成的二元固溶体系列。该系列的两个端元成分分别是Sb2S3与Sb2Se3。在该二元固溶体系列中，硒含量的变化是完全连续的，显示出硒对硫的取代，是以无序取代和完全混溶的方式进行的。故其为一个完全混溶的二元固溶体系列。同时，随硒含量的增加，该二元固溶体系列的矿物结晶学参数有规律性的变化。即晶胞参数a，b，c值与晶胞体积y值、矿物密度D值，均随硒含量的增加而增大。
英文摘要：
A series of experiments on the Sb-S Se system were conducted at 300 C. The stibnite-antimonselite solid solution series was established in terms of the experimental data. By experimentally substituting S for Se,the compositions of S-rich and Se-rich endmembers are confirmed as Sb2S3 and Sb2Se3 respectively. Based on Se/（S＋Se） ratios from microprobe analysis ,this binary system of stibnite-antimonselite is quarterly divided into stibnite,selenium stibnite,sulfur antimonselite and antimonselite. The selenium stibnite and sulfur antimonselite are varieties between the two end members of stibnite and antimonselite. Micro-hardness of the stibnite sub-series （ωSb=60.11% to 72.58% ,ωS=13.20% to 27.63%,ωSe=0 to 27.23%） and the antimonselite sub-series （ωSb 49.29% to 59.25%,ωSe=28.89% to 51.94%,ωS=0 to 12.10%） vary from 112.95 kg/mm^2 to 127.72 kg/mm^2. The variation of Se concentration is continuous throughout the whole series,confirming the disordering substitution of Se for S and the existence of any possible transitional phases. Crystallographic parameters obtained from the series are a = 1. 123 33 nm to 1. 163 86 nm,b=1. 131 46 nm to 1. 178 53 nm,c=0. 383 93 nm to 0. 398 06 nm,D=4. 593 g/cm^2 to 5.996g/cm^3. V=0.48798nm＆3 to 0.54600nm^3. As may be seen from the above data, the higher the Se concentration,the bigger the crystallographic parameters.
