摘　　要：为了研究温度对两种钒酸钇棱镜透射比的影响,采用理论计算与分析的方法,并通过实验验证,进行数据对比。结果表明:理论值与实验值符合,钒酸钇棱镜的温度稳定性好,温度对格兰.付科型钒酸钇棱镜的透射比比格兰.汤姆逊型钒酸钇棱镜透射比影响更小,这为钒酸钇棱镜在工程实验中的应用提供了重要的参考价值。To investigate the temperature effect upon transmissivity of the two YVO4 prisms, this study applies theoretical calculation and analysis, as well as experimental verification and comparison method. The result shows that the theoretical value is consistent with the experimental value and the temperature of YVO4 prism is stable. Temperature has less impact on Glan-Foucault prism than Glan-Tomson prism. This provides an important reference value to the applioation of YVO4 prism in engineering experiment.
