针对目前消光材料实验室动态测试的现状和不足, 提出了基于单光路实现生物材料紫外、红外复合消光性能的测试装置和方法。设计和制作了生物材料紫外、红外复合消光性能的测试装置, 利用上述装置测试了真菌LZ0926孢子, 得到了烟幕箱自制生物材料烟幕的紫外、红外波段平均透过率及质量浓度分别为29.597%、14.514%、0.389 g/m3, 通过数据处理系统得到了生物材料紫外、红外波段平均质量消光系数分别为0.794 75 m2/g, 1.241 59 m2/g。实验结果表明: 该装置成功地利用单光路实现了生物材料的紫外、红外波段的复合消光性能测试, 进一步丰富了生物材料多波段消光性能的测试手段。

Aiming at current conditions and shortages of laboratory dynamic experiment of extinction materials, test device and method, which was used to test composite extinction performance of biological materials in ultraviolet and infrared band, was presented based on single optical path. The device mentioned above was designed and made, transmittance of ultraviolet and infrared band, and mass concentration of self-made biological materials smoke in the smoke box were respectively 29.597%, 14.514%, and 0.389 g/m3. Average mass extinction coefficient of biological material in ultraviolet and infrared band were respectively 0.794 75 m2/g, 1.241 59 m2/g based on data processing system. Experimental result shows that the designed device is used to test composite extinction performance of biological materials in ultraviolet and infrared band based on single optical path successfully, and enriches test methods of multiband extinction performance of biological materials further.
