摘　　要：随着科学技术的发展,工业生产对生产环境洁净度的要求越来越高。激光尘埃粒子计数器是一种典型的空气洁净测试仪器,用来测量空气中悬浮颗粒的数量和大小,为空气洁净度的评定提供依据。文章在Mie氏散射理论基础上,围绕尘埃粒子计数传感器的温度稳定性展开实验研究。With the development of science and technology,industrial production requires more and more high cleanliness of production environment.Laser dust particle counter is a typical instrument for measuring air cleanliness.It is used to measure the amount and size of suspended particles in the air and provide a basis for the evaluation of air cleanliness.Based on the theory of Mie scattering,the temperature stability of the dust particle counting sensor was studied experimentally.

关 键 词：粒子计数器 洁净度 Mie氏散射 温度稳定性
