最小二乘法在尘埃粒子计数器中的应用

摘要

分析了导致尘埃粒子计数器标定过程非常复杂的原因，提出将最小二乘法用于尘埃粒子计数器标定过程中的方法，有利于提高仪器标定的一致性并降低劳动强度。文中给出了用最小二乘法对国产激光尘埃粒子计数器进行标定的实验结果。%The reasons that lead to the complication in the process of demarcating the airborne particle counter is anal-ysed in this paper. And the Least Square Method is introduced, which can increase effectively the consistency of the in-strument demarcation and decrease the labor intensity. Experimental results calculated by the Least Square Method hasbeen performed with laser airborne particle counter.
