| 摘 要： | 针对粒度标定的准确度，在概率空间基础上，提出了尘埃粒子散射光信号幅度概率谱线和散射光信号度概率谱函数的概念，并对谱线在概率空间上的性质进行了研究。利用单分散粒子间的不相关性，将概率论运用于信号处理中，用全概率公式概括了尘埃粒子计数器信号传输的本质，建立了适用于处理尘埃粒子计数器信号的更完善的概率理论西式。文中给出了这一方法的理论分析及国产Y09激光尘埃粒子计数器的实验测试结果。 |

| Abstract: | A more reasonable particle counter model suitable for airborne particle counter is constructed in the probability space.The amplitude spectrum line and the amplitude spectrum function are proposed for the airborne particle scattering light signal,and their properties are studied in probability space.Based on the irrelevance of the single distributing particle group and the probability theory of signal processing model,the essence of this signal transformation is summarized in a total probability equation.Experimental study has been performed with Y09 laser airborne particle counter. |
| Keywords: | airborne particle counter probability distribution spectrum line total probability equation |
