摘　　要：激光尘埃粒子计数器的性能发生变化主要是因为温度参量的改变,而温度对计数器的影响,主要是对计数器的光源和电路元件产生影响。文中的实验主要从两个方面展开,即分别对激光光源、计数传感器电路板改变温度以观察其粒子浓度示值误差、分辨率等指标的变化情况。The performance of laser dust particle counter is mainly due to the change of temperature parameters and the influence of temperature on the counter is mainly on the light source and circuit elements of the counter.The experiment in this article was divided into two aspects.The laser light source and counting sensor circuit board were changed to observe the change of the two indexes of particle concentration indication error and resolution.
