摘要

摘要：空气动力学粒谱仪能够同时测量气溶胶粒子的空气动力学粒径和光学粒径。本文采用多道存储技术，结合大规模可编程逻辑芯片及高速大容量双端口内存芯片，设计了高速大容量气溶胶粒子分类计数存储器。主要特色是：单一脉冲计数器与特征信号分类计数器有机结合，存储容量高达65535道，每道可计数65535个，典型操作速度可达15nS，且线路简单。该存储器作为本研究所自行研发的空气动力学粒谱仪的关键存储部件，完全满足仪器连续、实时、在线监测对存储速度和容量的要求。

Abstract

Abstract: Aerodynamic particle sizer can measure the aerodynamic diameter and optic diameter of the aerosol particles simultaneously. Based on large-scale programmable logic chips and dual-port high-speed large-capacity memory chips

a high-speed and large-capacity aerosol particles classification count storage is designed using multi-channel storage technology. The device has the following main features: two combined functions of single pulse counter and characteristic signal classification counter

the storage capacity of up to 65535 channels and each can count to 65535

a typical operating speed of up to 15nS

and simple circuit. As a key storage component of the aerodynamic particle sizer developed by our institute

this storage satisfies the requirements on the speed and capacity requested by a continuous

real-time and on-line monitor.
