目的 在动物吸入染毒实验的毒理学研究中，对液体农药气溶胶系统进行实验研究和探讨。方法建立气溶胶发生气路系统，通过测量喷雾压力、流量、浓度，确定喷雾器喷嘴结构和稀释系统结构。结果喷雾压力在2～3个大气压时，3个喷嘴的喷雾器喷出的流量为13．67～18．67L/min，气溶胶浓度将近10000mg／m^3；1个喷嘴的喷雾器喷出的流量为10．67～15．50L/min，气溶胶浓度将近5000mg／m^3。结论按照染毒实验要求，动物吸入气体流量为5～lOL/min，毒物浓度为10～1000mg／m^3，故将喷雾器喷嘴数确定为1个，稀释系统采用两级稀释，稀释比在500～5之间，确定出毒物气溶胶发生系统的设计方案。
Objective A laboratory method of aerosol generation is studied for animal inhalation toxicity experiment. Method\ Through the atomization of solution and suspensions with compressed air used to generate aerosol, air pressure, flow rate and aerosol concentration are measured. Results\ When air pressure is 2-3 atm, flow rate of three\|hole\|nebulizer is 13 67-18 67 L/min, aerosol concentration is about 10000 mg/m 3, and flow rate of one\|hole\|nebulizer is 10 67-15 50 L/min, aerosol concentration is about 5000 mg/m 3. Conclusion\ According to the given condition, one\|hole\|nebulizer and two diluters are chosen for the purpose.\;
