YZ-B型槍榴煙霧殺蟲彈實彈射擊戰(zhàn)技指標觀察

摘要： 目的觀察YZ-B型煙霧殺蟲彈實彈射擊戰(zhàn)技指標,并研究槍榴煙霧殺蟲彈對害蟲的殺滅效果。方法采用模擬現(xiàn)場和現(xiàn)場相結(jié)合觀察該槍榴煙霧殺蟲彈對蚊、蠅、蟑螂的殺滅效果。結(jié)果4 s延期裝置實彈發(fā)射角度20°~45°發(fā)射距離為182.5~350 m,延期發(fā)煙設(shè)置3 s組、4 s組煙霧持續(xù)時間分別為(4.25±0.5)min、(4.0±0.5)min;槍榴煙霧殺蟲彈發(fā)射彈點燃發(fā)煙率3 s組為83%,4 s組為95%;掛籠法距煙霧彈落地點0~5 m、低于地面50 cm以下對淡色庫蚊、家蠅、德國小蠊的殺滅率大于95%;發(fā)煙后0.5 h野外蚊、蠅種群密度下降100%。結(jié)論槍榴煙霧殺蟲彈試驗結(jié)果達到設(shè)計要求,可以有效地殺滅蚊、蠅、蟑等害蟲。
ObjectiveTo observe the tactical target of YZ-B fogging shrapnel-gun equipment for controlling mosquitoes and flies.MethodsHaving experiment in mimic area and fields and observing the efficacy of fogging shrapnel-gun against mosquitoes,flies and cockroaches.ResultsWhen shrapnel-gun shot out in an angle of 20°～45°,the distance was 182.5～350 meters.There were two type of delay fogging machinery,3 s and 4 s.They could last for(4.25±0.5) min and(4.0±0.5) min.The type of 4 s was better than 3 s.The smoke rate were 83% for 3 s and 95% for 4 s.When the shrapnel-gun equipment was put above the ground for 0～5 m,if it was 50 cm above the ground,it could kill 95% Culex pipiens pallens,Musca domestica and Blattella germanica.The population of mosquito and flies declined to 100%.ConclusionYZ-B fogging shrapnel-gun equipment got an ideal effect against mosquitoes,flies and cockroaches.The experiment result achieved satisfying design request.
