不同灭蟑方法搭配使用对不同车型旅客列车灭蟑效果的研究

目的研究不同灭蟑方法的搭配使用对不同车型旅客列车的灭蟑效果,以找出高效、合理、科学、经济的灭蟑方案。方法对各新时速、25K型、25G型、22型的4个车底用A、B、C、D 4种灭蟑方案对应作业,用药激法调查作业前后蟑螂密度,计算杀灭率。结果新时速列车A方案的平均杀灭率为72.9%,B方案的平均杀灭率为96.3%,C方案的平均杀灭率为100%,D方案的平均杀灭率为100%,即灭蟑效果D=C>B>A;25K型列车A方案的平均杀灭率为82.2%,B方案的平均杀灭率为86.7%,C方案的平均杀灭率为88.3%,D方案的平均杀灭率为93.3%,即灭蟑效果D>C>B>A;25G型列车A方案的平均杀灭率为72.9%,B方案的平均杀灭率为80.9%,C方案的平均杀灭率为89.3%,D方案的平均杀灭率为93.9%,即灭蟑效果D>C>B>A;22型列车A方案的平均杀灭率为46.7%,B方案的平均杀灭率为71.4%,C方案的平均杀灭率为58.3%,D方案的平均杀灭率为78.8%,即灭蟑效果D>B>C>A。结论不管是哪种车型,D方案都起到最好效果,A方案相对其他方案都是最差效果,但从合理、科学、经济的角度考虑对新时速列车使用,C方案灭蟑较佳,25K型和25G型都是使用D方案最佳,其次是C和B,22型最好是D方案,而B方案优于C方案。

Efficacy of different methods for killing cockroach on different type passenger train

Objective To study the efficacy of different method for killing cockroach on the different type passenger train and to find out efficient,reasonable,scientific,economic method for killing cockroach. Methods Using A,B,C,D four kinds of method for killing cockroach to each xingshisu,25K,25G,22 type,using chemical insecticides to investigate the density of cockroaches and counting the killing rates. Results The average killing rates of xingshisu was 72.9%,the B was 96.3%,the C was 100%,the D was 100%,that was say the efficacy of killing cockroach were D=C>B>A;the average killing rates of 25K was 82.2%,the B was 86.7%,the C was 88.3%,the D was 93.3%,that was say the efficacy of killing cockroach were D>C>B>A;the average killing rates of 25G was 72.9%,the B was 80.9%,the C was 89.3%,the D was 93.9%,that was say the efficacy of killing cockroach were D>C>B>A;the average killing rates of 22 type was 46.7%,the B was 71.4%,the C was 58.3%,the D was 78.8%,that was say the efficacy of killing cockroach were D>B>C>A. Conclusion Whichever kind of passenger train,the project of D was the best method,the project of A was the badest method to other projects,but considering from reasonable,scientific,economic,the project of C was better than D to the xingshisu,the 25K type and 25G type using the project of D was the best,the next was C and B,for 22 type the project of D was the best,but the project of B was better than C.
