目的 通过对高铁列车车厢物体物体表面消毒效果的现场实验和评价，为高铁列车车厢物体表面消毒剂的选择提供依据。方法 采用现场消毒试验方法评价消毒效果。运用SAS软件进行数据分析，率的比较采用t检验和方差分析，均以P<0.05为差异有统计学意义。结果 含氯消毒剂、乙醇类消毒剂、过氧乙酸消毒剂、二氧化氯消毒剂、二溴海因消毒剂、复合季铵盐消毒剂对高铁列车车厢物体表面消毒效果均符合要求，且对厕所门把手、座椅扶手、马桶按钮、小桌板、垃圾桶盖板及饮水机按钮表面自然菌杀灭对数值均>2.00;6种消毒剂自然菌杀灭率差异无统计学意义(P>0.05)。结论 该6种消毒剂对高铁列车车厢物体表面自然菌均具有较好的消毒效果，但实践中仍需综合考量区分使用。

Objective To conduct on-site test and evaluation on the disinfection effect of high-speed train carriage surfaces, so as to provide a basis for selecting disinfectants for high-speed train carriage surfaces. Methods The on-site disinfection test was conducted to evaluate the disinfection effect.The SAS software was used for data analysis. The rates were compared using t test and variance analysis, and all were statistically significant based on P<0.05. Results Chloride disinfection agent, ethanol disinfection agent, peroxide disinfection agent, chlorine dioxide disinfection agent, diptive disinfection agent, composite ammonium salt disinfection agent met the requirements of the surface disinfection effect of high-speed train carriage objects. The killing log value of natural bacteria of the surface of the toilet doorhandle, seat armrests, toilet buttons, small table boards, trash cans and water dispenser buttons were all>2.00. The natural bacteria kill rates of six disinfectants were not statistically significant(P> 0.05). Conclusion The six disinfectants all have a good disinfection effect on the surface of the high-speed train carriage, but it still needs to be comprehensively considered in practice to distinguish them.
