摘要
为了解旅客运输机座舱卫生学现状和制定其卫生标准提供科学依据，１９９４年对国内主要的６种旅客运输机型（Ｂ７３７、Ｂ７５７、Ｂ７６７、ＭＤ８２、Ａ３００和Ｙ７）的驾驶舱和客舱的前、中、后位开展了座舱卫生学调查。结果表明，平均温度２２．９℃、湿度０．８６ｋＰａ、风速０．１３ｍ／ｓ、ＣＯ浓度１．８０ｍｇ／ｍ￣３、ＣＯ＿２浓度０．１５ｋＰａ、空气细菌总数１４３５ｃｆｕ／ｍ￣３、舱内照明２２１lｘ、压力８５．０ｋＰａ噪声７８．３ｄＢ（Ａ），基本能满足人体健康、保证空勤人员的工作效率和旅客舒适性的要求。调查还发现，座舱卫生随舱位和机型而异．
In order to evaluate the hygienic envirinmental factors and obtain data for draft-ing hygienic standards of cabin, a hygienic investigation of passenger airplane cabin was car-ried out.Dry-bulb temperature,relative humidity,air flow,concentration of Carbon monoxide(C_(CO_2)) and carbon dioxide(C_(CO)) and total bacteria number in the air(TBNA),noise lighting and cabin air pressure were investigated at pilot,s,forward, middle and rear cabin in six types of airplanes(B737,B757,B767,MD82, Air Bus 300, Y7) respectively.The data were analyzed by SYSTAT software package.The average values of the indices were :dry- bulb temperature-23℃, relative humidity-0. 86 kPa,air flow-0. 13 m/s,C_(CO)-1.80 mg/m￣3,C_(CO_2)-0.15 kPa,TBNA-1 435 cfu/m3,noise-78 dB(A),illumi-nation-221 Lux and pressure duing level cruise was 85.0 kPa,TBNA was lower and illu-mination was brighter in pilot,s cabin than that in the passenger's cabin(P<0. 05).The in-dices vary according to aircraft types.These indices were not significatly different at different sites of the passenger cabin. The observed indices in the cabin basically meet the environmen-tal hygienic requirements for protecting aircrew and paxsenger's health and ensuring the air-crew's work efficiency.
