摘　　要：目的:观察累计使用时间超过1 000小时的紫外线灯照射强度变化。方法:将累计使用时间大于1 000小时的64只灯管设为试验组,然后随机选取累计使用时间小于1 000小时的7 4只灯管为对照组。在标准状态下即温度、湿度、电压符合要求并在紫外线检测仪中测量,分别记录每只灯管的累计使用时间及照射强度。结果:试验组与对照组的平均累计时间差异有统计学意义(t=16.877,P<0.001),试验组的累计使用时间明显长于对照组,2组资料具有可比性。2组平均照射强度及合格率比较差异无统计学意义(t=0.755,P>0.05;x^2=0.011,P>0.05),不能说明2组灯管照射强度及合格率有差别。结论:紫外线灯管累计使用时间大于1 000小时,不应作为更换灯管的依据。紫外线的照射强度才是判断灯管合格的标准,因此要求在标准状态下测量其强度。Objective： To observe the irradiation intensity change of ultraviolet lamp with accumulated use time more than 1000 hours. Methods： The irradiation intensity of 64 lamps with accumulated use time more than 1000 hours were measured while 74 lamps with accumulated use time less than 1000 hours were measures as the control group. Results： The accumulated use time of the experiment group was longer than that of the control group （t =16.877, P 〈 0.001）. The radiation intensity of the two groups had no significant difference （t =0.755, P 〈 0.05;Χ^2 =0.755, P 〉 0.05）. Conclusion： The accumulated use lime more than 1000 hours should not be used as the lamp change base. The irradiation intensity is the only standard to judge the lamp whether qualified.
