The values of the parameters х and K in the expression for the concentration dependence of the signal,reported by different authors for sensors of the same chemical composition and for the same gas,strongly differ.The reason is that the sensing layer parameters in the sensor vary with the method of its preparation.The highest sensitivity over a wide concentration range is exhibited by semiconductor sensors of different chemical compositions in the case of ozone.High sensitivity with respect to ozone is the most pronounced at low (0.1 ррm) and even lower concentrations.At 0.1 ррm,the sensitivity to О3 exceeds by approximately an order of magnitude those to NO2,ClO2,and Cl2.At 1 ppm and over,the sensitivities of sensors to ozone,nitrogen dioxide,and chlorine dioxide become comparable,as exemplified by the data for In2O3-based sensors.The In2O3- and ZnO-based sensors exhibit the lowest sensitivity to HCl.Semiconductor sensors can detect О3,NO2,СlО2,Сl2,and НСl gas impurities at the MPCw.z.level,and in the case of О3,NO2,and НСl,at the MPCd.a.level and below.

将浓度依赖性的信号用表达式表达.对于同样的化学成分和气体制作的传感器,不同的作者给出的表达式中的参数x和k的值相差很大.这是因为敏感的阶层参数会因为准备体系的不同而不尽相同.在一个宽泛的浓度范围内,在臭氧环境下一些不同的化学成分的半导体传感器显示出了最高的敏感性.这种臭氧环境下的高敏感性尤其会在低浓度（≤0.1ppm）中凸显.在0.1ppm的浓度下,传感器在臭氧中的敏感性大约超出了NO2,CLO2,CL2的.当浓度大于等于1 ppm时,传感器对臭氧、二氧化氮,氧化铝的敏感性变得可比较了（以In2O3为基础的传感器便是个例子）.以In2O3或者ZnO为基础的传感器对HCL最不敏感.半导体传感器可以侦测到MPCw.z.级别的不纯净的O3,NO2,CLO2,CL2和HCL气体.
我翻译睡着了囧.这连句连的.而且这专业的.虽然我ALEVEL读化学可是我还是很吃不消╮(╯_╰)╭
