is studied.Based on the theory of surface adsorption
the microcosmic parameter n which represent humidity sensitive properties is obtained.The humidity sensitive parameter n of the material with better humidity sensitive properties should be near to 0.5.The experimental results show that humidity-sensitive material with lower resistance at lower humidity and with proper humidity sensitivity can be made by appropriate liquid-doped LiZnVO

.The parameter of resistance-humidity properties derived from theoretical calculation can well agree with the experimental results.
