【摘要】 吸收型气体传感器的结构决定气体传感器的灵敏度和吸收效果。根据C2H2气体的光谱吸收特性,设计了一种简易的测试C2H2气体吸收强度的传感器结构。基于Gaussian03软件计算C2H2气体分子的振动强度,从分子能级角度阐述了吸收型气体传感器在近红外光区选择性光谱吸收的特点。同时通过实验加以验证,对比了理论计算与实验结论。更多还原

【Abstract】 Structure of absorption-type gas sensor determines the sensitivity,as well as the effect of absorption.According to the characters of spectral absorption about acetylene,a simple testing sensor structure is designed for absorption intensity of acetylene.Based on Gaussian03,vibration intensityof acetylene molecule is calculated.From molecular level,we explain the characters of spectral selective absorption near infrared region.Meanwhile,it is to verify the conclusion through experiment,compare with theoretical calculation and experimental conclusion.更多还原
