开放实验设计:利用地基DOAS技术测量大气中NO_(2)浓度

Open Experiment Design:Measurement of Atmospheric NO_(2) Density by Using Ground-based DOAS

光电类开放实验是学生在熟悉一定专业知识基础上,利用光电检测技术及系统对光学量和非光物理量进行测量的实验.设计“利用地基DOAS技术测量大气中NO_(2)浓度”开放实验,目的是使学生掌握和了解差分吸收光谱技术的基本原理和操作,通过光谱仪性能测试增加学生对光电器件的了解,最终学会太阳散射光谱的测量和分析.该实验可以增加学生的知识储备,培养学生的实践和独立解决问题能力.

The open experiment of optoelectronics is an experiment in which students use photoelectric detection technology and systems to measure optical and non-optical physical quantities on the basis of familiarization with certain professional knowledge.The open experiment of“Measurement of atmospheric NO_(2)density by using ground-based DOAS”is designed to enable students to master and understand the basic principle and operation of differential absorption spectroscopy technology,increase students′understanding of photoelectric devices through spectrometer performance test,and finally learn the measurement and analysis of solar scattering spectrum.The experiment can increase students′knowledge reserve,and cultivate thepractice ability and independent problem-solvingability.
