在发射光谱分析中,元素谱线的发射强度常以感光板上谱线的黑度来度量。为了实现含量直读及测量自动化,我们根据光谱定量关系式推导出与含量 C 成正比的反对数标尺。在数学模拟的基础上,实现了电路上的模拟。设计了具有黑度自动保持、相对强度与绝对强度转换、工作曲线的校直、样品含量直读、数字显示、自动打印、温度控制的光电译谱仪。
In emission spectroscopy, the emission intensity of the elemental spectrum is often measured as the darkness of the spectral line on the plate. In order to achieve direct reading and measurement automation, we derive an inverse logarithm proportional to the content C based on the spectral quantitative relationship. On the basis of mathematical simulation, the simulation on the circuit is realized. The design of a photoelectric spectrograph with automatic maintenance of blackness, conversion of relative intensity and absolute intensity, calibration of work curve, direct reading of sample content, digital display, automatic printing and temperature control.
