Embodiment Construction
[0017] In conjunction with the accompanying drawings, the detailed description is as follows. What is described here is mainly an implementation method of a particle size measurement method based on two-dimensional Raman spectroscopy.
[0018] figure 1 A flow chart of a particle size measurement method based on two-dimensional Raman spectroscopy provided by the present invention is shown, which is described in detail as follows.
[0019] The particulate matter to be measured is barium nitrate Ba(NO 3 ) 2 .
[0020] figure 2 Shown, Ba(NO 3 ) 2 Two-dimensional Raman spectroscopy of particulate matter, Ba(NO 3 ) 2 Particulate matter has two characteristic Raman peaks, namely, peak A and peak B, and peak B is larger than peak A. Therefore, peak B is intercepted for two-dimensional Gaussian fitting analysis to obtain peak B The two-dimensional Gaussian function expression for extracting the half-peak width W of the spectral peak B. On this basis, according to the linear ...
