[0056] Implementation example: measurement of cohesion index and colloidal layer index on 40 coal samples
[0057] 1) In this example, a total of 40 coal samples were used, 35 samples were selected as calibration samples, and the remaining 5 samples were used as samples to be tested; As a reference value, as shown in Table 1; due to the large amount of data, some sample data are omitted here;
[0058] Table 1. Calibration sample composition
[0059]
[0060]
[0061] 2) Use the LIBS system to collect the spectral data of 35 calibration samples to obtain the spectral line intensity;
[0062] 3) Screen the spectral lines and use the PLS method to establish a calibration model:
[0063] a) According to the physical background, select the atomic wires and ionic wires of carbon, nitrogen, silicon, oxygen, and aluminum, as well as CN, C 2 Molecular line, get spectral line set 1;
[0064] b) Randomly remove 5 of the 35 calibration samples, and use the PLS method to establis...
