Calculation method for prolonging stained cotton international classification material object standard service life

Abstract

The invention provides a calculation method for prolonging stained cotton international classification material object standard service life. The method comprises the following steps: S1, determiningreflectivity Rd and yellow depth + b of the stained cotton international classification material object standard of the first year; S2, substituting the Rd initial value or the + b initial value as aY value into a formula to calculate a Y value corresponding to each future year, wherein the Y value is Rd value or + b value of each future year corresponding to each color characteristic grade of the stained cotton; and S3, judging whether the stained cotton international classification material object standard is used continuously according to Rd value and + b value of each year in the future.According to the invention, the change rule of the international cotton classification material object standard of the stained cotton is summarized in a formula mode, and the color feature grade of each year of the material object standard can be calculated through the formula, so that the material object standard can be used more accurately, and the detection result is ensured to be accurate; andmeanwhile, the effectiveness of the real object standard can be quantitatively judged, and the resource waste caused by one-time complete replacement is avoided, so that the resource waste is reduced, and the expenditure is saved.

Description

technical field [0001] The invention relates to the technical field of entry-exit cotton detection, in particular to a calculation method for extending the service life of the international grading physical standard of stained cotton. Background technique [0002] The general physical standards for international cotton grading are valid for one year, and all of them will be replaced after one year. to serious losses. [0003] In addition, there are great differences in the temperature and humidity of the cotton grade laboratories distributed in various parts of my country. Each laboratory puts the standard material in the natural environment. Different environmental conditions will inevitably cause the standard material to change in different degrees. Changes in the degree will inevitably bring about inconsistencies in the test results of different laboratories. Over the years, with the expansion of the scope of my country's cotton trade, it is very common for inspection an...

[0003] In addition, there are great differences in the temperature and humidity of the cotton grade laboratories distributed in various parts of my country. Each laboratory puts the standard material in the natural environment. Different environmental conditions will inevitably cause the standard material to change in different degrees. Changes in the degree will inevitably bring about inconsistencies in the test results of different laboratories

Over the years, with the expansion of the scope of my country's cotton trade, it is very common for inspection and quarantine agencies in different regions to have inconsistent grade inspection results for the same batch of imported cotton, which has caused objections from both domestic and foreign trade parties, resulting in trade disputes. Inspection and quarantine agencies The impartiality and accuracy of the
