Calculation method for prolonging the service life of the international grading physical standard for stained cotton

Abstract

The invention provides a calculation method for prolonging the service life of the international cotton grading standard for stained cotton. The method includes: S1, determining the reflectance Rd and yellow depth + b of the international cotton grading standard for stained cotton in the first year , S2, Rd 初 value or +b 初 Values ​​are used as the Y value and brought into the formula to calculate the Y value corresponding to each future year. The Y value is the Rd value or +b value of each future year corresponding to the various color grades of stained cotton; S3, through the future years The Rd value and +b value to judge the stained cotton category continue to be used in the International Cotton Classification Physical Standard. The present invention formulates and summarizes the change rules of the international cotton grading physical standards for stained cotton, and can calculate the color grades of each year of the physical standards through formulas so as to use them more accurately and ensure accurate detection results; at the same time, it can check the effectiveness of the physical standards Quantitative judgment is made to avoid the waste of resources caused by all replacements at one time, thereby reducing waste of resources and saving expenses.

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...

[0002] The general physical standards for international cotton grading are valid for one year, and all of them will be replaced after one year of use. severe loss

[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
