Calculation method for prolonging the service life of light yellow dyed cotton international grading standard

Abstract

The invention provides a calculation method for prolonging the service life of the international grading physical standard of light yellow dyed cotton. +b, S2, Rd 初 value or +b 初 Values ​​are used as Y values ​​and brought into the formula to calculate the Y values ​​corresponding to each future year. This Y value is the Rd value or +b value of each future year corresponding to each color grade of light yellow dyed cotton; S3, through future years The Rd value and +b value of the year are used to judge the international cotton grading standard for light yellow dyed cotton. The present invention formulates and summarizes the change law of the international cotton grading physical standard of light yellow dyed cotton, and can calculate the color grade of each year of the physical standard through the formula so as to use it more accurately and ensure the accuracy of the detection result; at the same time, the physical standard can be effectively Quantitative judgments can be made to avoid the waste of resources caused by one-time replacement, thereby reducing waste of resources and saving costs.

Description

technical field [0001] The invention relates to the technical field of entry-exit cotton detection, in particular to a calculation method for prolonging the service life of light yellow dyed cotton international classification physical standards. 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 i...

[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
