Calculation method for prolonging service life of light yellow stained international grading physical standard

Abstract

The invention provides a calculation method for prolonging service life of a light yellow stained international grading physical standard. The method comprises the following steps of step S1, determining the reflectivity Rd and the yellow depth +b of the first year of a light yellow stained international cotton grading physical standard; step S2, respectively taking an initial value of the Rd or an initial value of the +b as a Y value, and substituting the Y value into a formula to calculate a Y value corresponding to each year in the future, wherein the Y value is the Rd value or the +b valueof each future year corresponding to each color sign level of the light yellow stained; and step S3, judging that the light yellow stained international cotton grading physical standard continues tobe used through the Rd value and +b value of each year in the future. According to the calculation method for prolonging the service life of the light yellow stained international grading physical standard provided by the invention, the change rule of the light yellow stained international cotton grading physical standard is subjected to formulated summary, the color sign levels of all years of the physical standard can be calculated through the formula, so that the use is more accurate and an accurate detection result is ensured; and at the same time, the effectiveness of the physical standard can be quantitatively judged to avoid waste of resources caused by one-time all replacement, thereby reducing the waste of resources and saving the expenses.

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.

[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
