Colorless Emerald Transparency Of Grading Standards In Basic Theoretical Research

Because the jade its beautiful luster, the durable characteristic as well as deliver scarce enjoys people's favor, particularly along with the national economy level's enhancement, the jade profession flourishing as never before, the jade market found at everywhere in recent years, the jade business volume assumed year by year the trend of escalation. Expands unceasingly along with the jade market and consummates, the jade value question becomes puzzles the consumer the most important question, therefore is urgently needed must carry on the rank appraisal to the jade, with by standard jadeite market, and may instruct the consumer to expend.This paper uses the Fourier infrared spectroscope to carry on the experiment sample transparency the survey. The infrared spectroscope's principle of work is:The different material's member will absorb certain specific wave lengths the infrared beam, will thus form this molecular the infra-red absorption spectrum. When uses the transmission method carries on material the infrared spectrum test, spectrum chart y-coordinate namely for this material transmittance. Therefore, through the use infrared spectroscope, may very easily the jadeite transparency question quantification.This paper main research content is:Establishes the colorless jade transparency the mathematical model, and confirms "Jade Graduation National standards" with this model with Yunnan Province "Jade Accessories Quality scale Appraisal" about the colorless jade transparency graduation, regarding does not tally the part carries on the discussion, proposes author's individual viewpoint. The author first through to the glass thickness and the transparency survey, establishes the glass transparency and thickness mathematical relation model; Then carries on the transparency again to the massive colorless jade sample the survey and the micro enlargement observation, the metrical data will carry on the fitting with the mapping software; Finally in the synthesis glass experiment obtains the mathematical formula, will give the colorless jade transparency the formula, in the formula will include the jadeite accessories'thickness and the microstructure to the transparency the influence.This paper attempts the tradition only to depend in the jade graduation system which the sense organ establishes the colorless jade transparency hierarchy system, establishes mathematics modeling with the author to unify, thus increases hierarchy system's usability with to be advantageous operationally. Along with science's and technology's changing with each new day, believed that in the future will be more scientific in the jade hierarchy system, hopes the role which this article can play offers a few ordinary introductory remarks so that others may offer their valuable ideas, will provide a new mentality for the jade graduation work study.
