Description

Method for identifying ancient ceramic microscopic science air blister characteristic

Technical field

The present invention relates to ancient pottery and porcelain and identify the field, particularly a kind of porcelain glaze bubble microscopic features of utilizing are identified old china kilneye and the micro-scientific and technological bubble of the ancient pottery and porcelain in age, are applicable to and identify different kilneyes, the old china device of various years.

Background technology

Scientific and technological authentication method to ancient pottery and porcelain roughly is divided into two big classes at present: the first diminishes test, mainly comprise thermohtminescence dating method and pile neutron activation analysis, thermoluminescence can directly record the burning of pottery and make the age, also is the effective ways of generally acknowledging in the world.But it has significant disadvantages, the one, and thermoluminescent method is easy to be subjected to extraneous factor and disturbs, and pottery is by x-ray bombardment, contacted radiomaterial or at high temperature did experiment and just can't measure and identified that the porcelain burning makes the age; The 2nd, the test of thermoluminescence and neutron activation method all needs to take a sample from pottery, and therefore, above-mentioned two kinds of methods can only be made the usefulness of research in the laboratory, can't promote the use of in whole collection circle.It two is non-destructive testings, comprise that mainly energy dispersion X fluorescence power spectrum, proton excite X fluorescence power spectrum, synchrotron radiation X fluorescence power spectrum, these class methods generally are to utilize light that the kind and the quantity of the chemical element that contains in the antique pottery porcelain body glaze are carried out analytical test, the shortcoming of these class methods, the one, ancient pottery and porcelain is had destructiveness, the 2nd, measured object itself is by radiation pollution.Some mechanism of unit relates to bubble research in the recent period, but rests on the observation of use instrument stage substantially, belongs to the extension of naked eyes, information such as the regularity of distribution is not carried out systematic analysis as yet.

Summary of the invention

The purpose of this invention is to provide a kind of porcelain glaze bubble microscopic features of utilizing and identify the porcelain kilneye and the method for identifying ancient ceramic microscopic science air blister characteristic in age.This law can not only be made effective evaluation, has avoided existing science and technology to identify simultaneously and has diminished the problem of being identified porcelain.

The present invention finishes with the following method: the present invention is by setting up certain kilneye, certain age porcelain master pattern, set up porcelain model to be identified and identifying that differentiating three parts forms.

Set up certain kilneye age porcelain master pattern: ancient pottery and porcelain is burnt when making all has the strict process requirement owing to make aspects such as time, use fuel, atmosphere in raw material, prescription, burning, burning is made the bubble that is created in the process in the glaze and is all had certain stability at aspects such as form, distributed number, even use through what years, as long as porcelain does not have heavy wear, the feature of bubble is constant substantially.The progress that each pottery burns fabrication technique in epoch then can cause the variation of bubble feature, and this makes the different characteristics that change of epoch with regard to the bubble feature has been possessed because of burning.The present invention utilizes optical instrument that the bubble feature that exists in each age pottery glaze is carried out harmless fully observation, take a picture, calculate the bubble pattern characteristic statistic of a large amount of standard porcelain, the diameter mean value that comprises bubble, median, fractile, standard deviation, the distribution density of bubble and bubble standardization radial distribution function, and data are stored with the relevant database form, utilize above-mentioned statistic in the database to carry out the model parameter estimation of normal distribution type, set up statistical model, simultaneously by calculating the fourier spectrum of a large amount of standard porcelain bubbles, and data are stored with the relevant database form, the model parameter estimation of utilizing the fourier spectrum in the database to carry out normal distribution is set up the Fourier model of standard porcelain.On above-mentioned statistical model and Fourier model based, set up the master pattern of certain kilneye age porcelain.

Set up porcelain model to be identified: utilize optical instrument that porcelain glaze to be identified is amplified, absorb this porcelain glaze air entrapment distributed image with polarized light and high resolution CCD.Calculate the bubble pattern characteristic statistic that porcelain glaze bubble to be identified distributes, comprise distribution density, the bubble standardization radial distribution function of bubble diameter, median, fractile, standard deviation, bubble.Bubble pattern characteristic statistic according to porcelain to be identified carries out the estimation of normal distribution pattern shape parameter, sets up the statistical model of porcelain to be identified.According to the bubble diagram picture of the porcelain to be identified that collects,, analyze the Fourier model that data are set up porcelain to be identified according to fourier spectrum by the image Fourier analysis.On above-mentioned porcelain statistical model to be identified and Fourier model based, set up the model of porcelain to be identified.

Identify and differentiate: select target model in porcelain master pattern storehouse, compare with porcelain model to be identified, draw the probability of porcelain to be identified and standard porcelain similarity degree, make judgement.The present invention can identify the porcelain in ancient times of different kilneye various years effectively, and can not produce any damage to porcelain to be identified, has tangible economic benefit and social benefit.
