Filing authentication processing method for calligraphy and painting works

InactiveCN104123657AThe certification conclusion is reliable and safeLower operating costsCommerceSensing by electromagnetic radiationSerial codeComputer science
The invention discloses a filing authentication processing method for calligraphy and painting works. Two-dimension code seals are printed on the calligraphy and painting works in advance, and two-dimension codes and anti-fake serial numbers which store corresponding relevant calligraphy and painting work information are stored in an authentication server; when authentication operation is required to be performed on current calligraphy and painting works to be authenticated in the circulation process of art works, the two-dimension codes of the current calligraphy and painting works are scanned and sampled to access to the authentication server; the authentication server calls two-dimension code seals of the current calligraphy and painting works and compares the two-dimension code seals with the pre-stored two-dimension code seals for identification, and relevant calligraphy and painting work information which corresponds to the current calligraphy and painting works is obtained; whether anti-fake serial numbers are consistent with the pre-stored anti-fake serial numbers in the authentication server or not is determined; if the anti-fake serial numbers are consistent with the pre-stored anti-fake serial numbers in the authentication server, the current calligraphy and painting works to be authenticated are determined to be genuine; otherwise, the current calligraphy and painting works to be authenticated are determined to be fake. By means of the filing authentication processing method for the calligraphy and painting works, a user can be helped to know the calligraphy and painting art works and authors and authenticate the calligraphy and painting art works.

Method for multi-tower parallel connected adsorption removal of polycyclic aromatic hydrocarbons in diesel oil

The invention relates to a method for multi-tower parallel connected adsorption removal of polycyclic aromatic hydrocarbons in diesel oil. According to the method, active carbon, an oxide or a metal modified material is used as an adsorbent; diesel oil is firstly pretreated for adsorption removal of trace impurities; the diesel oil with impurities removed is introduced into multi-tower parallel connected adsorption equipment for adsorption separation of polycyclic aromatic hydrocarbons in the diesel oil, and simultaneously a desorbent is introduced; and through periodical switching of feed and discharge valves, the adsorption towers alternately carry out adsorption-regeneration to realize semi-continuous operation of adsorption-regeneration, so as to obtain desorbent-containing refined diesel component and polycyclic aromatic hydrocarbon components. As boiling points of the desorbent and the diesel component are quite different, a rectifying tower can be utilized to realize separation and recycling of the desorbent, and the refined diesel and polycyclic aromatic hydrocarbons are obtained. The technology for multi-tower parallel connected adsorption removal of polycyclic aromatic hydrocarbons in diesel oil has characteristics of low operation temperature, low pressure and continuous operation. In addition, the adsorption technology has strong capability of removing polycyclic aromatic hydrocarbons in diesel oil, and removal rate of polycyclic aromatic hydrocarbons can reach 80%.
