    摘要： Disclosed herein is a forged seal imprint checking method which includes a step ST-101 of generating a reference seal imprint from a genuine seal (ST-110) and a step ST-121 of comparing a compared seal imprints with the reference seal imprint to calculate characteristic values of the compared seal imprint with respect to the reference seal imprint (ST-140). According to experimental results, forged seal imprints obtained by seals forged by etching a zinc plate or a resin plate can be recognized and forged seal imprints generated by seals forged through computer copy can be also recognized. Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.

    摘要： A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.
