The earliest Chinese ancient glasses before the West Han Dynasty (200 BC) from different regions are studied. The glass samples were unearthed from Hunan, Hubei, Yunnan, Sichuan, Guizhou, Guangdong and Xinjiang of china. The chemical composition of these glasses samples is analyzed by proton induced X-ray emission (PIXE) technique, energy dispersive X-ray fluorescence (EDXRF) method and inductively coupled plasma atomic emission spectrometry (ICP-AES). It is shown that the glass chemical compositions belong to barium-lead silicate BaO-PbO-SiO2, potash soda lime silicate K2O (Na2O)-CaO-SiO2 (K2O/Na2O>1), soda potash lime silicate Na2O (K2O)-CaO-SiO2 (K2O/Na2O2O-SiO2 glass systems, respectively. The origins of the earliest Chinese ancient glasses are discussed from the archaeological and historical points of view. These four types of Chinese ancient glasses were all made in Chinese territory using local raw materials. The glass preparation technology was related to the Chinese ancient bronze metallurgy and protoporcelain glaze technology. The glass technology relationship between the East and the West is analyzed at the same time.

Samples of the jade artifacts unearthed from the Liangzhu sites at Yuhang (Fanshan,Yaoshan, Huiguanshan and Tangshan) of Zhejiang province were described. The chemical composition, phase and jade structure of a hundred and more intact samples were analyzed by the non-destructive techniques of PIXE, XRD and laser Raman spectroscopy. Results showed that the minerals of the jade artifacts mostly belonged to tremolite and tremolite-actinolite. Relationship of the civilization development in the Neolithic age and the application of tremolite type mineral in jade artifacts was discussed. The contents of rare and trace elements in tremolite jade artfacts and in mineral samples were measured for the first time. The possible mineral sources of these tremolite type jade artifacts were discussed.

It is known that any strict tensor category （C, I） can determine a strict braided tensor category Z （ C）, the centre of C. When A is a finite Hopf algebra, Drinfel’d has proved that Z（AM） is equivalent to D（A）M as a braided tensor category, where AM is the left A-module category, and D （A） is the Drinfel’d double of A. This is the categorical interpretation of D （A）.Z（4M） is proved to be equivalent to the Yetter-Drinfel’ d module category AY D4 as a braided tensor category for any Hopf algebra A. Furthermore, for right A-comodule category MA , Z（MA） is proved to be equivalent to the Yetter-Drinfel’ d module category AY D4 as a braided tensor category. But, in the two cases, the Yetter-Drinfel’ d module category AY DA has different braided tensor structures.

The reaction mechanism of 3 chlorophenol with OH, H in aqueous solution was studied by transient technology. The 3 chlorophenol aqueous solutions have been saturated with air or N 2 previously. Under alkaline condition, the reaction of OH radical with 3 chlorophenol produces 3 chlorinated phenoxyl radical, with the absorption peaks at 400 nm and 417 nm. Under neutral condition, the reaction of OH radical with 3 chlorophenol produces OH adduct with the maximal absorption at about 340 nm. And in acid solution, the reaction of H with 3 chlorophenol produces H adduct with the maximal absorption at about 320 nm. 3 chlorophenol is compared with 4 and 2 chlorophenols from the free radical pathways. The results show that the positions of chlorine on the aromatic ring strongly influence the dehalogenation and degradation process.

Darboux transformation gives explicit soliton solutionsof nonlinear partial differential equations. Using numerical computation in each step of constructing Darboux transformation,one can get the graphs of the solitons ***(n 3) , this method greatly increases the speed and deduces the memory usage of computation comparing to the software for algebraic computation. A technical problem concerning floating overflow is discussed.
