4Preparation and Properties of Zirconium Hydrideon the surface of MCM-41 Mesoporous Molecular Sieves显示文摘Zirconium monohydride bonded to the framework oxygen of MCM-41 surface was prepared by the reaction of tetraneopentyl zirconium with MCM-41 surface hydroxyl groups, followed by the hydrogenolysis of the resulted product. The surface hydride was characterized by using infrared spectroscopy, solid-state NMR, elemental analysis, gas-phase chromatography and chemical probing reaction. It was shown that this surface species is stable below 150 'C and can catalytically crack alkanes into methane and ethane at 100 .WANG Xu-xu1* * , FU Xian-zhi1, LEFEBVRE Frederic2 and BASSET Jean-Marie2(1.

5New Diterpenoid Alkaloids from Spiraea japonica var. Ovalifolia显示文摘Five new diterpenoid alkaloids, 19-O-deethylspiramine N (1), deacetylspiramine S (2), spiramidine A (3), spiramidine B (4) and deacetylspiramine F (5) were isolated from the aerial parts of Spireae japonica L. f. var. ovalifolia. Their structures were charaterized mainly based on spectral analysis.Guo Ying ZUO1,2, Hong Ping HE1, Xin HONG1, Wei Ming ZHU1, Yi Ming HU1, Xiao Sheng YANG1, 3, Xiao Jiang HAO1* 1Laboratory of Phytochemistry, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650204 2Kunming 43 Hospital, PLA, Kunming 650032 2001Chinese Chemical Letters2001,12,2:2
6Combined sensor noise-immunity显示文摘The paper presents statistical analysis of combined sensor noise-immunity while recording fluctuating tone against underwater dynamic noise background. The experimeatal data used for the analysis have been collected by a pair of four-component combined sensors centered at two depths, 150 and 300 m in deep water. Expressions for combined sensor signal- to-noise ratio (SNR) for cross-spectral levels of signal and noise for both wide and narrow frequency bands have been derived. A combined sensor gain has been introduced in terms of ordinary single-point coherence function between acoustic pressure and particle velocity in acoustic wave. The estimates obtained experimentally evidence that SNR for a combined sensor with multiplicative data processing may exceed SNR for a hydrophone-based sensor by 15 to 16 dB at most for the horizontal channel of the combined sensor, and by 30 dB at most for the vertical channel (when opposite energy flows of signal and noise compensate one another).Vladimir A.

18The comparison study of diagnostics of light filaments in air显示文摘Long plasma channels in air induced by femtosecond laser pulses are inves-tigated using three different methods, including the cross-section imaging, resistivity measuring and acoustic diagnostics. These methods are based on different properties of the light filaments. A comparison of the three diagnostics shows that the imaging method is the most precise one in studying the filaments distribution and evolution, that the sono-graphic method is the most convenient approach to detecting long plasma channels by detecting the acoustic wave generation, and that the resistivity measurement can only be applied for giving a rough estimate. The diagnostics of filaments allow us to choose ap-propriate detecting methods and provide further insight into the dynamic evolution of the light filaments in air.HAO Zuoqiang1, ZHANG Jie1, YU Jin2, ZHENG Zhiyuan1, YUAN Xiaohui1,3, ZHANG Zhe1, LI Yutong1, WANG Zhaohua1, LING Weijun1 & WEI Zhiyi11.
