The main objective was to study the anticorrosion performance of poly（o-toluidine）/nano ZrO2/epoxy composite ***（o-toluidine）/nano ZrO2 composite was prepared by in situ polymerization of o-toluidine monomer in the presence of nano ZrO2 *** transformation infrared spectroscopy（FT-IR）,UV-visible spectroscopy（UV-vis）,X-ray diffraction（XRD）,Scanning electron microscopy（SEM）,and Thermogravimetric analysis（TGA） were used to characterize the composition and structure of the ***（o-toluidine）/nano ZrO2 composite was mixed with epoxy resin through a solution blending method and the three components poly（o-toluidine）/nano ZrO2/epoxy composite coating was coated onto the surface of steel sample by the brush coating *** anticorrosion performance of poly（o-toluidine）/nano ZrO2/epoxy composite coating on steel sample was studied by polarization curve and electrochemical impendence spectroscopy in 3.5% Na Cl solution as corrosion environment and also compared with that of poly（o-toluidine）/epoxy composite coating and pure epoxy *** was observed that the composite coating containing poly（otoluidine）/nano ZrO2 composite has got higher corrosion protection ability than that of poly（o-toluidine）.The electrochemical measurement results demonstrated that poly（o-toluidine） fillers improve the electrochemical anticorrosion performance of epoxy coating and the addition of nano ZrO2 particles increases the tortuosity of the diffusion pathway of corrosive substances.

A comparative study of electroacupuncture at Zhongliao （BL33） and other acupoints for overactive bladder symptoms

引用

Frontiers of Medicine 2017年第1期11卷 129-136页

作者： Likun Yang Yang Wang qian mo Zhishun Liu Department of Acupuncture Guang'anmen Hospital China Academy of Chinese Medical Sciences Beijing 100053 China Graduate College of Tianjin University of Traditional Chinese Medicine Tianjin 300193 China School of Acupuncture-moxibustion and Tuina Guiyang College of Traditional Chinese Medicine Guiyang 550025 China Department of Acupuncture the Second Affiliated Hospital of Guiyang College of Traditional Chinese Medicine Guiyang 550003 China

Electroacupuncture （EA） at Zhongliao （BL33） can improve the symptoms of overactive bladder （OAB）, such as urinary frequency, urgency, and incontinence. However, its performance compared with other acupoints remains unclear. This study investigated the effects of EA at BL33 with deep needling on rats with OAB by detecting urodynamics in eight groups： no intervention group, D-BL33 group （deep needling at BL33）, S-BL33 group （shallow needling at BL33）, non-acupoint group （needling at the non-acupoint next to BL33）, Weizhong （BL40） group, Sanyinjiao （SP6） group, Tongtian （BL7） group, and Hegu （LI4） group. Results revealed that EA at BL33 with deep needling, BL40, and SP6 prolonged the intercontraction interval （ICI） of rats with OAB （P= 0.001, P = 0.005, P = 0.046, respectively, post-treatment vs. post-modeling）. Furthermore, the change in ICI from post-modeling in the D-BL33 group was significantly greater than those of the no intervention and other EA groups （all P 〈 0.01）. Significantly shortened vesical micturition time （VMT） and elevated maximum detrusor pressure （MDP） were also observed in the D-BL33 group （P = 0.017 and P = 0.024, respectively, post-treatment vs. post-modeling）. However, no statistically significant differences in the changes of VMT and MDP from post- modeling were observed between D-BL33 and the other EA groups. In conclusion, EA at BL33 with deep needling may inhibit acetic-acid-induced OAB more effectively.

The title complex [CoL（H20）3]2·H2O （C26H46N4O21S4CO2）, where L = taurine-5- methyl-2-hydroxyisophthalaldehydes, has been synthesized and characterized by IR and X-ray diffraction analysis. The crystal of the complex belongs to the triclinic system, space group P1, with a = 11.197（4）, b = 13.309（5）, c = 14.486（5） ]A, a = 78.827（13）,β = 70.547（11）, γ = 81.058（13）°, Mr = 996.77, S = 1.08, V= 1987.2（13） A3, Z = 2, Dc = 1.666 g/cm3, F（000） = 1032,μ = 1.131 mm^-1, R = 0.0633 and wR = 0.1293. According to the structural analysis, the Co（ Ⅱ ） ion adopts a slightly distorted six-coordinated octahedral geometry. One N atom of the Schiff base of each molecule was hydrogenated to form hydrogen bond with O atom. Two coterminous molecules packed in one crystal water molecule are linked by intermolecular hydrogen bonds, thus generating an infinite chain constructed by hydrogen bonds.

Retention behaviour of carboxylic acid methyl esters in supercritical fluid chromatography

引用

Chinese Journal of Chemistry 1994年第2期12卷 129-137页

作者： SHEN, Yu-Feng WANG, Qing-Hai ZHU, Dao-qian ZHOU, Liang-mo Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian, Liaoning 116012, China Dalian Institute of Chemical Physics Chinese Academy of Sciences Dalian Liaoning 116012 China

The study on retention behavior in supercritical fluid chromatography (SFC) is necessary to understand the mechanism of the various interactions in SFC. The retention of SFC in carboxylic acid methyl ester/polymethylsiloxane/CO2 system was studied systematically and the retention behavior of this kind of compounds under various typical operation conditions was described using the method of an alternative unified theory of chromatographic retention. The results illustrated that expression: Ink.= a + b/T + cp + dp/T + ep2/T can be used to describe quantitatively the retention behavior of carboxylic acid methyl ester/polymethylsiloxane/CO2 system in the ranges of reduced density from 0.549 to 1.411. It was also found that the entropy of solute in stationary phase is dependent on the density of supercritical fluid (SF) under typical operating conditions of SFC.

本文通过分析美国1989-1992年和中国1996-1998年间的信贷挤压过程在金融和实体经济部门的表现,考察了银行体系在资本充足率约束下被迫进行资产负债表调整,以及这种调整对实体经济部门的影响。结果显示:银行体系在提高资本充足率的过程中,一般地会提高债券等低风险资产的比重,进而降低对实体经济的贷款供给;贷款供给的减少可能导致对银行信贷依赖程度较高的实体部门的收缩,并进而在短期内影响实体经济的总量增长。
