Peach fruit easily soften and have a short storage time at normal temperature. In this study, peach fruit （Prunus persica sieb et Zucc cv. Yingqing） were picked and stored at 25 and 4℃ to investigate the senescence in correlation with Ca^2＋- ATPase activity of microsomal membrane and lipid peroxidation during ripening and senescence. In comparison with that stored at 25~C, the fruit stored at 4℃ exhibited a higher flesh firmness, lower respiration rate, and generated the late bigger peak value of Ca^2＋-ATPase activity as well as maintained the higher activity of the enzyme. Meanwhile, the lower levels of super oxygen radical （O2^-.） production and content of malondialdehyde （MDA）, a product of membrane lipid peroxidation were observed. Sodium orthovanadate （SO） and erythrosin B （EB）, as Ca^2＋-ATPase inhibitors, could stimulate the respiration rate. The results suggested that the slower senescence rate of peach fruit was closely related to the higher peak value and longer duration of Ca^2＋-ATPase activity in microsomal membrane, with the slighter membrane lipid peroxidation and lower O2^-. production rate.

TWo complexes Ni(PAP)Cl2, Ni(PAP)2Cl2 were synthesized and characterized with IR. The IR data show that Ni(II) in Ni(PAP)2Cl2 is octahedral Structure and the electron donor atoms 2Cl, ZP and 2N are in trans position. The molecular structure of Ni(PAP)Cl2 shows that center nickel atom has square-planar configuration. All donor atoms. nickel atom and pyridine cycle are located almost in the same plane. Both the two complexes are of good catalytic activity for carboxylation of ethanol.

基层治理是国家治理体系的基石。党的十九大以来,我国基层治理逐渐由“体制构建”向“体系构建”转变,关注基层治理体系中核心要素对体系稳定、持续增效的维系机理,已经成为深化基层治理研究、彰显中国特色社会主义制度优势的理论命题。在此背景下,以“动力激发、动力梗阻、动力转向”为进路,探讨基层党建、基层公共服务与技术治理对于巩固基层治理体系稳定性的逻辑关系,不仅有利于创新基层治理研究视角,而且有利于整合治理资源、激发整体性动力。

We analyze the magnetic configurations of three super active regions, NOAA 10484, 10486 and 10488, observed by the Huairou Multi-Channel Solar Telescope (MCST) from 2003 October 18 to November 4. Many energetic phenomena, such as flares (including a X-28 flare) and coronal mass ejections (CMEs), occurred during this period. We think that strong shear and fast emergence of magnetic flux are the main causes of these events. The question is also of great interest why these dramatic eruptions occurred so close together in the descending phase of the solar cycle.
