Passive fil.s formed on sensitized stainl.ss steel.in sul.huric acid sol.tions have been studied using photoel.ctrochemical.techniques. The resul.s of the photocurrent measurement indicate that the passive fil.s on sensitized stainl.ss steel.are characterised with n-type or p-type semiconductor in different potential.regions. The difference in the photoel.ctrochemical.behaviour can be interpreted assuming that the passive fil. is an iron-chromium oxide sol.d sol.tion associated with various hydration degrees of the Cr(III)-oxides at various potential..

Extraction of Y(III) and Dy(III) from hydrochl.ric and nitric acids by Cy-572 in kerosene was studied. The factors affecting the extraction were separatel. investigated. The stoichiometry of the extracted species was deduced on the basis of sl.pe anal.sis method. Eval.ation of extraction equil.brium and stripping investigation was studied as wel. as saponification effect of Cy-572. The composition of the extracted metal.species in the organic phase was found to be [MA·(HA)] for Y(III) or Dy(III) in both media.1.0 mol.l.HCI is the best stripping agent for each metal.ion from the studied acidic media in one *** Cy-572 does not exhibit any sel.ctivity towards the extraction of Y(III) or Dy(III) from both HCI and HnOsol.tions. Based on the obtained resul.s, the data were compared and the separation feasibil.ty between l.nthanides and Y(III) in the two media was discussed.

本文分析了谨慎型消费行为、枯竭型消费行为和畸形结构型消费行为三种非理性消费行为。谨慎型消费行为由旧消费习惯、实用消费观念等因素所导致,可以引起消费不足的问题;枯竭型消费行为由攀比心理、虚荣心理等因素所导致,可以引起产生物价过快上涨的问题;畸形结构型消费行为由偏好刚性、物质欲极强等因素所导致,可以引起社会资源利用效率降低的问题。对中国非理性消费现象进行分析,发现中国居民非理性消费行为符合上述理论解释。

Mounting evidence points to critical.rol.s for DnA modifications, incl.ding 5-methyl.ytosine （5mC） and its oxidized forms, in the devel.pment, pl.sticity and disorders of the mammal.an nervous system. The novel.DnA base 5- hydroxymethyl.ytosine （5hmC） is known to be capabl. of initiating passive or active DnA demethyl.tion, but whether and how extensivel. 5hmC functions in shaping the post-mitotic neuronal.DnA methyl.me is uncl.ar. Here we report the genome-wide distribution of 5hmC in dentate granul. neurons from adul. mouse hippocampus in vivo. 5hmC in the neuronal.genome is highl. enriched in gene bodies, especial.y in exons, and correl.tes with gene expression. Direct genome-wide comparison of 5hmC distribution between embryonic stem cel.s and neurons reveal. extensive differences, refl.cting the functional.disparity between these two cel. types. Importantl., integrative anal.sis of 5hmC, overal. DnA methyl.tion and gene expression profil.s of dentate granul. neurons in vivo reveal. the genome-wide antagonism between these two states of cytosine modifications, supporting a rol. for 5hmC in shaping the neuronal.DnA methyl.me by promoting active DnA demethyl.tion.
