带堆焊层钢管焊接接头耐蚀性的电化学评定

采用电化学测试技术评价了低碳钢管管端内壁不锈钢焊条堆焊后再用相同焊条进行打底焊所得焊接接头（特别是焊接热影响区）的耐蚀性，选用两种高合金焊条M2、M6，并对堆焊金属进行热模拟试验，测定了模拟热影响区不同部位在3％NaCl介质中的阳极极化行为．结果表明，按新工艺焊接的接头代替普通碳钢焊接接头可有效地提高管道接头的使用寿命．两种焊条中，含Nb的M2耐蚀性比M6好，铌能够有效提高接头的耐均匀腐蚀、晶间腐蚀和点蚀能力，热影响区600～1000℃是高合金接头耐蚀性最薄弱的区域，建议采用超低碳含铌高合金焊条，以解决热影响区的腐蚀问题．

Synthesis of glucoside compounds of ferrocenyl phenols and their antianemic activity

Six glucoside compounds have been synthesized by means of phase-transfer catalytic method and deacetylation from the starting material ferrocene. Their structures have been confirmed by elementary analysis, IR,¹HNMR and MS. The antianemic activities of some compounds have also been tested. Results indicate that these glucoside compounds possess the antianemic activities and therefore, the further study is well worth making.

Studies on a series complexes of copper (II), zinc (II), cobalt (III) with Schiff base derived fromd-glucosamine and salicylaldehyde

Copper (II) zinc (II) cobalt (III) complexes with the Schiff base derived from salicylaldehyde andd-glucosamine were synthesized. These compounds abbreviated as SG, CuSG, ZnSG, CoSG were characterized by elemental analyses, IR, UV-Vis,¹H NMR and MS spectrum. ESR spectrum, magnetic susceptibility measured by Evans method for CuSG had also been done. It is suggested that the complexes in solution have pseudotetrahedral structure. It was found that SG would occur a photochemical reaction if a beach of 355 nm ultravisible light shone on its aqueous solution. The reaction was in further research.
