含邻酚结构化合物氧化反应中自由基的检测

用电子自旋共振技术研究了水溶液中邻苯二酚、ＤＯＰＡ和槲皮素等化合物与Ｏ２－反应中产生的活性自由基中间体，根据所观察别的ＥＳＲ谱的超精细结构常数可以推断它们都是邻半醌负离子基，在自旋捕获实验中发现无水乙腈中碱性条件下这些化合物与Ｏ２反应时会产生Ｏ２－，这表明在某些重要的生物抗氧化剂的抗氧化过程中，可能产生新的活性氧．

温度场对自蔓延高温合成致密化的影响

在自蔓延高温合成（SHS）致密化工艺中，准确确定施压滞后时间是工艺控制的关键．施压滞后时间的上限值一般是根据SHS过程的坯块表面温度与时间关系曲线获得，难以真实地反映坯块内的温度变化．作者以传热学理论为基础，针对SHS－准热等静压过程，建立了燃烧产物内的温度分布方程，并以此解释了最终产物内密度分布存在差异和形状变化的原因．     

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.

The electrical conductivity of H_2O at 0.21-4.18 GPa and 20 -350℃

The electrical conductivity of H2O in solid and liquid phases has been measured at 0.21-4.18 GPa and 20-350℃. The results indicate: ( i ) different phases of H2O in solid have different relations between electrical conductivity and temperature and pressure. The conductivity changes continuously with temperature, but discontinuously with the pressure between 2.11 and 2.58 GPa, which corresponds to the transforming pressure between ice (Ⅵ) and ice ( Ⅶ ) ; ( ii ) the con-ductivity of H2O in liquid all increases with temperature and pressure, but there are discontinuities at pressures between 0.57 and 0.9 GPa, and between 2.11 and 2.58 GPa, which are also consistent with the polymorph of ice (ice ( Ⅴ), ice (Ⅵ) and ice ( Ⅶ ) ) . This reflects that H2O in liquid at different pressures has quite different properties of electron chemistry. It is prob-ably the important reason that causes the layers with high electrical conductivity and low velocity in the earth's crust and upper mantle.
