光脉冲在不连续光波导中的传播

在时域内应用慢包近似（ＳＶＢＡ）的方法，对光波导内光波传输的时域计算做了简化．应用该方法计算了不连续光波导中光脉冲的传播，得到波导不连续处的传输情况．文中应用的计算方法可以大大节省计算机的内存，节省计算时间，是进行时域计算的一种行之有效的方法

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.

Studies on the reaction between Laccase ando-methoxyphenol by microcalorimetry

The reaction between Laccase ando-methoxyphenol have been studied by LKB-2107 batch microcalorimetry system. Thermodynamic parameters Δ _r H _m , ΔG _o , ΔG _T ^≠ and kinetic parameters (K _m ,k ₂) have been determined. The process of the reaction has been analyzed from changes in energy by using the transition state theory. Two methods for enhancing catalytic power of Laccase are proposed. The results shown that formation of an enzyme-substrate complex is “anticatalytic”. The enter and sole source of catalytic power is the stabilization of transition state; reactant-state interactions are by nature inhibitory and only waste catalytic power.
