Japonica. Brief speculation on the evolutionary trend of the seed-coat micromorphological features of the genus Kadsura is discussed.Cladistic principles and methods have been employed in this study. The morphological characters have been polarized for phylogenetic analysis. Cladograms have been gotten with the related genus Illicium as the outgroup. As a result, a new system of the genus Kadsura has been reconstructed.

First, a model of transformer has been built and analysed to formulate the expression of pulse on the load capacitor, which can demonstrate the influence of major parameters of transfomer on the charging time and efficiency of energy-transmitting. The influence of output pulse when the resistor of circuit is being took into account also has been analysed by the means of circuit simulation and approximate solution of circuit equation. The efficiency of energy-transmitting under dual nonresonant condition has been analysed and the parameters of transformer has been decided.

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.
