The topological structure of a new type of static synchronous compensator, which consists of traditional 12-pulse converter and a cascaded H-bridge, is presented. The purpose of designing such a topological structure, which integrates the concepts of multi-level, soft-switching and re-injection, is to reduce the voltage harmonic content at AC side and to solve dynamic voltage balance among the switches connected in series.

The S-PEU as well as H-PEU had a soft segment-rich surface as shown by ESCA study. The recalcification times for S-PEU and H-PEU increased 20% and 100%, respectively,as compared with that of ungrafted PEU.

ESCA及抗凝血性研究结果表明，不同位置接枝的PEU，其表面都有明显的聚醚链段富集。S－PEU抗凝血复钙时间只比未接枝者增长约20％，而H－PEU则增约一倍，比S－PEU增约60％。

By applying a Fan-Glicksberg type fixed point theorem for upper semicontinuous set-valued mappings with closed acyclic values and a maximum theorem,several existence theorems of weighted Nath-equilibria and Pareto equilibria for the constrained multiobjective games are proved in noncompact locally convex H-spaces.

A dye recycled photosensitization system has been designed. As a result of studies in the mechanism of electron transfer reaction of xanthene iodonium salt, it is proposed that the dye-recycled process consists of three-step reactions during the photosensitization: The oxidative fading product of dye is formed through electron transfer under irradiation; In the presence of H-donor, product changes into acidic leuco dye product; Product undergoes deprotonization under action of base to regenerate initial dye.

本文设计了染料循环再生的光敏反应体系，通过对占吨碘翁盐电子反应机制的深入研究，提出了占吨染料在光敏反应过程中的染料再生循环，它依次由三个反应过程组成：在光作用下，通过电子转移反应，产生染料氧化褪色体；在H给体存在下，通过H转移反应，使产物转化为染料酸式隐色体；在碱作用下，发生去质子反应，染料再生回复到染料的起始结构。

The whole production process was as follows: fresh strawberry fruits after the extirpation of sepal and rachisbranch steeped in 0.5 ‰ potassium permanganate solution for 20 h and then washed by clean water, then after 15 h gelatin treatment by compound zymin, the fruits were used for fermentation, and the indexes of the produced wine reached the standards of quality wine.
