  摘要：

  研究了N,N-二溴和二氯苯磺酰胺（DBBS和DCBS）以及N,N-二氯氨基甲酸酯（DCU）与二烯的反应。DBBS或DCBS与1,5-己二烯、1,4-戊二烯和1,4-二苯基-1,3-丁二烯的反应导致了环状加成，产生了一定程度的吡咯烷衍生物，并伴随有开链加合物，而DCU则没有形成环状加合物，仅生成开链加合物的混合物。N,N-二卤代胺与1,4-环己二烯的反应也生成了非环状加合物。

• Method of incorporating brominated compounds as additives to expanded polystyrene molded patterns for use in lost foam aluminum casting

  A process including topically applying a finely divided powder onto a plurality of polystyrene beads. The finely divided powder includes brominated compounds including a brominated alkane having at least one substituent aromatic group. The polystyrene beads are pre-expanded with the topically applied brominated compounds and a molded pattern is formed from the pre-expanded polystyrene beads. A lost foam casting mold is formed with the molded pattern. Molten metal is poured into the lost foam casting mold and onto the molded pattern to depolymerize the polystyrene beads with the topically applied brominated compounds.

  一种工艺，包括在多个聚苯乙烯珠子上局部涂抹细粉。精细粉末包括溴化化合物，其中溴化烷烃具有至少一个取代芳香基团。聚苯乙烯珠子用局部施用的溴化化合物预膨化，并由预膨化的聚苯乙烯珠子形成模塑图案。用模塑图案形成消失模铸造模具。将熔融金属倒入消失模铸造模具并浇注到成型图案上，使聚苯乙烯珠与局部应用的溴化化合物发生解聚。

  As the Okinawa Trough is a back-are basin in early spreading, modern submarine hydrothermal activity and minerallization have many characteristics which have aroused wide attention. Up to now three well-known hydrothermal venting areas are all located in the middle part of the trough, During two cruise investigations to map and sample the seafloor numbers of Calyptogena sp, shells were dredged at two sites in the northern trough with comparatively thicker crust and numerous submarine volcanoes. Based on the fact that Calyptogena sp, is only observed around the hydrothermal vents and lives on hydrothermal activities, it is predicted that there is the possibility of modern hydrothermal activities in the northern part of the trough. In this note, the shell is carefully characterized and the sample locations with possible hydrothermal activity are given. it Is pointed out that the research of biogenic fossils to trace hydrothermal activity changes in venting time, strength fluctuations, evolution In chemical compositions and so on should be stressed in the future in addition to the study of the ecological characteristics of hydrothermal organisms.
