HIRFL-CSRm���向随机冷却——Palmer冷却研究

对拟在HIRFL CSRm���建造的纵向Palmer冷却进行了数值优化计算 ,得出了最佳带宽、最佳增益及最短冷却时间 ,并运用Fokker Planck方程进行了模拟 ,得到了动量散度分布函数在冷却过程中随时间的变化 ,从而为纵向冷却系统的具体设计和优化提供了重要的理论依据 .

The pontoniine shrimps (Crustacea : Decapoda : Palaemonidae) from Anambas and Natuna Islands, Indonesia, collected by Anambas Expedition, 2002

The present paper reports 8 pontoniine shrimp species, from Anambas and Natuna, Indonesia, i. e., Anchistus miersi (De Man, 1888), Conchodytes meleagrinae Peters, 1852, Hamodacotylus boschmai Holthuis, 1952, Jocaste japonica (Ortmann, 1890), Palaemonella pottsi (Borradaile, 1915), Periclimenes andamanensis Kemp, 1922, Periclimenes attenuatus Bruce, 1971, and Periclimenes grandis (Stimpson, 1860).

Rediscovery of the sea cucumber "Toxodora" pacifica Ohshima, 1915 (Echinodermata : Holothuroidea : Apodida)

The apodous holothurian species originally described by Ohshima ( 1915) as Toxodora pacifica has been rediscovered, and its known geographic range extended from Suruga Bay, Japan to the western side of the Yellow Sea, China. As the genus name Toxodora is no longer available, a new genus name, Neotoxodora Liao, Pawson, and Wei, is proposed. The type material of Neotoxodora pacifica is lost, and a Neotype is named for this species.

海北站周围3种外来物种入侵状况的初步研究

通过对海北生态系统定位站附近3种植物播娘蒿Descurainia sophia、荠菜Capsella bursa-pastoris、灰绿藜Chenopodium glaucum���分布情况的调查,初步分析了3种植物的扩散策略,并预测了其对高寒草甸生态系统潜在的影响.
