利用意大利Leg.aro实验室串列静电加速器提供的65 m.V^(13)C束流与122sn靶的熔合蒸发反应布居了^(131)Ba的高自旋态,并搭建了新的能级纲图.新的能级纲图由15条转动带组成,包括三对手征双重带,其中两对正宇称手征带为赝自旋-手征四重带.正负宇称手征带通过一系列增强的E1跃迁连接,表明它们之间存在八极关联.在低自旋区域搭建了一条新的转动带,通过一系列γ跃迁向νh1_(1/2)晕带退激.这种能级结构与摇摆带相似,但基于现有的实验证据还难以将它确认为摇摆带,不能排除其他集体激发机制,如γ振动的影响.

探究西藏玉曲河流域裸腹叶须鱼(Ptychobarbus kaznakovi)的游泳能力,可为珍稀鱼类资源保护及鱼道设计提供理论参考。以体长(BL)18~27 cm.裸腹叶须鱼为研究目标,在野外场景下分别测试其感应流速、临界游泳速度、突进游泳速度和持久游泳速度。结果表明:(1)裸腹叶须鱼的感应流速为(0.17±0.01)m.s,平均相对感应游泳速度为(0.78±0.07)BL/s;临界游泳速度为(0.92±0.16)m.s,平均相对临界游泳速度为(4.33±1.20)BL/s;平均突进游泳速度为(1.28±0.39)m.s,平均相对突进游泳速度为(5.81±1.81)BL/s;(2)流速(V)对裸腹叶须鱼的持续游泳时间(t)有显著性影响,持续游泳时间均随设定流速的递增而明显下降,耐力关系可拟合为:lg.=-5.30V+6.39,游泳速度(V_(s))、鱼道总长度(d)和鱼道内最大流速(V_(f.)关系式为:V_(f.=V_(s)-d×10^((5.3Vs-6.39));(3)裸腹叶须鱼的趋流率(P_(re))与流速(V)拟合关系式为:P_(re)=14.23V-2.51,得出95%裸腹叶须鱼的趋流速度为0.18 m.s;(4)以裸腹叶须鱼为主要过鱼目标时,建议鱼道进口的设计流速为0.9~1.3 m.s,进口的主流长度为2~4 m.鱼道出口流速不低于0.2 m.s,鱼道池室主流流速为0.2~0.8 m.s。结合鱼类在竖缝处的不同上溯模式和持久游泳速度,推荐池室主流长度最大应为5.5 m.竖缝处最大平均流速为1.1 m.s,鱼道长短隔板沿水流方向的最大间隔为0.4 m.研究结果可为玉曲河鱼道关键部位的长度设计和流速要求提供基础数据支撑。
