查询词典 appreciable

All are radioactive heavy metals; and only the first four (actinium, thorium, protactinium, and uranium) occur in nature in appreciable quantities. The other 11 are unstable and are produced only artificially.

这些元素都是具有放射性的重金属；仅前四个元素是在自然界中存在的，其余十一个都不稳定且均为人造的。

It is still needed to do some work to determine the deformation parameter β2 for light odd-odd nucleus, like 6Li and to calculate all reaction channels by means of CDCC code simultaneously. It is important to measure the exclusive angular distributions of breakup fragments.In theory, the coupling channel equations have been deduced from one-dimensional to multi-dimensional barrier tunneling. The couplings between the entrance channel and the other channels have appreciable effects on sub-barrier fusion cross section. Instead of single fusion barrier,these couplings lead to a distribution of fusion barrier Dfus.

描述了已有理论，从简单的一维势垒穿透模型出发，引入多维势垒穿透和耦合道模型，证明入射道相对运动与碰撞核各种自由度的耦合导致熔合势垒的劈裂，较低的势垒有利于垒下熔合截面增强；给出了从熔合激发函数抽取势垒分布及从背角准弹激发函数抽取势垒分布的理论依据，以及它们的优缺点。
