查询词典 clusters

The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...

用MS-Xα方法研究了Fe8原子簇（具有D6h对称）和Fe15原子簇的电子结构，结果表明：（1）两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同；（2）两类原子簇中的电荷分布不是均匀的，电荷倾向于从外围原子向内部原子上转移，并且被转移电子的自旋方向与原子簇的对称性质密切相关。

The determinations of the absolute magnitude and the kinematicparameters of RR Lyrae stars, their effects on the estimations of thedistances and the ages of the globular clusters, and the comparisonsbetween the results and ones from other indicators of distances arereviewed.

Forexample, the absolute magnitude of RR Lyrae stars determined from thedirect and indirect measurement methods splits into fainter and brightervalues, the distance modulus of Large Magellanic Cloud and theestimate of the ages of Globular Clusters based on the RR Lyrae starsand the other indicators of distances are not fully coincided.

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.
