查询词典 angular rotation

Taking advantage of gauge transformation and dipolar approximation, we qualitatively derive rotating Bose-Hubbard model.Then finite temperature phase boundary between superfluid phase and normal state in rotating Bose-Hubbard model is analytically derived by studying the stability of normal state in rotating bosonic optical lattice.We also analytically prove that as the function of rotation angular velocity the oscillation of critical hopping matrix directly follows the upper boundary of Hofstadter butterfly.

4通过做一个规范变换和偶极近似，定性地推导了旋转Bose-Hubbard模型，并且通过研究正常态不动点的稳定性推广了旋转Bose-Hubbard模型的零温相图到有限温度的情形；另外根据系统有效的能带宽度与旋转速度的关系(Hofstadter蝴蝶)，得到了系统的临界跃迁矩阵随旋转速度的改变展示谐振行为的结论。

In sagittal plane,the PPSI of each level moved from inferoposterior to superoanterior with an arc trajectory.The PPSI displacements and angular variation increased from L1 to L4,however,these two decreased in L5 simultaneously.The rotation radius had no relationship with lumbar segment.Flexion-extension ROM from L1/2 to L5/S1 increased gradually.

各腰椎屈伸运动时PPSI矢状位上呈由后下至前上的弧线轨迹，L1~L4其位移量和倾斜角度逐渐增大，L5两值同时减小；其旋转半径与腰椎序列无明确关系。L1/2至L5/S1屈伸活动度逐渐增加。

The invention relates to an electric machine (10) which can be operated as a motor or a generator. Said machine comprises a rotor (26a, 26b) rotatably mounted in a housing (12), a rotor shaft (24) which extends beyond the housing (12) and a plurality of electromagnet components (28) that are statically arranged in the housing at a distance from the axis of rotation of the rotor in evenly distributed angular distances. Said electromagnet components have each a wire-wound coil (30) consisting of a coil core (32) which carries one or more conductors.
