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。

The signal-phase-matching principle of three and multi sensors are proposed in this dissertation. By using these principles, the formulae of estimated spatial signal are derived.

For the PUU/BO-g-VER (n-butanol graft VER network)hybrid film, the miscibility between the soft and hard segments in PUU phase was improved byadding the BO-g-VER network into PUU, resulting in remarkable reinforcement effect andgreat improvements of mechanical properties for the films. In the PUU/200-g-VER [Mn: 200,poly graft VER], the 200-g-VER network had considerable compatibility withboth hard segments and soft segments in PUU phase, then good reinforcement effect wasrealized, giving rise to higher tensile strength and elastic module, lower elongation at break ofthe hybrid films.

由于BO-g-VER与PUU硬段具有较好的相容性且促进了PUU软硬段间的微相混合，导致PUU／BO-g-VER hybrid膜的力学性能有较大程度的提高，体现了明显的增强效果。200-g-VER(分子量为200的单官能团聚醚接枝VER)与PUU软硬段均有很好的相容性，因此PUU／200-g-VER hybrid有较好的增强效果，使胶膜的拉伸强度和弹性模量提高，断裂伸长率下降。

结果表明：玛曲冰雹云中冰雹胚胎以霰胚为主；在地面降水中，固态降水占降水总量的46%，而霰占固态降水的65%，霰主要靠撞冻雨水和云水增长；雹云中存在较弱的过冷雨水累积带，累积带的维持时间也很短，累积带中的过冷雨水有利于雹块的增长，但不起主要作用；雹块的增长主要是通过雹撞冻云水，其次是撞冻雨水增长。
