For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.

中文摘要：我们首次研究了非最小耦合标量场作为宇宙暗能量－Quintessence、Phantom的可能性；构造了一个实标量场驱动的加速－减速无限循环，永恒膨胀的宇宙模型；详尽讨论了具有Tachyon场的经典和量子虫洞；研究了一般球对称黑洞缘于任意自旋量子场的熵，给出了熵与量子场简并度之间的正比关系；首次研究了deSitter背景时空下具有中微子场的稳态黑洞的似正规模与具有任意自旋场的Schwarzschild黑洞的似正规模问题；首次研究了弯曲时空背景下的量子通讯问题。

In this thesis, the normal form of open-phase operation in large powerunit is analyzed in theory with the method of sym-metry-ponderance. The normal formof open-phase operation in large power unit is studied respectively by MATLABsimulation.

本文针对几种常见的发电机组非全相运行，采用对称分量法得出了各相电流、各序电流及相序电流间的关系；并用MATLAB软件进行了仿真，验证了理论分析的结果。

The research on the credit of tax of tax law is made because: First, at the macro level, the rights and obligations between taxpayers and tax payees are very asymmetric.

对税法的税收信用进行研究主要基于：一是从宏观层面讲，纳税人与征税人之间权利和义务关系极不对称，纳税人享有权利过少，总是处于服从和不被尊重的地位；二是从权力层面讲，征税人自由裁量权力过大，纳税人对征税人的信任度降低，导致双方税收信用下降；三是从利益角度过分强调国家对纳税人部分权益的无偿强制占有，致使纳税人为追求利益最大化而采取法律禁止的偷、逃、骗、抗税，带来纳税人的反感和反叛，无税收信用而言。

From the angle of asymmetric information, this paper has analyzed the principal-agent relationship between the property management company and owner.
