Concretely speaking, using the irreducible tensor theory, we deuced the formulism for fine-structure energies of boron-like atoms in the ground and first excited states, which involves spin-orbit, spin-spin and spin-other-orbit interactions; completing all the angular integrations and spin summations needed, we make the final expression for fine-structure energies of boron-like atoms in the ground and first excited states in a combination of radial integrations. Afterwards, employing the wave functions we got in Chapter Three, we accomplished all the radial integrations and so obtained the fine-structure energies.

There are three reasons for people's extensive interest in spin squeezing. Firstly, the spin squeezing is an effective method to overcome the limit in precision improvement set by Heisenberg Uncertainty Principle. Secondly, because of the relationship between spin squeezing and entanglement, the research in spin squeezing is of importance for quantum information. Lastly but not the least, the entanglement is one of fundamental physics problems, so research in thespin squeezing has both practical and theoretical significance.

论文摘要：自旋压缩的研究受到广泛关注源于三方面的原因：海森堡不确定关系的普遍存在是量子测量器件精度提高的最根本障碍，如何抑制它对精度的影响有着巨大的应用前景；自旋压缩与量子纠缠的密切关系使得自旋压缩的研究对量子信息有着重要的意义；另外，量子纠缠是物理有待探索的基本问题之一，所以对自旋压缩的研究既有应用方面的意义，也有着基本理论方面的意义。
