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.

具体地说，利用不可约张量理论导出了类硼离子基态以及第一激发态的精细结构的表达式，给出了自旋-轨道、自旋-自旋、自旋-其它轨道相互作用等所涉及的所有角向积分和自旋求和的解析计算方法，完成了角向积分、自旋求和的计算，使类硼离子基态以及第一激发态精细结构能级最终可以表示为径向积分之和；在此基础上利用以前所得到的非相对论性波函数，进一步完成了所有径向积分的计算，从而得到了对应能级的精细结构的理论计算值。

In [28], the author has proved the feasibility in mathematics. In this paper, we propose a direct sum decomposition algorithm of AFS structure based on the research in [28], which decomposes a complex AFS structure into several independent sub-AFS structures, thus the elements in the same sub-AFS structure are dependent on each other, the elements in the different sub-AFS structures are independent.

本文在文献[28]理论研究的基础上，具体提出了AFS结构直和分解算法，实现了把一个复杂的AFS结构划分为若干个相互独立的子AFS结构，使得同一个子AFS结构中的元素是相互关联的，而不同子AFS结构中的元素是相互独立的，即每个子AFS结构均是一个连通系统，从而有效地降低了分析AFS结构的难度。

PDC bit crown profile, consisting of single circular arc parabola profile or dual cone profile with deeper inner taper is introduced. Cutter arrangement for various bits is determined. The bit is improved by the application of hybrid cutting structure and detailed analysis of hydraulic structure. Simultaneously, bit stability is enhanced using multiple bit stable structure design techniques such as deep inner taper, force balance and hybrid cutter arrangement etc.
