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.

首先采用不同的方法分别建立了大跨桥梁索塔的精细有限元模型和简化模型，运用环境振动实测结果对简化有限元模型进行了修正，并和精细模型计算结果相比较；研究结果表明：严格按照设计图纸建立的精细有限元模型计算得到的动力特性与索塔现场环境振动实测值之间的误差较小，而未经修正的简化模型误差较大，由此说明：大跨桥梁在有限元建模时应尽可能详细地反映结构的几何与材料特性，在此前提下，对于设计资料全面的桥梁结构，建立有限元模型时就只需要修正那些无法用数学和物理方法模拟的不确定因素。
