The students can't catch on the essence of the relationship between the atomic structure and the element properties, and they often mistake the element's properties for the atomic's.

对"原子结构与元素性质的关系"存在着各种糊涂的认识，往往将单质的性质误认为是元素的性质。

With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples. The direct determination of extremely low concentration of trace element with modern atomic spectroscopic method, such as atomic absorption spectrometry is so difficult. On one hand, the limitations are associated not only with the insufficient sensitivity of these techniques but also with matrix interference.

随着科学技术技术的发展，在进行地质、环境、生物等样品中痕量金属元素的测定时，常常要求达到ppb级的水平，虽然火焰原子吸收分光光度法具有很高的灵敏度，但是要直接测定这些样品中的痕量组分却很难，这是因为，一方面，样品本身的物理化学状态有的不适合直接测定，或组分的含量低于分析方法的灵敏度；另一方面是存在基体干扰。

In addition, the smaller granule is obtained by selecting those objects of the larger granule that satisfy the atomic formula.

在一个粒度层次中，每个结点都是数据对象的子集，连接大粒度到小粒度的弧用一个原子公式定义。

The NT algorithm takes advantage of a novel formula for calculating atomic interactions that greatly reduces the computational load.

NT(中立域neutral territory)运算法则利用新颖的公式计算原子间相互作用，大大减轻了计算机加载的工作量。

In this paper, after taking over coupling effect between electronic spin and orbital angular momentum, to revise the formula of electronic angular momentum in Bohr's theory, and electronic speed formula is obtained in a single-electron system, and to correct the energy level formula of atomic orbit in Schr? dinger's method by relativistic effect, the theoretical improving formula is built for spectrum fine splitting calculation, the calculated values are in good agreement with experimental ones, and reflect changing law of spectrum fine splitting values.

本文在考虑了电子的自旋角动量与轨道角动量的耦合作用后，通过对Bohr理论中的电子运动角动量的修改，推导出单电子体系的电子速度公式，结合对Schrdinger的原子轨道能级表达式相对论效应修正，从而得出本文的氢及类氢离子光谱精细结构值的理论计算公式，应用此改进公式，所得的计算值与实验观测值符合得很好，计算结果也反映了氢及类氢离子光谱精细结构数据变化的规律性。

The atomic formula is called atom for short in predicate calculus.
