Expressions of electron young tables for their energy matrixes of the equivalence electron configuration(l_+~2l_-~1);

The relativistic effect is introduced,and it affects to the electron configuration and properties of the 6th periodic elements is discussed.

The standard Young tables corresponding to the space quantum state of the electron configuration ( l N 1 +l N 2 - ) are called the electron Young tables.

This paper studies the periodicity of atomic ground state which is determined by electronic configuration.

A simple and rapid method is suggested for deriving atomic spectral terms from equivalent electronic configuration.

The principal component analysis, one of pattern recognition methods, is applied to classification of electronic configuration of the odd parity spectrum of curium (CmⅡ) and some criteria for classification of configurations among 5f 87p、5f 76d7s、5f 76d 2 are obtained.

The result shows that the characteristic spectral lines from transitions between complex configurations of atoms and ions can be effectively excited by the impact of highly charged ions on a solid surface even though the ionic beam is very weak.

The effects of natural ecological factors on Taxus media is summarized,and the possible ways in which the ecological factors affect the physical activity of Taxus media are speculated in order to explore how the natural ecological factors affect the Taxol production.
