The paper reports the insufficiency and flaw of traditional experimental methods of Zeeman effects and has improved the methods from three aspects:the instrumentation equipment,the picture observation and the data processing.

The theoretical interpretations to the normal zeeman effect phenomenon;

An Analyses of Zeeman Effect in different magnetic fields;

Probing into Several Key Problems in Zeeman Effect Experiment;

A Comparison between the Raman Effect and the Fluorescence Process;

Using method of conservation for moment and energy,The influence of Raman effect on band-limited amplified soliton transmission system are studied.

The Study of Raman Effect in the Liquid-core Optical Fiber of CCl_4 by Group Theory;

Then we present the nonlinear processes in silicon waveguides such as Raman effect、 four-wave mixing and wavelength conversion efficiency,as well as progresses in optical devices and technology due to these nonlinear effects.
