Through the investigation on the readers violation phenomenon in university library,this paper analyzes on the causes of the generation of the violation phenomenon,and puts forward some methods for solving this phenomenon.

This paler bricfly passes on the development statusr of electrokinetic phenomena of interface and the model for the double electrical layer.

The electromechanical behaviour of bone concerns two mechanisms:the piezoelectricity and the electrokinetic phenomena,This paper reviews the studies on them,including the origins,experimental techniques and some obtained results.

Based on the past research outcomes,according to completely stress-strain curves and softening property of coal-rock mass,this paper explored the mechanism of the genesis of mine dynamic phenomena and put forward a mew method which might make a breakthrough to predict this mechanism.

It is a source of dynamic phenomena in Beipiao mine are.

The depth of coal mining in Yanshitai mine is over 600 m,dynamics phenomena have been occurred of ter during mining ahd excavating.

To find out original rock stress direction and quantity degree can help to assure that mine design,construction and production are economical, safe and highly efficiency, it can also help to determine the layout of roadway and face, support type, and to predict mine dynamics phenomena.
