While for the multiple particles system, this is also called normal mode splitting.

The results show that(1) the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-direction(up or down)of the electrons transferred is in accordance with the symmetric characteristics.

The dynamic compressive modulus and the split resilient modulus of fiber reinforced asphalt concrete are obtained,dynamic mechanism of asphalt concrete with different fiber contents is analyzed,relations between dynamic compressi.

Based on the characteristics in the strength of coal seam under the action of the ground pressure, the impact coal cutting is achieved in the coal winning technique by using the impact cutting tool to impact, split and cut the coal on the coal wall.

To the cracks on the bottom of the slabs,the effect of water is just like the uniform forces assigned on the crack face which lead to the cracks to split.

Plain high strength concr ete and plain normal strength concrete,fiber high strength concrete and fiber no rmal strength concrete were tested respectively with split test and their capaci ty to resist propagation of.

Several suggestionsto improve the method of testing cleavage strength were presented.

Based on stress analysis of soil mass in the course of cleavage grouting,the cleavage type of different kinds of soil mass is discussed in this paper.
