Flora transitiona and its biogeographical significance

We examined spatial patterns of floristic transition in north-south range-gorge region in Western Yunnan and the biogeographical significance.

A new species of Ypsilandra (Liliaceae) is firstly described and illustrated, and its biogeographic implication is discussed.

Wavelet multiscale analysis and geophysical significance of the spontaneous potential of oil and gas reservoir;

Advances in the research of physiological significances and genetic regulation of lignin metabolism;

The paper stated the physiological significance of ACE in blood regulating, the kickback of ACEI, the different ACEIPs from food protein and their characters, and the apply prospect of ACEIP in functional food against hypertension.

This text passes to introduce the "entropy" of physics meaning,and the relation of the entropy and environmental protection,in order to build up people proceeding environmental protection with air of tension,enhancing people's concept of taking good care of with environmental protection,along continuable development roadway.

Then the physics meanings of obvious and concealed circles of gravity center of human body are probed, and the principle mentioned above is extended.

It is generally believed that only circuit value of electro-magnet vec tor-potential A has physics meaning while value A on each point does not.
