The theory and new methods of identifying messenger traits in selection criteria were introduced in this paper to propose the practical formulae of calculating trait information contents.

An Investigation on Junior High School Students Collecting and Processing Ability of Physics Information;

By using dissipation structure theory as a guide in physics teaching,physics information should be collected from outside human brain,which is not isolated from outside world,and physics information should be exchanged with information form outside human brain,which is not balanced itself.

The theory and new methods of identifying messenger traits in selection criteria were introduced in this paper to propose the practical formulae of calculating trait information contents.

In this paper,we highlight some relevant key issues,including network-based synchronization,traffic dynamics on networks,structure and evolution of information networks in the next generation,evolutionary cooperating game,complexity of biological networks,human dynamics and infophysics.

Relationship between nicotine content and physical property in flue-cured tobacco leaves;

122 samples of cutters in flue-cured tobacco leaves from south tobacco-growing areas of China were used as materials to analyze the relationship between potassium content,chlorine content,ratio of potassium to chlorine and physical property.
