,higher σ b and lower HB,or lower σ b and higher HB,using the method of heat analyzing and polyparameters analytic figures,the synthetic rules of carbon saturation degree,inoculation degree and mechanical properties can be exposed.

Based on the annotation of coupling between urbanization and eco-environment,the rule curve has been deduced by combining "S" curve of urbanization growth and inverse "U" curve of eco-environment changing,and the coupling rules of China been tested and the causes been explained.

According to the basic coupling characteristics and temporal rule between regional urbanization and eco-environment,the coupling rules between urbanization level and "three waste discharges" in Jiangsu have empirically been tested and the mechanisms have theoretically been explained.

In order to keep away from the deficiency of ESD theory and the unfit test tools for ESD radio field,a homemade PCB with certain function is used as the electronic system under test in this paper,and try to research the energy coupling rules between the system and ESD through the electrical parameter of the system under test and electrostatic discharge voltage.

The investigation includes microelement background value and combination law of road dusts in element character of geochemistry.
