As a special social group, the ability environmental adaptation of the freshmen whose major is Physical Education, not only directly impact on their current physical and mental development, but also has the profound influence in the development of the University with far-reaching implications, meanwhile has the latent important value to their future development.

To better understand the basic metabolism and high capacity of environmental adaptation of this facultative intracellular bacterium from genomic perspective,we carry out the whole genome sequencing of P.

The environmental worthiness requirements with respect to weapon materials;

In order to improve appearance of rifles and solve the problems of color degradation of rifle receiver made from aluminum alloy,environmental tests of actual technics and improved technics of aluminum alloy anodic oxidation were conducted,and environmental worthiness of the anodic oxidation films was evaluated.

This paper discusses some basic concepts on environmental worthiness and environmental engineering, and the relations between environmental worthiness and reliability.
