According to environmental conditions of loess plateau in Luliang of Shanxi Province,the paper proposed some suggestions about plant protection and vegetation restoration for expressway slope,also discussed the basic principle of plant protection,methods for planting and water and soil conservation as well as plant cultivation.

Based on the principle of the slope plant protection and reaction way,with the help of the hydraulics and sediment corrosion theory and formula,calculation ways for the function effect of the slope plant protection are obtained,the canonical calculation way for the ability of the slope plant protection is inexistent.

Novel radiation coefficient tester for protective fabrics;

This paper briefly describes some kinds of electromagnetic shielding fabric, and introduces some new products and developing trends of the electromagnetic shielding fabrics at home and broad.

Objective To investigate the effect of electromagnetic pulse(EMP) with different field intensities on learning ability of rats and to explore the role of physical protection in the effects.

The anticorrosive technology of buried pipeline is introduced, discussion is also carried out from physical protection, electrochemical protection, coating and other aspects.
