Therefore, it is necessary to explore new materials that can protect and prevent these electromagnetic waves [2, 3].
In general, materials that can be used as absorbers of electromagnetic waves need to have electrical and magnetic losses [4].

These punches were then tested on various materials on an industrial high-speed stamping press.
Introduction As part of the global trend towards energy and resource efficiency, high-strength steel materials, aluminum-magnesium alloys and stainless steels are increasingly being processed [1, 2].
The use of these materials allows structural components to be made significantly lighter, thus reducing emissions, and making more efficient use of the energy available for combustion driven and electric vehicles [3].
The use of higher-strength materials also increases the load on the tools, which leads to accelerated wear and reduced service life [4].

One of feasible ways of handling dredged soil is to add some curing materials to the soil and make them convert into artificial modified soil with better engineering characteristics, which can be used in dike reinforcement and filling engineering.
There has been fairly many achievements about modified solidified soil, from common cement as curing agent to new improved curing materials [3-7], with different research objects and methods.

Discussion on Structure Design of Shaft Lining Built in Porous Rocky Aquifer with High Water Pressure Xiao-min Zhou1,a,Bing Deng1,b, Cheng-xuan Ma1,c 1.Civil and Environment School, University of Science and Technology Beijing, Beijing 100083,China agroundfreezing@gmail.com, bdengbin198871@163.com>, cmcxxy@126.com Keywords:shaft, shaft lining structure, shaft lining thickness design, porous rock aquifer, water tight concrete, water pressure.
Thirdly, the principals of interaction among high pressure water, lining and surrounding rock are revealed by figure and discuss on inequality inequation; With a newly application example, the practical usage are introduced and newly viewpoints are opened to designers with material promotion, arrangement of re-bar or bolt, structure optimumetc.
It fit to decrease the thickness of the shaft lining if the shear modulus of lining is close to the enclosure rock. 5) Optimumdesign of the shaft lining The load of the exterior margin in “Baoshen” is much different from Lame’s in substance, in former contain more factors, not only relate to the water pressure and seepage field, but also to the dimension of the lining, the matching properties between lining and the surrounding rock’s material.
After Formula (5) reveals the principle intuitively. 4) From the formula (5), to reduce the thickness of shaft, the high grade concrete is not the only way else to solve this kind problem, it may improve the shear modulus of concrete, develop new material to close the shear modulus of enclosure rocks, or to use the high performance concrete.
