Electromagnetic properties of Carbon fiber and Glass beads will be enhanced after metals such as Ni, Fe, Co and Ag are electroless plated on their surfaces so that they can be utilized as electromagnetic shielding materials and stealth materials.
Carbon fiber and Glass beads are non-metal materials, which need be coupled and activated before electroless plating.
(4) The mixed dusty material( Ni-P-CFs/GBs) is good electromagnetic shielding material, which has important reference value for thin-coat, lightweight, powerful-absorption, and wide-frequency stealth materials.

Introduction Zinc-manganese battery is one of the largest amounts of batteries, which has many unique advantages [1], such as the cheap and abundant raw materials, a simple production process, a relatively large battery capacity, conveniently portable, etc.
Zinc is not only used as an anode active material, but also as the battery case.
Plastic seals and anode cap were as seal materials.

Introduction Biodegradable macromolecule materials[1-3], due to having fine mechanical properties, processed properties and biodegradation, such as poly(lactic acid), poly (butylene succinate), poly (caprolactone),were expected as the environmental macromolecule materials which can be the most hopeful substitute of common plastic ,such as polyethylene and polypropylene[4-5][7].
In order to produce the degradation materials which can be fit to different area environment, we should carry out researches which can control degradation speed of the materials structure composition.

Materials and Method The three types of TWB that were analysed are presented synthetically in fig.1., that presents a circular blank realised through the welding of a disk-shaped part and a ring-shaped part, each made of steel with another thickness.
In the flange area, there is a thickening of the material, with a maximal value of 14%.
In particular, there need to be studied problems related to material failure criteria, design of the technological process and its control, as well as other details related to the deep-drawing of welded parts made of the same material but of different thicknesses but also of sheets made of different materials in order to achieve, on certain part areas, for example a higher wear resistance.
