The Influence of Rotating Magnetic Field on DCEN MAG Industry Welding based on Properties of Welding Materials Xuming Wang 1, a, Wei Liang 1,b and Suhong Sun 2,c 1 North China Institute of Science and Technology, 065201,China 2 Beijing Institute of Business and Technology, 065202,China awangxuming@ncist.edu.cn, bliangwei@ncist.edu.cn, cfengling123@sina.com Keywords: Rotating magnetic field, DCEN MAG industry welding, Excitation current and frequency, welding spatter.
And its mechanism is researched carefully using high velocity camera.When fixing excitation frequency or excitation current, arc motion behavior, droplet transfer, wire melting coefficient and properties of welding materials are researched.
Nevertheless, wire is cold cathode materials, and cathode drop is much higher than anode.
The properties in welded seam were approach to original materials.

Therefore, relative to the traditional Wushu sports equipment made of wood, steel and ordinary cotton materials, fiber reinforced composite materials have obvious advantages.
Thus, the modern advanced materials into Wushu equipment has a lot of space.
Plastics and composite materials are the preferred sports protective materials to protect athletes body from harm.
Conclusion The rapid development of modern materials science, especially the appearance of fiber-reinforced composite material, can promote the reform or improvement of protective gear, the target, performance equipment and fitness equipment in Wushu activities.

The biomass of each specie was calculated according to the materials of tally, such as height, diameter and so on in the forest inventory data.
Materials and methods Summary of the study area.
First, the main tree specie’s biomass model in the study area was collected and established, and all tree species’ biomass per area was calculated based on the tally materials of the forest resource inventory; then subcompartment biomass was calculated based on the tree specie composition and the subcompartment area of the subcompartment investigation materials.
