With the development of high temperature superconducting materials production technology, critical current density of high temperature superconducting Bi-2223/Ag tapes has been greatly improved[2], the high temperature superconducting coil has been closed to the actual application level.
Superconducting magnet as electromagnetic energy storage element, the flow capacity rated to the endurance of magnetic field, when design the magnet, the first consideration is that superconducting materials must meet the requirement of magnetic field, including the distribution of magnetic field in space and variation with time.

The materials of the seat.
The materials are abundant, mainly has wood, stone, concrete, imitate stone, metals, ceramics, plastics, and so on, in which wood is the best option because it is warm and comfortable.
Selection should be based on its function and the space environment to match the materials and processes.
The cleaning ground should apply impervious material paying attention to drainage and garbage disposal work.

In order to remove the magnetic interference, non-magnetic material is used for the outside of the piston.
It is noted that the material for the inner and outer piston is mild steel featuring a strong magnetic property, while the material for the piston rod and cylinder is aluminum featuring relatively low permeability.

(1) where P , rolling force(kN); B , strip width(mm); cl , contact segment of work roll and workpiece length of horizontal projection (mm); pQ , external friction stress state coefficient; mK , metal deformation resistance determined by chemical composition of metal materials and physical conditions such as deformation temperature, strain rate and deformation degree, taking a plane stress state when the vertical rolling mK σ= (MPa); σ, deformation resistance (MPa).
There are a lot formulas about the plastic deformation resistance of metal but also have to consider the material chemical composition and physical conditions of deformation (deformation temperature, deformation speed and deformation) and other factors[7].
Finite Element Model of Vertical Rolling Process Rigid-plastic finite element method was used with rigid material model for workpiece[8-9].

The welded will show up lighter, and the darker material next to it is the rearranged grain structure, due to the heating and cooling cycle.
First the material is cleaned, polished, etched and dried.
The weld will show up lighter, and the darker material next to it is the rearranged grain structure.
