恒定场 meaning in Chinese

constant field
constant-field
permanent field
stationary field
stationaryfield

In pulsed field magnetization condition , we find some new phenomena characteristic , that is , the trapped fluxes of ybco bulk increase with increasing intensity of applied field up to about 1 . 9t , but decease beyond this value and the scanning distribution map of the trapped fluxes on the surface of the superconductor is not slick , which is different with the superconductors magnetized in constant magnetic field and the normal permanent magnets
超导体在脉冲场下具有特殊的励磁特性，当脉冲场在1 . 9t左右时，由于在脉冲场下超导体内的磁通线运动受到较大的粘滞力作用，超导体表面中心的俘获场分布扫描图将出现一些凹陷区域，这是跟超导体在恒定场下的励磁和一般永磁体所不同的。
