脉冲场梯度凝胶电泳 pulsed field gradient gel electrophoresis
双重脉冲场凝胶电泳系统 secondary pulsed field gel electrophoresis
脉冲 impulse; pulse; impulsion; out-burst; pip (荧光屏上的) 一个光脉冲 a pulse of light; 一个声脉冲 a pulse of sound; 一个压力脉冲 a pulse of pressure; 在低频率(譬如每秒十次)时, 所感觉到的是脉冲而非振动。 at low frequencies, such as 10 per sec., pulsation is sensed rather than vibration

At first , the interactions of hts permanent magnet and applied field are studied , that is the levitation force of ybco bulks over the ndfeb guideway and the influences of the applied field to the hts permanent magnet . secondly , the pulsed field magnetization properties of ybco bulks are studied . at last , the influence of the sample ' s thickness , shape as well as the density to the levitation force over the ndfeb guideway and the trapped flux of ybco bulk are studied 文中主要研究了高温超导永磁体在外场下的受力状况以及外场对其内部磁通量的影响、高温超导ybco块材在不同脉冲场下的俘获磁通特性以及超导体块材自身的厚度、形状、密度等参数对其在外场下受到的悬浮力和俘获磁通的影响。
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。
