以下为句子列表:
英文: Currently one of the major challenges associated with making MgB2 a useful superconducting material is to increase its critical current density at higher magnetic fields.

中文: 要将硼化镁制成有用的超导材料,目前最主要的挑战之一,就是如何在较高的磁场下增加临界电流密度。       更详细...
英文: For current densities above the critical current density, the vortices (the small nonsuperconducting regions of the sample) start to slip or move.

中文: 一旦这些区域开始移动,能量就会损耗,也就是说材料的电阻值不再为零。       更详细...
英文: On the other hand, in the four years since the discovery of superconductivity in this compound, the research community has made considerable improvements in critical current density, both in the low-field value and, perhaps more important, in the higher-f

中文: 另一方面,在发现这个化合物具有超导性的四年后,不论是在低磁场,或者是在更重要的较高磁场下,这个研究领域的专家已经将临界电流密度提高了许多。       更详细...
英文: The calculations axe based on the equation of current motion with temperature and field-dependent critical current density, and the heat dissipation produced by flux motion in the normal state region and the superconducting state region.

中文: 此计算基于电流运动方程,考虑到电流密度是温度和磁场的函数,考虑到在正常区和超导区由磁通运动产生的热耗散。       更详细...
英文: The critical current density of pure MgB2 is comparable to that of triniobium tin at low magnetic fields but falls off much more rapidly at higher fields.

中文: 在低磁场下,硼化镁的临界电流密度与三铌化锡相当,但是在较高的磁场下却下降得很快。       更详细...
