摘要
无磁杜瓦在超导技术应用中是一个不可或缺的工具,尽管它不是超导技术的主流研究课题,但在许多应用领域中由于它的缺陷却是妨碍推广应用的主要矛盾,频带窄就是一个阻碍成功应用的问题所在。本文作者通过研究采取切断无磁杜瓦中敷金属薄膜产生渦流的通路,使无磁杜瓦带宽变宽,研制出一种频带能满足地球物理勘查要求的新无磁杜瓦。
Non-magnetic dawer is a useful tool in superconductor application. But its narrow frequency band hinders the widely application of superconductive technology. Cutting the passage of vortex flow that is producted by metallized film of dawer to make the frequncy band widen, a new non-magnetic dawer fitting geophysical exploration is developed.
