第一遍盲听，第二遍看原文

if we had zero resistance conductors , we could have trains ,that could  be levitated and transit people  from one corner  of the country to the other with almost no power . It’s was completely change the way electric car’s work .magnetic resonance imaging is quite expensive ,that would tremendously change also .even fusion could potentially be  dramatically  changed our quest for fusion , we  sort of imagine  this could be a real  revolution in technology 

The new discovery is first time we (demonstrating a material that ) superconducts at room temperature and near-ambient .

Before the pressure was 270 gigapascal  ,the new discovery ,now we are at one gigapascal
