但不能因为“申请—审核”制中存在个别问题,就否定这一制度,重新实行“考博制”。我国之所以取消“考博制”,而试行“申请—审核”制,就是因为“考博制”,强调用考试成绩录取学生,这不但影响导师的招生自主权,而且也存在考博应试化的问题,很多被录取的博士生,只会考试,而没有学术研究能力。“申请—审核”制,就如当前硕士研究生招生的推免制度,而“考博制”就是统一考研。虽然也有人质疑“推免”加剧保研内卷,对普通院校学生不公平,但是我国硕士研究生招生改革的方向,是扩大推免,减少统一考研,而非减少推免。

Mostly. This is because, theoretically, we could still save the ISS and move it into higher orbit. NASA has calculated that propelling the station more than 640 kilometers above Earth would keep it alive for 100 years—and also require at least 18.9 metric tons of propellant. That’s roughly 2,000 airline carry-ons. A thousand years would require at least 36 metric tons. If that doesn’t seem like very much, consider the fact that, right now, no vehicle can transport that amount of gas to the station. The still-in-development SpaceX megarocket Starship might be able to haul a significant percentage, but it would struggle to dock with the station, according to the space agency’s estimations.
