Hardly had the elation in the wake of the 1,200 km-survival of quantum entanglement subsided before we again had news from Micius.On August 10,the joint team reported online in Nature the results from the other two major experiments aboard the satellite:Both the encrypted quantum key distribution(QKD)and quantum teleportation(QT)successfully passed through a distance of approximately 1,200 km,and did so less than
Hardly had the elation in the wake of the 1,200 km-survival of quantum entanglement subsided before we again had news from Micius. On August 10, the joint team reported online in Nature the results from the other major major aboard the satellite: Both the encrypted quantum key distribution (QKD) and quantum teleportation (QT) successfully passed through a distance of approximately 1,200 km, and did so so less than

太阳辐射作为地球上一切活动的主要能量来源,是地球气候形成过程最重要的因子,对地表辐射平衡、能量交换以及天气气候的形成都有着决定性的意义。太阳总辐射的准确获取不仅对气
红壤本身持水能力差,有效水库容量小,且经常发生季节性干旱,对作物的生长及水分关系产生严重的影响。土壤水分是作物生长过程中最重要的影响因子之一,而土壤保水能力的提高可以通过合理的施肥来实现。本文通过田间试验研究施肥制度对玉米生长及水分关系的影响,通过施肥改变土壤的物理化学性质,提升土壤的持水供水能力,从而影响作物的生长及水分关系,进而探讨施肥制度对“土壤-作物”水分关系的影响,为减缓作物受到季节性干
