宇宙高手-
More and more researches have shown that most of the intense geomagnetic storms are caused by fast coronal mass ejections in interplanetary space ( icmes ). though the ace satellite can provide solar wind data in almost real time for prediction of geomagnetic storms, the time interval is too short ( shorter than 30 - min ) for effective predictions of major geomagnetic storms
位於拉格朗日點的ace衛星可以提供近實時的太陽風數據,但依據ace衛星太陽風數據進行地磁暴預報,時間的提前量非常有限,對于大地磁暴,這個時間提前量往往不超過30分鐘,這樣的時間提前量對于實際應用來說,是不能令人滿意的。 -
Abstract : with adopting of a frame of the principal fibre bundle. the article constructs a unified model of gravity and electromagnetic with torsion both in internal sp ace and in four - demensional space - time. the curvature on the bunde is calcula ted using connection theory in the principle fibre bundle. the action is construc tod with the curvature. the field equations are achieved. finally a discussion is made
文摘:應用纖維叢理論,在內部空間和四維時空引入撓率,建立了引力與電磁場的統一模型.利用纖維叢聯絡論求出主叢的標曲率,由它構造作用量,求得場方程,最後作一些討論
