本文利用星簇Cluste.的三颗卫星(C1,C3和C4)在2001年和2002年的数据,研究了快速对流事件(RCe.Rapid Conve.tion e.e.t)及其与亚暴的关系.结果显示单点卫星对RCe.观测,不能反映磁尾RCe.真实情况.在2002年7月25日发生的一次RCe.件,C1和C3观测到这次RCe.C4却没有观测到.在三颗卫星联合观测到的306次RCe.,C1观测到215次,C3观测到266次,C4观测到227次.统计研究表明,单点卫星观测到的RCe.平均时间也不能准确反映磁层内的RCe.由此推论在整个中心等离子体片内,快速对流事件所承担的能量和磁通量的输运量,可能远大于单点卫星观测给出的结果.用速度来定义的磁尾爆发性整体流(BBF,Bursty Bulk Flow)与亚暴的关系,比用磁通量定义的RCe.亚暴的关系要更加紧密.

On the.basis of the.plasma, e.e.tric and magne.ic fie.ds jointly obse.ve. by Cluste. and the.Double.Star TC-I space.raft in the.e.rth＇s magne.otail, we.have.inve.tigate. the.e.rthward flow bursts by introducing the.mome.tum e.uation in the.X-dire.tion in the.ide.l conditions of magne.o hydrodynamics （MHD）. One.e.rthward flow burst with a pe.k in e.ce.s of 500 km/s was se.e.te., whe. the.four space.raft of Cluste. we.e.locate. around -16 Re.and TC-1 was locate. around -10 Re.in the.X-dire.tion.

With the.me.sure. plasma and magne.ic parame.e.s from two space.raft at diffe.e.t positions in the.magne.otail, the.X compone.t of the.pre.sure.gradie.t was calculate.. Magne.ic te.sion was calculate. using the.mag- ne.ic fie.d me.sure. at four points, which could be.compare. with the.assume. constant in the.past re.e.rch with single.sate.- lite. Whe. the.pre.sure.gradie.t and the.magne.ic te.sion we.e.put into the.MHD mome.tum e.uation, some.sample. of the.e.rthward flow bursts we.e.acce.e.ate. and some.we.e.de.e.e.ate..

The.N-te.minal e.-hand calcium-binding prote.ns 1–3(Ne.AB1–3) constitute.a family of pre.ominantly ne.ronal prote.ns characte.ize. by the.pre.e.ce.of at le.st one.e.-hand calcium-binding domain and a functionally le.s we.l characte.ize.

This de.onstrate. the.capacity of the.family for inte.actions with various classe. of prote.ns. Ne.AB prote.ns e.hibit distinct subce.lular localizations: Ne.AB1 is found in the.nucle.s and cytosol, Ne.AB2 re.ide. in e.dosome. and the.plasma me.brane. and Ne.AB3 is pre.e.t in the.e.doplasmic re.iculum and Golgi apparatus. The.antibiotic biosynthe.is monooxyge.ase.domain, an e.olutionarily ancie.t compone.t, is akin to atypical he.e.oxyge.ase. in prokaryote. but is not we.lcharacte.ize. in ve.te.rate..
