Dem l71 presents a textbook example of the double - shock structure expected to develop when a star explodes and ejects matter at high speeds into the surrounding interstellar gas Dem l71是双激波结构的标准范例，人们认为其产生于恒星爆发并以高速向周围星际气体抛射物质的时候。
The seismic wave madding by the detonating seismic hammer have higher frequency and remedy the disadvantage of the lower energy utilization of the concentrating energy source 爆炸地震锤由爆炸射流抛射锤头撞击地层，激发地震波具有较高的频率，同时弥补了聚能震源弹能量利用率不高的缺点。
Other eyewitnesses depose that they - observed an incandescent object of enormous proportions hurtling through the atmosphere at a terrifying velocity in a trajectory directed south west by west 其他目击者还作证说，他们瞥见一颗发白热光的庞然大物，以骇人的速度沿着抛射体的轨道朝西南偏西方向腾空而去。
Our earth is constantly bombarded by high - speed high energy particles 400 km sec and radiation from the sun . we are shielded from these hazards by earth s atmosphere and magnetic field 地球其实不断受到太阳向外抛射的高速高能粒子每秒400公里和辐射的袭击，可幸我们受到地球大气和磁场的保护才幸免于难。
Solar activity , especially , coronal mass ejection ( cme ) during a large solar activity affected the space environment of human being and could be one of main reasons of the space disaster 太阳活动密切地影响着日地空间环境和地球高空大气结构，太阳耀斑爆发产生的日冕物质抛射( cme )是空间灾害的主要原因之一。
Since sunspot number is closely related to solar activities like flares and coronal mass ejection , the sun might have entered a low - activity state for a rather long period of time during these minimums 由于太阳黑子数目与如耀斑和日冕抛射等太阳活动关系密切，在上述太阳黑子极小期内，太阳的活动可能沉寂了一段长时间。

Sunspots are islands of intense magnetic bundles punching through the solar surface . the magnetic bundles constantly interact with each other and sometimes create unstable configurations that then lead to eruptions in the form of flares and plasma ejection 其实黑子是磁缆贯穿太阳表面的地方，这些磁缆会互相影响，有时会出现不稳定的排列，引发耀斑和等离子体抛射等表面爆发。
Solar wind flows out from the corona the sun s outer atmosphere into interplanetary space at speed of between 300 and 900 km per second . it causes fluctuation to the earth s magnetic field , which we call magnetic storm . such event will cause deflection of compass needles 而太阳风则以每秒300至900千米的速度由日冕太阳外大气层向外抛射，进入行星际空间，对地球磁场造成扰动而产生磁暴，导致指南针指针偏移，严重的话更会导致电力受阻和电话线路中断。
Haunting her enemies with relentless fervor , she is able to throw a dagger - like projectile that allows her to chase her prey beyond physical boundaries , and the fear and the desolation struck in the hearts of those who have the misfortune of encountering her alone is a pain impossible to withstand 她永不懈的缠著她的敌人，藉由掷出匕首般的抛射将允许她突破物质的界限来逐杀她的猎物，那些单独碰上她的?伙将体会到直达内心深处的恐惧以及孤寂并且毫无反抗之力。
