impactor信息详情
n.撞击器；悬浮微粒的取样器
fritted impactor───烧结冲击器
In such collisions, the impactor is completely destroyed and its material is incorporated into the larger body.───在这种碰撞中，撞击者被完全摧毁，其物质被并入较大的天体中。
In a titanic collision model, the bulk of the Moon would have formed from a combination of material from the impactor and Earth's mantle.───在泰坦尼克碰撞模型中，月球的大部分是由来自撞击者和地幔的物质结合形成的。
Such a titanic collision between Earth and a Mars-size impactor may have given rise to Earth's Moon.───地球和火星大小的撞击物发生如此巨大的碰撞，可能导致了月球的形成。
The space craft will not land on the moon, though it will send a small "impactor" probe to the surface.───飞船将向月表发射一枚“撞击”探测器，但是不会在月球着陆。
"In a way you do make a crater, but you fill it all in with the impactor material, " says Asphaug.───“从某种意思上说，碰撞过程中产生过环形山，但是参与碰撞的物质又把它填满了。”Asphaug说到。
The impactor: A large spacecraft slams into the asteroid hard enough to jolt it off its Earth-bound track.───冲撞器：一架巨型太空飞行器猛力撞上小行星以让它偏离直冲地球的轨道。
The test variables include the effects of changing the size of impactor and distance between impactor and receiver.───实验变数包括改变敲击元尺寸及接收器距离对检测的影响。
The presence of hydrocarbons, and the absence of carbon monoxide, provide strong evidence for a water-depleted impactor in 2009.───出现了碳氢化合物，没有出现一氧化碳，强烈显示2009年的撞击物是缺水的。
Deep Impact first visited Comet Tempel 1 in 2005, crashing an impactor into the comet to help scan its composition from afar.───“深度冲撞”号于2005年第一次造访了彗星Tempel1，为了分析该彗星的构成，它抛出了一个冲撞器。
These of course raise little or no dust unless the impactor reaches the ocean floor before detonating.
Loss of atmospheric gases and impactor materials to space becomes even more important for larger explosions.
Much depends on the exact size, energy, and location of the impactor.
The percussion and rotary drilling of hydraulic impactor may heighten drilling velocity several times, when it is been applying in drilling geothermic well.
The impactor slammed into the mostly molten proto-Earth, splashing a goodly glop of magma into space where it first became a Saturn-like ring before coalescing into the moon.
Geologists agree that the Sudbury impactor was at least eight kilometers ( about five miles ) across.
The most economical mechanism for tight shutoff is the impactor handwheel.
By mending parameter definition of the new impactor using simulation experiments, assessment performance of the impactor was improved.
Impact explosions begin with the nearly instantaneous conversion of the kinetic energy of motion of the impactor into heat.
