Another sign of ice is the presence of parallel lines and pitted material on the crater floor.
另外一个有冰存在的迹象就是陨石坑底部的并行线和无核物质。
Solar halos are also caused by small, flat, six-sided, ice crystals that float down parallel to the ground.
太阳光环也是由微小、扁平、六面形的冰晶在同地面平行地飘落所引起的。
Parallel linear cracks are also observed along the crater wall over the gullies, which could be due to thermal contraction of ice-rich material.
在陨石坑口壁上也发现了并行线一样的裂缝，这可能是由于含冰物质热收缩现象造成的。
There is a power coupling and separating process between ICE and motor in the parallel-type hybrid vehicle, and the energy management strategy is comparatively complex.
并联混合动力汽车中内燃机和电机之间存在动力的耦合和分离过程，能量管理策略比较复杂。
