针状物：太阳色球层边缘出现的明亮而细长的流焰·由许多细小的"火舌"组成，宛如簇簇燃烧着的草丛。针状物的长短、宽窄很不一致，高度约有几千千米，宽约1000多千米，它们在色球中不断产生，又不断消失，存在时间一般为10分钟。
通过在针状物上施加电压，一个从液体提取离子并加速他们到一个非常高的速度然后强迫它们飞离的电场就被创造出来。
By applying voltage to the needles, an electric field is created that extracts the ions from the liquid, accelerates them at very high speeds and forces them to fly away.
这个薄薄的面板由1000个多孔的聚在一起的类似针状物的金属结构制成，并且在每个针状物上面都有数克的液体离子。
This thin panel is made of about 1, 000 porous metal structures that resemble needles and have several grams of the ionic liquid on them.
