But in that case , too , a catalyst would be needed to boost reaction rates enough to account for the dearth of acetylene .
但在那种情况下，也需要催化剂去加快足够的反应速度，以解释乙炔的缺失。
In may 2010 , two teams of scientists announced that nasa 's cassini orbiter showed titan is harboring an unusual chemical dance party with hydrogen and acetylene .
This would result in a lack of acetylene on titan and a depletion of hydrogen close to the moon 's surface , where the microbes would live , they said .
他们说：这可能造成“提坦”卫星上乙炔的缺失和靠近卫星表面氢的耗尽，那里是微生物生活之处。
Infrared spectra of titan 's surface taken with the visual and infrared mapping spectrometer ( vims ) showed no sign of acetylene , even though ultraviolet sunlight should constantly trigger its production in the moon 's thick atmosphere .
