在这些“睡眠”时期中，新视野号仅仅靠一台放射性同位素热电发生器驱动，而它的耗能还不及一制10 0瓦的家用电灯泡。
During these periods of "sleep," New Horizons is powered by a single radioisotope thermoelectric generator and USES less power than a pair of 100-watt household light bulbs.
同时它应该具备可靠、稳定的能源供应，最好能够使用放射性同位素热电发生器(RTG)。
There wouldalso be the requirement of a reliable, steady supply of energy, so theuse of radioisotope thermoelectric generators (RTGs) would be preferred.
