1·Bathed in xenon spotlights, the white spaceship, attached to its twin solid rocket boosters and orange external fuel tank, crept 3.4 miles on the back of an enormous tractor called the Crawler.
沐浴着氙气聚光灯光，白色的飞船，带着一对固体火箭推进器和橙色外挂燃料箱，在称为“爬行者”的巨大拖拉机上缓慢行驶了3.4英里。
2·But that may not matter too much. Lasers are more efficient than xenon lamps, which waste a lot of energy as heat.
不过瑕不掩瑜，激光的效率比氙气灯高，因为后者的能量很多以热能的形式散失了。
3·On top of that, lasers last for a long time, whereas xenon lamps burn out and need to be replaced periodically.
除此之外，激光能够持续更长时间段，而氙气灯较快燃尽，需定期更换。
4·Lacking the halogen's delicate tungsten filament, which slowly evaporates with use until it finally “blows”, xenon discharge lamps are robust enough to last at least the lifetime of the car.
卤素灯的钨灯丝在使用过程中会慢慢的蒸发，直到最后断掉。由于没有卤素灯那样脆弱的钨灯丝，氙气气体放电灯十分耐用，其使用寿命至少不低于汽车的使用寿命。
5·Though costlier, xenon allows a discharge lamp to start far more quickly.
尽管成本高，氙气能够迅速启动发电灯管。
1·And down on this fission fragment it starts with xenon and ends with neodymium which is the last fission fragment.
最后到这个裂变碎片，它开始于，氙，结束于钕，那是最后的裂变碎片。
2·The krypton and xenon isotope ratios in the gas samples provided a surprising result: They did not match the ratios found in the primordial cloud that spawned the solar system.
气体采样中的氪和氙同位素比值产生了一个令人吃惊的结果：这些比值跟在形成太阳系的原始云团中所发现的比值不一致。
3·First, a range of less-dangerous gases are liberated, including tritium, krypton and xenon.
首先会释放一系列危险性较低的气体，如氚、氪和氙。
4·Accelerating 60 mile per hour consumes a mere 37 ounces of the xenon propellant on board, and that propellant has to last.
每小时60英里的加速只消耗船上氙推进剂37盎司，推进剂还得继续坚持。
5·On the basis of the first ionization potentials of the gases, Kossel noted that xenon was most likely to have the capability of forming fluorides and oxides.
在稀有气体一阶电离势的基础上，科塞尔注意到：氙最可能形成氟化物和氧化物。
