燃料球 meaning in Chinese

fuel sphere

This calls for the lasers to be very finely tuned and the fuel pellet to be perfectly smooth , so that the implosion is symmetrical and fusion occurs
这需要精确调节激光，燃料球必须光滑，这样内爆才会对称，聚变才会发生。
Fuel pellets can also be placed in the target site using conventional mechanical systems and these should easily be able to cope with the five mini - explosions a second needed to generate power
燃料球也可以利用常规机械系统放在目标地点，那些系统应付发电需要的每秒五次的小型反应轻而易举。
The fast - ignition technique is more like a petrol engine : first the fuel is compressed and only then is it ignited by a second laser pulse ? acting as a spark plug ? that is fired through a hole in the pellet
快速点燃法更象汽油发动机：首先压缩燃料，此后才通过燃料球上的一个小孔，用第二的激光脉冲发射器发射激光? ?起点火器的作用? ?将其点燃。
