讨论了激光聚变反应堆腔室中残余气体在球团注入时的影响，包括低温靶的寿命、阻力引起的失速、侧风引起的偏差和球团自旋引起的升力。假定每次都以指定的速度和方向准确地注入颗粒。初步结果表明，为了将燃料颗粒输送到射击位置，膛内蒸汽压应小于0.1 Torr，弹间风速变化应小于1 m/s，精度为100 μ m。
Influence of residual gas in a laser fusion reactor chamber at the time of pellet injection is discussed, including the lifetime of a cryogenic target, the stall by drag force, the deviation by a crosswind and the lift by spin of the pellet. The pellet is assumed to be injected accurately with designated speed and direction every time. Preliminary results indicate that the vapor pressure in the chamber should be less than 0.1 Torr and the shot-to-shot variation in the wind speed must be less than 1 m/s to deliver the fuel pellet at the firing position with an accuracy of 100 mu m.
