- Before that time, a haze of neutral hydrogen gas shrouded these first beacons in the infant cosmos. 再往前推进，则是一团团中性氢气所形成的薄雾，包裹著早期宇宙中第一批诞生的恒星。
- The bubbles will proliferate and merge, eventually clearing intergalactic space of neutral hydrogen [see box at right]. 气泡边界的清晰度，将能解答造成再游离的，究竟是大质量恒星还是黑洞。
- On otherwise, if neutral hydrogen content is very high, the refadiation from dust produces no effect on the 3K cosmic microwave background. 反之,如果中性氢的含量很高,则尘埃的再辐射将不可能使3K宇宙微波背景谱产生畸变。
- As the universe continued to expand, the temperature of the cosmic soup finally dropped below 2,967 Kelvin. Electrons began to combine with protons to form neutral hydrogen. 当宇宙不断膨胀,宇宙的温度亦随之下降,当温度低于2,967绝度温度时,电子和质子便会开始结合而成为中性的氢原子。
- As the first stars flickered on, their ultraviolet light excited neutral hydrogen atoms around them, causing the gas to emit a faint radio signal at 1,420 megahertz. 当第一批诞生的恒星开始闪烁，它们发出的紫外光会激发周围的中性氢原子，使这些气体发出频率为1420百万赫兹的微弱电波讯号。
- Using binary encounter approximation and Thomas Fermi approximation,charge stripping cross sections for hydrogen like ions Li 2+ and C 5+ by collision with neutral hydrogen and helium atoms are calculated. 使用双撞近似（BEA）和托马斯－费米近似（TFA）计算了类氢离子Li2＋和C5＋与中性原子H和He碰撞的电荷剥离截面。
- According to the prevailing view, once the IGM had cooled from its hot, ionized state to a colder mixture of neutral hydrogen and helium, it offered no effective resistance to gravity. 一般的观点认为：IGM一旦从它那炽热、游离的状态冷却成温度较低的中性氢和氦的混合物，它将无法有效对抗重力。
