为了避免过热，因为在任何液体燃料火箭进程的混合物故意不理想。
To avoid overheating, the mixture in that process in any liquid-fuel rocket is deliberately not optimal.
液化推进火箭通过燃烧产生喷气的材料是液体；这种液体有点像汽油、煤油或酒精一类燃料。
The material which the liquid-propellant rockets burn to make the jet gases is liquid. This is something like gasoline, or kerosene, or alcohol that can brun.
