他还说到，底线是“我们意识到的能够引起这么多同位素离散的过程是，月球上的氢含量比地球少10000到100000倍。”
The bottom line, he says, is that "the only process we are aware of that could cause such large isotope scatter is if the hydrogen content of the moon is 10,000 to 100,000 times less than [on] Earth.
一段时间后，人们意识到模拟系统的仿真编码其实是一个作用于离散时间间隔的输入和输出样本的数字信号处理系统。
After a while it was realized that the simulation coding of the analog system was actually a DSP system that worked on samples of the input and output at discrete time intervals.
