In addition, NIST has shown that extremely stable microwave signals can be generated from optical frequency combs.
另外，NIST还发现可以从光学频率梳产生非常稳定的微波信号。

When distribution statistics are generated for the column "TYPE," the optimizer knows the real frequency of each model.
而一旦生成了关于“TYPE”列的分布统计信息，优化器即可了解每种型号真正的出现频率。

The frequency comb is generated by a laser that produces a series of veryshort, equally spaced pulses of light (like the teeth of a comb) across a broadspectrum of frequencies.
