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.

这个频率梳理装置由一束产生一系列非常短，空间上平均分布（就好象梳齿一样）、频率上广泛分布的光脉冲产生的。

A sine wave alternating voltage signal is generated synchronously in the presence of gear teeth made of carbon steel, magnetic stainless steel, or iron (ferrous metal).

阿正弦波交流电压产生的同步信号中的齿轮碳钢，不锈钢磁性，或铁(黑色金属)提出的存在。

In small tooth difference of inner meshed transmission, there were a few pairs of tooth faces which were apart from each other for a small gap beside the contact point generated by two meshed teeth.

在少齿差内啮合传动中，存在多对接近啮合的小间隙齿面于理论啮合点左右，轮齿受力产生的微小变形使得某些对齿面相互接触进入啮合状态。
