small frequencies

In very small amounts throughout the eons were these frequencies of information brought onto this planet.

以少量的全部永世就是把这些频率带到这个行星上.

And the results of the four field tests on the structural damping and natural frequencies of the tainter gates are introduced, which are necessary for judging the dynamic instability of the tainter gate and show that the structural damping of the barrage tainter gates is very small.

给出了判断动力失稳所必须的弧形闸门结构阻尼比的原型观测结果，它表明表孔弧形闸门的结构阻尼比是很小的。

The corrugation mainly contains the same wavelength as a sleeper bay and 28-35 mm wave-lengths. The undulatory wear with 28-35 mm wave-lengths and very small depth trough is caused by a contact vibration of the wheel and rail at high frequencies;

这类钢轨波磨具有与轨枕间距几乎相等的波长和28&35mm的短波长，这个短波长不均匀磨损主要是由轮轨高频接触振动引起；

Low scanning frequencies lead to quite small phase difference between base plate signal and reaction mass signal.

当扫描频率较低时，平板的运动相位与重锤信号相位的差别较小；
