grouinterval
track pitch
tracking pitch
Examples
- An indirect measuring method is introduced in this paper , which has been applied to the track pitch measurement on the master during cutting process by a laser - disc cutting machine
摘要主要介绍了一种间接检测方法，该方法用于检测光盘刻槽机所刻母盘上伺服槽的道间距。 - From a demand for further amount of aggregate transmission capacity , not only expanding an available wavelength range but also cramming frequency - spacing have been investigated
考虑到将来信息传输容量的急剧增长，因此不仅要拓宽可复用的波长范围，而且信道间距也需进一步降低。 - Generally , the designed channel spacing of itu - t standard in wdm systems is from 0 . 8nm to 1 . 6nm , which is much larger than the spacing required by actual communication bandwidth . for example in lightwave transmission systems , a sghz channel occupies only 0 . 04nm at the wavelength band of 1 . 55 n m . thus , most of the bandwidth in the actual transmission systems may be wasted
Itu - t标准中wdm系统设计的信道间距为0 . 8nm - 1 . 6nm ，这远远大于实际使用的信道带宽，例如一个带宽为5ghz的信道在1 . 55 m波段只占据了约0 . 04nm的波长范围，因而导致大部分的带宽被浪费。 - The paper introduces the principle of transient rayleigh wave exploration and the calculating process of f - k region analysis , according to experimental data analyzes the influences of the parameters on the calculation of phase speed of rayleigh wave and the various factors affecting transient state rayleigh wave exploration , at last , gives some advices on how to choose the best sampling rate , group interval , offset , vibrating source and receiver
