length variation meaning in Chinese

长度偏差

High fiber length variation and immature fibers
纤维长度差异大和未成熟纤维含量高。
In precision length measurement , the environmental factors will not only cause the length variation of the measured object , but also influence the characteristic of laser ’ s measurement system and other metrical tools . thereby the measurement result is considerably influenced and it makes the precise measurement no sense
在精密长度测量中,测量环境温度的变化不但会使被测件的长度发生变化,而且还会影响激光测量系统,量块等测量工具的特性参数,给测量结果造成较大的影响,使精密测量失去意义。
