It is the intention of this paper to explain the basic principles of synthetic elastometry and the methods of repeated trials with the 「Elastic Frictoinal Tester of Filament Yarn」.
本文主要说明长丝纱线弹性综合测定的原理和用长丝纱线弹性摩擦系数测试仪进行定延伸率重复测试的方法。
After repeated trials the outcome was essentially always similar.
在多次试验后结果本质(benzhi)上总是相似(xiangsi)的。
But after repeated trials of the same stimulation, 30 seconds apart, the fetus gets used to the sound and doesn't react.
