We observed a doublepeak in the differential resistivity as the driving current increases, which corresponds to a two-step depinning in the vortex motion.
观察到随着外驱动力的增大微分电阻出现两个尖峰，它对应着磁通运动存在两次退钉扎现象。

A practicable solution to the angle-digital conversion of synchro is provided, which includes cut section coding for the ratio of sine to cosine and sampling on doublepeak value.
针对自整角机的轴角数字转换，提出了分区间正余弦信号相比较编码和双峰值采样的方法。

At its peak in 2007 it was worth some $65 billion, reckons Clare McAndrew, founder of Arts Economics, a research firm—double the figure five years earlier.
Arts Economics 研究公司的创始人克莱尔·麦克安德鲁估算，在2007年的巅峰期，它的价值约为650亿美元，是五年前的两倍。
