英语词汇vernier的起源、历史背景-英语词源词典

vernier; vernier caliper, etc. A vernier is any small, auxiliary movable scale attached to another graduated instrument. It is often attached to the transit, sextant, quadrant, and barometer for very accurate measurements. French mathematician Pierre Vernier (1580–1637) invented the scale, describing it in a trea- tise he wrote in 1631. Vernier was commandant of the castle in his native town of Ornans in Burgundy and later served the king of Spain as a counselor. His invention estimates the near- est 10th of the smallest division on the scale it is attached to. It was originally an improvement on a scale called the nonius, in- vented by the Portuguese scientist Nunez, and proved to be a milestone in the techniques of precise measurement. The ver- nier caliper, the vernier compass, both incorporating verniers, and the vernier engine, a small rocket engine that corrects the heading and velocity of a long-range missile, also bear the French inventor’s name.
