We have used the words "mechanical life," "the mechanical kingdom," "the mechanical world" and so forth, and we have done so advisedly, for as the vegetable kingdom was slowly developed from the mineral, and as in like manner the animal supervened upon the vegetable, so now in these last few ages an entirely new kingdom has sprung up, of which we as yet have only seen what will one day be considered the antediluvian prototypes of the race.英文原著 · 《Canterbury Pieces》
Toward two o'clock he stood up, mind still absorbed, and mechanically started to undress. He then observed the roll of paintings Hunt had given him. Better for them if they were flattened out. Mechanically he removed string and paper. There on top was the Italian mother he had asked for. A great painting--a truly great painting. Mechanically he lifted this aside to see what was the second painting Hunt had included. Larry gave a great start and the Italian mother went flapping to the floor.英文原著 · 《Children of the Whirlwind》
Mechanically she obeyed; mechanically she looked down where his finger was pointing. It was the convict Monbrun--there, just visible under the bright light of the candle, were the fatal letters "T. F." branded on the villain's shoulder!英文原著 · 《AFTER DARK》
The Seventh went by boat to Annapolis. The same course was taken by a regiment of Massachusetts mechanics, the Eighth. Landing at Annapolis, the two regiments, dandies and laborers, fraternized at once in the common bond of loyalty to the Union. A branch railway led from Annapolis to the main line between Washington and Baltimore. The rails had been torn up. The Massachusetts mechanics set to work to relay them. The Governor of Maryland protested. He was disregarded.英文原著 · 《Abraham Lincoln and the Union》
The dynamo and the central power station brought the electric motor into action. The dynamo and the motor do precisely opposite things. The dynamo converts mechanical energy into electric energy. The motor transforms electric energy into mechanical energy. But the two work in partnership and without the dynamo to manufacture the power the motor could not thrive. Moreover, the central station was needed to distribute the power for transportation as well as for lighting.英文原著 · 《The Age of Invention》
By 1891 Langley had a model light enough to fly, but proper balancing had not been attained. He set himself anew to find the practical conditions of equilibrium and of horizontal flight. His experiments convinced him that "mechanical sustenation of heavy bodies in the air, combined with very great speeds, is not only possible, but within the reach of mechanical means we actually possess."英文原著 · 《The Age of Invention》
