Rotates

例句:

• As the wheel rotates, its motion is communicated to a mechanical device which makes use of it to raise and lower a plunger, and hence as long as the wind turns the windmill, water is raised. 伯莎M.克拉克. 科学通论.
• Usually a delicate pointer is attached to the movable coil and rotates freely with it, so that the swing of the pointer indicates the relative values of the current. 伯莎M.克拉克. 科学通论.
• When the current which enters at _B_ flows through the wire, the coil rotates, tending to set itself so that its north face is opposite the south face of the magnet. 伯莎M.克拉克. 科学通论.
• But the speed with which _W_ is raised is only one third the speed with which the small wheel rotates, or increase in power has been at the decrease of speed. 伯莎M.克拉克. 科学通论.
• A general circulatory motion is in fact established ultimately in one direction about the central mass, which receiving new particl es from the encircling current rotates in harmony with it. 李贝. 西洋科学史.
• As long as the coil rotates between the poles of the magnet, current flows. 伯莎M.克拉克. 科学通论.
• As a result the coil rotates continuously, and produces motion so long as current is supplied from without. 伯莎M.克拉克. 科学通论.
• As the armature rotates, its motion is communicated by gears to the wheels, the necessary current reaching the motor through the overhead wires. 伯莎M.克拉克. 科学通论.
• A motor constructed in accordance with Section 309 would be of little value in practical everyday affairs; its armature rotates too slowly and with too little force. 伯莎M.克拉克. 科学通论.
• It is clear that a force applied to turn wheel 1 causes a slower rotation of wheel 3, and a still slower rotation of wheel 4, but as 4 rotates it winds up a chain and slowly raises _Q_. 伯莎M.克拉克. 科学通论.
• The coil and disks are supported by the strong and well-insulated rod _R_, which rests upon braces, but which nevertheless rotates freely with disks and coil. 伯莎M.克拉克. 科学通论.
• A small electrical motor 1, run by a storage battery or electric light wires, turns a belt 3, and rotates pulley 4 and a long horizontal cylinder 5 running beneath the keyboard. Edward W. Byrn. 十九世纪发明进展.
• A steam turbine wheel near the base turns a vertical shaft bearing at its upper end a pan which rotates within the outer case. Edward W. Byrn. 十九世纪发明进展.
• In that diagram, also, there is shown a cog-wheel, _h_, fixed on to the axis, and a small outer case, in which that wheel rotates. 弗雷德里克·科利尔·贝克维尔. 伟大的事实.
• If air is forced continuously against the disk as it rotates, a series of puffs will be heard (Fig. 177). 伯莎M.克拉克. 科学通论.
