• Steam admitted into the globe from the cauldron escaped through the side pipes, and its pressure on these pipes caused the globe to rotate. 威廉·亨利·杜利特. 世纪发明.
• During the motion of the coil, a strong deflection of the galvanometer is observed; but the deflection ceases as soon as the coil ceases to rotate. 伯莎M.克拉克. 科学通论.
• Proper reversals of the current are accompanied by continuous motion, and since the disk and shaft rotate with the coil, there is continuous rotation. 伯莎M.克拉克. 科学通论.
• The wind strikes the sails, and causes rotation; and the stronger the wind blows, the faster will the wheel rotate. 伯莎M.克拉克. 科学通论.
• Finger pawls, working into ratchets at the ends of the roller, serve to rotate it after each line is printed. Edward W. Byrn. 十九世纪发明进展.
• The wheel and axle consists of a large wheel and a small axle so fastened that they rotate together. 伯莎M.克拉克. 科学通论.
• But the stronger the current through the coil, the stronger will be the force tending to rotate the coil, and hence the less effective will be the hindrance of the twisting string. 伯莎M.克拉克. 科学通论.
• Let it suffice h ere to state that Rutherford assumes that the greater mass of the atom consis ts o f negatively charged particles rotating about a positive nucle us. 李贝. 西洋科学史.
• The surplus water is best removed by centrifugal pumps, since sand and sticks which would clog the valves of an ordinary pump are passed along without difficulty by the rotating wheel. 伯莎M.克拉克. 科学通论.
• This machine contains a number of rotating beaters and high-pressure streams of water. 佚名. 神奇的知识之书.
• When rotating at the rate of 788 revolutions in a minute, and lifting the water 19·4 feet, the greatest practical effect, compared with the power employed, was attained. 弗雷德里克·科利尔·贝克维尔. 伟大的事实.
• Subsequent changes involved the rotating of the cylinder instead of the wheels and many modifications in the form of the wheels. 威廉·亨利·杜利特. 世纪发明.
• It has six chambers in the rotating breech, and is furnished with a barytes lock and one priming pan, to fire all the chambers. 弗雷德里克·科利尔·贝克维尔. 伟大的事实.
• If a mirror or any other polished surface is held in the path of a sunbeam, some of the light is reflected, and by rotating the mirror the reflected sunbeam may be made to take any path. 伯莎M.克拉克. 科学通论.
• The chalk was rotated by hand. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• In this instance, also, the breech is rotated by hand. 弗雷德里克·科利尔·贝克维尔. 伟大的事实.
• A vertical shaft D is rotated constantly by a band on pulley _d_. Edward W. Byrn. 十九世纪发明进展.
• The record is constantly rotated until its entire surface is coated. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• Although the weight is estimated at several tons, so sensitive is its poise on the mercury that the enormous lantern may be easily rotated by the pressure of one’s finger. Edward W. Byrn. 十九世纪发明进展.
• The revolving disk-shaped cutter E is rotated by a pulley and belt from a drum, which latter is made long enough to accommodate the travel of the frame. Edward W. Byrn. 十九世纪发明进展.
• This, when rotated about its diameter, to bring alternately the bird and cage into view, appears to bring the bird into the cage, or to put the rider on the horse’s back, as the case may be. Edward W. Byrn. 十九世纪发明进展.
• 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.
