We are now in a position to introduce tidal forces . 現(xiàn)在我們可以導(dǎo)出潮汐力了。
Study on tidal force in gravitational field 引力場中潮汐力的研究
Paleontological clock; earthmoon system; extraterrestrial impact; tidal force torque 古生物鐘地月系統(tǒng)撞擊事件引潮力力矩
Very few science fiction stories picture humanity as a passive species, allowing the tidal forces of nature to flow unperturbed 很少的科學(xué)小說故事描繪人類像一個消極的人種,允許自然潮水的力量淹沒鎮(zhèn)靜。
The tidal force of the orbiting material converts its own kinetic energy into heat, thus heating it up to a temperature as high as a few million degrees 這運行中吸積物的潮汐力將動能轉(zhuǎn)為熱能,使溫度提高,甚至可達(dá)數(shù)百萬度。
The model is accurate and of great efficiency . ( 2 ) a numerical experiment concerned with the 3-d unsteady flow in a rectangular channel driven by tidal forcing at the open boundary has been done (2)模擬了在矩形水域中傳播的潮汐的情況,并與解析解進(jìn)行了比較,驗證了模型的合理性。
The tidal force of the moon has been slowing down the rotation of the earth, making the change of day and night rhythm infrequent . all these are conducive to evolution of life ,令氣候的變化不會出現(xiàn)太大的起伏而由月球產(chǎn)生的潮汐力也令地球自轉(zhuǎn)逐漸減慢,日夜交替不至太頻密,這些都有利生物的進(jìn)化。
The rotational changes arise because of tidal forces exerted by the moon and inertial effects related to the liquid outer core sloshing around and to the cycle of evaporation, in which water at the equator gets deposited at the poles as ice that melts seasonally 自轉(zhuǎn)的改變則因為月球產(chǎn)生的潮汐力,以及因地球外核液體攪動和大氣蒸發(fā)循環(huán)(赤道蒸發(fā)的水氣于地極凝結(jié)成冰,并周期性融化)產(chǎn)生的慣性效應(yīng)。
