we are now in a position to introduce tidal forces . 現(xiàn)在我們可以導出潮汐力了。
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為熱能,使溫度提高,甚至可達數(shù)百萬度。
