摘 要：引力無(wú)處不在，卻又看不見，摸不著。人類最早從天體運(yùn)動(dòng)中接觸到引力，并由此逐漸深入。其中最為重要的引力理論是牛頓引力理論和愛因斯坦引力理論，前者首次揭開了行星運(yùn)動(dòng)之謎，使人類第一次認(rèn)識(shí)了宇宙，后者則更接近引力的本質(zhì)，預(yù)言了一系列引力效應(yīng)。本文為材料綜述類文章，對(duì)牛頓引力理論，愛因斯坦廣義相對(duì)論，以及二十世紀(jì)中后期的引力理論做了系統(tǒng)概括，對(duì)引力場(chǎng)，引力波，量子引力等方面做了總結(jié)，以期望給讀者對(duì)認(rèn)識(shí)引力的概念提供幫助。 關(guān)鍵詞：引力，引力理論，牛頓，愛因斯坦，廣義相對(duì)論，量子引力
Abstract: Gravity is everywhere, but it can not be seen and can not be touched. Humans understand the concept of gravity firstly from the movement of celestial bodies, since then people gradually research the concept. The most important theories of gravity is Newton gravitational theory and Einstein gravitational theory, the former first unveiled the movement of the planets, making human first met the mysteries of universe, the latter is more closer to the essence of gravity and predicts the series of gravitational effects. This paper reviews materials about gravity, making a summary for Newton and Einstein gravitational theory, and theory of gravity of the 20th centaury. And it also involves Gravitational field, Gravitational waves and Quantum gravity .It is expected to give readers help to understand the concept of gravity. Keywords: gravity, gravitational theory, Newton, Einstein, General relativity, Quantum gravity |
