【摘要】：本文綜合核物理、天文和地質(zhì)學(xué)的最新研究成果,推導(dǎo)出在45億年前太陽系的全部原始類地行星及其某些衛(wèi)星(包括地球及月球)上,發(fā)生過大規(guī)模的、持續(xù)的鈾、钚鏈式核裂變,釋出了巨大的熱能,熔化了整個原始星球。新星球的物質(zhì)發(fā)生了重力分異作用、形成了按密度劃分的圈層結(jié)構(gòu)。地球中心是內(nèi)地核,在高壓下壓成了固態(tài)。鈾、钚下沉到內(nèi)地核頂部停留,繼續(xù)發(fā)生鏈式核裂變,但改變不了內(nèi)地核的固態(tài)性質(zhì)。從此處產(chǎn)生的核裂變能,主要以熱對流的形式外導(dǎo)。直到前45億年以后,鈾的鏈式核裂變停止了,只剩下钚的鏈式核裂變,生成的熱能減少了,地球開始冷凝。當(dāng)熔漿表面溫度下降到700~800℃時,較輕的花崗巖質(zhì)巖漿首先凝固成薄層。它很脆弱、經(jīng)不起大風(fēng)浪和潮汐力的沖擊,破碎成小塊,隨著下面對流的玄武巖質(zhì)熔漿匯集起來,形成大片飄浮物,后來就成為大杧;小片的便成為島嶼。溫度逐漸下降,地幔冷凝成固體。溫度下降至100℃以下,大氣中的水蒸氣冷凝成水,下落匯集在地表低凹處,便有了海洋和湖泊。所以海洋底主要分布著玄武巖。從內(nèi)地核頂部不斷產(chǎn)生的核能以"地幔柱"的形式穿過固體地幔,上升至地殼。受堅硬地殼的隔擋、便集中在地殼下構(gòu)成軟流層。當(dāng)?shù)貧�巖石受熱軟化和可以流動之后,便開始向壓力小的方向流動。又受日、月引力和地球自身自轉(zhuǎn)力的作用,軟流層的動能又有了增強。這種巨大的能量支配了地殼的升降、褶曲、斷裂、變質(zhì)、巖漿、火山和地震等活動。地球是天體之一,無時不受自然界各種作用力的影響,但支配它演化的主要作用力是核能。本文還簡述了核能、核素與太陽系星體演化的關(guān)系。
[Abstract]:Based on the latest research results in nuclear physics, astronomy and geology, this paper deduces that massive and persistent uranium occurred on all primitive terrestrial planets in the solar system and some of their moons (including the Earth and the Moon) 4.5 billion years ago.Plutonium-chain fission emits enormous heat and melts the entire primordial planet.The matter of the new planet is separated by gravity, forming a stratified structure by density.The center of the earth is the inner core, pressed into solid state under high pressure.Uranium and plutonium sink to the top of the inland nuclear and continue to produce chain fission, but do not change the solid nature of the inland nuclear.The nuclear fission energy generated here is mainly extrapolated in the form of thermal convection.Until 4.5 billion years ago, the chain fission of uranium ceased, leaving only plutonium chain fission, resulting in less heat, and the Earth began to freeze.When the surface temperature of the magma drops to 700 ~ 800 鈩，
