內地核かく

地球ちきゅう的てき內核，是ぜ地球ちきゅう的てき最深さいしん層そう的てき部ぶ份，半徑はんけい1220公里くり^[1]^[2]。一般いっぱん相しょう信しん它以鐵てつ-鎳之これ合金ごうきん組成そせい，以及大概たいがい與あずか太陽たいよう表面ひょうめん溫度おんど相しょう同どう，約やく為ため5700開ひらく氏し度ど。

温度おんど与あずか压力[编辑]

内地ないち核かく的てき温度おんど与あずか压力可か以通过理论与试验方式ほうしき估计出で铁在内ない地核ちかく与あずか外地がいち核かく边界压力（约330 GPa）时的融とおる化か温度おんど。温度おんど估计为5,700 K（5,400 °C；9,800 °F）。^[3] 内地ないち核かく的てき压强略りゃく高だか于内外地がいち核かく边界：估计在ざい330至いたり360吉きち帕斯卡（3,300,000至いたり3,600,000標準ひょうじゅん大氣たいき壓あつ）。^[4]铁在这么高だか的てき压力下か是ぜ固体こたい，因いん为其熔点随ずい压力戏剧性せい增ぞう高だか（参まいり见克かつ劳修斯－克かつ拉ひしげ佩龙方かた程ほど）。^[5]

Science杂志上じょう的てき一いち篇へん论文 ^[6]认为内ない地核ちかく边界铁的熔点是ぜ6230 ± 500 K。
