iron core

基本解釋

The planet's magnetic field is generated by the motion of molten iron flowing around a superhot, solid iron core.
地球內(nèi)部的熔鐵圍繞其核心的超高溫固體鐵核流動(dòng)，由此產(chǎn)生了地球磁場(chǎng)。
The notion that the moon has an iron core with a layer of molten iron surrounding it isn't new. But evidence so far has been indirect.
月球里有著周圍帶有融化鐵層的鐵芯的這個(gè)概念并不是新的。但到目前為止，這些證據(jù)都是間接的。
Our understanding of planet formation suggested that precious metals such as gold and tungsten should have moved into Earth's iron core long ago, due to the affinity they have for bonding with iron.
我們對(duì)地球形成的理解認(rèn)為如黃金和鎢等貴金屬在很久以前因它們與鐵粘合的吸引力而移到了地球的鐵核心。令人驚訝的是，在地球表面和下面的地幔層里貴金屬反而比較豐富。

The magnetometer will record what, if any, magnetic field the asteroid has, thus revealing whether it was ever part of an object large enough to have possessed the molten iron core needed to generate such a field.

Results show that the electric machines designed by using the presented package has shorter iron core and better Performance.
結(jié)果表明：用這個(gè)系統(tǒng)設(shè)計(jì)的電機(jī)具有較好的性能及較短的鐵心長(zhǎng)度。

Since 2003, the performance of International Dry and Bulk market was very powerful. The demand based on the importation of China's iron core and Japan's coal rises sharply, while trade of corn and minor bulk is also very active.
國(guó)際于散貨航運(yùn)市場(chǎng)自2003年以來表現(xiàn)十分強(qiáng)勁,以中國(guó)進(jìn)口鐵礦石和日本進(jìn)口煤炭為核心的海運(yùn)需求空前高漲,谷物和小宗散貨海運(yùn)貿(mào)易也十分活躍,從運(yùn)力供給看,歷史罕見的壓港和低增長(zhǎng)的新交船使運(yùn)力供應(yīng)高度緊張,而究其原因,此番市場(chǎng)行情高峰從根本上說是國(guó)際干散貨航運(yùn)市場(chǎng)上需求的增長(zhǎng)不能被及時(shí)滿足所造成的。
