(2007) Temperature and composition of the Earth's core. Contemporary Physics 48, 63-80.Alf`e, D., M. J. Gillan, and G. D. Price (2007), Temperature and composition of the Earth's core, Contemporary Physics, 48 (2), 63-80, doi:10.1080/00107510701529653....
THE temperature distribution in the Earth's core places important constraints on the Earth's internal heat budget and on models of the geodynamo. The solid inner core crystallizes from a liquid outer core, consisting mainly of iron alloyed with a lighter element, at a depth of about 5,100 k...
aRecall that changes in inflow temperature are the main source of temperature fluctuations in the tank. To reject such disturbances, an alternative to feedback control is the feedforward architecture shown below: 召回在流入温度上的变化是温度波动的主要来源在坦克。 要拒绝这样干扰,选择到反馈控制如下所...
根据后文of over 7,000˚C以及句意“温度”可知,应填名词temperature,作宾语,上文冠词a提示,此处应用单数形式。故填temperature。 (2)题详解: 考查形容词。句意:地核周围是一层厚厚的地幔,它的下部是固体岩石,上部是熔化的岩石,称为岩浆。修饰后文名词the core且表示“周围”,应用形容词surrounding,句首单词...
Quentin Williams, associate professor of earth sciences at the University of California at Santa Cruz offers this explanation
A. The core is mainly made of rocks B. The core is completely liquid C. The core is divided into inner core and outer core, and the inner core is solid while the outer core is liquid D. The core has the lowest temperature in the E. arth ...
The density of the Earth's core is 8–10% less than that of pure iron at the same pressure and temperature and this is usually interpreted as implying the existence of a substantial amount of light element(s) in the core. Many possibilit... STEVENSON,J D. - 《Nature》 被引量: 67发...
Temperature of the inner-core boundary of the Earth: Melting of iron at\n high pressure from first-principles coexistence simulations The Earth's core consists of a solid ball with a radius of 1221 Km,surrounded by a liquid shell which extends up to 3480 Km from the centre of theplanet, ...
Although the majority of the outermost core remains actively convecting, sufficiently large and strong regional inversion layers produce a one-dimensional temperature profile that mimics a globally stratified layer below the core–mantle boundary—an apparent thermal stratification despite the average heat ...
