The thermal sensor can be used to monitor the thermal response of the subject and for determining the temperature of the outer periphery. 额外地或备选地,可以确定核心体温. Additionally or alternatively, you can determine the core body temperature....
The outer boundary is electrically insulating, the inner core has the same electrical conductivity as the outer core. The inner core temperature is kept constant at T = 5.434, the gradient of temperature on the outer core equals to −2/(1 − c). A uniform heat source with ε...
The inner core of the Earth is _. A. Cooler than the outer core B. At the same temperature as the outer core C. Warmer than the outer core D. Has no temperature difference with the mantle 相关知识点: 试题来源: 解析 C。解析:地球的内核比外核温度更高。随着深度增加,地球内部温度升高,...
Averaging over a timescale that is long compared to that associated with convection but short compared to the evolutionary timescale of the planet it is assumed that convection mixes the entropy and light elements uniformly throughout the outer core such that the temperature varies adiabatically. ...

2002). The crystallising (i.e., liquidus) temperature of a Si-bearing iron system is important for constraining the temperature at the inner core-outer core boundary (ICB, at 330 GPa). In this study, the mixing properties of Si-bearing iron phases are first examined by thermodynamic ...
1. Mechanically, it can be divided intolithosphere,asthenosphere, mesospheric mantle, outer core, and the inner core. 2. Chemically, Earth can be divided into thecrust, upper mantle, lower mantle, outer core, and inner core. How to inferred that earth has different layers?
Distributions of the outer core (d–g), the LVZ (h–k) and the mantle (l,m). Black and dashed grey lines correspond to the median and the 25th and 75th percentiles, respectively. Extended Data Fig. 4 Behaviour of the k2 and Q ratio over the tidal periods. The Delaunay arguments F ...
Earth’s magnetic field is generated by turbulent motion in its fluid outer core. Although the bulk of the outer core is vigorously convecting and well mixed, some seismic, geomagnetic and geodynamic evidence suggests that a global stably stratified layer exists at the top of Earth’s core. Su...
At the center of the Earth lies a two-part core. "The inner part is about the size of our moon," Marone says, "and has a density of essentially steel." The outer core surrounding it is an ocean of liquid metal 2,300 kilometers thick. The Earth's rotation makes this ocean flow an...
