“hot spot”的概念、定义、翻译、参考文献-科学参考

hot spot

Astronomy

1. A compact, highly luminous region (often called a bright spot) in a cataclysmic binary, located either where the stream of material hits the edge of the accretion disk, or at the inner edge of the disk. There may be small-scale flickering or larger variations in luminosity depending on fluctuations in the rate of mass transfer. The presence of a hot spot is often indicated by a hump in the orbital light-curve.

2. A small, bright region in a lobe of a radio galaxy. It is believed to be the site where high-velocity material in a jet collides with the leading boundary between the lobe and the surrounding intergalactic medium.

Internet

A part of a system which is heavily used or executed. For example, programs have hot spots that are regions of code which are frequently executed; networks also have hot spots (known as choke points) where traffic is at its heaviest.

Electronics and Electrical Engineering

A small portion of an electrode or circuit that is at a higher temperature than the rest of the electrode or circuit.

Geology and Earth Sciences

An area of high volcanic activity. Some hot spots, e.g. Iceland, are located on constructive margins. Others occur within lithospheric plates, often lying at the end of a chain of progressively older volcanoes, e.g. the Hawaiian-Emperor Chain. The hot spot is thought to be stationary, or nearly so, and to produce volcanoes intermittently as the plate moves over it. It has been suggested that mantle plumes lie beneath hot spots.

Geography

An area of localized swelling and cracking of the Earth’s crust caused by upwelling magma; deep-seated thermal anomalies fixed with respect to the surrounding mantle (Morgan (1972) GSA Memoir 132). Plumes from the lower mantle rise to the surface, forming volcanoes. As plates move over the Earth’s surface, the volcanoes delineate and record the history of plate motion, and the radiometric age of seamounts should show a simple progression away from the present-day hot spot locations. See Wessel and Kroenke (1998) Earth & Planet Sci. Letts 158, 1–2 on the relationship between a hot spot and its seamounts.
