摘要:
In terms of universality, few physical processes rival magnetic reconnection. It is thought to be responsible for a wide variety of astronomical, solar, and laboratory plasma phenomena. In astrophysics, for example, transient emissions from compact X ray sources in binary systems are thought by some to originate in magnetic reconnection between a neutron star's magnetosphere and the surrounding accretion disk. In solar physics, it has long been thought that magnetic reconnection is at the root of the enormous energy release found in flares, and may also play an important role in causing coronal mass ejections. At the opposite extreme of size scales, laboratory plasma experiments show that magnetic reconnection is important in the stability, and instability, of reverse field pinches, spheromaks and tokamaks.

摘要:
Despite 25 years of environmental legislation, many Americans are drinking and fishing in water that does not meet public health standards. On June 11, the Environmental Protection Agency (EPA) released a report entitled “Environmental Indicators of Water Quality in the United States” which documents U.S. water w

摘要:
Earth observations from space are one of the great successes of the space age. However, because the promise of this technology is a long way from being realized, the joy of success is tinged with disappointment for both researchers and operational users of the data. U.S. Earth observation programs have been in turmoil since their inception, with confusion coming to a crescendo over the past 6 years. Neither the executive or legislative branches of the government have shown that they can successfully manage this technological capability created by the space program.

摘要:
A joint Japanese‐French program (New STARMER) sampled active hydrothermal sites near the New Britain active subduction zone in the South Pacific from October 16 to November 13, 1995. Using theR/V Yokosukaand the submersible Shinkai 6500, researchers made a number of surprising findings about magmatic, tectonic, and hydrothermal activity at the central and northeastern ridges of the Manus Basin spreading system. Fifteen dives by the submersible revealed a spectrum of hydrothermal processes, ranging from shimmering waters to black smokers. For the first time, highly acidic fluids rich in H2S and low in temperature (87–118°C) were sampled in the eastern part of the Manus B

摘要:
Recent studies indicate that magnetopause reconnection can, at times, occur exclusively as a series of separated, short bursts. Reconnection generates “open” magnetic flux that threads the magnetospheric boundary, the magnetopause, and so connects the magnetosphere with interplanetary space. The rate at which open flux is generated by a line of unit length in the magnetopause is called the reconnection rate. By Faraday's induction law, the reconnection rate is a boundary‐tangential electric field, Et, along that line (called an X
