We see neutron stars principally by their radio and X-ray emission. Their appearance in these different bands depends on whether the emission comes from the surface or its magnetosphere. New phenomena continue to be found from neutron stars, which makes it an exciting and topical research area. This volume is a collection of the papers from a NATO Advanced Study Institute held in Italy in October 1996. Many, and for me the most interesting ones, are substantial reviews on topics such as Pulsar magnetic fields and glitches (M. Ruderman), Radio pulsar population properties (D. Lorimer), Gamma-ray emission from CGRO pulsars (G. Kanbach), Neutron stars and black holes in X-ray binaries (J. van Paradijs), Kilohertz quasi-periodic oscillations in low-mass X-ray binaries (M. van der Klis), Thermonuclear burning on rapidly accreting neutron stars (L. Bildsten), On the X-ray emission properties of rotation powered pulsars (W. Becker and J. Truemper). It will serve as a useful reference and source book for students in high energy astrophysics and related fields. The high price may deter its purchase by individuals, but it will be a good volume for a library needing recent coverage on neutron stars. It does not of course include the most recent developments on anomalous X-ray pulsars or magnetars. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

The reviewed Volumes of the AAA series record, summarize and index nearly 12 000 papers covering all aspects of astronomy and space sciences, published throughout the world during the first half of the year 1998. The AAA series is the most important source of information on progress in the scientific disciplines. They have become an indispensable source of information for scientists and students involved in the Universe research. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

通过用一组非线性方程组来逼近线性规划的Kuhn-mcker条件方程,从而将求解线性规划问题转化为一个用Newton迭代法来求解非线性方程组的问题。经数值计算表明,该算法在一般情况下能实现快速收敛。  相似文献

A biography of John Alvin Pierce is given, starting with his early interest in radio. Pierce received his amateur license and operated a spark transmitter at the age of twelve. His amateur activities led to work at the Cruft Laboratory of Harvard University under the supervision of Professor H.R. Mimno. This association with the Cruft Laboratory has continued to the present day with few interruptions. Pierce's work with different groups and in various areas is sketched, focusing on his work with Loran  相似文献
