The successful investigations of r.f. effects in NGR were recently in progress [1–3]. The purpose of this paper is to pay attention to some new theoretical results in this field which may be an object of the experimental realization.  相似文献

The aim of this paper on the experimental research on gravitational waves is to stimulate the interest of the scientific community on this subject. In the following we try to stress the impact of this subject on fundamental physics, and the interdisciplinary aspects involved in the present experimental efforts. Details of current experiments will not be given. In sections 1- 8, we summarize the main features of gravitational waves and some of the principal astrophysical processes involving emission of gravitational radiation. In sections 9- 18, we review the detection principles, the intrinsic limits of the detectors and the peculiarities of the gravitational-wave data analysis.  相似文献

本文指出,只当u=ω/(kxve)≤2—2.5时,波驱动的电流以共振电子电流为主,波的耗散机制也主要是共振阻尼效应;而当u≥3时,非共振电子电流一般将超过共振电子电流,碰撞耗散也将大于共振耗散。波驱动电流所需功率较高,比相应欧姆功率大得多。这对反应器的设计带来困难,一般说来反应器中选取u≤2.5的共振电子电流较为合适。波驱动电流时将出现等离子体旋转,除环向旋转外,还将引起较大的角向旋转,后者伴有较大的径向电场。 关键词:  相似文献
