从QED中光子传播子的Schweinger-Dyson方程出发,得到一个有用的德拜质量和热力学压强之间的关系.利用这个关系以及有限温度与有限化学势下的相关压强计算了德拜质量的双圈修正.其结果显示双圈修正减少了德拜屏蔽质量.最后还讨论了QED等离子体中的磁质量.

A major obstacle to the broad application of cathodic arc plasma deposition is the presence of macroparticles. In this paper, the properties of the large rectan
Let A be the mod p Steenrod algebra for p an arbitrary odd prime. In 1962, Liulevicius described hi and bk in Ext*,A*(Zp, Zp) having bigrading (1, 2pi(p- 1)) an
In this paper, the stability of stochastic Hopfield neural network with distributed parameters is studied. To discuss the stability of systems, the main idea is
A new algorithm-ModEn (mode entropy) is proposed by analyzing and modifying ApEn (approximate entropy), so that the irregular analysis can be applied to the tim
分别从材料、结构、尺寸等方面全面地研究了Halbach结构六极永磁铁的设计方法.针对个别磁块可能存在的退磁问题给出了相应的解决方案.通过优化结构,使六极磁铁在离子源等离子
Jockusch, Li and Yang showed that the Lown and Low1 r.e. degrees are not elementarily equivalent for n ＞ 1. We answer a question they raise by using the results
The outcome of the Apollo lunar exploration program 1969-1974 was a model of lunar petrogenesis which ignored the probability of selective volatilisation of gas
In this paper we give the (Lpα, Lp) boundedness of the maximal operator of a class of super singular integrals defined by T*Ω,αf(x) =- supε＞ 0|∫|x-y|＞εb(|y|
