The method of μSR is briefly described and its potential in the field of solidstate physics (especially metal physics) is
discussed. Some examples from the fields of magnetism, spin relaxation and particle diffusion in metals are shown and comparisons
with conventional hyperfine interaction methods are made for some areas of application. 相似文献

Light-front dynamics(LFD) plays an important role in the analyses of relativistic few-body systems. As evidenced from the recent studies of generalized parton distributions (GPDs) in hadron physics, a natural framework for a detailed study of hadron structures is LFD due to its direct application in Minkowski space as well as its distinct feature of accounting for the vacuum fluctuations in quantum field theories. In the last few years, however, it has been emphasized that treacherous points such as LF singularities and zero-modes should be taken into account for successful LFD applications to hadron phenomenology. In this paper, we discuss a typical example of the contemporary relativistic hadron physics in which the fundamental issues should be taken into account for the successful application of LFD. In particular, we focus on the kinematic issue of GPDs in deeply virtual Compton scattering (DVCS). Although this fundamental issue has been glossed over in the literature, it must be taken care of for the correct analysis of DVCS data. 相似文献

信息技术与课程整合是信息时代下教育教学发展和进步的必然要求,在这一背景下TPACK理论(整合技术的学科教学法知识)恰好为广大基础教育工作者进行信息技术化教学提供了坚实的理论基础.由于高中物理课程的有关特点,该理论对于物理学科的教学具有更加深刻的指导意义,因此本文从3个方面探讨了TPACK理论在高中物理教学中应用的必要性,研究了TPACK理论的应用策略,并以"自由落体运动"为例进行了TPACK体系分析,希望为TPACK理论在高中物理教学中的应用提供一些参考. 相似文献

“物理教育研究”是物理学的一个新学科分支,诞生于美国,研究的是物理学习的过程以及教学活动如何影响该过程。它采用科学的方法探测、甄别学生学习物理课程中普遍存在的共性困难,揭示学习物理知识的动力学过程,评价学习效果,并在此基础上建立关于物理学习的认知理论,用于开发新课程、新教学方法和新的教育研究工具。在美国国家自然科学基金的资助下,美国的“物理教育研究”这一新的学科分支迅速成长,取得了较多进展,并且将研究成果应用于美国高等学校的物理教学之中。在中国,“物理教育研究”还是一个相对陌生的研究领域。文章概述了“物理教育研究”在美国的发展历史与取得的进展,以及它如何促进美国大学物理教学的进步,希望该文能为发展中国的物理教育和提高中国的物理教学质量提供有益的参考。 相似文献

The present review deals with coherent states, its application to various problems in physics, chemistry and biology and its important applications to anharmonic, time-dependent and damped oscillator systems. It is seen that use of these states overcomes certain theoretical difficulties. 相似文献

Conclusion The application of lasers to nuclear physics is an extremely lively and Interesting area of research in physics. In the few years that have passed since its development, a large number of beautiful experiments have been performed. Most of the experiments have been performed at ISOLDE. For the next years, optical spectroscopy will continue to play a key role for a determination of spins, moments and charge radll of nuclear ground or isomeric states. 相似文献
