本书由核辐射物理和辐射探测学两部分组成,构成了从辐射产生、辐射性质到辐射探测的完整体系。辐射物理部分包含了对原子核的基本性质、原子核的稳定性、核过程(包括核衰变、核反应和核裂变)发生的条件和概率、辐射与物质相互作用机制等问题的论述。辐射探测学则重点讨论探测器输出信号形成的物理过程、探测器输出回路与其工作状态的关系、统计涨落对探测器性能的影响等基本概念和共性的问题。两部分前后呼应、相互联系,有利于读者加深对辐射及其探测本质的了解,形成较为完整的概念。 本书可作为高等学校核科学与工程有关专业的教材,也可供从事核技术应用、核能科学与工程、核材料与循环及辐射防护工作的工程技术人员参考。
This highly regarded text provides an up-to-date and prehensive introduction to modem particle physics. Extensively rewritten and updated, this fourth edition includes all the recent developments in elementary particle physics, as well as its connections with cosmology and astrophysics. As in previous editions, the balance between experiment and theory is continually emphasized. The stress is on the phenomenological approach and basic theoretical concepts rather than rigorous mathematical detail. Short descriptions are given of some of the key experiments in the field, and how they have influenced our thinking. Although most of the material is presented in the context of the Standard Model of quarks and leptons, the shortings of this model and new physiceyond its pass (such as super symmetry, neutrino mass and oscillations, GUTs and superstrings) are also discussed. The text includes many problems and a detailed and annotated further reading list. This is a text suitable for final-year physics un
由中国科协学会学术部主办,云南省科协、云南大学、中科院云南天文台联合承办的第34期新观点新学说学术沙龙于2009年7月18~19日在昆明举行。本届沙龙的主题是“高能天体物理中的热点问题”,参加沙龙研讨的有来自中科院高能物理所、北京大学等著名科研院所和高校的30余位专家学者,就当今天体物理领域中的热点和前沿问题进行了充分的交流和探讨,使学术界对高能天体物理中的相关热点问题有了更深入的认识。 高能天体物理研究的是发生在宇宙天体上的高能现象和高能过程,涉及高能粒子的产生、加速、传播等。发生在这些天体上的高能物理过程不可能在地球上的实验室中实现,但所观测到的现象为人们研究条件下的物理过程提供了条件。近十几年来,随着地面大气切仑科夫探测器及空间x射线、伽玛射线探测器的不断投入使用,高能天体物理的研究

Recent years have brought a revival of work on string theory, which haeen a source of fascination since its origins nearly twenty years ago.There seems to be a widely perceived need for a systematic, pedagogical exposition of the present state of knowledge about string theory. We hope that thiook will help to meet this need. To give a prehensive account of such a vast topic as string theory would scarcely be possible,even in two volumes with the length to which these have grown. Indeed,we have had to omit many important subjects, while treating others only sketchily. String field theory is omitted entirely (though the subject of chapter 11 is closely related to light-cone string field theory). Conformal field theory is not developed systematically, though much of the background material needed to understand recent papers on this subject is presented in chapter 3 and elsewhere.
