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.

本书系统地总结了冲击波压缩科学在力学、物理和化学方面的研究成果，从冲击波压缩的基本概念出发，讲述了冲击波压缩科学的起源、良性学说和灾变学说，冲击波压缩下固体的弹性、塑性、加载波和卸载波等力学响，应，固体的压电、铁电、铁磁、电阻率、电极化等物理性质，以及冲击波压缩下固体的活化、改性、化学合成等化学效应。本书从力学、物理和化学的多学科角度，阐述了固体的强度效应、局域变形、高浓度缺陷等特性在冲击波压缩过程中的意义，介绍了冲击波压缩科学的发展方向。 本书可作为力学、物理、化学、材料科学、地球和天体科学等专业高年级本科生和研究生的参考书，也可供动高压物理、爆炸与冲击动力学研究领域的科研人员参考使用，对国防、民用工程和新材料开发领域的工程技术人员有着重要的参考价值。

本书内容涵盖粒子物理基础、宇宙线的物理（加速、相互作用）和天文（起源、传播）问题及其探测方法。针对目前广为采用的大气簇射实验，本书侧重讨论了大气簇射中宇宙线各成分（包括强子、光子、μ子和中微子）的理论模型及数值模拟方法。书中的理论分析简明直观，密切结合实验，具有较强的针对性。读者通过本书可以对宇宙线这个学科有整体和适当深度的了解。本书适合作为物理学专业高年级本科生和研究生的入门教材。对粒子物理标准模型和天文学有基础性的了解有助于对本书的理解。本书亦适合工作在宇宙线领域的专家学者参考。

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
