《软物质物理导论》(编者周鲁卫)第一章介绍软物质物理的概貌。第二章探索组成软物质材料基本单元之间的相互作用。本书比较注意实验的叙述与实验思路发展和实验手段发展的叙述。软物质较多以轻元素组成，而像氢、碳、氧、氮等等轻元素的中子散射截面比X光散射截面大很多，而我国正在积极建设散裂中子源的大型科学项目，小角散射对软物质又是格外重要的一种手段。所以本教材在第三章中着重介绍怎样用中子散射，特别是小角中子散射获得软物质的结构。

"Introduction to Soft Matter Physics"(Writer Zhouluwei)was developed over a period of 10 years for the author's lecture on soft matter physics for both graduate and undergraduate students in the Physics Department of Fudan University.Soft matters are different from hard ones essentially due to former's relatively weak interaction which is comparable to kBTrm(Trm=room temperature). "Introduction to Soft Matter Physics" is this feature that results in the major characteristics of soft matters such as "strong reactions upon weak actions". This textbook not only concentrates on the basic interactions inside soft matters in a reductionist approach(Chap. 2, Chaps. 5 and 6), but also introduces the exploration works on the complexity of soft matters in methods of system science(Chap. 4). Soft matters is a bridge between hard matters and complex systems that show characteristics of deterministic chaos in nature.As a "model animal"(a mouse, if you prefer) in soft matters,electrorheological(ER) fluids are introduced. While the properties and mechanisms of static ER effect are summerized(Chap. 5), this textbook puts its emphasis on the dynamic ER effects(Chap.6). The Onsager principle of least energy dissipation rate is adapted in the textbook to see how it governs the optimal paths of a system's deviation from and restoration to equilibrium. As another model animal, granular media is introduced(Chap. 7) to explain the thermodynamics of sands and its dynamics such as compartmentalization, pattern formation, and granular flow. Since many soft matters consist of light atoms, neutron scattering appears useful as a powerful tool and is worth mentioning(Chap.3),especially when a splashing neutron source is being erected in China.Soft matter physics is full of unknowns(Chap. 1) as the subject is still at its infancy, making it highly attractive. If you like a challenging subject, you will most certainly fall in love with soft matter physics at first sight!
