摘　　要：简要介绍了金属胶体纳米材料奇特的电磁、光学、催化、理化及传输等性质,主要包括：电磁性质、强度性质和可塑性、传输性质,以及催化和光学性质等。这些性质的应用前景、理论解释及当前的研究进展,同时从胶体聚团的理论出发,提出这些金属纳米材料的奇特性质可能与其在合成纳米结构单元时,形成了某种类晶格点阵有关。Fantastic characteristics and properties of metallic colloidal nano-materials have been introduced briefly. These distinguishing features and mystical natures include various respects of optimal, electronic or electrical, magnetic, mechanical, biological properties in physical chemistry as well as those in transport, etc. Furthermore, the current fundamental thory and practice about how to make nanomaterials with the advantages and disadvantages of different manufactures as well as how to explain the fantastic properties have also been described. Finally,a new point of view to explain the phenomena of nanometer materials the fantastic features of nanometer materials may be related to their cell units of nanometer structures while the metals-related particles mergering together based on a theory of colloid aggregation-has also been put forward,and verify the pint of view by some facts which we know at the present.
