Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.
纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征,如原来是良导体的金属,当尺寸减小到纳米量级时就变成非金属型;原来是绝缘体的物质,当尺寸减小到几纳米或几十纳米时电阻大大下降,失去了绝缘体特性;常规固体在一定条件下物理性能是稳定的,在纳米状态下,颗粒尺寸对性能产生强烈的影响等等,这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景,因此,纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议,正式把纳米材料科学作为材料科学的一个新的分支公布于世。

This phenomenon which is similar to liquid is validated under normal temperature and pressure on the surface of pure metal, alloy, mylonitic quartzite, gabbros et al. using metallographic microscope, TEM, SEM, AFM and X-ray diffractometer based on preceding researchers. The phenomenon reveals a new matter existence state in non-extreme arduous conditions, besides the well-known states, gas, liquid, solid and liquid crystal.
本文在前人研究的基础上,采用金相显微镜、透射及环境扫描电子显微镜、原子力显微镜和X 射线衍射仪等观测仪器,对纯金属、合金和非金属材料糜棱状石英岩、辉长岩等进行观察,验证了在常温常压下,这些材料中存在着一种未被人们认知的,具有类似流体特征的非线性振荡现象——&类流态&现象,是一种非极端条件下新的物质存在状态。
