纳米丝、纳米线、纳米棒是实心的准一维纳米材料,长度比直径通常要大得多,可以是宏观量级。纳米丝、纳米线、纳米棒三者之间的区分并不严格,通常将长径比(长度与直径的比值)较大的称为纳米丝,长径比较小的称为纳米棒。

这是 William E. Buhro 的观点

The prefix "nano" implies that the diameter of the 1D structure is
in the nanometer regime, rather than larger than a micrometer. The term "fiber" implies nothing specific
about the structure of the fiber - it may be a single crystal, crystallographically amorphous (like
conventional glass is), polycrystalline, etc. The term "whisker" is generally accepted to mean that the 1D
structure is a single crystal, or at least approaches single-crystal character fairly closely. "Tube" of course
implies a hollow center. "Nanowire" is perhaps the most troublesome. To some of us the term "nanowire"
implies that the electrical-transport measurements have been made, and the 1D structures have been
found to be either semiconductors or metallic conductors. To others, the term "nanowire" is used in much
the same way as "nanofiber." So you can see, standard definitions have not yet been fully developed.
Nanotubes may also be considered to be "nanowires." Nanowires must not necessarily be fully dense as
our's are; they could be hollow

用宏观的东西来理解就成,不就是加了个nano-么!

顶高手,会用换位思考法。哈哈。。。

这个我现在还真没发现~~~

看看比较权威的文献,你就明白了,首先纳米带就是他提出来的——王中林

感觉一样
不过应该要有个标准吧~
