SHTML和HTML的区别,如果用一句话来解释就是:SHTML 不是HTML,而是一种服务器 API,shtml是服务器动态产成的html.
利用SHTML格式的页面目的和 ASP 差不多,但是因为是 API 所以运转速度更快,效率更高,比ASP快,比HTML慢,但由于可以使用服务器端包含,因此使页面更新容易（特别是批量更新banner,版权等. 2.
STM:scanning tunneling microscope 即扫描隧道显微镜.
The scanning tunneling microscope (STM) is widely used in both industrial and fundamental research to obtain atomic-scale images of metal surfaces.It provides a three-dimensional profile of the surface which is very useful for characterizing surface roughness,observing surface defects,and determining the size and conformation of molecules and aggregates on the surface.Several other recently developed scanning microscopies also use the scanning technology developed for the STM.A precursor instrument,the topografiner,was invented by Russell Young and colleagues between 1965 and 1971 at the National Bureau of Standards (NBS) [currently the National Institute of Standards and Technology (NIST)].
3.STM:Synchronous Transfer Module 同步传输模块
4.SDH的基本速率是155.52Mb/s 称为第1级同步传输模块,即STM-1,相当于SONET体系中OC-3的速率.
