Domain name is the address of the computers , which is attached to the internet with the development of the internet , the function of domain name has become more and more important almost every company wants to have an extraordinary domain name used to symbolize itself in the internet and individual people wants to register a domain name with his name or the code which he likes 随着国际互联网的迅猛发展，网络在人们的生活中扮演着越来越重要的角色。人们可以足不出户在网上聊天购物、读书看报、旅游观光，可以两耳不闻窗外事而知晓家事、国事、天下事。网络使世界变小的同时，也为人们的精神生活提供了无限广垠的空间。
Alice noticed with some surprise that the pebbles were all turning into little cakes as they lay on the floor , and a bright idea came into her head . if i eat one of these cakes , she thought , it s sure to make some change in my size ; and as it can t possibly make me larger , it must make me smaller , i suppose 爱丽丝惊奇地注意到，那些小卵石掉到地板上部变成了小点心，她脑子里立即闪过了一个聪明的念头： “如果我吃上一块，也许会使我变小，现在我已经不可能更大了，那么，它一定会把我变小的。 ”
The refractive index and the changing behaviour of the a - sic : h films were calculated by using uv - vis - nir spectroscopy interference wave and it was found that the hydrogen content and ir transmittance were decreased with y rays irradiation dose . lt is very interesting that the sp ' c - h bonds were observed by the raman spectra for the first time and expand the application scopes of raman spectroscopy in structure analyse fields 根据uv ? vis ? nir光谱中的干涉条纹，计算出了y射线辐照下a - sic ： h薄膜的折射率及其变化趋势，并由此得出y射线辐照导致其氢含量变小及红外透过率变小的结论。有趣的是：还首次用raman光谱观察到了dlc薄膜中sp ~ 3c - h键随辐照剂量改变的变化规律，扩大了其在结构分析领域中的应用。
