wds

This paper introduced the research about the micro structure and the properties of the surface layer and the ferronickel core-copper clad boundary layer of dumet wire by means of AES 、 WDS and x-ray diffraction.

利用AES、WDS和x－射线衍射等方法，研究了杜美丝表面层、铁镍芯与覆铜层界面的微观结构与特性。

Station WDS mode enables packet forwarding at layer 2 level.

站波模式使包转发在第2层的水平.

The researches of this paper are as follows: 1. Research the market development and positioning of WDS, indicate the damage to telecommunication industry caused by user arrear.

研究无线数据业务的市场发展及定位，用户欠费对电信业的影响。

The NID and WDS were extrusive while the EDS 、 WPS 、 WSS and TB-EBS were fewer of PWSD.

56.74%,10.82%;其中以NID、WDS的 发生较突出,ODS、 WPS、WSS、TB-ECS相对较少.

The SEM , EDS, and WDS are used for the organic sulfur ( S _ o ) determination in coal.

应用扫描电镜 、 能谱仪和波谱仪测定了煤中有机 硫 含量.
