The third was to research how different lapping ways to affect the structures and properties of nonwovens and analyse the arrangement of fibers by calculating the value of MD/CD and the lapping angle.

Discussion on integration networking mode of PSTN and NGN;

This paper introduces the networking mode of WAC, and taking the WAC business of Shanxi Administration Bureau of the Prison as an example, expounds the distribution of WAC system data and some items needing attention in the maintenance.

The networking mode, synchronization, structure, construction principle and allocation of technical specification of digital synchronization network and the requirements of the synchronization equipments on the clock are briefly discussed.

Discussion of 500kV digital substation network mode and VLAN partition

It is necessary to analyze the characteristic and function of tactical data link network mode,and furthermore,the description of tactical data link operational capabilities is concentrated on cycle-time and surveillance capacity.

The digital substation construction scheme,engineering application model,network mode and the configuration of relay are discussed.

To meet the require-ments of IEC 61850 for functional hierarchy,three types of CNDS network structures are proposed based on its clarified functional targets:point-to-point / multi points at process level,bus at process level and internal unique network.

According to the characteristics of visual building conversational system the function design,video networking ways and distribution system of this system are introduced.
