By the systematic ‘study upon the technical key points to produce 150dtex/48f multi-interlacing PET fila-ments, it was found that in order to obtain the higher degree of intertwining.

Impact of Social Network Density on Innovation Diffusion

The relationships between the vinyl content and the properties as well as the network density of solution polymerized SBR (S-SBR) were studied.

Based on the fact that the performance of distributed real-time control systems closedthrough control network depends on not only control algorithms but also network scheduling, timedivision multiple access (TDMA) with determinate timing and reliability was used as control network todescribe the control messages through network.

Based on control performance optimization and network scheduling condition, considering system control and network scheduling, an optimized model and sampling period selection algorithm were proposed.

From the point of view of network, architecture and protocol, time\|delay analysis and network scheduling, transmission of data packets, communication constrains and integral of systems and information in the networked control systems are discussed.

For unifying the standard of judgement of network speed between users and network manager, the article introduces a method and implement the system to indicate network speed by measuring the accessing speed to website.

At present,network speed is a serious bottleneck problem for multimedia instruction in network environment.
