I/O switching off-loads much of I/O processing overhead from the server CPU and operating system to optimize switch-to-server I/O transfer .

i/o交换减少了服务器cpu和操作系统的很多i/o处理开销，优化了交换机到服务器的i/o传输。

The effects of different of categories surfactants, the proportion of surfactant and cosurfactant , the chain lengths of alcohol and alkane, temperatures and pH values on the W/O microemulsion phase areas are systematically studied in the dissertation. SEM and laser scatting techniques are used to verify particles'sizes of W/O microemulsion. Consequently, a system TritonX-100/n-C〓H〓OH (weight ratio 1: 1)/C〓H〓/H〓O is obtained which is a stable system with relatively large W/O microemulsion phase area.
