建立地图制印质量评价模型。
This article first introduces IETF GMPLS-based peer madel and ITU-T ASON-based overlay model together with their comparison.
首先介绍了IETF的基于GMPLS对等模型和ITU T的ASON重叠模型，并且比较了它们之间的关系；
The simulation program for the valve motion was developed, and simulation tests were carried out on the valves of both Model F800 and Madel 3nb-1300 drill pumps.
此外编制了泵阀运动规律的仿真程序，并分别对F800钻井泵泵阀和3nb—1300钻井泵泵阀进行了仿真试验。
