本建议涉及G.803。描述的分层和分块的传输网的管理要求。
8.Results There were not significant difference between FMD and change of blood flow volume of reactive hyperaemia in SDH and control group.
结果SDH组与对照组相比FMD和与反应性充血后肱动脉血流量的变化未见明显差异，无统计学显著性差异。
9.The system is independent of actual SDH equipments because we construct a abstract model for the equipments.
本系统对SDH设备进行了抽象，使得系统实现与具体的设备无关；
10.The results indicate that experimental group and control group's SDH activity has an obvious difference.
