Tests prove that the average data transfer rate of the RAID which uses the read prefetch policy increases! by 60%, meeting the high requirement of I/ O performance in digital systems. 实验表明,采用顺序读预取策略的实际读平均数传率提高了60%,可以满足数字化系统对I/O性能的高要求。
Also as the angle decreases, the maximum pressure coefficient on the impingement surface decreases, the maximum local Nusselt number remains nearly constant, and the average heat transfer rate along the impingement surface decreases. 当倾角减小时,冲击表面压力系数最大值降低,局部Nu最大值没有明显的变化,射流与冲击面之间的平均传热率降低。
This article improves on fair scheduling algorithm based on statistics. It retentions the maximum signal-to-noise ratio and the virtual time, and then adds users with an average data transfer rate. 本文在统计公平调度算法的基础上进行改进,保留最大相对信噪比与虚拟时间的因素,再加入用户的平均数据传输速率,三者相结合共同决定算法的调度结果。
When the porosity becomes smaller, the average heat transfer coefficient change rate increases. 而随着孔隙率的减小,平均换热系数随空气流量变化的变化趋势增大。
