Path recovery aims at helping network operators automatically detecting and recovering from faults before human being’s intervening, and therefore can before customers notice these faults. By applying some algorithm of recovery, service provider (SP) can enhance the speed of repair and save paying refunds against broken service level agreement (SLA). Fast restoration of traffic after a network failure is a crucial aspect of current and future IP and transport networks. Recently, there is a… 相似文献

固定床煤气化炉中气氛对干馏层生成半焦的活性影响较大。对不同气氛下制得的半焦进行了CO2气化活性实验,并采用拉曼光谱和氮吸附对半焦进行了表征。结果表明:与N2气氛下制得的半焦相比,通入其他气体可以提高半焦的CO2气化活性,单组分中H2O气氛下制得的半焦的CO2气化活性最强,双组分中CO2+H2和CO+H2O气氛下制得的半焦的气化活性明显增加,而且双组分气氛下的CO2气化活性比前者强;半焦比表面积的增加有利于其CO2气化活性的提高,但半焦化学结构的变化对其CO2气化活性的提高作用更明显。 相似文献
