Journal of Iron and Steel Research International 2005年第3期12卷 56-59页

作者： HANJian-min LIUYuan-fu LIWei-jing LIRong-hua XUXiang-yang WANGJin-hua BeijingJiaotongUniversity Beijing100044China

A new type of Nb-V-Ti microalloyed cast steel was produced. Computer simulation was adopted to optimize the content of alloying elements. The microstructure of the microalloyed steel was analyzed. The fatigue property, wear and friction properties and rupture toughness of the steel were investigated. The service and operating properties of Nb-V-Ti microalloyed cast steel coupler were also examined. The results show that the steel has excellent comprehensive mechanical properties. The granular bainite structure and precipitation strengthening are the primary strengthening mechanism. The fine grain brings the steel good plasticity and excellent toughness. Various service and operating properties of Nb-V-Ti microalloyed cast steel automatic coupler are excellent.

采用概率反演分析法估算黄土高原草地和农田生态系统各碳库滞留时间及固碳潜力。结果表明:除农田植物地上部分外,植物地上部分、地下部分、代谢性凋落物及土壤活性有机碳库滞留时间最短,为25~203d;惰性凋落物碳库滞留时间为2.4~3a;慢性有机碳库和惰性有机碳库滞留时间最长,分别为57.4~79.6a和593~598a。多年生草地的根系滞留时间显著高于农田;而农田代谢性凋落物碳库和慢性有机碳库的滞留时间显著高于草地。根据反演所得参数模拟,在当前气候和土壤条件下,农田和草地系统土壤有机碳在250a左右时达稳定状态,农田系统固碳潜力约为2 680g C·m^(-2),草地约为3 130g C·m^(-2)。农田有机肥的输入能使土壤有机碳多固定4 000g C·m^(-2)。有机肥的输入及土壤有机碳周转缓慢使耕作农田比草地更有利于土壤有机碳积累。
