为了促进钒渣镁化焙烧−酸浸提钒法的工业应用,研究钒渣镁化焙烧熟料中钒的酸浸出动力学。结合XRD、XPS和SEM,揭示在浸出初期的10 min内,MgSiO_(3)和大部分钒酸盐急剧地消耗酸,形成SiO2和V(V)的氧钒根离子。通过研究钒浸出效率随浸出时间的变化,建立钒浸出的动力学模型。结果表明,浸出过程分为两个不同的阶段,且两个阶段的动力学均遵循收缩核模型。0~10 min的浸出速率由固体产物层扩散和化学反应共同控制,而10~30 min的浸出速率仅由化学反应控制。因此,浸出初始10 min内加速传质很关键,而后续20 min内精确控温至关重要。

Query routing mismatch alleviation architecture for P2P file lookup in MANETs

引用

The Journal of China Universities of Posts and Telecommunications 2011年第4期18卷 111-117页

作者： MEI Jing-qing JI hong li yi Key Laboratory of Universal Wireless Communications Ministry of Education Beijing University of Posts and Telecommunications Beijing 100876 China

A cross-layer optimized query routing mismatch alleviation （QRMA） architecture is proposed to mitigate the problem of query routing mismatch （QRM） phenomenon between the structured peer to peer （P2P） overlay and the routing layer in mobile Ad-hoc networks （MANETs）, which is an important issue that results in the inefficiency of lookup process in the system. Explicated with the representative Chord protocol, the proposal exploits the information of topologic neighbors in the routing layer of MANETs to find if there is any optimized alternative next hop in P2P overlay during conventional lookup progress. Once an alternative next hop is detected, it will take the shortcut to accelerate the query procedure and therefore alleviate the QRM problem in scalable MANETs without any assistance of affiliation equipments such as GPS device. The probability of finding out such an alternative node is formulated and the factors that could increase the chance are discussed. The simulation results show that the proposed architecture can effectively alleviate the QRM problem and significantly improve the system performance compared with the conventional mechanism.

Multi-path routing based on load-balance for cognitive packet networks

引用

The Journal of China Universities of Posts and Telecommunications 2011年第5期18卷 71-75页

作者： CHEN liang JI hong li yi li Xi College of Information and Commumieation Engineering Beijing University of Posts and Telecommunications Beijing 100876 China

Quality of service （QoS） routing algorithms have been hardly discussed in the scientific community, most previous work on QoS routing concentrates on the performance of the single route. Cognitive packet network （CPN） has been designed for providing QoS routing. In this paper, to balance the loads among networks, we present a multi-path routing algorithm based on load-balance （MPRLB）, which is carried out in two steps. The algorithm with low computational complexity is firstly applied to establish multi path routing for each source and destination node pairs （SD-pair） nodes in the network. Then, we propose the hopfield neural network algorithm, which is applied to improve the efficiency of the flow deviation method for fast flow allocation among the links of the network based on load balance. Extensive simulation results demonstrate that the proposed scheme significantly improves the performance compared with the existing scheme that ignores load balancing.
