查询词典 distribution system

This paper presents a self-adaptive load balancing algorithm, in which each peer creates a local load distribution view using a passive load statistic method and a local file requested view using file requested statistic method. When load imbalance exists in the system, the heavy loaded peer will make the logical links which point to itself to point to a light loaded peer in its local load distribution view, with the indegree of the heavy loaded peer decreasing and the indegree of the light loaded peer increasing, the load imbalance magnitude will decrease. When the request load of the heavy loaded peer is high, the peer will use its local file request view to get the popular file and cache the file to corresponding target peer.

提出一种自适应负载均衡方法，方法采用一种被动式结点负载统计方法生成局部负载视图；采用一种文件访问统计方法生成局部文件访问视图；当系统内结点负载存在差异，重载结点把指向自身的逻辑链路迁移至指向局部负载视图中的轻载结点，通过减小重载结点入度和增加轻载结点入度来减小结点间负载差异；当结点的请求负载较高时，通过局部文件访问视图计算需要缓存的热点文件及目标结点，降低承载热点文件的结点的请求负载。

Numerical simulation results show that the fluid flow in Lost Foam Process was different from that in an ordinary green sand mold, the molten metal flow forwards in a circular-arc shape from the ingate, meanwhile, the nature of the gating system influenced the filling process notably. As the polystyrene pattern decomposition has a strong quenching effect on the flowing metal fornt, a high temperature gradient was formed at the flowing metal front, this resulted in the dropping of temperature of the metal to the liquidus temperature quickly and decreased the flowability of molten metal, the temperature distribution in the metal behind, however, was even. The properties of the pattern and the coating affected the temperature distribution remarkably.

从内浇口开始，金属液呈放射状均匀向前充填，同时浇注系统性质显著影响金属液充型过程的流场；由于聚苯乙烯模样气化吸热对金属液的激冷作用，在金属液流端部区域产生很大的温度梯度，使得端部区域金属液很快降至液相线温度，降低了金属液的充型能力，而后续金属液中温度分布则比较均匀，模样性能、涂料性能显著影响这一温度分布特点。
