Abstract: 运用Boyd液膜扩散公式和范山鹰等提出的扩散模型,考察了碱性溶液中铜、锌氰配合物在离子交换纤维上的扩散行为;通过分析吸附前后纤维上官能团的位置变化以及解吸前后纤维上元素含量的变化,研究铜、锌氰配合物在纤维上的吸附机理。实验结果表明,离子交换纤维对铜、锌配合物的吸附在反应初期,以液膜扩散为主控制步骤,反应后期,以空隙扩散为主控制步骤。并运用离子交换纤维在水溶液中具有类似胶体型物质的双电层结构解释了不同控制阶段吸附速率不同的原因,虽然各阶段吸附速率有所不同,但纤维对铜、锌氰配合物的吸附均为离子交换机制。

Air-breathing scramjet propulsion is the basis of air-breathing solar thermal propulsion technology. How to design an ideal air-inlet is crucial for the propulsion system. By taking advantage of the common method, the DSMC(direct simulation Monte Carlo) on rare-field gas dynamics research, was made to simulate two kinds of air-inlets, which obtained a lot of air parameters such as temperature, density, coefficient of flow and velocity. Then it selected a better air-inlet shape from comparison and treated the shape as a basic air-inlet shape in air breathing solar thermal propulsion system. It lays a foundation for the design, computation, analysis and optimization on the whole system.

Abstract: Differences of cadmium uptake by plants of rice genotypes and relationships between the concentration of Fe deposited on root surface and the concentration of cadmium in plants were studied in agar culture under controlled conditions. The results showed that there were differences in cadmium taken up by root and shoot, cadmium accumulated on root surface of different rice genotypes, the transportation of cadmium from root to shoot in different rice genotypes, and the amount of iron oxides deposited on the root surface of different rice genotypes. There was a significant correlation between the concentration of Fe deposited on root surface and the Cd accumulated on root surface, root and shoot of rice.

Abstract: Backgrounds Recent explosion of biological data brings a great challenge for the traditional clustering algorithms. With increasing scale of data sets, much larger memory and longer runtime are required for the cluster identification problems. The affinity propagation algorithm outperforms many other classical clustering algorithms and is widely applied into the biological researches. However, the time and space complexity become a great bottleneck when handling the large-scale data sets. Moreover, the similarity matrix, whose constructing procedure takes long runtime, is required before running the affinity propagation algorithm, since the algorithm clusters data sets based on the similarities between data pairs. Methods Two types of parallel architectures are proposed in this paper to accelerate the similarity matrix constructing procedure and the affinity propagation algorithm. The memory-shared architecture is used to construct the similarity matrix, and the distributed system is taken for the affinity propagation algorithm, because of its large memory size and great computing capacity. An appropriate way of data partition and reduction is designed in our method, in order to minimize the global communication cost among processes. Result A speedup of 100 is gained with 128 cores. The runtime is reduced from serval hours to a few seconds, which indicates that parallel algorithm is capable of handling large-scale data sets effectively. The parallel affinity propagation also achieves a good performance when clustering large-scale gene data (microarray) and detecting families in large protein superfamilies.
Influence on Lubricant Properties of Anti-wear Agent Containing Nitrogen, Boron and Molybdenum
Xuguo Huai,Shihai Zhao
Modern Applied Science , 2009, DOI: 10.5539/mas.v3n6p136
Abstract: The lubricant property of composite lubrication oils was studied through the friction and wear experiment of the A3 steel-GCr15 steel pairs on the ring-block wear testing machine. The composite lubrication oils were prepared from base oil added various content (0, 2%, 3%, and 4%) of organic anti-wear agent, which contains Nitrogen, Boron and Molybdenum. In order to research the influence of the base oil, the non-brand base oil was selected to compare with the brand one. The results show that adding the anti-wear agent can enhance lubricant property and improve the frictional and wear resistance of materials. When the anti-wear agent content reached 3% in the composite lubrication, the A3 steel-GCr15 steel pairs possess the lowest friction coefficient and wear rate. The lubricant property of the non-brand base oil can be enhanced by adding anti-wear agent, even better than that of the brand with the same concentration (3%).
