Research and Design of Network Management Construction Based on Mobile AGENT

The technical characters of mobile agent （MA） originated in the distributional artificial intelligence domain is introduced. A network management construction based on agent （NMCA） is then proposed. The NMCA structure features are elaborated in detail. A prototype design of NMCA is given by using the jKQML programming. The establishment of NMCA platform will be helpful to reduce the correspondence load of network management and improves the efficiency and the expansion ability of network management systems.     

A novel fuzzy clustering algorithm for the analysis of axillary lymph node tissue sections

Recently Fourier Transform Infrared (FTIR) spectroscopic imaging has been used as a tool to detect the changes in cellular composition that may reflect the onset of a disease. This approach has been investigated as a mean of monitoring the change of the biochemical composition of cells and providing a diagnostic tool for various human cancers and other diseases. The discrimination between different types of tissue based upon spectroscopic data is often achieved using various multivariate clustering techniques. However, the number of clusters is a common unknown feature for the clustering methods, such as hierarchical cluster analysis, k-means and fuzzy c-means. In this study, we apply a FCM based clustering algorithm to obtain the best number of clusters as given by the minimum validity index value. This often results in an excessive number of clusters being created due to the complexity of this biochemical system. A novel method to automatically merge clusters was developed to try to address this problem. Three lymph node tissue sections were examined to evaluate our new method. These results showed that this approach can merge the clusters which have similar biochemistry. Consequently, the overall algorithm automatically identifies clusters that accurately match the main tissue types that are independently determined by the clinician.     

香豆胶衍生物的化学结构及稳定性研究

将市售商品溶于水,用异丙醇沉析提纯,溶于0.1 mol/L NaNO3纯水溶液中,经0.5μm滤膜过滤后用水相凝胶渗透色谱法(GPC)测定,测得香豆胶(FG)、羟丙基香豆胶(HPFG)、阳离子香豆胶(CFG)的数均、重均相对分子质量Mn、Mw分别为:1.19×105、3.36×105,8.52×104、2.85×105,9.33×104、2.87×105。用甘露聚糖链在碱性条件下醚化时发生降解,解释两种改性FG的相对分子质量较FG低而多分散性(Mw/Mn)较FG高的测试结果。认为商品FG的1%水溶液黏度(1300 mPa.s)高于商品HPFG和CFG(分别为705和610 mPa.s)的原因是前者相对分子质量较高且残渣含量也较高(~10%,后二者为1%~2%)。HPFG的取代度为0.12,根据文献发表的13C-NMR数据确认HPFG分子链上羟丙基取代位置为C6。讨论了香豆胶(半乳甘露聚糖)的化学结构。热重分析法测定的热稳定性,HPFG高于CFG,CFG又高于FG。图6表3参13。     

东营凹陷岩性圈闭含油性定量预测

依据东营凹陷岩性油气藏勘探实践，其成藏主控因素概括为烃源岩、输导体系和成藏动力。以油气成藏动力为主线，从油气运聚的动力和阻力2个方面入手，将主控因素定量化，成藏动力为油气排出初始压力减去运移路径的压力衰减、储层静水压力和砂体毛细管压力。回归东营凹陷48个岩性圈闭的成藏动力与油气充满度的关系，建立了砂体含油性成藏动力定量预测公式。采用先确定烃源岩、输导体系和储层物性，最后计算成藏动力的方法，在对砂体钻预探井之前定量预测其含油性，从而降低勘探风险，提高勘探成功率。     

辐射剂量对环氧树脂电子束固化行为的影响

分析了电子束剂量对环氧树脂体系辐射固化行为的影响规律。研究结果表明，电子束辐射过程中，温度由树脂辐射体系表面向内部逐渐降低，随着辐射剂量提高，树脂体系温度上升，辐射表面与内部的温度梯度加大，高辐射剂量下的温度变化缓慢。树脂辐射固化层厚度以及在相同厚度的固化程度均随辐射剂量增加，但增幅逐渐变小，树脂辐射固化度沿固化深度会加速下降。
