液晶基元直接横挂于主链上的液晶共聚物的合成与研究

以含液晶基元的单体２，５－双（４－甲氧基苯甲酰氧基）苯乙与苯乙烯通过自由基共聚合反应，首次合成了一系列含液晶性和非液晶性两种序列结构的共聚物。采用ＤＳＣ、偏光显微镜和Ｘ衍射方法研究了共聚物的液晶行为，发现单体和共聚物（只有ＣＰ－５和ＣＰ－６）有很好的热致液晶性。随共聚物中介晶单体单元含量的增加，共聚物玻璃化转变温度Ｔ和热分解温度Ｔ呈规律变化。

On collaborative content distribution using multi-message gossip

We study epidemic schemes in the context of collaborative data delivery. In this context, multiple chunks of data reside at different nodes, and the challenge is to simultaneously deliver all chunks to all nodes.     

A Mass Transport Model for Drying Wood under Isothermal Conditions

Mass transport in wood during drying can have different mechanisms at different periods of drying. Depending on the current moisture content (MC) and the structure of the wood, the driving forces for the mass transport are essentially different. Above the fiber saturation point (FSP), the lumens are partially saturated and the transport of liquid (free) water occurs as a consequence of capillary action. On the other hand, below the FSP, bound water within the cell walls is conveyed by diffusion, and water vapor in the lumens moves under influence of pressures gradient. Based on these considerations, a unified model is presented that takes into account the transport of the different moisture phases. Simulation of the drying of a Norway spruce sample at 50°C from about 135 to 7% MC is carried out using the finite element method (FEM). Comparison between the simulated average MC and the experimental observations obtained from X-ray computed tomography (CT) shows reasonable agreement. Possible simplifications in the model are briefly discussed as well as some aspects of the numerical implementation. Finally, the influence of absolute permeability on the average MC is studied.     

戊二醛含量测定方法的改进

对戊二醛测定方法进行改进 ,采用酸度计判定终点的方法代替用肉眼观察指示剂变色来判定终点。改进后的方法平均偏差为 0 .0 4,标准偏差为 0 .0 2。并且在正常情况下 (试样无色 ,含量≥ 1% ) ,改进前后的测试方法的数据结果基本一致。而当试样含量≤ 1%或试样有色时 ,则测试结果相差很大。
