Emotional agent based on rough set

To improve the ability of agent for handling emotions, a new architecture for emotion agent is presented, based on the traditional BDI agent model and the rough set theory. By a new emotional reasoning algorithm based on rough set, the architecture performs emotion reasoning and implements the emotion treatment. An emotional agent grid based on this architecture has been realized, experiment results show that it is efficient to transact simple emotions by emotional agents.

Effects of Ti on N distribution and diffusion in FeTiN thin films

We studied the distribution and diffusion of N atoms in FeTiN single-layer and bilayer thin films by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). We found that in as-deposited films N atoms are first absorbed by Ti atoms, the rest being dissolved into FeTi lattices. Ti not only directly absorbs N by chemical bonding, but also decreases the energy of the N atoms that are dissolved into FeTi lattices. The diffusion study of N atoms in single layer and bilayer films showed that although the presence of Ti stabilized the /spl alpha/ phase of FeTi lattices during 200/spl deg/C annealing, the diffusion length of dissolved N in FeTi (Ti/spl les/8 at.%) lattices was still comparable to the diffusion length of N in pure Fe. Thus, the addition of a small amount of Ti in /spl alpha/-Fe lattice can not completely stabilize N atoms in the film, and the induced magnetic anisotropy of the films can still be unstable, although the /spl alpha/ phase of FeTiN is stabilized by the addition of Ti. The distribution of N atoms in bilayer films can be fitted by a simple enthalpy model.     

巴基斯坦独立以来与中国关系的变迁及启示

巴基斯坦作为当代与中国关系较为亲密稳固的国家之一,同时亦有着"宗教国家"与"美国旧盟友"的双重身份。从两极格局时的紧张对立到新世纪的紧密合作,中巴关系在国家利益与友谊的牵引下不断摸索着、发展着、巩固着。巴基斯坦作为宗教大国,对我们而言探究中巴关系变迁可以为当代中国进一步拓展与伊斯兰国家的关系找到突破口,加快与这些国家交往的步伐;同时,它对提高中国在伊斯兰国家的影响力也是有重大意义的,具有研究价值。

磺化聚苯乙烯/聚乙烯醇交联膜的制备与性能

以磺化度为75%的磺化聚苯乙烯(SPS)和聚乙烯醇(PVA)为原料,按一定的配比共混后浇铸成膜,在程序升温的过程中进行热交联,通过控制不同交联时间得到不同交联密度的交联膜.考察了交联膜的离子交换容量(IEC)、吸水率、溶胀性和尺寸稳定性;利用原子力显微镜和交流阻抗仪对交联膜的表面形貌及电导率进行了表征.结果表明:交联膜的IEC值略有降低;吸水率和溶胀度得到了很好的控制,具有较好的尺寸稳定性;膜表面出现了明显的亲水相和憎水相相分离,且亲水相微区的聚集尺寸和连续性随交联时间的长短而变化;随交联时间的延长,交联膜的电导率值略有下降,但交联后膜的室温电导率仍高于0.01 S/cm.

无限长圆柱体的热弹性耦合问题

应用经典传热学理论,研究无限长圆柱体的热弹耦合问题。建立了经典传热学理论的控制方程,借助拉普拉斯积分变换及其数值反变换技术对问题进行了求解,得到了瞬态热冲击作用下无限长圆柱体中的温度、应力、位移的分布规律。从其分布图上可以看出,介质中呈现出热弹耦合效应。并且比较了传统热弹性理论与广义热弹性理论。
