Crystals of DL-threonium trichloroacetate (DLTTCA) was synthesized from an aqueous solution by slow evaporation technique. The grown crystals were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, UV-Vis-NIR and SHG measurements. Vibrational structure of the crystal was elucidated from FTIR analysis and the hydrogen bond interactions were discussed in detail. The ultraviolet transparent cutoff falls at 212 nm. Thermal stability of the compound was also studied. The powder SHG efficiency of the compound was measured as 0.62 times to that of KDP.

信息安全在企业信息系统建设中越来越重要,如何评价信息安全技术成为当前的一个研究课题.文中基于博弈论,对由防火墙、入侵检测系统和容忍入侵技术构成的三层安全体系结构进行了分析,提出了对信息安全技术进行评价的模型.在对入侵检测系统分析评价的基础上,重点分析了防火墙、入侵检测与容忍入侵的相互影响和关系.研究表明,IDS的检测率、误报率与防火墙的性能有密切关系,系统安全配置直接影响信息安全机制的性能和成本效益,容忍入侵机制取决于入侵的损失评估、系统的成本和防火墙与IDS的性能.信息安全机制的优化配置对于信息安全的效果具有重要影响.

讨论了Ni0·8Zn0·2Fe2O4(NZFO)与锆钛酸铅(PZT)的双层膜结构样品的磁电(ME)效应.NZFO粉料由溶胶-凝胶法制成,再经900℃热压,并高温烧结.在该双层膜中测量到了很强的磁电相互作用.发现横向的磁电效应比纵向效应大一个数量级,并且随NZFO烧结温度的提高而增加.当烧结温度从950℃上升到1380℃时,横向ME电压系数(αE)的最大值变化范围为25·6mV Am-2≤αE≤199·6mV Am-2.理论分析显示NZFO-PZT双层膜样品中ME效应源于NZFO与PZT之间相对良好的磁电耦合.
