Entropy of Partitions on Quantum Logic

Partition and entropy of partitions in quantum logic are introduced and their properties are investigated. The results are generalized to the general case of T-norm and T-conorm.     

Tb(Ⅲ)-EDTP-吡啶-2-甲酸三元体系的溶液荧光

Ｔｂ－乙二胺四亚甲基磷酸－吡啶－２－甲酸三元体系的溶液荧光呈典型的Ｔｂ（Ⅲ）离子的特征荧光,而激发峰位于３１０ｎｍ,为吡啶－２－甲酸的吸光区域,表明在溶液中形成了Ｔｂ－乙二胺四亚甲基膦酸－吡啶－２－甲酸三元配合物。该三元配合物的荧光在ｐＨ为６．０时最强,同时随吡啶－２－甲酸含量的增加而增加,但过量的乙二胺四亚甲基膦酸的加入不影响体系的荧光。     

医用CVIC/C复合材料表面仿生沉积生物活性钙磷涂层

为了在医用化学气相渗透工艺(CVI)C/C复合材料表面制备生物活性钙磷涂层,用阴极声电化学工艺处理CVIC/C复合材料,再将试样浸泡于过饱和钙磷溶液中,使其诱导钙磷晶体生长.XPS研究表明,经声电工艺处理后,CVIC/C复合材料表面发生了改性;SEM,XRD和FTIR研究表明,在过饱和钙磷溶液中,未经声电化学处理的CVIC/C复合材料不具有诱导钙磷晶体生长的功能,而改性的CVIC/C表面能够诱导钙磷晶体生长,形成片状五水磷酸八钙(OCP)涂层.同时讨论了OCP沉积的形成机理.

Electromagnetic reflection and transmission from a new version of Cantor fractal nonlinear multilayers

In this paper, we put forward a new version of Cantor fractal multilayers, which are nonlinear medium, and investigate its properties of reflection and transmission when a plane wave is obliquely incident upon it. A new exact self-similarity algorithm that make use of the self -similarity of these structure are developed. The results for different stages of fractal growth within the first-order nonlinear approximation are found. Compared with the traditional chain-matrix approach, the scheme provides the reflection and transmission coefficients for any stage (S) with much less calculation time on a personal computer.     

用于高性能锂-硫电池的氮化硼纳米片/碳纤维改性隔膜

通过静电纺丝、热亚胺化和碳化过程,将氮化硼纳米片(BNNSs)负载在碳纤维(CFs)表面,组成用于修饰商业聚丙烯(PP)隔膜的氮化硼纳米片/碳复合纤维(BNNSs/CFs)复合材料。BNNSs和CFs的协同作用为电池提供了额外的导电路径,并将可溶性多硫化锂固定在正极区域。结果表明,采用10BNNSs/CFs-PP隔膜的电池在0.05C下的初始放电容量高达1 295.7 mAh·g^-1,当电流密度增加到1C时,以10BNNSs/CFs-PP为隔膜的电池也具有良好的长期循环稳定性,在400次循环后最终容量高达583.1mAh·g^-1,每次循环容量衰减0.069%。
