Ionic Conductivity and Dielectric Properties of the PAN-Ion Conducting Polymers

1 Results In this work, the ion conducting films of polyacrylonitrile (PAN) containing lithium triflate (LiCF3SO3) and sodium triflate (NaCF3SO3) were prepared by the solution casting technique. The ionic conductivity measurements were carried out using impedance spectroscopy. The room temperature conductivity for pure polyacrylonitrile film is 1.51×10-11 S·cm-1. The room temperature conductivity for the highest conducting film in the PAN-LiCF3SO3 and PAN-NaCF3SO3 systems is 1.51×10-5 and 7.99×10-6 S·cm-1, respectively. The conductivity-temperature studies were performed in the temperature range between 303 and 373 K. The results for the variation of the conductivity with temperature obeys the VTF law. The increase and decrease in the number of ions can be implied from the plots of dielectric constant, εr-frequency and dielectric loss, εi-frequency.     

范德华力：生物学家、化学家、工程师和物理学家手册

利用双相光栅的激光束相干合成

本文介绍一种采用纯双相光栅进行激光束相干相加的方法。用一光栅能把单一光束高效率地分离成N个相等级次激光束,亦能以相同效率把N个相等级次的激光束转换成单一光束。实验证明,它能以75％的总转换效率将七束激光转换成一个单束激光。本文还描述一种实验装置,将两束氦-氖激光与三束氦-氖激光(波长为3.39μm)的功率合成,其效率可高达83％。     

A Study of Protein and Glycoprotein Syntheses in Pre-implantation Mouse Embryos Using Mini-2D-Electrophoresis, Video Densitometer Scanning and Computer-Image Analysis

In the present study, proteins and glycoproteins of mouse embryos at 2-cell,morula and blastocyst stages were analyzed.The techniques of ~(35)S-Met incorporation,ConA antiserum-precipitating ConA-binding proteins, mini-2D-electrophoresis, fluorography,video densitometer scanning and the computer-lmage system were used for analyses.Results of the investigations indicated that proteins and glycoproteins were synthesized by the embryos in a gradual increase manner from 2-cell to blastocyst. A relatively large amount of glycoproteins was synthesized during the morula and blastocyst stages.Two specific small glycoproteins respectively with molecular weights about 6500 and 9000 and PIs at 5.0 and 6.5 were apparently synthesized in the blastocyst but not in the 2-cell or the morula.

活动标形及其在点啮合齿轮传动误差分析中的应用

活动标形法的论述首推苏步青译，佐佐木重夫著《微分几何学》，还有的著作从外微分形式引入活动标形,本文论证取曲面的正交曲率网为参数网时，曲面论的基本公式就是活动标形的微分形式，并用其分析了点啮合齿轮传动误差．
