氮化物添加对钛酸钡半导瓷电阻—温度曲线之影响

本文研究了氮化物添加对钛酸钡半导瓷电阻－温度曲线之影响，实验表明，除ＮＢ外ＴｉＮ、Ｓｉ３Ｎ４、ＡｌＮ也可以给出较平坦的电阻极大值，在适当的工艺条件下没有氮化物添加同样可以得到类似结果。     

立磨底座制做的改进

立磨是一种用途很广的烘干兼粉磨设备,基于其工作原理、研磨机理、机械结构、系统工艺性能等方面的优点及特点,越来越得到水泥行业的重视,随着窑外分解技术的发展,各国水泥行业越来越多地采用立磨粉磨水泥原料与熟料.目前国内引进了大量国外立磨,如宇部立磨、德国莱歇立磨等等,并参与数台立磨国内分交件的加工制做.在立磨整体结构中底座是非常重要的一件,其主要作用是支撑整个磨机的重力和承受动力,因此底座的制做质量直接影响着整个磨机系统的正常运转.本文主要论述的是日本宇部立磨的底座在制做方面的改进（为便于运输且不影响使用）.其大体结构如图1所示（原图）：

Mode III fracture of a magnetoelectroelastic layer: exact solution and discussion of the crack face electromagnetic boundary conditions

This paper develops a closed-form solution for anti-plane mechanical and in plane electric and magnetic fields in a magnetoelectroelastic layer of finite thickness. Explicit expressions for the stresses, electric fields, and magnetic fields, together with their intensity factors are obtained for the extreme cases for impermeable and permeable cracks. Solutions for some special cases, such as a magnetoelectroelastic layer with infinite thickness, are also obtained. Applicability of the crack face electromagnetic boundary conditions is discussed. It is found that the crack profile is important in obtaining the correct electromagnetic fields and their intensity factors. The stress intensity factor, however, does not depend on the crack face electromagnetic boundary condition assumptions.     

Reproducibility and stability of N–Al codoped p-type ZnO thin films

Reproducible and stable p-type ZnO thin films have been prepared by the N–Al codoping method. Secondary ion mass spectroscopy measurements demonstrate that N and Al are incorporated into ZnO. The resistivity, carrier concentration, and Hall mobility are typically of 50–100 Ωcm, 1×10¹⁷–8×10¹⁷ cm⁻³, and 0.1–0.6 cm²/Vs, respectively, for the N–Al codoped p-type ZnO films. Hall measurement, X-ray diffraction, and optical transmission were carried out to investigate the changes of the properties with the storage period. Results show that the p-type characteristics of the N–Al codoped ZnO films are of acceptable reproducibility and stability. In addition, the N–Al codoped p-type ZnO films have good crystallinity and optical quality. The properties are time independent.     

Fabrication and characterization of Zr and Co co-doped LiMn2O4 nanowires using sol–gel–AAO template process

The Zr and Co co-doped LiMn₂O₄ nanowires are fabricated successfully by using sol–gel process with porous anodic aluminum oxide (AAO) as the template. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) characterization show that the synthesized LiZr _x Co _y Mn_(2-x-y)O₄ nanowires are uniformly distributed, high-ordered, and parallel to each other, and few microscopic defects are found. Selected area electron diffraction (SAED) pattern, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) investigations jointly demonstrate that the synthesized nanowires have a similar single spinel structure of LiMn₂O₄ crystal though Zr and Co are doped. Since the LiZr _x Co _y Mn_(2-x-y)O₄ nanowires can be mass-produced by using this method, it is expected to find promising application as a new cathode material in lithium ion battery.
