What Is Its Real Existing Form?——Theoretical and Experimental Studies on 2-Mercaptobenzothiazole

1 INTRODUCTION The study of heterocyclic molecules with aroma- tic rings and their absorptions on metals is of con- siderable importance from both theoretical and te- chnological points of view. These molecules are in- teresting because of their applications as corrosion inhibitors and flotation collectors, and their abilities to form self-assembly layers[1]. 2-Mercaptobenzo- thiazole (C7H5NS2, in the following MBT) is an important heterocyclic molecule, which can be used as corrosion …     

超高压高精度激光状态方程实验测量

材料高压下的状态方程（EOS）在天体物理、材料科学和惯性约束聚变（ICF）等研究领域中都是十分重要的。2004年在“神光”-Ⅱ装置上进行了单路倍频激光直接驱动的Al-Cu阻抗匹配靶实验和Cu-Al阻抗反匹配实验，目的是提高冲击波速度的测量精度和准确性，同时校验测量方法的实用性和可靠性。

Recombination Efficiency in Double-Layer Organic Light-Emitting Devices

We analyse the influence of properties of organic/organic interface (OOI) on the characteristics of recombination efficiency of organic double-layer light-emitting diodes. Based on the disordered hopping theory model, spatial and energetic disorder of hopping states are also discussed for the case of space charge limited currents in hole transmitting layers but injection-limited currents in electron transporting layers. The results show that the recombination efficiency increases firstly and then decreases for different OOI parameters, and there is a maximum value changed with different spatial disorder parameters and energetic disorder scale. Different spatial disorder parameters make carrier mobilities change greatly, and the energetic disorder scale causes various localized state densities. Our calculated results are qualitatively in agreement with the experimental data.     

TiN和Ti1-xSixNy薄膜的微观结构分析

使用x射线衍射(XRD)、x射线光电子谱(XPS)、高分辨透射电子显微镜(HRTEM)和原子力显微镜(AFM)多种观测手段分析了TiN薄膜和Ti1-xSixNy纳米复合薄膜的微观结构.实验分析证明Ti1-xSixNy薄膜是由直径为3-5nm的纳米晶TiN和非晶Si3N4相构成,并且Ti1-xSixNy薄膜的表面粗糙度小于相同条件下制备的TiN薄膜,在Ti1-xSixNy薄膜体系的自由能中引入界面能的概念,在此基础上分析了体系中TiN晶粒的取向问题.     

爆炸驱动动能杆定向抛撒散布试验

动能反导技术作为新型的反导技术，原理是在拦截弹和目标的相对速度方向上，抛射出大量动能杆条毁伤目标。其核心技术之一就是动能元素的抛撒，特别是定向抛撒。国外研究一般集中针对既定抛撒装置结构的杆条抛撒结果验证性报道，缺乏对杆条抛撒影响因素的详细研究。本文提出了采用周向弧形状药选择区域爆炸驱动中心杆条束定向侧向飞散的动能扦定向抛撒装置方案，设计不同结构参数的杆条定向抛撒装置的试验，研究抛撒结构参数对动能杆的驱动特性影响规律，为新概念反导战斗部设计提供技术帮助。

Numerical investigation of confined swirling gas-solid two phase jet

This paper presents a k-e-kp multi-fluid model for simulating confined swirling gas-solid two phase jet comprised of particle-laden flow from a center tube and a swirling air stream entering the test section from the coaxial annular. A series of numerical simulations of the two-phase flow of 30μm, 45μm, 60μm diameter particles respectively yielded results fitting well with published experimental data.
