引用

Chinese Journal of Aeronautics 2006年第B12期19卷 139-141页

作者： YANG rui-song CUI li-shan zheng Yan-jun Department of Materials Science and Engineering China University of Petroleum Beijing 102249 China

A new process of synthesizing TiNi/Ti2Ni composite particles, high temperature molten salts method, is introduced. This method uses molten salts as a reaction medium that does not take part in the chemical reaction and can be easily dissolved in rinsing water. According this method, the composite particles were prepared in molten salts at 700 ℃-900 ℃. By means of differential scanning calorimetry （DSC）, the reversible martensific transformation of TiNi particles in these composite particles was contemned.

Ammonia （NH3） detection at room temperature has attracted considerable attention because of the increasing demand for health monitoring, personal safety protection, and industrial manufacturing. Herein, we report the synthesis of polycrystalline SrGe409 nanotubes （NTs） via an electrospinning process. These NTs are a new sensing material for the detection of ammonia at room temperature. The SrGe409 NTs exhibited a maximum sensing response of 2.49 for 100 ppm NH3, which was increased to 7.08 by decorating the NTs with Pt nanoparticles. Flexible gas sensors were fabricated, which exhibited comparable performance to the rigid device. Additionally, the flexible devices showed excellent flexibility, mechanical stability, and sensing stability under different bending states, manifesting their potential applications in flexible and wearable electronics.

Evaluation of GNSS Signal-in-Space Continuity:A Weibull-Distribution-Based Method

引用

Chinese Journal of Electronics 2018年第3期27卷 634-640页

作者： li rui zheng Shuaiyong WANG Zhipeng TANG Yang SUN Si HUANG Zhigang School of Electronic and Information Engineering Beihang University Collaborative Innovation Center of Geospatial Technology

Signal-in-space(SIS) continuity is an important performance index of Global navigation satellite system(GNSS). However, the studies on the continuity of GNSS SIS are limited both at home and abroad, and are mainly based on the exponential distribution method. We first employ this method to analyze SIS failures of GPS and BDS, finding that this method is not flexile when describing the characteristic of GNSS SIS failures and the fitting characteristic of this method is not well. Therefore, we propose a method based on Weibull distribution to evaluate the performance of GNSS SIS continuity. Our method is compared with the models of exponential distribution, normal distribution, and Gamma distribution regarding the fitting characteristics of the interruption time interval of GPS SIS, the critical parameter of continuity. Results show that the fitting characteristic of the Weibull-distributionbased method is the best and can be used in various forms to describe reliability problem. Then our method is used to evalute the SIS continuity of BDS and GLONASS and its effectiveness and rationality are validated again. The contributions of our study lie in the development of a practical method for evaluating GNSS SIS continuity and a reference for GNSS performance.

In the research of windblown sand movement,the lift-off and incident velocities of saltating sand particles play a significant role in bridging the spatial and temporal scales from single sand particle＇s motion to windblown sand *** this paper,we achieved wind tunnel measurements of the movement of sand particles near sand bed through improving the wind tunnel experimental scheme of paticle image velocimetry（PIV） and data processing *** then the influence of observation height on the probability distributions of lift-off and incident velocities of sand particles was *** results demonstrate that the observation height has no obvious influence on the distribution pattern of the lift-off and incident velocities of sand particles,i.e.,the probability distribution of horizontal and vertical velocities of lift-off and incident sand particles follow a Gaussian distribution and a negative exponential distribution,***,it influences the center of the Gaussian distribution,the decay constant and the amplitude of the negative exponential distribution.

暴雨和洪涝对滨海城市的地下空间构成严重威胁,应急疏散效率在受灾场景中至关重要。研究表明空间分区能有效提高疏散效率。目前传统分区方法依赖单一的最短路径方法,无法兼顾安全与高效。该文基于安全性评估提出了一种精细化分区方法。首先以应急疏散为目的,对地下空间按功能划分;其次考虑到灾害风险性、人员聚集性和设施高效性三个维度的影响因素,并构建安全性分区评价体系;最后综合上述因素,构建精细化分区划定体系。文章以深圳红树湾地铁站为案例,验证了新方法在保障疏散安全的同时,提升了疏散效率,为地下交通枢纽的防灾规划提供了理论支持。
