摘要：The presence of electromagnetic interference(EMI)leads to distortion of current and voltage waveforms,which reduces the accuracy and stability of sensor *** emergence of flexible electronic devices has broken the limits of physical space,as they can be bent and twisted at ***,this characteristic exacerbates unwanted coupling of their internal sensing elements,which can interfere with each *** present,the solution to EMI is based on electromagnetic shielding(EMS),but this method alone cannot solve internal EMI of flexible sensor *** this study,the gallium-based liquid metal(LM)circuits are printed on the Ecoflex@Fe film to realize a stretchable film with both EMS and wave-absorbing functions,which is expected to simultaneously address the effects of internal and external *** results show that the shielding efficiency of the electromagnetic wave shielding and absorbing(EWSA)film is as high as 54.5 dB on one side,while the reflection loss on the other side is as low as−43.5 *** addition,the LM-based EWSA film maintains positive wave-absorbing and EMS properties during stretching in different directions and it can also effectively avoid EMI after 1000 times of ***,the LM-based EWSA film,which enables broadband EMS and wave-absorption,provides a solution for the development of next-generation flexible electronic skin that eliminates both internal and external EMI.

摘要：针对视频帧间相对运动的目标检测,进行视频预处理,读取视频相关属性,运用二帧差分法、三帧差分法、彩色帧间差分法等,可以高效检测并处理视频运动目标,主要用大津法确定的图像二值化阀值,差分图像优化,使用腐蚀膨胀去噪点,再进行路径图初始化,画出圆心,根据时间的先后,找出存在圆心点,设计每帧停留时间,刻画出视频中出现运动轨迹,从而达到解决问题的目的。

摘要：对南宁市近30年来建成的住区建筑外遮阳进行调研,分析遮阳措施应用存在的问题,探讨夏季不同时段建筑遮阳的需求特点,最后立足于南宁市气候状况,提出居住建筑外遮阳设计的设计策略,为广西其他市区建筑外遮阳设计提供参考,以期推动广西地区建筑节能和绿色建筑事业的进一步发展。

摘要：本文基于南宁市建筑外窗热工环境存在的建筑外窗面积大,遮阳措施少;太阳辐射强度大,湿度高;可再生水资源利用率低;缺乏风环境规划等问题,分析建筑被动式喷雾蒸发降温技术及应用优势,即降温效率高、可增加空气湿度、可净化空气、基本配置较简单、运行费用低等,提出该技术应用特点,以期对相关行业的建设和发展提供借鉴。

摘要：夏季炎热干燥,熄火车辆在太阳直射下,坐垫和仪表盘等车内物品表温迅速升高,车内空间狭小、空气流通极差,加剧了高温产生的灼热感,使人感到极不舒适。为解决这一问题,开发设计了一种夏日车内自适应降温装置。该装置以温度检测模块、单向阀、触发模块、气囊、感应模块、气泵、封密块、透气管以及通风管等组成外辅助系统,分析车内温度,控制气泵与气囊工作,实现车辆在熄火与行驶时自动降低车内温度的目的,实现车辆自适应降温,减缓温度造成的不舒适感以保证乘坐体验与驾驶安全。

摘要：区块链应用于金融系统具有一定的可行性,但在实际应用中,仍出现一些安全性问题。文中介绍了当前区块链交易中遭受的攻击威胁,基于应对抗量子计算攻击、解决区块链热钱包私钥易被暴力破解的问题,提出了一种基于多变量公钥加密技术,并应用于区块链热钱包交易过程。通过构建私有链,分析对比多变量公钥密码加密后密文与SM2椭圆曲线数字加密后密文的结果、耗时,得出多变量公钥加密算法可以通过改变多变量公钥密码中G的仿射函数,增加公私钥、签名长度,证实了文中方案的可实现性。
