2·4-二羟基苯甲醛缩氨基硫脲合锌(Ⅱ)镍(Ⅱ)的合成与表征

近50年来,人们对含5、N席夫碱在抗癌抗病毒和抗菌活性方面的研究十分活跃,发现α—异喹啉甲醛或α—吡啶甲醛缩氨基硫脲等具有明显的抗癌抗病毒活性,而当它们与金属离子配位后,活性明显增强。为了寻求高效低毒的抗癌抗病毒抗菌剂,我们合成了末见文献报导的2,4—二羟基苯甲醛缩氨基硫脲合Zn(Ⅱ)、Ni(Ⅱ)两种化合物,并对其进行了表征。     

灰色模型在疲劳寿命预测中的应用

疲劳寿命预测的问题是疲劳研究中的重要课题。影响疲劳寿命的因素多且复杂,利用灰色理论方法进行疲劳寿命预测,提出了非等间距GM(1,1)模型和中心逼近式GM(1,1)模型两种预测疲劳寿命的方法。通过对实验数据进行分析和整理,然后建立微分方程,利用MATLAB软件计算得到灰色预测值。与实验数据值进行比较,得出结果表明灰色模型方法具有很高的预测精度,证明灰色理论是一种简单可行的、可靠的分析方法。

Simulation Might Change Your Results: A Comparison of Context-Aware System Input Validation in Simulated and Physical Environments

Context-aware systems(a.k.a.CASs)integrate cyber and physical space to provide adaptive functionalities in response to changes in context.Building context-aware systems is challenging due to the uncertain running environment.Therefore,many input validation approaches have been proposed to protect context-aware systems from uncertainty and keep them executing safely.However,in contrast to context-aware systems'prevailing in physical environments,most of those academic solutions(83%)are purely evaluated in simulated environments.In this article,we study whether this evaluation setting could lead to biased conclusions.We build a testing platform,RM-Testing,based on DJI RoboMaster robot car,to conduct the physical-environment based experiments.We select three up-to-date input validation approaches,and compare their performance in the simulated environment and in the physical environment.The experimental results show that all three approaches'performance in simulated environments(improving task success rate by 82%compared with the system without the support of input validation)does differ from their performance in a physical environment(improving the task success rate by 50%).We also recognize three factors(scenario setting,physical platform and environmental model)that affect the performance of input validation approaches,based on an execution model of the context-aware system.

基于CFD的微流体滤波器数值模拟及优化研究

随着微机电系统的不断发展,微流体控制系统已成为目前乃至今后研究的重点问题。微通道内流体流动稳定性对系统结果分析有较大影响,消除流体脉动分量,研究影响流动稳定性的各因素至关重要。基于数值方法,计算了微流体滤波器周期性流动过程,分析了周期平均速度、脉动速度振幅、脉动频率对滤波效率的影响。研究表明:微流体滤波器第一级滤波腔的滤波效率受周期平均速度影响较大;周期平均速度相对越大,滤波效率越低;而第二、第三级滤波腔的滤波效率受周期平均速度、脉动速度振幅、脉动频率的影响均较小,可忽略不计。
