为判断CW-MFC反应器运行状态提供一种简单且快速的监测方法,利用三维荧光光谱法研究人工湿地-微生物燃料电池耦合系统(CW-MFC)启动过程中溶解性有机物(DOM)的光谱特征。结果显示CW-MFC反应器启动阶段的循环进水周期内类蛋白质峰荧光逐渐变弱,说明反应器内部微生物有较好的活性,而类腐殖质和类富里酸峰荧光呈现逐渐增强的趋势。同时,随着驯化时间的推移,在连续流进水周期内系统的输出电压基本维持在300 mV左右,COD、NH_(4)^(+)-N、TP的平均去除率也逐渐趋于稳定,分别为82.66%±4.47%、73.52%±6.95%和55.42%±8.59%。并通过比较反应器的出水中DOM组分荧光强度得分值,发现从启动到稳定运行的过程中反应器内部微生物的活性和代谢逐渐稳定,说明利用三维荧光光谱技术判断反应器是否运行稳定具有可行性。

水葫芦具有较高氢碳比,微波热解是其转化为清洁能源和高附加值化学品的有效方法。本文对水葫芦微波催化热解的特性进行较为系统的研究。实验结果表明:热解温度对生物油和热解气的总产率具有显著影响。随着温度的升高,生物油和热解气的产率增加,在600℃时达到最大。水葫芦的微波热解产物焦油中主要包含大量单环芳香族化合物和醇类化合物等,轻气体主要是氢气和一氧化碳。升温速率对水葫芦微波热解产物的产率和组分具有影响,随着升温速率的提高,半焦的产率增加,生物油的产率降低。较快的升温速率也有利于直链烃和一氧化碳的生成。

The WiFi fingerprint-based localization method is considered one of the most popular techniques for indoor localization. In INFOCOM'14, Li et al. proposed a WiFi fingerprint localization system based on Paillier encryption, which is claimed to protect both client C' s location privacy and service provider S's database ***, Yang et al. presented a practical data privacy attack in INFOCOM'18, which allows a polynomial time attacker to obtain S's database. We propose a novel WiFi fingerprint localization system based on CL(CastagnosLaguillaumie) encryption, which has a trustless setup and is efficient due to the excellent properties of CL *** prevent Yang et al.'s attack, the system requires that S selects only the locations from its database that can receive the nonzero signals from all the available APs in C ' s nonzero fingerprint in order to determine C 's location. Security analysis shows that our scheme is secure under Li et al.'s threat model. Furthermore, to enhance the security level of PriWFLCL, we propose a secure and efficient zero-knowledge proof protocol for the discrete logarithm relations in C 's encrypted localization queries.
