摘要：文章探讨量化中医气虚的方法,采用无创NIrS技术检测SaO_2,实现对气虚的量化评价。常规SaO_2检测无法实现对气虚的辨识,采用为实验专门设计的屏息测试法可以实现对气虚的量化评估。初步实验结论表明诸如Sa O2min(%)、CIO_2(m L/min)可以在实时检测的血氧饱和度曲线中得出。该屏息测试法会使得被测者产生较强烈的窒息感,应用层面上的普遍推广会有困难。替代方案是采用多信息同步分析策略,文章阐述了ECG、PPG等信号的合参方法,同步检测方法可以更好地量化气虚的程度,在临床应用中实现精确的诊断评估与疗效评价。

摘要：To develop a high performance buckling-restrained brace （BrB） with less weight, an innovative type of the BrB with transverse rib restraints is proposed and studied through experiment. Three BrB specimens are cyclically loaded in the investigation. Specimen 1 adopts a Q235 core member and transverse rib restraints. Specimen 2 adopts a LYP160 low yield point steel core member and transverse rib restraints. Specimen 3 adopts a LYP160 low yield point steel core member and mortar restraint. The experimental results indicate that the transverse rib restraining mode can provide sufficient lateral stiffness for the core member and effectively restrain its buckling. The BrB specimens with a LYP160 core member exhibit better hysteretic performance and energy dissipation capacity than the specimens with a Q235 core member.

摘要：In order to effectively detect malicious phishing behaviors, a phishing detection method based on the uniform resource locator （UrL） features is proposed. First, the method compares the phishing UrLs with legal ones to extract the features of phishing UrLs. Then a machine learning algorithm is applied to obtain the UrL classification model from the sample data set training. In order to adapt to the change of a phishing UrL, the classification model should be constantly updated according to the new samples. So, an incremental learning algorithm based on the feedback of the original sample data set is designed. The experiments verify that the combination of the UrL features extracted in this paper and the support vector machine （SVM） classification algorithm can achieve a high phishing detection accuracy, and the incremental learning algorithm is also effective.

摘要：为降低叶顶泄漏损失,本文首次将NACA翼型引入向心涡轮,并采用正交试验设计和计算流体动力学(CFd)方法获得了具有最优NACA叶顶型线的向心涡轮叶片,并揭示了该叶片对叶顶泄漏损失的控制机理。结果表明,最优NACA叶顶型线具有较大的前缘内接圆半径、较小的尾缘厚度,以及更靠近前缘的最大厚度位置。其内接圆半径和最大厚度位置对向心涡轮等熵效率的影响度也随叶顶间隙增加而增大。当叶顶间隙为8%出口叶高时,最优NACA叶顶型线可使向心涡轮等熵效率提高1.47%,并使向心涡轮能够在非设计工况下具有较高效率。该型线能够降低尾缘附近的叶顶泄漏速度,减弱泄漏流与主流掺混强度,使流动损失降低。

摘要：Tandem electrocatalysis is an emerging concept for effective electrochemical CO_(2) reduction reaction(CO_(2)rr)towards multicarbons(C_(2+)).This decouples the multiple steps of CO_(2)-to-C_(2+)into two steps of CO_(2)-to-CO and CO-to-C_(2+)catalyzed by individual catalysts,to improve the Faradic efficiency(FE).However,due to the mass-transport limitation of CO from the generation site to the long-distance consumption site,such a strategy still remains challenge for high-rate production of C_(2+)***,we designed CuO/Ni single atoms tandem catalyst,which made the catalytic sites of Ni and Cu for independently catalyzing CO_(2)-to-CO and CO-to-C_(2+)compactly neighbored,enabling the in-situ generation and rapid consumption of *** CuO/Ni SAs tandem catalyst achieved a particularly high partial current density of C_(2+)products(1220.8 mA/cm^(2)),while still maintained outstanding C_(2+)products FE(81.4%)and excellent selectivities towards ethylene(FE 54.1%)and ethanol(FE 28.8%),enabling the profitable production of multicarbons by CO_(2)rr.
