The rapid detection of microparticles exhibits a broad range of applications in the field of science and technology. The proposed method differentiates and identifies the 2 μm and 5 μm sized particles using a laser light scattering. The detection method is based on measuring forward light scattering from the particles and then classifying the acquired data using support vector machines. The device is composed of a microfluidic chip linked with photosensors and a laser device using optical fiber. Connecting the photosensors and laser device using optical fibers makes the device more diminutive in size and portable. The prepared sample containing microspheres was passed through the channel, and the surrounding photosensors measured the scattered light. The time-domain features were evaluated from the acquired scattered light, and then the SVM classifier was trained to distinguish the particle’s data. The real-time detection of the particles was performed with an overall classification accuracy of 96.06%. The optimum conditions were evaluated to detect the particles with a minimum concentration of 0.2 μg/m L. The developed system is anticipated to be helpful in developing rapid testing devices for detecting pathogens ranging between 2 μm to 10 μm.

In this paper, （1） alkaline methanolysis, （2） acid methanolysis, （3） alkaline hydro-lysis, （4） aminolysis of （+）-（R）-（R）-mixed anhydride 1 of O-ethyl phenylphosphonothioic:and O-ethyl O-phenylphosphorothioic acid, （5） its reactions with KSH and （6） with PCl5have been studied. The cleavage of P-O-P bonds in all the reactions studied has beenfound. In reactions （1）-（4）, attacks of nucleophiles occur to the phosphorus atoms of phos-phonyl groups forming the products with inversion of configuration, while the configurationof the phosphorus atoms of phosphoryl groups which are not attacked is retained. Inreaction （5）, the uncleophile -SH attacks the phosphorus atom of the phosphonyl group,but a racemic product results because of the formation of ph（EtO）P（S）- which loseschirality; the configuration of the phosphorus atom of the phosphoryl group which is notattacked is still retained. In reaction （6）, both the phosphonyl and phosphoryl groups arechlorinated giving as products （-）-（R）-thiophophonyl chloride 1

第31届中国过程控制会议（CPCC2020）

作者： Zidong Liu Kun Chen yongjun tang Dongya Zhao Department of Chemical Equipment and Control Engineering College of New Energy China University of Petroleum (East China)

In this paper, the global optimal consensus problems for a double-integrator multi-agent system with communication delays and switching topologies are investigated. Each agent has its own objective function which is only known to itself. Based on zero-gradient-sum(ZGS) scheme, two novel distributed algorithms are proposed to achieve global consensus for time-varying delays with fixed and switching undirected network topologies respectively. The sufficient conditions for global asymptotic stability in terms of linear matrix inequalities(LMIs) are given. Simulation results are given to illustrate the theoretical results.

关键词： Distributed optimization Undirected interconnection topologies Time-varying delays ZGS algorithm Global optimal consensus

国内外学者对关联理论于翻译的强大解释力探讨颇多 ,不过我们不能仅仅满足于这一理论于翻译的解释力 ,因为无论多强大的解释力最终还是要回到翻译这一本体上来。如何有机地将关联理论与翻译理论相结合 ,共同探讨系统的翻译理论并拓展翻译研究领域 ,才显得更有意义。我们借用关联理论来调整和完善对等理论 ,提出了与“最佳关联”一脉相承的“最佳对等”的概念 ,终结了译论研究者争论不休的二元对立式对等概念 ,并且指出 ,关联理论与对等理论的强强结合 ,能达到整合翻译的双重含义——翻译过程和翻译结果 ,为系统、科学的译论建设铺垫基石的目的。

采用铜模吸铸法制备了（Nd0.7Pr0.3）60-x Fe30Al10Cux（x=0,1,2,4）大块非晶合金,利用振动样品磁强计（VSM）研究了该合金的磁性能和磁粘滞行为。结果表明,这几种合金都呈现出较好的硬磁性。随着Cu元素的添加,矫顽力略有增加,但是合金的剩磁却没有变化。利用扫描速率法研究了（Nd0.7Pr0.3）60-x Fe30Al10Cux（x=0,1,2,4）大块非晶合金的磁粘滞行为,得到了这几种合金的相关磁性参数：热扰动场Hf为12.1~15.2 m T,热激活体积va为1.5×10^-18~1.9×10^-18 cm^3。在所研究的合金中都存在明显的铁磁交换耦合作用,同时矫顽力与温度之间的关系符合Gaunt提出的畴壁钉扎模型,合金的硬磁性可能是这两方面共同作用的结果。

提出了基于Shepard曲面、经验模态分解法(ensembleempirical mode decomposition,EEMD)、混沌理论和灰色理论的水电机组状态退化评估与趋势预测模型。该方法首先用Shepard曲面建立综合考虑有功功率、工作水头作用的水电机组状态退化趋势模型。然后将水电机组状态退化趋势进行EEMD分解,得到若干个相对平稳的固有模态函数(intrinsic mode function,IMF)分量和一个余项分量,对每个IMF分量进行特性识别,根据其不同属性,选用混沌预测模型或灰色模型预测,同时对余项分量进行灰色预测。最后将所有分量的预测结果进行重构,获得最终预测结果。实例分析表明,该方法能有效地评估水电机组状态的退化过程,且能提高退化趋势的预测精度。
