Temperature-dependent Kinetics on Laser Induced Photolysis of Aqueous CS_2-HONO Solutions

引用

Chinese Chemical Letters 2005年第10期16卷 1364-1366页

作者： hao Jie FANG cheng zhu zhu Wen Bo DONG Hui Qi HOU Environment Science Institute Fudan University Shanghai 200433

A laser photolysis/transient absorption technique has been employed to investigate the photolysis kinetics of aqueous CS2-HONO solutions at 355 nm. Spectral analysis shows that CS2OH will react with HONO to form CS2OH-HONO. Temperature dependent rate coefficients for the reaction are reported for the first time. The following Arrhenius expressions adequately summarize the kinetic data obtained over the temperature range 273-313 K （units are L·mol^-1·s^-1）： In k = （31.6±0.6）-{（4.1±0.2）×10^3/T}, and the activation energy in unit of *** is 32.47 with the temperature accuracy 0.2 K.

综采放顶煤开采中,工作面采用预留煤柱沿空掘巷,常常遇到协调掘进巷道设计与煤柱变形之间的关系问题.解决这一问题,一方面关系到资源的采出率,另一方面涉及到生产安全.针对煤柱变形的时效性,通过分析综放工作面沿空一侧区段小煤柱的受力与变形规律,引入统计损伤变量概念,建立了基于统计损伤的区段煤柱流变模型;进一步结合能量原理,分析了区段煤柱流变损伤条件下的时间相关性,给出了区段煤柱变形时间定量化表达式,得到了区段煤柱统计损伤的最小失稳计算公式.应用理论分析结果,在现场工程实践中,对煤柱变形与稳定性进行了预测,其结果与现场实测结果一致.

公共建筑空间人员密集、人流量大,空气污染种类多并呈现非均匀动态的分布特性,给新冠肺炎疫情常态化空气安全保障带来了巨大挑战.采用过量送风不仅可能造成较大能源浪费,同时也可能导致交叉污染.从人因工程学的核心理念和基本方法出发,围绕室内空气污染水平(特别是人员散发的飞沫污染物)这一重要人因环境变量,发展了一套建筑空气环境安全运维控制系统.该系统基于室内空气污染和人员流动的动态监测,由快速预测模型以及计算机视觉处理得到室内污染与人员的非均匀动态分布,进一步通过环境控制决策系统输出最优通风参数设定,实现通风智能化调控;同时,在通风环境营造基础上构建空气净化消杀系统,对空气环境安全运维形成有力的辅助保障.最后,通过实际案例(某国际会议中心前厅)详细展示了该系统的工作流程和设计效果.设计结果显示,实施智能化通风可将人员感染风险降低至4%以内,其通风节能率可达44.9%;负氧离子的空间可达性较好且空间消杀率计算值超过99%,可进一步降低感染风险.

Modification of Maxwell model for conductivity prediction of carbon nanotubes-filled polymer composites with tunneling effect

引用

Applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 25-36页

作者： Jue zhu Longyuan LI Ningtao zhu Zhejiang Provincial Engineering Research Center for the Safety of Pressure Vessel and Pipeline Key Laboratory of Impact and Safety Engineering (Ningbo University) Ministry of Education School of Engineering Computing and Mathematics University of Plymouth Xi'an Zhanshi Testing & Engineering Co.Ltd.

Carbon nanotubes(CNTs) have garnered great attention in recent years due to their outstanding electrical, thermal, and mechanical properties. The incorporation of small amounts of CNTs in polymers can substantially improve the sensitivity of the polymer's electrical conductivity. This paper presents a modified Maxwell model to evaluate the electrical conductivity of CNTs-filled polymer composites by introducing a transition zone to account for the tunneling effect. In this modified Maxwell model, the CNTs-filled polymer composite is modeled as a three-phase composite, consisting of a matrix(polymer), inclusions(CNTs), and a transition zone(tunneling zone). The effective electrical conductivity(EEC) of the composite is calculated based on the volume fractions and electrical conductivities of the matrix, inclusions, and transition zone. The model's validity is confirmed through the use of available test data, which demonstrates its capability to accurately capture the nonlinear conductivity behavior observed in CNTs-polymer composites. This study offers valuable insights into the design of high-performance conductive polymer nanocomposites, and enhances the understanding of electrical conduction mechanisms in CNT-dispersed polymer composites.

The dominant annual cycle of sea surface temperature(SST)in the tropical Pacific exhibits an antisymmetric mode,which explains 83.4%total variance,and serves as a background of El Niño-Southern Oscillation(ENSO).However,there is no consensus yet on its anomalous impacts on the phase and amplitude of *** on data during 1982-2022,results show that anomalies of the antisymmetric mode can affect the evolution of ENSO on the interannual scale via Bjerknes feedback,in which the positive(negative)phase of the antisymmetric mode can strengthen El Niño(La Niña)in boreal winter via an earlier(delayed)seasonal cycle transition and larger(smaller)annual *** magnitude of the SST anomalies in the equatorial eastern Pacific can reach more than±0.3◦C,regulated by the changes in the antisymmetric mode based on random sensitivity *** reveal the spatial pattern of the annual cycle associated with the seasonal phase-locking of ENSO evolution and provide new insight into the impact of the annual cycle of background SST on ENSO,which possibly carries important implications for forecasting ENSO.
