This work proposes an improved multi-objective slime mould algorithm, called IBMSMA, for solving the multi-objective truss optimization problem. In IBMSMA, the chaotic grouping mechanism and dynamic regrouping strategy are employed to improve population diversity;the shift density estimation is used to assess the superiority of search agents and to provide selection pressure for population evolution;and the Pareto external archive is utilized to maintain the convergence and distribution of the non-dominated solution set. To evaluate the performance of IBMSMA, it is applied to eight multi-objective truss optimization problems. The results obtained by IBMSMA are compared with other 14 well-known optimization algorithms on hypervolume, inverted generational distance and spacing-to-extent indicators. The Wilcoxon statistical test and Friedman ranking are used for statistical analysis. The results of this study reveal that IBMSMA can find the Pareto front with better convergence and diversity in less time than state-of-the-art algorithms, demonstrating its capability in tackling large-scale engineering design problems.

In this paper, different concentrations of CsOH solution(salt/water molar ratios are 1:50, 1:15 and saturated solution) were subjected to X-ray total scattering experiment. Each sample was measured at three different temperatures(283 K, 298 K, 323 K). Model calculation analysis were then performed. The average distance of Cs-O(W, I)(“W, I” is the meaning of the first coordination shell) was found to be ～0.329 nm, and the coordination number was ～6.3. The coordination number of O-O in H-bonding was 2.23, and the coordination distance was ～0.272 nm. The coordination distance of the intermolecular interaction increased with the concentration increasing, but the coordination number became smaller. The laws were not uniform for each solution as the temperature changing. Three different concentrations represented different internal properties of the solution, and the characteristics of ions in the solution could be further understood by analyzing the model calculation results.

糖皮质激素(glucocorticoids,GCs)作为一类环境内分泌干扰物,引起了环境领域越来越多的关注。由于缺乏有效控制水中GCs污染的技术,本研究搭建了并联等离子体射流耦合活性碳纤维系统(paralleling plasma jet/activated carbon fiber,PPJ/ACF)以有效降解水中的糖皮质激素氟轻松(fluocinolone acetonide,FA)。当PPJ/ACF系统的放电功率为49.7W、ACF投加量为3g/L时,处理60min后,FA的去除率可达96%,能量利用率为96mg/kWh,能耗量为0.36kWh/L。PPJ与ACF联用有显著的协同效应,ACF可提供催化位点及吸附GCs位点,PPJ可原位释放ACF吸附位点。通过添加自由基抑制剂,发现羟基自由基(·OH)是降解FA的主要作用自由基。通过超高效液相色谱飞行时间质谱联用仪(ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer,UHPLC-QTOF)检测分析了FA可能的中间产物,根据中间产物分析FA的降解途径主要包括脱氟、酮酸脱羧、脱甲基、分子内环化、裂解和酯水解,表明FA毒性降低。因此,PPJ/ACF系统可有效控制GCs污染。

Density, pH, viscosity, conductivity and the Raman spectra of aqueous NaB（OH）4 solutions precisely measured as functions of concentration at different temperatures （293.15, 298.15, 303.15, 313.15 and 323.15 K） are presented. Polyborate distributions in aqueous NaB（OH）4 solution were calculated, covering all the concentration range, B（OH）4 is the most dominant species, other polyborate anions are less than 5.0%. The volumetric and the transport properties were discussed in detail, both of these properties indicate that B（OH）4 behaves as a struc- ture-disordered anion.
