Construction of heterojunction has been considered as an efficient strategy to enhance the gas-sensing performances of metal oxide *** this basis,hierarchical In_(2)O_(3)/In_(2)S_(3) microsphere heterostructures were synthesized by partial oxidation of In_(2)S_(3) precursors which were obtained via a facile hydrothermal ***,gas sensors based on the acquired materials were fabricated to investigate their sensing performances toward triethylamine(TEA).The results reveal that the gas sensor based on In_(2)O_(3)/In_(2)S_(3) exhibits a high response of 37 at 300℃ toward 0.45 mg/L TEA,which is 3.7 times higher than that of bare In_(2)O_(3).Meanwhile,it also possesses fast response/recovery time(19 s/154 s),good repeatability,selectivity and long-term *** excellent sensing performances toward TEA are mainly attributed to the massive oxygen vacancy defects and heterojunction formed between In_(2)O_(3) and In_(2)S_(3).This work provides a facile temperature-dependent route to controllably synthesize hierarchical In_(2)O_(3)/In_(2)S_(3) microsphere heterostructures,and the In_(2)O_(3)/In_(2)S_(3) sensor shows great application prospects in TEA detection.

控制理论与应用（英文版） 2008年第3期6卷 322-326页

A fuzzy neural network controller for underwater vehicles has many parameters difficult to tune manually. To reduce the numerous work and subjective uncertainties in manual adjustments, a hybrid particle swarm optimization （HPSO） algorithm based on immune theory and nonlinear decreasing inertia weight （NDIW） strategy is proposed. Owing to the restraint factor and NDIW strategy, an HPSO algorithm can effectively prevent premature convergence and keep balance between global and local searching abilities. Meanwhile, the algorithm maintains the ability of handling multimodal and multidimensional problems. The HPSO algorithm has the fastest convergence velocity and finds the best solutions compared to GA, IGA, and basic PSO algorithm in simulation experiments. Experimental results on the AUV simulation platform show that HPSO-based controllers perform well and have strong abilities against current disturbance. It can thus be concluded that the proposed algorithm is feasible for application to AUVs.

膨胀土是一种亲水性较强的特殊土,遇水易发生胀缩变形,导致修建在膨胀土地区的路基常产生路面开裂、沉降、翻浆等病害。新型土工织物是一种具有排水与加筋功能的新型土工材料,除像传统排水结构一样能排“明水”外,其毛细织物沟槽产生的毛细力还能排毛细水,在非饱和环境下排水效率高。为研究新型土工织物对膨胀土水分迁移的影响规律,通过在膨胀土中设置一层土工织物,开展毛细水上升、降雨入渗条件下素土(素土样)、新型土工织物排水(排水样)及不排水(阻隔样)3种工况的一维土柱对比试验,探索新型土工织物对膨胀土的含水率(体积、质量)、膨胀率及不排水强度的影响规律。研究结果表明:膨胀土与新型土工织物形成的阻隔系统使得更多的水分集聚在土工织物周围,产生了类似“锅盖”的效应;在膨胀土中铺设新型土工织物,能延缓水分迁移速率和抑制胀缩变形,膨胀土的不排水抗剪强度发生了显著变化;阻隔样中新型土工织物将水分吸附、阻滞在其周围不能排出,易造成病害,排水样中试样内外湿度差产生的吸力差将“抽吸”到新型土工织物毛细沟槽中的水分横向导出;为充分发挥新型土工织物在非饱和环境下的排水效率,需将其延伸至土样外。研究成果可为膨胀土路基设计、施工及病害处治提供参考。
