Monitoring of benzene, toluene and xylenes （BTEX） was conducted along with traffic counts at 17 roadside sites in urban areas of HoChiminh. Toluene was the most abundant substance, followed by p,m-xylenes, benzene, o-xylene and ethylbenzene. The maximum observed hour-average benzene concentration was 254 μg/m3 . Motorcycles contributed to 91% of the traffic fleet. High correlations among BTEX species, between BTEX concentrations and the volume of on-road motorcycles, and between inter-species ratios in air and in gasoline indicate the motorcycle-exhaust origin of BTEX species. Daily concentrations of benzene, toluene, ethylbenzene, p,m-xylenes and o-xylene were 56, 121, 21, 64 and 23 μg/m 3 , respectively. p,m-xylenes possess the highest ozone formation potential among the BTEX family.

高放废物处置库中回填材料需要预先压缩到一定密实度,其压缩特性对处置库的设计和安全性有重要影响。目前,粉碎后的Callovo-Oxfodian(COx)黏土岩(法国)被考虑为可选的回填材料之一。通过开展一维压缩试验,研究2种不同粉碎工艺下获得的粗/细COx土样的压缩特性,结果表明:压缩曲线受粒度成分的影响非常明显,为获得同等压实度,细粒土所需的压实功能较粗粒土高,除此之外,细粒土的压缩指数也高于粗粒土,表现出较强的压缩性;随着土样压实密度的增加,粗/细土样的压缩曲线逐渐靠拢,粒度成分对压实功能影响逐渐减弱;土样卸荷时回弹指数随干密度的增加而增加,受粒度成分的影响不明显;高压实(ρd=2.0g/cm3)粗粒土样在7MPa的轴向应力下饱和时,体积发生明显的塌陷现象,饱和后土样的压缩指数小于饱和前,而回弹指数则较饱和前高。

In this paper, a new adaptive hierarchical sliding mode control scheme for a 3D overhead crane system is proposed. A controller is first designed by the use of a hierarchical structure of two first-order sliding surfaces represented by two actuated and un-actuated subsystems in the bridge crane. Parameters of the controller are then intelligently estimated, where uncertain parameters due to disturbances in the 3D overhead crane dynamic model are proposed to be represented by radial basis function networks whose weights are derived from a Lyapunov function. The proposed approach allows the crane system to be robust under uncertainty conditions in which some uncertain and unknown parameters are highly difficult to determine. Moreover, stability of the sliding surfaces is proved to be guaranteed. Effectiveness of the proposed approach is then demonstrated by implementing the algorithm in both synthetic and reallife systems, where the results obtained by our method are highly promising.
