空分塔爆炸事故树分析

本运用事故树分析(FTA)，根据大量事故案例和导致空分塔爆炸的条件，以空分塔爆炸事故为顶上事件，采用布尔代数运算法则求解，得到18个最小割集，然后经过运算，得到结构重要顺序。为了避免空分塔爆炸事故的发生，空分塔有良好的静电接地和防止空分塔内乙炔超量是非常重要的。该事故树分析为空分塔的安全生产提供了重要的依据。

染料生物吸附影响因素与解吸条件研究

用筛选出的一株丝状真菌(GX2)对活性、酸性、碱性和直接染料进行吸附及解吸的试验结果表明，该菌株对活性、酸性和直接染料有较高的吸附率，但碱性染料难被吸附；在多种有机溶剂中，丙酮是较好的解吸剂，碱性介质有利于染料的解吸；对菌体进行破碎及在解吸过程中加以搅拌有利于解吸过程的进行。     

Numerical Simulation of Synoptic Condition on a Severe Sand Dust Storm

By using observational data and MM5, an observational analysisand numerical study was conducted on the synoptic condition of a severe dust storm that was caused by a Mongolian cyclone whichoccurred from 6 to 8 April 2001. Results illustrated thatthe cyclogenesis was due to the isentropic potential vorticity (IPV) advection in the upper troposphere and the terrain modifiedbaroclinicity in the mid-lower troposphere. The Altai-Sayan complex of mountains blocked the lower level cold air and made the isentropic surface sharply steep. When the air slid down along the isentropic surface the increasing of baroclinicity anddecreasing of stability blew up the vertical vorticity development.The formation of the dust storm was a result of a cyclonic cold front passing across the area. The occurrence of this dust stormwas closely related to the strong surface wind, which was accompanied by a cold front passing, rather than the cyclogenesis, itself. Hence, the reason for the pre-front dust storm formulation was the formation of heating convection. Reasons behind the formation of a black storm (visibilitylower than 50 m), which occurred in the mid-north part ofInner Mongolia, lay in several aspects. Firstly, in thisarea the surface wind was strong, a direct result of thedownward transport in mid-lower troposphere. Secondly,the cold front passed over the effected area near sunsetso the air obtained much more surface heating to form adeeper mixed layer (ML). Thirdly, cooperation between thelower level wind and the terrain made the atmosphere inthis area and acquired the maximum advective contributionnecessary to form a deep post-front ML. The sensitivityexperiment revealed that surface heat flux was important to the frontal lifting. In addition, the forcing of surface heating wasalso seen as the primary forcing mechanism of frontogenesis. Meanwhile, removal of the surface heat flux made the atmosphericstratification became stable and the pre-storm ML very shallow,which weakened the strength of the dust storm.
