ADN氧化剂的合成及其在推进剂中的应用

综述了ADN的合成、性质及其在推进剂中的应用，认为球形ADN具有能量高、感度低、特征信号低，对环境无污染等优点，将其作为氧化剂在高能低特征信号推进剂中有着广阔的应用前景。     

The Cooperative Molecular Field Effect

Two‐dimensional arrangements of molecules can show remarkable cooperative electronic effects. Such effects can serve to achieve direct electronic sensing of chemical and physical processes via electrostatic effects, i.e., without transfer of charge or matter between the locus of sensing and that of detection.     

构造作用对油气生成和运聚的影响

有机质从埋藏开始，就处于极其复杂的地球物理化学场中，环境提的能量，一是热量，二是机械能，机械能，主要是通过机械力作用传递给系统的，另外还以机械波的形式赋予系统一定的机械能。当发生断褶构造运动时，机械力对油气运移的影响尤为突出，它经能量的迁移转化，促成了包括机械力降解和地应力驱动等一系列的连锁反应，制造了一次次高效的成油（生运）事件，本文以突变论为着眼点，按照改造控制建造的思路，大胆提出构造运动制造生排烃事件，成就含油气系统的假说。

微滤膜清洗的研究

用次氯酸钠溶液、氢氧化钠溶液和盐酸溶液对小型微滤膜进行化学清洗试验,比较试验结果认为,用次氯酸钠溶液对受污染的微滤膜清洗更为有效,从而为鄂尔多斯羊绒集团污水处理厂中的大型连续微滤化学清洗提供依据.     

在酸性介质中N-H伪酸Mannich反应机理的量子化学研究

用量子化学中的ＳＣＦ－ＭＯＡＭ１方法，全优化计算了以苯并唑酮为伪酸组分的（Ｎ－Ｈ酸）Ｍａｎｎｉｃｈ反应的反应物、过渡态和产物络合物的分子几何构型、电子结构和生成热。根据计算所得各反应的活化能，提出了该反应在酸性介质中的机理，即甲醛首先与苯并唑酮作用，其产物再与二甲胺作用生成Ｍａｎｎｉｃｈ碱，并就其缘由进行了讨论。     

Analysis of trace mercury in water by solid phase extraction using dithizone modified nanometer titanium dioxide and cold vapor atomic absorption spectrometry

A new method for analysis of trace mercury in water samples was developed, based on the combination of preconcentration/separation using dithizone-modified nanometer titanium dioxide (TiO2) as a solid phase extractant and determination by cold vapor atomic adsorption spectrometry (CVAAS). Dithizone was dissolved with alcohol and loaded on the surface of nano-sized TiO2 powders by stirring. The static adsorption behavior of Hg2 on the dithizone-modified nanoparticles was investigated in detail. It was found that excellent adsorption ratio for Hg2 could be obtained in the pH range of 7-8 with an oscillation time of 15 min, and a 5 mL of 3.5 mol·L-1 HCl solution could quantitatively elute Hg2 from nanometer TiO2 powder. Common coexisting ions caused no obvious influence on the determination of mercury. The mechanisms for the adsorption and desorption were discussed. The detection limit (3σ) for Hg2 was calculated to be 5 ng·L-1. The proposed method was applied to the determination of Hg2 in a mineral water sample and a Zhujiang River water sample. By the standard addition method, the average recoveries were found to be 94.4%-108.3% with RSD (n = 5) of 2.9%-3.5%.
