探讨NO_(2)^(−)对高铁酸盐(Fe(Ⅵ))降解4-氯-3,5-二甲基苯酚(PCMX)的动力学、产物和毒性的影响.结果表明,在pH7~9范围内,Fe(Ⅵ)能有效降解水中的PCMX,在[Fe(Ⅵ)]:[PCMX]=10:1的条件下,PCMX在5min内的降解率可达100%.0.1~10mg/L的腐殖酸(HA)明显促进了PCMX的降解;而NO_(2)^(−)的引入则显著抑制了反应过程,并导致多种硝基副产物的生成.淬灭实验结果表明,高价铁是反应过程中的主要反应物种.毒性预测显示,生成的硝基副产物和偶联产物具有持久性和生物毒性,如OP-6和OP-7的半衰期超过180d,生物富集因子大于5000,慢性毒性值小于1mg/L,可能带来一定的环境风险.

The appropriate terminal attitude of missile is important to improve the damage effectiveness of fragmentation warhead against aircraft *** this paper,three missile terminal attitude selection methods are proposed to solve the problem of terminal attitude selection in different situations according to their respective evaluation *** MVE-based method uses the damage probability of each detonation point around the aircraft at a given attitude of missile to calculate the Mean Volume of Effectiveness(MVE)at the corresponding attitude,and then uses the MVE for different attitudes to select the terminal strike *** detonation position-based method addresses the case where the missile detonation position can be assessed in *** the effects of missile guidance errors and fuze activation position errors,Monte Carlo simulations are used to calculate the damage probability of aircraft with different strike attitudes,from which the terminal strike attitude is *** BP-ANN model-based method uses the constructed Back Propagation Artificial Neural Network(BP-ANN)model instead of simulation to calculate the evaluation indexes in the corresponding cases of MVE-based method and Detonation position-based method,which can improve the efficiency of attitude *** are conducted for different scenarios to verify the feasibility and effectiveness of the proposed method.

葡萄膜炎基础研究虽已获很大进展，但尚有许多问题和难题未解决，如机体防御葡萄膜炎机制（前房相关免疫偏离）形成的分子和细胞学基础、人类葡萄膜炎与动物模型在临床病程上差异的原因和机制、感染因素引起自身免疫反应与葡萄膜炎的机制及葡萄膜炎易感基因等尚不完全清楚。利用我国Behcet病、Vogt-小柳原田综合征患者资源优势，整合力量，集中对它们的发病机制进行深入研究，有望为葡萄膜炎防治研究寻找到新的切人点。
