Bromate(BrO_3) is a disinfection by-product in drinking water, and its removal is very difficult especially at low levels.60 Co gamma rays were used to remove BrO_3in aqueous solution in this study. The effects of absorbed doses, BrO_3initial concentration, gas saturation, p H value and coexisting anions(Cl, NO 3, SO2 4and HCO 3=CO_3^(2 -))on BrO_3reduction were evaluated. After 4.0-k Gy irradiation of air-equilibrated solution of 30.7 lg/L BrO_3, the residual BrO_3was 8.3 lg/L, which is below the maximum contaminant level of drinking water. The BrO_3reduction rate increased with the dose, in the order of N2[ air [ O_2[ N_2O atmosphere under similar conditions. The results also show that high p H favored the BrO_3removal. According to the experimental results, it can be concluded that the efficiency of decomposing BrO_3by reactive species followed the order of e aq[ H [ HO_2 [ O_2. Coexisting Cl, HCO 3=CO_3^(2 -)and SO2 4ions have little effect on BrO_3removal, whereas NO_3can inhibit its removal as a result of competition with BrO_3for e aq.

A linear delayed position feedback control is applied to control the erosion of safe basins in a Holmes-Duffing system. The conditions of fractal erosion of the safe basin of the controlled system on the basis that the range of time delay leading to good control is obtained by the Melnikov method. It is found that the increasing time delay can reduce the basin erosion under a weak and positive feedback g^in. Then the evolutions of safe basins with time delay are presented in detail by the fourth Runge-Kutta and Monte-Carlo methods, which shows that the safe basin of the controlled Holmes Dulling system can be expanded, and its fractal can be reduced by the increasing time delay. These results suggest that delayed position feedbacks can be used as a good approach to control the erosion of safe basins.

目的探讨经椎间孔腰椎椎间融合术(TLIF)单节段及双节段固定对退行性腰椎滑脱症患者脊柱矢状面参数的影响及其与疗效的关系。方法收集南京医科大学第一附属医院44例(Ⅰ度32例,Ⅱ度12例)经TLIF治疗的退行性腰椎滑脱症患者的临床及影像学资料,根据手术固定节段分为单节段组(29例)和双节段组(15例)。分析比较术前、术后全脊柱侧位X线片的矢状面参数脊柱骶骨角(SSA)、T_1骨盆角(TPA)、腰椎前凸(LL)、骨盆投射(PI)、骨盆倾斜(PT)及骶骨倾斜(SS),以及疼痛视觉模拟量表(VAS)评分、日本骨科学会(JOA)评分及Oswestry功能障碍指数(ODI)。结果全部病例均获得随访,随访时间3~10个月,平均6个月。全组患者术后SSA、TPA、LL、SS均较术前增大,PT较术前减小,差异均有统计学意义(P<0.05),VAS评分、JOA评分和ODI均较术前改善,差异均有统计学意义(P<0.05)。单节段组手术前后LL差值、ODI差值与双节段组比较差异有统计学意义(P<0.05),且2组手术前后LL差值与ODI差值均相关。SSA差值在双节段组与VAS评分差值相关,在单节段组二者无相关性。结论Ⅰ度或Ⅱ度退行性腰椎滑脱症患者通过TLIF治疗可改善脊柱矢状面参数,且单节段固定更有利于术后脊柱矢状面参数的改善。
