| 1 | 土壤中3,4-二氯苯胺降解动力学及其生态毒性显示文摘敌草隆 ( diuron)是一种广泛被应用的取代脲类除草剂 ,其主要降解产物为 3,4-二氯苯胺 [1 ] .研究 3,4-二氯苯胺在不同土壤中的降解动力学规律 ,并用土壤环境指示动物弹尾目 ( Collembola)跳虫 ( Folsomia candida)跟踪指示该化合物在进一步降解过程中的毒性 .结果表明 :3,4-二氯苯胺在土壤中的降解行为可用一级反应动力学方程来较好地描述 ,其生态毒性明显高于母体化合物敌草隆 ,该化合物在粘土中的残留量低于砂土 ,但毒性却明显大于砂土 ,指出应注重同步研究农药降解产物的环境化学及生态毒性行为 . | 蒋新 周建民 P.Müller | 2000 | 环境科学2000，21，5： | 4 |
| 2 | Robotic pancreaticoduodenectomy after the learning curve-a new hope显示文摘First,we would like to congratulate Liu et al.for their successful multicenter study including 1,032 patients undergoing robotic pancreaticoduodenectomy(RPD)and 1,154 open pancreaticoduodenectomy(OPD)in seven high volume centers in China over an 8 year period(1).To ensure the best possible outcomes of both techniques,RPD was performed by five surgeons from three centers after overcoming the individual learning curve that was defined as having performed>40 RPD.On the other hand,OPD was performed by 9 surgeons from 6 centers after reaching the individual learning curve,defined as an experience of>60 OPD. | Philip C.Müller Beat P.Müller-Stich Thilo Hackert Felix Nickel | 2022 | Hepatobiliary Surgery and Nutrition2022，11，3： | 0 |
