This study explores the characteristics of high temperature anomalies over eastern China and associated influencing factors using observations and model *** show that more long-duration（over 8 days） high temperature events occur over the middle and lower reaches of the Yangtze River Valley（YRV） than over the surrounding regions,and control most of the interannual variation of summer mean temperature in *** synergistic effect of summer precipitation over the South China Sea（SCS） region（18°–27°N,115°–124°E） and the northwestern India and Arabian Sea（IAS） region（18°–27°N,60°–80°E） contributes more significantly to the variation of summer YRV temperature,relative to the respective SCS or IAS precipitation *** precipitation（enhanced condensational heating） over the SCS region strengthens the western Pacific subtropical high（WPSH） and simultaneously weakens the westerly trough over the east coast of Asia,and accordingly results in associated high temperature anomalies over the YRV region through stimulating an East Asia–Pacific（EAP） *** precipitation over the IAS region further adjusts the variations of the WPSH and westerly trough,and eventually reinforces high temperature anomalies over the YRV ***,the condensational heating related to more IAS precipitation can adjust upper-tropospheric easterly anomalies over the YRV region by exciting a circumglobal teleconnection,inducing cold horizontal temperature advection and related anomalous descent,which is also conducive to the YRV high temperature *** reproduction of the above association in the model results indicates that the above results can be explained both statistically and dynamically.

研究了抗坏血酸/过硫酸盐去除土壤中阿特拉津的效率、影响因素及机理。当抗坏血酸和过硫酸盐浓度分别为10,30 mmol/L,初始pH为3.0时,土壤中阿特拉津降解率达到92.4%。共存的无机阴离子(Cl-和HCO_(3)^(-))会抑制阿特拉津的降解。低浓度溶解态有机质(0~2.5 mg/L)能促进阿特拉津的氧化降解,高浓度溶解态有机质(>5 mg/L)会抑制阿特拉津的氧化降解。抗坏血酸一方面直接诱导过硫酸盐活化产生硫酸根自由基(SO_(4)^(-)·)和羟基自由基(·OH),另一方面促进土壤释放铁离子和Fe^(2+)/Fe^(3+)的循环,从而间接增强过硫酸盐的活化性能。此外,抗坏血酸增强了土壤中阿特拉津的解吸,降低了阿特拉津与氧化性自由基的传质阻力,有利于提升阿特拉津的氧化降解效率。抗坏血酸/过硫酸盐体系降解阿特拉津主要包括脱烷基氧化、脱氯和羟基化3种途径。
