利用多源气象资料,通过综合诊断分析方法,对2015年一次广西持续性暴雨过程进行多尺度特征分析。(1)南亚高压经历了双体型构建,副热带长波槽有利于冷空气南下和高空急流的建立。El Nio状态下,副高强度偏强,位置偏西、偏南,有利于暖湿气流向广西输送。南亚高压过渡层与副高对峙,有利于冷暖空气在广西交汇。(2)影响天气系统有高空槽、切变线、冷锋、低空急流、季风槽及低涡等多天气系统。降雨分为锋前暖区、锋面、高空槽加强、季风槽与低涡等四个阶段。(3)中尺度特征为锋前暴雨发生在MCC云团形成到减弱期,雷达强回波呈弓型,对流性强;锋面暴雨发生在MCC减弱后云带,雷达强回波为弓型向直线型转换,对流性减弱;高空槽加强暴雨为直线型云系和雷达回波增强;季风槽与低涡暴雨为增强的涡旋型云系和雷达强回波。(4)暴雨发生在总体地势为云贵高原下坡和地面喇叭口地形辐合的桂西北、海陆分布差异的沿海及山脉迎风坡的桂东南。可见,长时间持续性暴雨过程是一个多尺度和多天气系统相互作用的结果,暴雨发生在有利的大尺度环流背景和天气系统配置下的中小尺度系统频繁发生处,地形助推暴雨作用明显。深刻理解持续性暴雨发生的尺度特征可提高该类天气预报能力。

在有限理性决策者的注意力稀缺性理论下,地方政策的变化取决于地方政府注意力的变动。反之,地方政府注意力是否取决于其他相关政策的变化?论文挖掘2019—2021年我国30个省级地方政府政策文本数据,用文本中词频反映地方政府在数字经济倾注的“注意力”,并应用fsQCA方法探究绿色金融发展是否引起地方政府向数字经济倾注高注意力。研究结论如下:(1)地方政府对数字经济注意力存在“南强北弱”的区域特征。(2)当绿色投资或绿色支持得到发展时,地方政府通过数字技术的应用帮助监测和评估环保项目的效果,实现环境保护、污染治理,助推地方政府向数字经济投入高注意力。(3)当绿色债券和绿色基金同时发展时,作为融资工具,能够有效帮助实体企业获取资金,助力“双碳”,但受公共物品特征影响,很难被反映在企业利润中。并且,绿色债券和绿色基金所应用到的数字手段有限,较难引起高注意力。(4)当绿色金融各个方面发展较弱时,仅绿色债券、绿色权益所能调动的数字技术是不足的,不会促进地方政府向数字经济投入更高注意力。总之,分析绿色金融是否助推地方政府向数字经济投入注意力,对于探索绿色金融和数字经济协同发展路径具有重要意义。

Azoospermia is of great importance to male infertility. Obstructive azoospermia （OA） due to infection is the most prevalent form of OA in China and has been less studied. We aim to observe the treatment outcome of microsurgical vasoepididymostomy （VE） and also to identify the factors relative to the result after reconstructive surgery. Two hundred and eight men presenting with OA due to infection during the study period from July 2010 to July 2013 were prospectively evaluated. Clinical examination, semen analysis, serum follicle stimulating hormone （FSH）, and scrotal ultrasound were done before surgical exploration. Among the 198 men who were selected for surgical procedures, 159 candidates underwent microsurgical VE with sperm detected in the epididymal fluid. As for the other 39 cases, reconstruction was not feasible. The average age was 28.5 ＋ 3.9 years （range 22-38）, with average follow-up being 16.5 ~ 5.9 months （range 4-28）. According to the 150 cases being followed after VE procedures, the total patency rate was 72% （108/150）. During follow-up, 38.7% （58/150） natural pregnancies occurred, with overall live birth rate being 32.7% （49/150）. Our data suggested that microsurgical VE is an effective therapy for postinfectious epididymal OA. Individualized counseling with prognosis based on etiology should be offered to patients to select optical therapy.
