In the present work, surface diurnal warming strength in the East China Sea was calculated by the sea surface temperature(SST) data derived from the MODIS sensors carried by the satellites Aqua and Terra. Due to transit time difference, both the number of valid data and the surface diurnal warming strength computed by the MODIS-Aqua data are relatively larger than Terra. Therefore, the 10-year MODIS-Aqua data from 2005 to 2014 were used to analyze the monthly variability of the surface diurnal warming. Generally, the surface diurnal warming in the East China sea is stronger in summer and autumn but weaker in winter and spring, while it shows different peaks in different regions. Large events with ΔT≥5 K have also been discussed. They were found mainly in coastal area, especially near the Changjiang(Yangtze) River estuary. And there exists a high-incidence period from April to July. Furthermore, the relationship between surface diurnal warming and wind speed was discussed. Larger diurnal warming mainly lies in areas with low wind speed. And its possibility decreases with the increase of wind speed. Events with ΔT ≥2.5 K rarely occur when wind speed is over 12 m/s. Study on surface diurnal warming in the East China Sea may help to understand the daily scale air-sea interaction in the shelf seas. A potential application might be in the marine weather forecasts by numerical models. Its impact on the coastal eco-system and the activities of marine organisms can also be pursued.展开更多
目的系统评价3D打印技术联合经皮肾镜取石术(PCNL)治疗肾结石的有效性和安全性。方法计算机检索中国知网、维普智立方、万方数据知识服务平台、中国生物学文献服务系统、PubMed、The Cochrane Library、Embase、Web of Science等数据库...目的系统评价3D打印技术联合经皮肾镜取石术(PCNL)治疗肾结石的有效性和安全性。方法计算机检索中国知网、维普智立方、万方数据知识服务平台、中国生物学文献服务系统、PubMed、The Cochrane Library、Embase、Web of Science等数据库,检索关于3D打印技术联合PCNL治疗肾结石的随机对照试验和/或病例对照试验,检索时限均为建库至2021年3月8日。筛选文献和质量评价后,采用RevMan 5.4软件进行Meta分析。结果最终纳入9篇文献。Meta分析结果显示,观察组清石率、一次穿刺成功率均高于对照组,住院时间、并发症发生率、术中出血量均短于或少于对照组(均P<0.05),但两组的手术时间差异无统计学意义(P>0.05)。结论3D打印技术联合PCNL能够提高肾结石患者的清石率和一次穿刺成功率,缩短或降低住院时间、并发症发生率及术中出血量,效果优于单独使用PCNL。展开更多
