The shrinking Arctic sea-ice area(SIA) in recent decades is a striking m.nifestation of the ongoing clim.te *** of the Arctic sea ice have been continuously observed by satellites since 1979, relatively well m.nitored since the 1950s, but are highly uncertain in the earlier period due to a lack of observations. Several reconstructions of the historical gridded sea-ice concentration(SIC) data were recently presented based on synthesized regional sea-ice observations or by applying a hybrid m.del–em.irical approach. Here, we present an SIC reconstruction for the period1901–2019 based on established co-variability between SIC and surface air tem.erature, sea surface tem.erature, and sea level pressure patterns. The reconstructed sea-ice data for m.rch and Septem.er are com.ared to the frequently used Had ISST1.1 and SIBT1850 datasets. Our reconstruction shows a large decrease in SIA from.the 1920 to 1940 concurrent with the Early 20th Century Warm.ng event in the Arctic. Such a negative SIA anom.ly is absent in Had ISST1.1 data. The am.litude of the SIA anom.ly reaches about 0.8 m.n km.(2) in m.rch and 1.5 m.n km.(2) in Septem.er. The anom.ly is about three tim.s stronger than that in the SIBT1850 dataset. The larger decrease in SIA in Septem.er is largely due to the stronger SIC reduction in the western sector of the Arctic Ocean in the 70°–80°N latitudinal zone. Our reconstruction provides gridded m.nthly data that can be used as boundary conditions for atm.spheric reanalyses and m.del experim.nts to study the Arctic clim.te for the first half of the 20th century.

鉴于当前硫系光纤在高功率传输与高光束质量难以同时实现的问题。我们通过COm.OL软件仿真模拟光纤性质，设计出了满足单模传输且具有大模场面积的光子晶体光纤(PCF)的结构参数。所设计的光纤在1.5-10μm.范围内满足高阶模(LP11)与基模(LP01)的限制损耗比大于102的单模条件，且光纤基模的有效模面积在2μm.约为5362μm.。根据仿真模拟的结构参数，探索出新型动、静态蒸馏相结合的技术制备出高纯硫系玻璃，结合新型的挤压-堆积法，制备出基于全硫系玻璃的全固态大模场单模光子晶体光纤。该光纤在波长1.55μm.的近高斯光能量分布特征验证了其单模特性；同时在弯曲半径为14cm.1.5m.的光纤中观察到低弯曲损耗为1 dB，与仿真结果基本一致，表明此全固态光子晶体光纤具有出色的单模传输和抗弯性能，在中红外高能激光传输方面具备了一定的应用潜能。

阿尔泰山南坡受到西风急流、北冰洋冷湿气流、蒙古-西伯利亚高压和亚洲低压共同影响,形成了当地特有的气候模式;同时,阿尔泰山地区是欧亚沟通的枢纽地带,气候变化对周边人类生产生活以及生态系统影响显著。因此有必要了解阿尔泰山周边气候变化长期历史,识别气候变化特征,总结规律以应对未来气候变化带来的灾害。本研究利用相关分析发现阿尔泰山南坡西伯利亚落叶松树轮宽度年表与夏季(6~7月)温度呈显著关系(r=0.626,n=58,p<0.001),进而建立一阶线性回归模型方程定量重建了阿尔泰山南坡过去304年(1715~2018年)夏季温度变化。统计结果显示重建序列稳定可靠,并有能力代表大范围的温度变化特征。重建存在5个暖期(1740~1767年、1775~1793年、1837~1847年、1898~1909年、1990~2018年)和5个冷期(1715~1727年、1807~1828年、1848~1858年、1876~1897年、1927~1940年)。虽然自1990年来温度持续上升(1990~2018年温度距平0.33℃),但并未超过1740~1767年的温度(温度距平0.49℃)。结合周边降水重建序列,发现研究区域在过去3个多世纪表现出夏季水热同步的配置模式,即暖湿/冷干模态占主导地位。
