To test superconducting cavities, a vertical test system has been designed and set up at the Institute of Modern Physics （IMP）. The system design is based on VCO-PLL hardware and the NI Labview software. The test of the HWR010#2 superconducting cavity shows that the function of this test system is satisfactory for testing the low frequency cavity.

*** In July 2018,the Antarctic community came together to meet at the 13th Workshop on Antarctic Meteorology and Climate(WAMC)in Madison,Wisconsin,USA(Fig.1);and in the following year in June 2019,the 14th WAMC was held in Charleston,South Carolina,USA(Fig.2).With a growing history,the WAMC addresses the topics of Antarctic meteorology and climate(Kameda et al.,2008;Colwell et al.,2016;Lazzara et al.,2018)as well as weather-related issues of scientific and operational *** workshops bring together researchers,operational forecasters,numerical modelers,observational specialists,and *** themes of both workshops included Antarctic meteorological observations,Antarctic atmospheric numerical modeling,Antarctic meteorological and climate research,and Antarctic weather forecasting and operational *** 2018 and 2019 WAMC were both followed by a one-day focus on the Year of Polar Prediction-Southern Hemisphere(YOPP-SH),when preparations and follow-up discussions were made with regard to the YOPP Special Observing Period from 16 November 2018 to 15 February 2019.

天津周大福金融中心跻身世界第八和中国第四高摩天楼,以530m的高度刷新中国北方(长江以北)的建筑高度记录。这座103层的多用途建筑包含办公楼层、300套服务式公寓单元和一家拥有350套客房的五星级酒店。建筑采用层层叠加并逐渐减小的楼板设计,大楼的锥形外形犹如一把利剑直插云霄,在设计上兼顾美学且富含视觉冲击力,同时大大减少了大楼的外墙表面积。这一新颖的设计充分考虑到天津滨海新区风力为建筑带来的阻力,更符合空气动力学,可以有效减少涡旋发散现象,最大程度地降低风荷载,同时降低大楼在日照下的暴晒面积和雨水的侵袭。

目的:观察补充外源性抗氧化剂对急性心脑血管意外老年病人血浆谷胱甘肽过氧化物酶(GSH-Px)的活性、维生素A(VitA)、维生素C(VitC)、维生素E(VitE)和硒(Se)水平的影响。方法:对105例急性心脑血管意外老年病人随机分为试验组(加用抗氧化剂... 详细信息

目的:观察补充外源性抗氧化剂对急性心脑血管意外老年病人血浆谷胱甘肽过氧化物酶(GSH-Px)的活性、维生素A(VitA)、维生素C(VitC)、维生素E(VitE)和硒(Se)水平的影响。方法:对105例急性心脑血管意外老年病人随机分为试验组(加用抗氧化剂)和对照组(服用安慰剂)。两组病人均每天服用1次,连续6周。两组病人在治疗前、治疗后3周和6周,清晨空腹采取肘静脉血3 ml。检测血浆GSH-Px活性、VitA、VitC、VitE和Se的水平变化。结果:治疗3周和6周后,试验组病人血浆GSH-Px活性,VitC、VitE和Se水平较对照组明显升高(P<0.05)。试验组病人治疗6周后VitA水平较对照组明显升高(P<0.05)。结论:对急性心脑血管意外老年病人补充外源性抗氧化剂,可在短时间内增加血浆VitA、VitC、VitE、Se的含量和GSH-Px的活性。
