Journal of Materials Science & Technology 2002年第4期18卷 351-353页

Northeastern Univ. Shenyang 110004 China Inst. of Metal Res. Chinese Acad. of Sci. Shenyang 110016 China

The corrosion resistance of 2024 Al and SiC particle reinforced 2024 Al metal matrix composite (SiCp?024AI MMC) in 3.5% NaCl solution was investigated with electrochemical method and immersion test, and the corrosion protection of sulfuric acid anodized coatings on both materials was evaluated by electrochemical impedance spectroscopy. The results showed that the SiCp?024AI MMC is more susceptible to corrosion than its matrix alloy in 3.5% NaCI. For 2024AI, the anodized coating provides excellent corrosion resistance to 3.5% NaCI. The anodized coating on the SiCp?024AI provides satisfactory corrosion protection, but it is not as effective as that for 2024AI because the structure of the anodized layer is affected by the SiC particulates.

Drone-based entanglement distribution towards mobile quantum networks

National Science Review 2020年第5期7卷 921-928页

Satellites have shown free-space quantum-communication ability; however, they are orbit-limited from full-time all-location coverage. Meanwhile, practical quantum networks require satellite constellations,which are complicated and expensive, whereas the airborne mobile quantum communication may be a practical alternative to offering full-time all-location multi-weather coverage in a cost-effective way. Here,we demonstrate the first mobile entanglement distribution based on drones, realizing multi-weather operation including daytime and rainy nights, with a Clauser-Horne-shimony-Holt S-parameter measured to be 2.41±0.14 and 2.49±0.06, respectively. Such a system shows unparalleled mobility, flexibility and reconfigurability compared to the existing satellite and fiber-based quantum communication, and reveals its potential to establish a multinode quantum network, with a scalable design using symmetrical lens diameter and single-mode-fiber coupling. All key technologies have been developed to pack quantum nodes into lightweight mobile platforms for local-area coverage, and arouse further technical improvements to establish wide-area quantum networks with high-altitude mobile communication.

作者： Peng Hongxia Li Chang’an shi Chaoyi Yang Chao Huang changsheng Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074 Faculty of Earth Sciences China University of GeosciencesWuhan 430074

Based on the data of organic carbon stable isotope ratios and magnet ic susceptibility, climate evolution in the past 5 kaB.P. in Poyang Lake plain (in Jiangxi Province) has been reconstructed. The results of the research indicate that the climate evolution can be divided into nine stages in the past 5 kaB.P.. Comparisons of different regional environmental records suggest that the intens ity and the temporal spatial changes of monsoon in China mainly controlled the climate evolution.

2017年11月18日,我国西藏林芝市米林县发生M6.9地震.其东南220km距离处,1950年发生了察隅8.6级大地震.二者同处喜马拉雅东构造结大拐弯处,周边分布多条活动断裂带.察隅地震作为20世纪我国内陆最大的地震,它的发生对周边断层活动性的影响目前研究尚少.本文基于分层半无限空间黏弹性地球模型,计算了察隅地震对周围活动断裂带和米林地震的影响,同时利用有限断层破裂模型计算了米林地震对周边活动断层产生的同震库仑应力变化,并分析了两次地震的关系,讨论了下地壳及以下介质的黏滞系数和断层有效摩擦系数对计算结果的影响.结果表明,察隅地震影响范围广、强度大且持续时间长,对喜马拉雅东构造结周边活动断层均产生了较大的影响,库仑应力变化达到数MPa量级.在下地壳黏滞系数为1.0×10^(20) Pa·s、摩擦系数为0.4情况下,按照青藏高原主要活动断裂每年由正常构造运动应力累积1~4kPa计算,察隅地震的发生使米林地震提前了相当于2.79~11.15年的时间.米林6.9级地震影响范围和强度有限,只对震源附近的活动断层产生一定影响,库仑应力变化最大为数十kPa量级,对远处的断层影响较小.下地壳及以下介质的黏滞系数在震后黏滞松弛过程中影响逐渐明显,断层有效摩擦系数对同震库仑应力计算影响较大.

本文基于中国大陆西部流动重力测量获得的区域重力场变化数据,尝试对其进行多种位场变换,在一定空间尺度约束下定义了6种区域重力场变化指标量.在此基础上,以中国大陆2002年、2005年和2008年等3期数据为研究对象,计算并统计了中国大陆西部MS≥6.0地震震中位置处震前重力场变化及各种导出参数值,尝试初步构建以地震预报为目的的地震重力学科指标体系参数.研究结果表明,震前区域重力场变化与地震发生位置没有显著的统计关系,但是重力场变化的垂直梯度和解析信号模量具有一定的地震预报意义,适合作为地震前兆异常使用.
