| 1 | 全球定位系统数据所显示的华北平原现今形变显示文摘华北平原是一个地震危险性很高的地区,但先前的全球定位系统测量显示,华北平原现今几乎没有地壳形变。利用中国东部三个块体的最新全球定位系统数据,发现华北平原的地震间形变发生在一个近东西向、宽约1100km的左旋剪切带内。地震间的左旋剪切形变为6.0±1.3mm/a,其造成的现今形变最终被沿北—北东向断层、右旋走滑的地震破裂和块体的逆时针旋转所调节。我们认为刚性华南块体相对于刚性阿穆里安块体向东的快速运动,产生了一对左旋剪切力偶,扭曲了非刚性的华北平原,形成了现今的地壳形变。 | Y.G.Zhang W.J.Zheng Y.J.Wang D.L.Zhang Y.T.Tian M.Wang Z.Q.Zhang P.Z.Zhang 李莹甄(译) 颜梓幸(译) 赵爱华(校) | 2020 | 世界地震译丛2020，51，1： | 1 |
| 2 | Accelerated protons with energies up to 70 MeV based on the optimized SG-Ⅱ Peta-watt laser facility显示文摘The target backsheath field acceleration mechanism is one of the main mechanisms of laser-driven proton acceleration(LDPA)and strongly depends on the comprehensive performance of the ultrashort ultra-intense lasers used as the driving sources.The successful use of the SG-II Peta-watt(SG-II PW)laser facility for LDPA and its applications in radiographic diagnoses have been manifested by the good performance of the SG-II PW facility.Recently,the SG-II PW laser facility has undergone extensive maintenance and a comprehensive technical upgrade in terms of the seed source,laser contrast and terminal focus.LDPA experiments were performed using the maintained SG-II PW laser beam,and the highest cutoff energy of the proton beam was obviously increased.Accordingly,a double-film target structure was used,and the maximum cutoff energy of the proton beam was up to 70 MeV.These results demonstrate that the comprehensive performance of the SG-II PW laser facility was improved significantly. | H.H.An W.Wang J.Xiong C.Wang X.Pan X.P.Ouyang S.Jiang Z.Y.Xie P.P.Wang Y.L.Yao N.Hua Y.Wang Z.C.Jiang Q.Xiao F.C.Ding Y.T.Wan X.Liu R.R.Wang Z.H.Fang P.Q.Yang Y.E.Jiang P.Z.Zhang B.Q.Zhu J.R.Sun B.Qiao A.L.Lei J.Q.Zhu | 2023 | High Power Laser Science and Engineering2023，11，5： | 0 |
