3High-accuracy same-beam VLBI observations using Shanghai and Urumqi telescopes显示文摘The same-beam VLBI observations of Rstar and Vstar,which were two small satellites of Japanese lunar mission,SELENE,were successfully performed by using Shanghai and Urumqi 25-m telescopes. When the separation angle between Rstar and Vstar was less than 0.1 deg,the differential phase delay of the X-band signals between Rstar and Vstar on Shanghai-Urumqi baseline was obtained with a very small error of 0.15 mm rms,which was reduced by 1-2 order compared with the former VLBI results. When the separation angle was less than 0.56 deg,the differential phase delay of the S-band signals was also obtained with a very small error of several mm rms. The orbit determination for Rstar and Vstar was performed,and the accuracy was improved to a level of several meters by using VLBI and Doppler data. The high-accuracy same-beam differential VLBI technique is very useful in orbit determination for a spacecraft,and will be used in orbit determination for Mars missions of China Yinghuo-1 and Russia Phobos-grunt.KIKUCHI Fuyuhiko KAMATA Shun'ichi MATSUMOTO Koji HANADA Hideo 2009Science China(Physics,Mechanics & Astronomy)2009,52,12:11
4Improvement of corrosion resistance of AZ31 Mg alloy by anodizing with co-precipitation of cerium oxide显示文摘Anodizing of AZ31 Mg alloy in NaOH solution by co-precipitation of cerium oxide was investigated.The chemical composition and phase structure of the coating film were determined via optical microscopy,SEM and XRD.The corrosion properties of the anodic film were characterized by using potentiodynamic polarization curves in 17 mmol/L NaCl and 0.1 mol/L Na2SO4 solution at 298 K.The corrosion resistance of AZ31 magnesium alloy is significantly improved by adding cerium oxide to alkaline solution.In addition,the surface properties are enhanced and the film contains no crack.Salah Abdelghany SALMAN Ryo ichi ICHINO Masazumi OKIDO 2009中国有色金属学会会刊:英文版2009,19,4:6

6青藏高原唐古拉山南北坡夏季风降水特征的对比分析显示文摘根据 GAME- Tibet加强观测期间 ( 1 998年 5~ 9月 )所得到的位于青藏高原唐古拉山北坡的 D1 0 5站和南坡的 WADD站夏季风降水资料 ,对唐古拉山南北坡夏季风降水特征进行了初步的对比分析 .结果表明两地夏季风降水频率较高 .在 1 998年 6月 2 5日~ 9月 1 9日 ,WADD站的降水量比 D1 0 5站的降水量多 48.8% ,而发生的降水次数在 WADD站比 D1 0 5站多 1 0次 ,两者的累积降水次数基本上差不多 .同时 ,WADD站平均降水强度高于 D1 0 5站 .这两地的夏季风降水存在明显的活跃期和中断期 ,7月中旬夏季风降水都不活跃 .大多数情况下 ,这两地的日降水量的变化有较为一致的趋势 ,表明两地降水可能受同一降水过程的控制 .9月初以后 。杨梅学 姚檀栋 田立德 Ken'ichi UENO 2000应用气象学报2000,11,2:5
71998年夏季(7,8月)藏北降水的某些特征分析显示文摘利用GAME Tibet加强观测期间所得到的青藏高原不同地点的降水量资料 ,初步分析了 1 998年 7月和 8月夏降风降水随纬度和海拔高度的变化特征。研究表明藏北高原夏季风降水的分布是纬度效应和海拔高度效应综合作用的结果。 7月份降水量的纬度效应要比高度效应明显 ,而 8月份的降水量不但具有一定的纬度效应 ,也具有一定的海拔高度效应。 7月~ 8月份的降水量主要表现为随纬度的分布特征 ,但它也受到海拔高度效应的修正 ,即由于地形对降水的再分配过程 ,使得某些测点降水随海拔高度的升高而增加。由于青藏高原地表状况复杂 ,其上的降水显然应当同时受到各种因素的影响和制约 ,因此要简单地区分各因子的作用是较困难的。杨梅学 姚檀栋 Ken'ichi UENO 2000资源科学2000,22,6:5

16Last deglacial relative sea level variations in Antarctica derived from glacial isostatic adjustment modelling显示文摘We present relative sea level(RSL)curves in Antarctica derived from glacial isostatic adjustment(GIA)predictions based on the melting scenarios of the Antarctic ice sheet since the Last Glacial Maximum(LGM)given in previous works.Simultaneously,Holocene-age RSL observations obtained at the raised beaches along the coast of Antarctica are shown to be in agreement with the GIA predictions.The differences from previously published ice-loading models regarding the spatial distribution and total mass change of the melted ice are signifcant.These models were also derived from GIA modelling;the variations can be attributed to the lack of geological and geographical evidence regarding the history of crustal movement due to ice sheet evolution.Next,we summarise the previously published ice load models and demonstrate the RSL curves based on combinations of different ice and earth models.The RSL curves calculated by GIA models indicate that the model dependence of both the ice and earth models is signifcantly large at several sites where RSL observations were obtained.In particular,GIA predictions based on the thin lithospheric thickness show the spatial distributions that are dependent on the melted ice thickness at each sites.These characteristics result from the short-wavelength deformation of the Earth.However,our predictions strongly suggest that it is possible to fnd the average ice model despite the use of the different models of lithospheric thickness.By sea level and crustal movement observations,we can deduce the geometry of the post-LGM ice sheets in detail and remove the GIA contribution from the crustal deformation and gravity change observed by space geodetic techniques,such as GPS and GRACE,for the estimation of the Antarctic ice mass change associated with recent global warming.Jun’ichi Okuno Hideki Miura 2013Geoscience Frontiers2013,4,6:2
17Aerosol optical properties derived from simultaneous sunphotometer and aureolemeter measurements in Lhasa显示文摘In order to obtain some aerosol properties in Tibetan Plateau atmosphere, simultaneous measurements of aerosols by use of a sunphotometer and an aureolementer were performed in the summer of 1998 in Lhasa(29.65°N, 91.13°E). Optical depth, volume size distribution and phase\|function of aerosols were obtained from the measurements. Religious activities can have an effect on optical depth in Lhasa. The daily average aerosol optical depth( λ =500 nm) is less than 0.2. The diurnal variations of aerosol optical depth are relatively small during the period of summer. The maximal value of the mode radius in the volume size distribution are about 0.4, 2.0 and 4.0μm.BAI Yu\|bo\+1, SHI Guang\|yu\+\{1*\}, Koichi Tamura\+2, Takashi Shibata\+2, Yasunobu Iwasaka\+2, Kaneta Shin′ichi\+3, Takamura Tamio\+3 (1.
