| 1 | 济州岛西南泥质区粒度组分变化的古环境应用显示文摘利用激光粒度仪对位于东海陆架济州岛西南泥质区的B2孔进行了沉积物粒度分析,根据标准偏差变化检出了B2孔含有4个粒度组分:>65.6、65.6~10.5、10.5~1.3和<1.3 μm,其中>65.6μm粗组分含量很低,主要是以底栖有孔虫为主的生源沉积.各组分平均粒径和粒度含量随孔深的变化显示了65.6~10.5μm组分在B2孔含量较高(21%~30%),变化最明显,是该孔对环境变化最敏感的粒度组分.研究表明该敏感组分的粒度含量和平均粒径变化主要受东亚冬季风的强弱变化制约,其变化恢复的近2 ka来东亚冬季风变化和中国东部气候变化序列具有很好的一致性,证明65.6~10.5 μm粒度组分可以作为东亚冬季风的替代指标. | 向荣 杨作升 郭志刚 Saito Y. 范德江 肖尚斌 陈木宏 | 2005 | 地球科学(中国地质大学学报)2005,30,5: | 31 |
| 2 | 冲绳海槽5万年以来的古气候事件显示文摘冲绳海槽DGKS9603孔岩芯δ18O曲线记录了50 kaBP以来的气候波动以及短尺度的古气候突变事件. 这些古气候事件可以与中国西北黄土、南海与北大西洋岩芯以及格陵兰冰芯记录的YD, H1, H2, H3, H4, H5事件对比. 古地磁分析的3个地球磁极倒转事件可分别与Gothenburg Mungo和Laschamp事件对应, 并大致可与H1, H3, H5事件对应, 这可能是造成全球气候变化的一个原因. 冲绳海槽岩芯δ18O曲线与李家塬黄土的粒度曲线有很好的对应关系, 与格陵兰冰芯记录的气候波动有某些差异, 表明还存在地域性的因素控制着两者的变化, 在东亚地区季风可能是一个主要的因素. | 刘振夏 李培英 李铁刚 黄奇瑜 程振波 韦刚健 刘乐军 李珍 S.

| 3 | Shifts of the Kuroshio axis over the last 20 000 years显示文摘Core 255 from the southern Okinawa Trough was selected to monitor the shift of the Kuroshio axis over the last 20 000 years. During the last glacial maximum the Kuroshio axis had ever shifted outside the Okinawa Trough. It entered the Okinawa Trough again at about 6 500 a BP, leading to abrupt increase of sedimentation rate, distinctly coarser sediment and remarkably increased abundance of foraminiferal indicators of the Kuroshio in the core. But, during about 4 000-3 000 a BP the abundance of the Kuroshio indicator Pulleniatina obliquiloculata sharply decreased again, indicating that the Kuroshio axis had ever shifted easterly for a short period or the Kuroshio was weakened and that moment. | Jian Zhimin Y.

| 4 | 冲绳海槽B-3GC钻孔柱状样花粉记录的古环境信息显示文摘根据冲绳海槽B-3GC钻孔柱状样芯花粉学记录, 探讨邻近岛屿9500 aBP以来环境变化. 研究表明, 多数时间以暖温带气候为主, 只有在全新世中期, 即6800-4400 aBP 曾受亚热带气候控制. 在9500- 8300和3100-2000 aBP时段, 气候相对变干、变冷. 周边陆地植被以常绿阔叶林和落叶阔叶林交替出现为主, 在高山地区有一定面积的针阔混交林分布. 多数情况下, 3种类型同时存在, 只是分布高度有所不同. 在6000-5000 aBP前后, 亚热带、热带的植物花粉成分大幅度增加, 反映植被带大幅度抬升, 常绿阔叶林面积扩大. 而在9500-8300和3000-2000 aBP 时段, 植被带有所下降, 常绿阔叶林面积缩小. 其他时段较现在略有上升, 但幅度有限. | 宋长青 孙湘君 Y.

| 5 | Modeling of numerical simulation and experimental verification for carburizing-nitriding quenching process显示文摘A model considering quantitative effects of diffused carbon and nitrogen gradients and kinetics of phase transformation is presented to examine metallo-thermo-mechanical behavior during carburized and nitrided quenching. Coupled simulation of diffusion, phase transformation and stress/strain provides the final distribution of carbon and nitrogen contents as well as residual stress and distortion. Effects of both transformation and lattice expansion induced by carbon and nitrogen absorption were introduced into calculating the evolution of the internal stress and strain. In order to verify the method and the results, the simulated distributions of carbon and nitrogen content and residual stress/strain of a ring model during carburized and nitrided quenching were compared with the measured data. | R.

| 6 | A broad deglacial δ^(13)C minimum event in planktonic foraminiferal records in the Okinawa Trough显示文摘The equatorial Pacific upwelling zone has been suspected of playing an important role in the global atmospheric CO2 changes associated with glacial-interglacial cycles. In order to assess the influencing scope of the surface water deglacial δ13C minimum in the tropical low-latitude Pacific, the core DGKS9603, collected from the middle Okinawa Trough, was examined for δ13C records of planktonic fo-raminifera N. dutertrei and G. ruber. The planktonic fo-raminiferal δ13C records show a clear decreasing event from 20 to 6 cal. kaBP., which is characterized by long duration of about 14 ka and amplitude shift of 0.4×10-3. Its minimum value occurred at 15.7 cal kaBP. The event shows fairly synchrony with the surface water deglacial δ13C minimum identified in the tropical Pacific and its marginal seas. Because there is no evidence in planktonic foraminiferal fauna and δ18O records for upwelling and river runoff enhancement, the broad deglacial δ13C minimum event in planktonic foraminiferal records | LI Tiegang, LIU Zhenxia, M.

| 8 | ICRF Heated Long-Pulse Plasma Discharges in LHD显示文摘A long-pulse plasma discharge for more than 30 min.was achieved on the LargeHelical Device(LHD).A plasma of n_e=0.8×10^(19)m^(-3)and T_(iO)=2.0 keV was sustained withP_(ICH)=0.52 MW,P_(ECH)=0.1 MW and averaged P_(NBI)=0.067 MW.Total injected heatingenergy was 1.3 GJ,which was a quarter of the prepared RF heating energy.One of the keys to thesuccess of the experiment was a dispersion of the local plasma heat load to divertors,accomplishedby shifting the magnetic axis inward and outward. | R.

| 15 | Deformation mechanism at impact test of Al-11% Si alloy processed by equal-channel angular pressing with rotary die显示文摘Al-11%Si(mass fraction)alloy was transformed into a ductile material by equal-channel angular pressing(ECAP)with a rotary die.Two mechanisms at impact test,slip deformation by dislocation motion and grain boundary sliding,were discussed.The ultrafine grains with modified grain boundaries and the high content of fine particles(<1μm)were necessary for attaining high absorbed energy.The results contradict the condition of slip deformation by dislocation motion and coincide with that of grain boundary sliding.Many fine zigzag lines like a mosaic were observed on the side surface of the tested specimens.These observed lines may show grain boundaries appeared by the sliding of grains. | 马爱斌 Y.

| 18 | Effect of microstructures on superplasticity of Al-11%Si alloy显示文摘Three kinds of Al-11%Si (mass fraction) alloy samples with different processes were produced to investigate the effect of microstructures on its superplasticity. Among them, the as-ECAP sample pressed 16 passes has ultrafine grains (300 nm) and the finest secondary particles. The ECAP-T6 sample, with ECAP 16 passes followed by T6 treatment, has fine secondary particles (3 μm) but the largest grains (8 μm). Contrarily, the T6-ECAP sample, with T6 treatment followed by ECAP 16 passes, has ultrafine grains and the large secondary particles (7 μm). The tensile testing results show that the as-ECAP sample exhibits superplasticity at high strain rate of 5.75×10-1 s-1 due to its fine secondary particles and ultrafine grains. The ECAP-T6 sample, however, does not exhibit superplasticity at the same high strain rate of 5.75×10-1 s-1 because it has relatively large secondary particles and large grains. Remarkably, the T6-ECAP sample does not have superplasticity even at the lower strain rate of 1.15×10-1 s-1, attributing to its comparatively large secondary particles. When most secondary particles are larger than 7 μm, the high strain rate superplasticity could not be obtained even if this sample has ultrafine grains. | 江静华 马爱斌 N. SAITO A. WATAZU 林萍华 Y.

| 20 | Corrosion behavior of hypereutectic Al-23%Si alloy (AC9A) processed by severe plastic deformation显示文摘Ultrafine-grained(UFG) hypereutectic Al-23%Si (mass fraction) alloy was achieved through equal-channel angular pressing(EACP) procedure. And the electrochemical properties after various ECAP passes were investigated in neutral NaCl solution. Potentiostatic polarization curves show that the corrosion potential of the ECAPed sample after 4 passes decreases markedly, while the corrosion current density reaches 1.37 times that of the as-cast alloy. However, the φcorr and Jcorr values after 16 passes are improved and approach those of the as-cast alloy. Immersion tests also show that the mass-loss ratio of ECAPed alloy decreases with increasing the pressing pass, which is lowered to 28.7% with the increase of pass number from 4 to 16. Pitting susceptibility of the ECAPed alloy after initial 4 passes is boosted, due to the presence of biggish voids resulted from the breakage of brittle large primary silicon crystals during ECAP. Increasing ECAP pass makes the voids evanesce and results in the homogeneous ultrafine-grained structure, contributing to a higher pitting resistance. These results indicate that enough ECAP passes are beneficial to increasing corrosion resistance of the hypereutectic Al-23%Si alloy. | 江静华 马爱斌 宋丹 N. SAITO 袁玉春 Y.
