陶诗主题的创新袁行霈在东晋和(南朝)宋之间,诗歌艺术有一个重大的转折,陶渊明和谢灵运两人的诗歌分别属于前后两个时期。陶渊明沿袭魏晋诗歌的古朴作风,可以说是魏晋诗歌的集大成者;谢灵运开出追求声色的一条新路,而成为南朝诗歌的开创者。就陶诗的语言艺术而言,...

本文对新型颗粒弥散铝基纳米晶薄带的微观结构、相转变和力学性能作了详细研究.结果表明,随着混合稀土(Mm)含量的增加,快凝al-Fe-V-Si合金α-al晶粒和弥散颗粒不断细化,形成颗粒弥散铝基纳米晶材料.稀土元素在快凝过程中促使亚稳相al8Fe4Mm的形成,抑制α-al13(Fe,V)3Si相的析出.含0.5%和1.0%Mm(原子分数)纳米合金在673K附近al8Fe4Mm转变为α-al13(Fe,V)3Si相.含1%Mm快凝合金形成很细的颗粒弥散纳米晶材料,其断裂强度和疲劳强度比微晶al-Fe-V-Si合金高出1倍,且具有更好的热稳定性.

<正> 世界的末日 据来自纽约的消息,已连续11年身披国际象棋世界冠军金甲的加里·卡斯帕罗夫(Garry Kasparov),将于1997年5月再度向IBM并行计算机“深蓝”(Deep Blue)发起挑战。IBM公司为此项赛事特设110万美元奖金,胜者将获70万美元。《纽约时报》说,不论是输是赢,“深蓝”挣得的钱都将注入进一步的研究中。“深蓝”或许会用这些钱为自己添置新的芯片吧。

The civilization of the Yellow River valley was developed on the basis of millet-farming agriculture. The society in this area began to break up and went to civilization at about 3500 B. C. From 3000B. C.to 2100B. C. of the Longshan Times,many walled towns or cities emerged and thus the dawn of ancient Chinese civilization came into being. The following Erlitou Culture may have been the culture of the Xia people during the Xia Dynasty. The Xia State became the largest one among states in the Yellow River valley after Shaokang's rejuvenation. The Shang and Zhou expanded their forces into the Yangtze River valley and the Yanshan Mountain and the Liaohe River valley. Once ancient Chinese civilization reached its prosperity, the central place of the Yellow River valley established.

Liu PSK, Leaitch WR, Banic CM, Li SM, Ngo D, Megaw WJ. Aerosol observations at Chebogue Point during the 1993 North Atlantic Regional Experiment: Relationships among cloud condensation nuclei, size distribution, and chemistry. JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES. 1996;101:28971-28990.Abstract
Observations of aerosol chemistry and microphysics were made at Chebogue Point, Nova Scotia, from August 16 to September 8, 1993 as part of the North Atlantic Regional Experiment (NAPE) intensive. Most of the aerosols were classified into two groups according to the geometric mean volume diameter (D-gv) of the particles which contributed the greatest volume (sub-0.5 mu m) The group-1 aerosols; representing 33% of the data, are characterized by D-gv of 0.18-0.19 mu m; the group-2 aerosols, representing 50% of the data, are characterized by D-gv of 0.20-0.22 mu m; and the remaining aerosols bear similarities to either groups 1 or 2 but lie outside the D-gv ranges. The differences between these aerosol groups are consistent with the addition of sulfate to the group-2 aerosols via recent processing through cloud. Factors supporting this possibility include the presence of low marine stratus upwind of the site only on days when the group-2 aerosol was observed, the higher D-gv for the group-2 aerosols consistent with the observed size threshold for activation in these clouds, and the association of non-sea-salt SO4= (nssSO(4)(=)) with larger particle sizes for the group-2 aerosols. In general, the masses of the most abundant inorganic and organic ions, nssSO(4)(=) and oxalate, were associated with the main volume of the sub-0.5-mu m particles. Cloud condensation nucleus (CCN) concentrations active at 0.4% supersaturation (CCN0.4) were highly correlated with the concentrations of particles >0.01 mu m and oxalate and moderately correlated with nssSO(4)(=). Concentrations of CCN active at 0.06% supersaturation (CCN0.6) correlate very well with the concentrations of particles >0.19 mu m diameter. In the case of the recently cloud-processed aerosols, for which nssSO(4)(=) is more strongly associated with particles >0.19 mu m, the CCN0.06 also correlate well with nssSO(4)(=) CCN spectra computed using the measured size distributions and aerosol chemistry agree well with the measured CCN.
