As the crossroads of prehistoric cultures,the Beijing region is an important area for studying the exchange of prehistoric culture and the spread of millet *** millet remains have been found in the Donghulin site during the Early Neolithic Age,there is little millet remains during the Middle and Late Neolithic Age,so there is a gap of approximately2,000 years since the time of the Donghulin *** Shangzhai site is located in the Pinggu Basin in eastern Beijing,and it has a large time span with sequential strata;however,there are few large animals and plant remains found at this site,thus the subsistence strategy of ancient people remains *** this study,the absorbed lipids of pottery sherds unearthed in the Neolithic cultural layer of the Shangzhai site were extracted and *** results show that these potteries were used to process millet,the meat of terrestrial non-ruminants and wild ruminants,and dairy of wild ruminants,providing new insights for the subsistence strategy and the development of millet agriculture in the Middle and Late Neolithic Age of *** addition,the food processing in pottery may be an internal heating method,such as stone boiling.

Prehistoric groundstone tools including slabs (metate, mo-pan) and mullers (mano, mo-bang) are often considered to be tools that were used to process cereals in ancient China. Most archaeologists believe that groundstone tools are indicators of an agrarian economy. This study employed starch grain analysis to examine a slab and a muller excavated from the Shangzhai Site (7500-7000 cal a BP), Beijing. Identifiable starch grains recovered from the stone tools were classified into 9 genera and 12 species, most of which were from acorns and foxtail millets. Remains from the oak species Q. mongolicus, Q. acuttssima, and Q. dentate were identified as well as a few starch grains from broomcorn (Panicum miliaseum) and bean (Vigna sp.). Other starch grains were from unidentifiable roots and grasses. A variety of starch grains indicates that the grinding stone tools were used to process not only cereals, but also other seeds or roots that had to be ground or husked, thus bringing into question the aforementioned cereal hypothesis. Because the numbers of starch grains from nuts and millets were so large, both gathering and cultivation might have been important economic patterns before 7000 years ago in Beijing area. Moreover, the starch remains are derived from plants that indicate that the paleoclimate of Beijing was wetter and warmer than today’s.

The dynamic tensile properties and microstructural evolution of an extruded EW75 magnesium alloy deformed at ambient temperature and different high strain rates(from 1000 to 3000 s^(-1))along extrusion direction(ED)were investigated by Split Hopkinson Tension Bar(SHTB).The corresponding deformation mechanisms,texture evolution and microstructure changes were analyzed by optical microscope(OM),electron backscatter diffraction(EBSD)and transmission electron microscope(TEM).The results show that the extruded EW75 magnesium alloy along ED exhibits a conventional positive strain rate sensitivity that the dynamic flow stresses increase with in creasing strain *** measurements show that after dynamic tension,the initial weak texture of extruded EW75 magnesium alloy tansforms to a relatively strong//ED texture with increasing strain *** microstructural analysis demonstrates that dislocation motion are main deformatin mode to accommodate dynamic tensile deformation at high strain *** addition,the interactions of dislocation-dislocation and dislocation-second phase lead to the in crease of flow stress and strain hardening with increasing strain rate.

十月革命形成了影响深远的两大实践逻辑:一是革命逻辑,即当人民"毫无出路"时,布尔什维克党应该选择社会主义道路以帮助人民摆脱困境;二是建设逻辑,即"在工农政权和苏维埃制度基础上赶上别国人民"。苏联解体的重要原因在于忽视了上述建设逻辑内蕴的对社会主义政治权力本身的要求。中国改革体现了对十月革命两大实践逻辑的全面继承和发展。

科学社会主义的原创理论,是马克思运用唯物辩证法对人类一般历史过程和资本主义具体发展状况考察的结果;它们分别体现为以“两大发现”为基本内容的逻辑理论和以阶级斗争、无产阶级专政为基本内容的策略理论两个层次。历史上,社会主义运动一直恪守着马克思的逻辑理论,而根据实践条件的变化不断修正其策略理论。中国社会主义改革对市场经济体制的选择,从突破马克思的策略理论入手,逐渐超越了其逻辑理论的解释范围。中国社会主义者只有依据唯物辩证法重新考量时代条件,才有可能推动社会主义逻辑理论的相应发展。

马克思把"个人全面发展"视为共产主义社会的标志,并从两种视角予以阐释:从社会关系需要消灭阶级角度,将之作为消除分工岗位限制的前提;从自然关系趋向"自由个性"角度,将之作为劳动能力脑力化的结果。社会主义市场经济体制把两种思路融合在一起,通过政府作用促劣变优,展示了共享社会力资源的前景,创新了通向理想社会的道路。
