| 1 | Agricultural development and human diets in Gouwan site,Xichuan,Henan显示文摘This paper undertook the C and N stable isotopic analysis of human bones unearthed at the Gouwan site in Xichuan,Henan,to reveal the human diets and to explore the lifestyle of humans and the development of rice and millet agriculture.The contribution of rice to human diets was almost equal to that of millet in this site though millet agriculture is the traditional economic model for the middle Yellow River Valley.On the other hand,the comparison of C and N stable isotopes in different cultural periods clearly indicates changes in millet and rice agriculture.Humans mainly depended on agriculture and gathering in the Yangshao Culture I. Millet agriculture,livestock rearing,and fishing were enhanced in the Yangshao Culture II.Millet agriculture and animal husbandry developed steadily in the Yangshao Culture III.After that the mixed rice and millet agriculture developed further.In addition,rice agriculture spread to the north in the climate suitable for cultural exchanges between north and south in the Yangshao Culture phases.In the Qujialing Culture period,under a colder climate,the rice farming was not dominant,though the Qujialing Culture played a key role in the site. | FU QiaoMei JIN SongAn HU YaoWu MA Zhao PAN JianCai WANG ChangSui | 2010 | Chinese Science Bulletin2010，55，7： | 13 |
| 2 | Investigation of influence of coal properties on dense-phase pneumatic conveying at high pressure显示文摘Experiments of dense-phase pneumatic conveying of pulverized coal using nitrogen were carried out in a test facility at pressures of up to 3.7 MPa to study the effects of coal type, particle size and moisture content on flow characteristics. The Jenike shear test and scanning electron microscopy (SEM) were employed to provide a better understanding of effects of the material properties on flow characteristics. Two kinds of pulverized coals, Yanzhou and Datong, with similar particle size, moisture content and density, were used in the test. Pressure drop increases with increasing the particle size at similar solid-gas ratio, superficial velocity and pressure in the receiving hopper, and pressure drops through different test sections decrease firstly and then rise with increasing the conveying velocity for the same particle size, mass flow rate and pressure in the receiving hopper. The flowability of pulverized coal decreases with increasing the moisture content in the range from 3.24% to 8.18%. Unconfined yield strength (UYS) increases and flow function (FF) decreases with increasing the moisture content. Results of the shearing tests are consistent with the results of the conveying study. Pressure drops through different test sections are discussed and analyzed. | Cai Liang Xiaoxu Xie Pan Xu Xiaoping Chen Changsui Zhao Xin Wu | 2012 | Particuology2012，10，3： | 8 |
