  • Stylistic Analysis on Online News Story Comments

    This study examines stylistic features of the news story comments from major online news outlets and their possible ef-fects on the evolution of the English language. With a corpus composed of 34 examples drawn from renowned news sites such as The Washington Post, The Economist, Wall Street Journal, CNN and NBC, a detailed analysis on the stylistic features and effects of the news story comments has been conducted for the purpose of discovering possible links between a poster ’s linguistic behav-ior and his thought process. The result shows that interrogative, noun phrase and verb phrase are commonly used in news story comments by virtue of their slightly ostentatious nature. Rhetorical devices such as metaphor, simile and parataxis are frequently employed among comments. And the relationship between a poster’s educational background and his postings is also touched up-on at the end of this study....

  • RILL EROSION PROCESS AND RILL FLOW HYDRAULIC PARAMETERS

    In the rill erosion process,run-on water and sediment from upslope areas,and rill flow hydraulic parameters have significant effects on sediment detachment and transport.However,there is a lack of data to quantify the effects of run-on water and sediment and rill flow hydraulic parameters on rill erosion process at steep hillslopes,especially in the Loess Plateau of China.A dual-box system,consisting of a 2-m-long feeder box and a 5-m-long test box with 26.8% slope gradient was used to quantify the effects of upslope runoff and sediment,and of rill flow hydraulic parameters on the rill erosion process.The results showed that detachment-transport was dominated in rill erosion processes; upslope runoff always caused the net rill detachment at the downslope rill flow channel,and the net rill detachment caused by upslope runoff increased with a decrease of runoff sediment concentration from the feeder box or an increase of rainfall intensity.Upslope runoff discharging into the rill flow channel or an increase of rainfall intensity caused the rill flow to shift from a stratum flow into a turbulent flow.Upslope runoff had an important effect on rill flow hydraulic parameters,such as rill flow velocity,hydraulic radius,Reynolds number,Froude number and the Darcy-Weisbach resistance coefficient.The net rill detachment caused by upslope runoff increased as the relative increments of rill flow velocity,Reynolds number and Froude number caused by upslope runoff increased.In contrast,the net rill detachment decreased with an increase of the relative decrement of the Darcy-Weisbach resistance coefficient caused by upslope runoff.These findings will help to improve the understanding of the effects of run-on water and sediment on the erosion process and to find control strategies to minimize the impact of run-on water....

  • Gas and pressure effects on the synthesis of amorphous carbon nanotubes

    The effects of gas, pressure and temperature on the production of amorphous carbon nanotubes were investigated using an arc discharging furnace at controlled temperature. Co/Ni alloy powder was used as catalyst.The discharge current was 80 A and voltage was 32 V. The optimal parameters were obtained: 600℃ temperature, hydrogen gas and 500 torr pressure. The productivity and purity of amorphous carbon nanotubes are 6.5 gram per hour and 80%, respectively. The diameter of the amorphous carbon nanotubes is about 7-20 nm....

  • Physical modelling and scale effects of air-water flows on stepped spillways

    During the last three decades, the introduction of new construction materials (e.g. RCC (Roller Compacted Concrete),strengthened gabions) has increased the interest for stepped channels and spillways. However stepped chute hydraulics is not simple, because of different flow regimes and importantly because of very-strong interactions between entrained air and turbulence. In this study, new air-water flow measurements were conducted in two large-size stepped chute facilities with two step heights in each facility to study experimental distortion caused by scale effects and the soundness of result extrapolation to prototypes. Experimental data included distributions of air concentration, air-water flow velocity, bubble frequency, bubble chord length and air-water flow turbulence intensity. For a Froude similitude, the results implied that scale effects were observed in both facilities, although the geometric scaling ratio was only Lr=2 in each case. The selection of the criterion for scale effects is a critical issue. For example, major differences (i.e. scale effects) were observed in terms of bubble chord sizes and turbulence levels although little scale effects were seen in terms of void fraction and velocity distributions. Overall the findings emphasize that physical modelling of stepped chutes based upon a Froude similitude is more sensitive to scale effects than classical smooth-invert chute studies, and this is consistent with basic dimensional analysis developed herein....

  • 煤与渣油共热解对焦油及热解气品质的影响

    基于煤热解焦油产率低、品质差以及渣油如何高效利用问题,在固定床上进行了淮南煤、准格尔煤与渣油的共热解实验.结果表明:在煤中添加渣油可提高焦油产率,且共热解对焦油产率有协同作用.焦油中正己烷可溶物及脂肪族比例提高,品质显著改善.随着渣油添加比例的增加,热解气中CO、CO2比例降低,C1-C4(C1,C2,C3,C4总和)在热解气中体积比例增加;且C1-C4中CH4比例降低,C2,C3,C4比例升高,说明共热解过程渣油有供氢作用,使得焦油产率增加且品质提高....
