This study modeled the effects of structural and dimensional manipulations on hydrodynamic behavior of a bench vertical current classifier. Computational fluid dynamics （CFD） approach was used as modeling method, and turbulent intensity and fluid velocity were applied as system responses to predict the over- flow cut size variations. These investigations showed that cut size would decrease by increasing diameter and height of the separation column and cone section depth, due to the decrease of turbulent intensity and fluid velocity. As the size of discharge gate increases, the overflow cut-size would decrease due to freely fluid stream out of the column. The overflow cut-size was significantly increased in downward fed classifier compared to that fed by upward fluid stream. In addition, reforming the shape of angular overflow outlet＇s weir into the curved form prevented stream inside returning and consequently unselec- tire cut-size decreasing.

This paper describes the results obtained from two year experiment conducted at farmer’s field in Bulandshahr Delhi,India aimed at understanding the effect of different establishment methods on rice production during 2006 and 2007 using an aromatic rice variety,Pusa Sugandh *** this experiment,the treatment consisted four planting techniques and three irrigation treatments were *** four different establishment methods were transplanted rice on puddled(TPR),direct wet seeded(DWS),direct dry seeded on flat bed (DDS)and transplanting slope of ridges in a furrow- ridger configuration(FTP).In all establishment methods,the three irrigation regimes exposed were continuously submerged (W),irrigation after 1 day drainage(W),and irrigation after 3 days drainage(W). Averaged over irrigation regimes,among all the treatments,TPR had the highest grain yield followed by FTP,and DWS which were 4773,4379 and 4229 kg ha,*** lowest grain yield was obtained in DDS. The use of irrigation water input in non puddled treatment was significantly reduced. The total amount of water applied in DDS and FTP for similar irrigation treatment(W)was 1044 and 977 mm,*** to TPR,the reduction of total water input was 38 and 42%in DDS and FTP respectively,for similar irrigation treatment(W),and comparing to flooded direct wet seeded(DWS)it was 29 and 34%.Water productivity(WP)ranged from 0.60 to 0.86 g grain kgwater under W irrigation treatment which was highest in FTP. In terms of(WP),averaged across irrigation treatments,FTP also had the highest value (0.498 g grain kgwater)followed by DDS(0.421 g grain kgwater). Economical evaluation showed that the total cost of production of one hectare has been reduced by 13 percent in FTP compared to *** addition to those intangible benefits such as working condition has been improved *** of different rice establishment methods showed that cost/benefit ratio was highest in case of FTP due to relatively

由于温度疲劳现象引起的裂缝会导致沥青混凝土路面结构性能和使用质量的严重下降。温度疲劳裂缝发生在气候温和的地区,是受约束的铺装层内部温度循环应变/应力的结果。该文介绍一种在恒定应变荷载作用下测量沥青混凝土试样抗温度疲劳的试验装置。为了模拟沥青混凝土的温度疲劳行为,采用机械方法对沥青混凝土进行单轴加载,在0.01 Hz的频率下实现恒幅正弦应变。试验结果表明:沥青含量、集料来源和沥青结合料等级对沥青混凝土的抗温度疲劳性能影响最大。
