| 1 | EXPERIMENTAL STUDY ON INCIPIENT MOTION OF SEDIMENT PARTICLES ON GENERALIZED SLOPING FLUVIAL BEDS显示文摘This paper presents an experimental investigation on incipient motion of non-cohesive uniform sediment under a steady-uniform stream flow on generalized sloping fluvial beds (combined lateral and stream-wise slope). The characteristic parameters affecting the incipient motion of sediment particles, identified based on the physical reasoning and dimensional analysis, are the threshold shear stress ratio (ratio of threshold shear stress for sloping bed to that for horizontal bed), lateral slope, stream-wise slope and angle of repose of sediment particles. Experiments were carried out in two ducts (closed-conduit flow) having section of semicircular invert with three types of sediments. In an open channel flow (laboratory flume study), the uniform flow is a difficult, if not impossible, proposition for a steeply sloping channel and is impossible to obtain in an adversely sloping channel. To avoid this problem, the tests were conducted with a closed-conduit flow. Equation of critical bed shear stress for the initial movement of sediment particles on generalized sloping beds was obtained using the experimental data. | Subhasish DEY Asst.

1.社区组织行政化、机关化倾向严重。由企业剥离出来的社会职能需要街道社区承接.党和政府的社会管理和公共服务也要经过街道社区组织落实.致使社区组织行政化、机关化的倾向严重。区街两级政府对社区工作干预过多,下派任务过多.造成社区组织忙于应付上级交派的任务,没有精力抓好社区建设.其自治功能也趋于弱化。 | 中共天津市委党校第91期进修一班'民计民生与社会建设'课题组 | 2014 | 求知2014,,3: | 0 |

| 19 | OBSERVATION OF 14 CASES OF LARYNGEAL CARBUNCLE TREATED BY WEI JIA'S BLOOD-LETTING THERAPY显示文摘The author used the pricking-blood therapy to treat 14 cases of laryngeal car-buncle.The pricking-blood therapy included clumpy pricking(local area),spot pricking(prickingSanshang points on the thumb and three points of the helix).The therapy has role of clearing awaypathogentic heat and toxic materials and promoting subsidence of swelling.It could avoid forming py-opoiesis and free from operating treatment.The treatment was given once daily,result:13 cases cured(93%),1 case failed(7%).In 14 cases,antero-upper type has 13 cases which cured,postero-uppertype has only 1 case which treated failure.It is because its imflammation was located on posterior totonsillae,exposed bad and pricked difficulty.So the therapy only used antero-upper type of laryngealcarbuncle and had a good effect. | Xie Qiang Jiangxi Provincial TCM Hospital of Jiangxi College of Traditional Chinese Medicine,Nanchang 330006,ChinaZhang Qiaobao Guanghua Plastic Factory of Jiangxi,Nanchang,ChinaGuo Hongying 91 post-graduated student of Jiangxi College of T.C.M,Nangchang,China | 1993 | World Journal of Acupuncture-Moxibustion1993,3,2: | 0 |
