| 1. | Employers are advised not to require their employees to go to work unless prior agreement on work arrangements during rainstorms has been made 政府呼吁雇主不应要求雇员上班,除非有关暴雨时的工作安排已有事先协定。 |
| 2. | As a result , a portion of the dirty water is eventually released into rivers or the sea via storm water spillways or pumping stations 然而,这种方式在暴雨时会导致一部分被稀释的污水经过泄洪口或抽水站,注入到河流或海洋。 |
| 3. | Roofs must be given sufficient fall to drain water off quickly and adequate gutters formed in the concrete to discharge the water in heavy storm 屋顶必须有足够的坡度,以利迅速排水,同时混凝土屋面板必须有足够的雨水槽,以利暴雨时排水。 |
| 4. | The heavy - hard rain in northeast qinghai - xizang plateau is that precipitation in 24h 25 . 0 mm . the regional one is that there are three stations whose precipitation in 24h 25 论文中高原地区的大到暴雨是指24h降水量25 . 0mm的降水,若同日有3个或3个以上站点出现大到暴雨时则称为1次区域性大到暴雨。 |
| 5. | It concluded 56 that ferrisols aggregate breakdown was caused by the pressure produced by the entrapped air in the soil porosity when fast wetting , which indicated that ferrisols erosion was most severe in the sudden heavy rain in the nature 富铁土团聚体的崩解主要是由土壤快速湿润时,挤压孔隙内的闭塞空气而产生的压力,说明富铁土土壤在突降暴雨时侵蚀最严重。 |
| 6. | Using the mm5 model to conduct investigation of numerical simulation for this case , it was basically possessed of a capability to reproduce the genesis , development and evolution of the large - scale and mesoscale weather systems 本文以mm5模式模拟分析“雅安天漏”为代表,着重研究了不同边界层参数化方案对雨量中心强度、雨区分布的影响以及雅安暴雨时的纬向垂直环流结构。 |
| 7. | Special analysis is made to see the impact of different boundary layer parameterization schemes on some factors which affect the heavy rainfall such as vertical velocity , divergence , vorticity , divergence of water vapor flux , se field and so on 结果表明:复杂地形条件下,特别是降水有明显日变化的地区,边界层的作用是十分重要的,这在暴雨时的纬向垂直环流结构中表现地非常明显。 |
| 8. | Therefore , if urban rainwater can be utilized to recharge groundwater , it not only can supply decreasing groundwater resource and prevent ground sedimentation a nd elevate groundwater level , but also can reduce expense of function and investment to drainpipe in city and lessen flood and waterlogging disaster at rainstorm 因此,若能利用城市汇集的雨水回灌地下不仅可以补充日益匮乏的地下水资源、阻止或减缓地面下沉、提高地下水位,同时还可以通过分流部分雨水减少城市排水管道和泵站的投资以及运行费用,并可减轻暴雨时洪涝灾害的发生。 |
| 9. | They make sure the definite of the necw , the spread of the necw , the start time of the necw . above all , the study of the meso - scale system gives much help in analysis the necw . mr . shou shaowen studied the wet whorl q - vector divergence and relative whorl " in several rainstorms , which occurred in guizhou , and get some useful conclusions 本文从一次东北冷涡的发生发展过程出发,利用9210系统广播的实况数据及t213数值预报的再分析产品,研究讨论了特定冷涡形势下辽西地区暴雨的发生机制,对其产生暴雨时的相关物理量及诊断量进行了分析。 |
| 10. | Using a " vortex intake " device , the underground drainage system has the dual benefit of relieving storm flow in downstream urban areas in districts such as western and kennedy town , and avoiding the difficulty of constructing or enlarging drains and culverts in urban areas and the resultant disruption to traffic that may ensue . the " vortex intake " project is a significant piece of hku s research achievements , and exemplifies the collaboration between academia , industry and government 漩涡进水口的水力工程,不单可以纾缓西区及坚尼地城一带于暴雨时,因大量急湍的水流往下冲而造成水浸及危险的问题,还避免了在市区兴建或扩建排水道及暗渠的工程;在闹市中进行此类工程十分困难及费时,并且一定会阻碍交通,带来不便。 |
