雨水

Shanghai Poster Code: 201900 Abstract As the fresh water resource, rain water has been got high concerned.

随着新水用量的日益受限，钢铁企业逐步重视雨水的回收利用，实施雨水利用可在提高水资源综合利用的同时，降低用水成本，如何收集雨水成为首要的问题。

Rain on the birdhouse, Rain on the pond, Rain on the doghouse, But not on me.

雨水落在小鸟舍上，雨水落在池塘上，雨水落在狗舍上，但是没有落在我身上。

Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.

地形高度增加后，阻挡作用加强，使水汽通量辐合加强，垂直气流增大，中低层云水增多，导致雪撞冻过冷云水增多，促使了雨水撞冻雪转化为霰和霰干增长过程的加强，霰融化为雨水增多，低层雨水碰并云水加强，冷云过程得到增强。

Meanwhile, in this paper the patterns of rainwater utilization are designed. Collection system of rainwater is important , especially for the Green Belt of top garage.

同时对小区雨水利用方式进行了设计，认为雨水收集系统的设计非常重要，尤其是车库顶部绿化地带的雨水收集。

It is widely known that the shortage of water resource in northwestward region is very serious. So, how to resolve this problem is a important problem.

集雨技术倍受关注，其主要技术路线有两个，一是径流汇集，实现雨水的富集叠加利用；二是利用工程技术实现雨水的就地高效入渗，提高雨水的利用效率。

The experiment is began with the runoff quality on the diverse roofage and different grade roadway, the results are as follows:(1) The concentration of contamination is different with the diverse roofage, and SS value is also different with the style roof;(2) In the beginning , the concentration of COD value and SS value is higher ,but the runoff quality will be reduced to steady gradually along with the rainfall duration increase;(3) The city roadway runoff is worse than the roadway of university ,because the city roadway runoff involve vehicle n people and the sanitation and material of roadway;(4) Based on the analysis of rainwater quality , the paper provide the process of rainwater treatment for roof, roadway, and lawn.

对教学区内不同建筑物，及道路上的雨水径流水质进行监测，得出以下结论：(1)材料不同，径流雨水中污染物浓度不同，屋顶类型不同，径流雨水中SS浓度亦不同；(2)初期径流污染物浓度很高，随降雨历时的延长，COD和SS浓度逐渐下降并趋于稳定；(3)道路污染与路面材料、来往车辆、人员流动、路面卫生状况有关。市区道路相比校园内道路，水质较差；(4)对雨水水质分析基础上，分别对建筑屋顶、道路、绿地提出雨水利用的处理工艺。

The main factors affecting the filtration characteristics of perforated rainwater drainage pipe are studied by means of model test.

本文通过透水雨水管道模型试验，对渗透式雨水管道雨量入渗的主要影响因素进行了分析探讨，得到了判定管道开孔情况的临界面积公式，以及透水雨水管道在不同开孔条件下单位管长的雨水稳定渗透量计算公式。

Rain fell on the roof of the barn and dripped steadily from the eaves. Rain fell in the barnyard and ran in crooked courses down into the lane where thistles and pig weed grew. Rain spattered against Mrs. Zuckerman's kitchen windows and came gushing out of the downspouts . Rain fell on the backs of the sheep as they grazed in the meadow.

雨水落在谷仓顶上，不停的从屋檐上滴落下来；雨水落到谷仓院子里，弯弯曲曲地一道一道流进长着蓟草和藜草的小路；雨水噼噼啪啪地打在朱克曼太太的厨房窗上，咕咚咕咚地涌出水管；雨水落在正在草地上吃草的羊的背上。

In one corner was a stagnant pool of water, surrounding an island of muck; there were several half-drowned fowls crowded together under a cart, among which was a miserable, crest-fallen cock, drenched out of ail life and spirit; his drooping tail matted, as it were, into a single feather, along which the water trickled from his hack; near the cart was a half- dozing cow, chewing her cud, and standing patiently to be rained on, with wreaths of vapour(5) rising from her reeking hide; a wall-eyed(6) horse, tired of the loneliness of the stable, was poking his spectral head out of a window, with the rain dripping on it from the eaves; an unhappy cur, chained to a dog-house hard by, uttered something every now and then between a bark and a yelp; a drab of a kitchen wench(7) tramped backwards and forwards through the yard in pat- tens, looking as sulky as the weather itself; everything, iq short, was comfortless and forlorn, excepting a crew of hardened ducks, assembled like boon companions round a puddle and making a riotous noise over their liquor.

在院子的一角，一潭污水围着孤岛似的粪堆，几只几平被雨水淋透的鸡簇拥在一辆马车底下，其中一只可怜的公鸡，倒垂着鸡冠，被淋得没精打彩，毫无生气，它那耷拉着的尾巴粘结在一起，仿佛只成了一根羽毛，雨水顺着它从背脊往下直淌，高马车不远处。有一头睡跟惺忪的奶牛，嘴里嚼着反刍的食物，默默地站在那里，任凭雨水打在身上，湿淋琳的背上日出缭绕的水气；一匹眼珠小而眼白特大的马厌倦了马厩里的寂寞，把它那幽灵似的脑袋从窗口探了出来，屋檐上的雨水漓沥滴沥地落在它头上；一只不幸的杂种狗被链条拴在近旁的狗窝里，时时发出似吠似嗥的声音；一个邋遢厨娘拖着木屐，迈着沉重的步子在院子里进进出出，她那郁郁不乐的神色，就象阴沉的天气一样；总之，除了一群饱经风雨的鸭子，象饮酒作乐的朋友那样聚集在污水潭的四周呷呷嬉水而外，这儿的一切都令人感到凄凉的沮丧。
