记得儿时不“开窍”,“比和比例”、难得要领.幸得教师为我开“小灶”、作启蒙,遂迎“窍”而解令人意想不到的是,儿时的“困惑”今又重现——虽非为做题犯难,却同因“反比”困惑.按说,市政消火栓的设置和数量,与城镇发展规模本名是一种正比例关系.然而,笔者近来跑了几个城、镇,所了解的情况却是,高楼大厦拔地而起,城镇建设规模日新月异;市政消火栓的可使用数却越来越少,形成一种实实在在的“反比”.这,岂不叫人困惑!某县城房屋开发区,约2平方公里的建筑群,竟没有安装1个消火栓.经查看原始总体规规划图,其消火栓布局却完全“合格”.另有一个县城,8年前共有市政消火栓时14个,而今整个县城几乎扩大了一倍,消火
I remember childhood not “resuscitation”, “ratio and proportion”, rare essentials fortunate enough for my teacher to open a “small cook” for enlightenment, then welcome “awake” solution is surprising is that childhood “puzzled” today It is said that the setting and quantity of municipal fire hydrants is directly proportional to the name of the scale of urban development.However, I recently ran several cities, What we know about the town is that the high-rise buildings are rising rapidly, and the scale of urban construction is changing rapidly. However, the number of usable municipal fire hydrants is getting smaller and smaller, forming a real “inverse ratio.” Perplexed! A county town housing development zone, about 2 square kilometers of buildings, did not install a fire hydrant.After looking at the original master plan, its fire hydrant layout is completely “qualified.” Another county, 8 years ago, a total of municipal Hydrant 14, and now the entire county almost doubled, fire
