编辑同志: 从贵刊出版的《中国给水排水》杂志1990年第二期上看到题为《公厕的节水冲洗装置》文章,受其启发设计一套比较简单的系统,用在相同条件下,其节水效果与文章中介绍的方法大致相同。
Editorial comrades: From the second issue of China Water Supply and Drainage magazine published in your magazine in 1990, I read the article titled “Water-saving flushing device for public toilets”. Inspired by it, I designed a relatively simple system to use under the same conditions. The water saving effect is almost the same as the method described in the article.
