But cities are the human nest- they are where most of us live. They could reflect the values of life-enhancing, health-giving cultures. If cities are central to the problem of the ecological crisis they must be central to its solution. In the last few years a worldwide movement has developed which seeks to create ecological cities, cities in balance with nature.
但城市是人类的巢-是我们大多数人生活的地方。城市能反映出生命的价值-不断提升、有益健康的文化。如果说城市是生态危机问题的症结所在，那城市也必然是解决这一问题的关键所在。过去几年进行了一场创建生态城市、城市与自然协调发展的世界范围的运动。

纳氏试剂光度法测定氨氮影响因素的探讨
摘要：氨氮以游离氨或铵盐形式存在于水中。测定氨氮的方法通常有纳氏比色法、气相分子吸收法、电极法等。纳氏试剂比色法有操作简便、灵敏等特点。本文提出用纳氏试剂光度法测定氨氮的常见问题及解决方法。
Pay reagent luminosity follows the investigation and discussion abstract determining ammonia nitrogen influencing factor: The ammonia nitrogen there exists Yu Shui Zhong in form with free ammonia or ammonium salt. The method determining the ammonia nitrogen has generally pay than color law, the gas appearance molecule absorb law, electrode law etc. Mrs.Pay reagent handle characteristics such as simple and convenient, keen than color law has. The main body of a book is accepted bringing forward use reagent luminosity follows common problem and solution determining the ammonia nitrogen.
