2) low carbon city
低碳城市
1.
China is facing domestic and international pressure of carbon emission reduction, and since the diversity and imbalance of the regional development, a national greenhouse gas (GHG) abatement is unpractical, while we believe that a low carbon city strategy is the key to such a deadlock.
地区化的低碳发展及低碳城市建设,成为打破这一困境的关键。

Based on this,test was made on low carbon source urban wastewater treatment in Guangzhou region by using SBR process to investigate the effect and affecting factors of biological phosphorus removal.
碳、氮、磷比例失调(碳量偏低)城市污水的脱氮除磷一直是个难题,为此采用SBR法处理广州地区低碳城市污水,研究了生物除磷效果及其影响因素。
补充资料：超低碳不锈钢
分子式：
CAS号：
性质：含碳量低于0.03％的不锈钢，一般指奥氏体不锈钢。不锈钢中的碳含量降低到0.03％以下，即超低碳化，能有效地避免不锈钢出现贫铬区和防止晶间腐蚀敏感性。碳在铁素体不锈钢中的危害更加严重，当大约从927℃；以上快冷时就会沿晶界析出铬的碳化物，形成晶界贫铬区，而在腐蚀环境中容易发生晶间腐蚀，为了避免晶间腐蚀就要求碳含量必须低于0.01％。采用氩氧脱碳精炼法和真空氧脱碳精炼法，都能生产超低碳不锈钢。
