摘　　要：为了探讨温度对黏液形成菌污垢特性的影响,对不同入口温度和不同水浴温度条件下黏液形成菌在不锈钢光管中的污垢特性进行了实验研究。结果表明:随着入口和水浴温度的升高,诱导期时间缩短,污垢热阻达到渐近值所需时间减少。在实验温度范围内,入口温度为30℃时污垢热阻渐近值最大,35℃时次之,25℃时最小。所以,污垢热阻渐近值随着水浴温度的升高而减小。In order to study on the effect of temperature on fouling characteristics of slime-forming bacteria,the slime-forming bacteria fouling characteristics in stainless steel tube heat exchanger was experimentally studied by changing the inlet temperature and water bath temperature. The results show that,induction period and the time to stabilization both reduce with the increasing of inlet and water bath temperature. The asymptotic value of fouling resistance is maximum at 30 ℃ in the experimental temperature range,then following at 35 ℃,and minimum at 25 ℃. With the increasing of water bath temperature,fouling resistance asymptotic value decreases.
