| 中文摘要 |
| 通过对梭幼鱼各项温度基准值的测定,研究了电厂冷却水对梭幼鱼的热效应。结果表明,自然水温25℃条件下,校幼鱼的回避温度、TL50、UILT、MWAT、CTM、短期暴露最高温度分别为34℃、36.7℃、38.75℃、30.52℃、40.82℃、35.32℃;建立了校幼鱼对温度效应的敏感区域图和温度一时间方程logt(min)=17.9422+0.4202T(℃)及安全受热方程T(℃)=(log1440—α)/b—2;初步得出ΔT=15℃高温冲击2min,梭幼鱼死亡率为25%,ΔT=14℃高温冲击5min为15%,可忍受最大ΔT不超过15℃。 |

| The title study was carried out by measuring various critical temperatures for young mullet. The results show that under the condition of a natural water temperature of 25℃,young mullet had its acvoidance temperature,TL50 UILT,MWAT,CTM and short-term exposure maximum temperature of ,34℃,36.7℃,38.75℃,30.52℃,40.82℃ and 35.32℃,respectively. The areas where young mullet was sensitive to a thermal effect were mapped. and a temperature-time equation logt(min)=17.9422+0.4202 T(℃) and a safe temperature equation T(℃)=(log1440—α)/b—2 were estabilished. A high temperatureshock of aam 15℃ for 2 minutes led to a mortality of 25%,that of ΔT=14℃ for 5 minutes led to a mortality of 15% and the maximum tolerable ΔT was less than 15℃. |
