摘　　要：本文论述了枯水期沱江流域、内江市市区花萼村至大自然河段水体的物理化学特性．主要测定其pH值、电导率、密度、表面张力、硬度、溶解氧、相对介电常数和相对黏度等物理化学特性参数。实验结果表明：内江市市区段沱江水的pH值为8．24；总硬度为13．04°；电导率为0．499ms／cm；溶解氧含量为4．56mg／L；表面张力为70．86×10—3N／m,相对介电常数为73．066；密度为1．016g／cm3；相对黏度为1．008。This article discusses Tuojiang water on the physical and chemical properties from HuaE villige to DaZiran during low water term of Tuojiang catchment. Some physical and chemical properties including pH,conductivity,interfacial tension,hardness,dissolved oxygen, relative dielectric constant and relative viscosity have been deter-mined. The experimental result showed：the pH of 8.24, the hardness of 13.04°, the conductivity of 0. 499ms/cm , the dissolved oxygen of 4.56 mg/L, the interfacial tension of 70. 86 × 10^-3 N ·m^-1 ,the relative dielectric constant of 73. 066 ,the density of 1. 016g/cm^3 , the relative viscosity of 1. 008.
