| 摘 要： | 作者重新界定了效率和效能定义的内涵,并将之应用于驱油用表面活性剂烷基苯磺酸盐降低油水界面张力的表征;通过试验和计算。认为效率和效能可以作为评价和筛选驱油用表面活性剂的两个标尺来使用;而表面活性剂亲油基的碳链长度和亲油基的支化是影响效率和效能的主要结构因素。

| Abstract: | The connotation of efficiency and effectiveness was redefined and the definitions were used to describe the characterics of the flooding surfactants in reducing oil/water interfacial tension.The testing and calculating results show that efficiency and effectiveness can be treated as two gauges to evaluate and choose flooding surfactants.And the length and branching of alkyl chain in the hydrophobic group are main structure factors affecting surfactants' efficiency and effectiveness. |

| Keywords: | Efficiency Effectiveness Alkylbenzene sulfonate Oil/water interfacial tension |
