工程伦理学是20世纪后期兴起的一门交叉学科。文章首先分析了把技术开发与技术使用分开，从而回避工程师责任的做法，进而剖析了认为工程是科学的应用和工程是实现社会价值的简单工具等观点，指出工程与伦理密切相关，工程师应当增强责任意识。

Engineering ethics is an inter-disciplinary subject developed in the late 20th century. But many engineers doubt how engineering connects with ethics. This paper analyses the view of engineering as application of science and the view of engineering as mere instrument for human values. Engineering is not an application of science to make risk-free products but risk-involving inherently and has great ethical implications. Engineering is more than an instrument for human values. On the contrary it has great reaction on social values. Engineering ethics should be studied on the basis of the interrelation of engineering and society. Within this framework engineers' responsibility is discussed.
