前言本文含有近百个问题,这是汇集众人贡献的一次尝试。我们的文献中鲜见提出问题者。流体力学,或更一般说,科学和工程界的典型论文中都不提出问题。有些人显然是不愿意提出他们不能回答的问题。不过,不提出问题也部分是因为提问题不是我们流体力学界的传统。数学界可不一样,250年以前杂志上就出现了第一个问题专栏。 Preface This article contains nearly a hundred questions, this is a collection of people contributed to an attempt. Rarely ask questions in our literature. Fluid mechanics, or more generally, does not raise questions in typical papers in science and engineering. Some people obviously do not want to ask questions they can not answer. However, not asking questions is also partly because asking questions is not a tradition in our fluid mechanics community. The world of maths is different, with the first question column appeared in magazines 250 years ago.
