一、岐离的地方伯努利(Bernoulli)定理是流体力学中一个极重要的规律。在大学普通物理教学过程中学生认为这个定理难懂,教师亦认为这个地方难讲。因为它的重要和难懂,在讲完该定理之后,各书都列举了许多的例子,一则以说明它的应用广泛,同时为了在举例的当中,加深学生对这一基本原理的认识和了解。可是,在仔细阅读了这些例子之后,就会发现它们之间存在着岐离和不一致的地方。伯努利定理的本身已经相当的复杂和难懂,加以各书岐离的、不一 First, the strange place Bernoulli theorem is a very important law of fluid dynamics. Students in the university general physics teaching process think this theorem difficult to understand, the teacher also thinks this place is hard to say. Because of its importance and comprehension, after enacting the theorem, many examples are given in the books, one to illustrate its wide application and to deepen students’ understanding of this basic principle and to exemplify, To understanding. However, after reading these examples carefully, you will find some discrepancies and discrepancies between them. The Bernoulli theorem itself has been quite complex and difficult to understand,
