摘　　要：通过实例介绍了应用动量定理时要注意的问题,并指出用功能原理解题时因忽略了动量定理所常犯的错误,最后对一道常见的实验题进行了深入、定量的讨论,使人们对动量定理有更全面的理解。The paper introduces the problems which should be paid attention to during the application of the momentum theorem from various examples. It points out the common mistakes during the application of the principles of work and energy without considering the momentum theorem. The paper also discusses a common experimental question in detail, which could lead to a comprehensive understanding of the momentum theorem.
