摘要：

运用矛盾论、动与静的辩证关系，整体与局部的辩证关系解决简单管路、复杂管路所涉及的阻力损失的变化、流量变化及静压强变化等定性问题。教学实践表明，用哲学原理解决此类问题不仅原理清晰，判断准确、快速，而且提高了学生的辩证思维能力，获得了绝大部分学生的认可与欢迎。

关键词: 辩证思维, 矛盾论, 流体流动, 定性分析

Abstract:

The law of contradiction, the dialectical relationship between the dynamic and the static state, and that between the whole and the part were used to solve the qualitative problems of fluid flow. The problems include the variations of friction loss, static pressure and flowrates in simple and complicated pipelines. The teaching practice showed that solving the above problems by philosophy principles has the characteristics of clear principles, accurate and quick judgement, and could enhance the students' dialectical ability. This method was approved and received by the greater part of the students.

Key words: Dialectical thinking, Law of contradiction, Fluid flow, Qualitative analysis
