论技术功

Study on Technical Work

针对现有文献对技术功的概念缺乏深入探讨,甚至存在错误理解的现状,通过对稳态流动能量方程中能量转化关系的分析,结合流体膨胀或压缩过程的热力学和流体力学特性,揭示了技术功定义式成立的条件,指明了技术功概念的经验性,论证了技术功定义式的唯一性,明确了技术功定义式的适用范围和条件,厘清了技术功的本质,并对技术功与其他功的关系进行了分析。

Because of the lacking of analysis of technical work,and even the existing errors in understanding,the condition of technical work definition has been revealed through the analysis of the energy conversion in steady flowenergy equation,combining with the fluid thermodynamics and fluid mechanics characteristic of expansion or compress process. The concept of technical work has been pointed out is to be empirical,the uniqueness of technical work definition has been demonstrated,the applicable scope and conditions of technical work definition has been clear,the essence of technical work has been clarified,and the relationship between technical work and other work has been analyzed.
