论开口系统稳定流动时热能与机械能的转换关系

Conversion Between Thermal Energy and Mechanical Energy with a Stable Flow in the Open System

开口系统稳定流动时由热能转换而成的机械能是工质的膨胀功，它与进出口推动功的代数和称为技术功，使用技术功的方式取决于热力设备的用途。

In the open system, the mechanical energy transformed from thermal energy consists of expansion work and the algebraic plus of push work of the entrance and exit, sum of which is technology work. How to use technology work depends on the usage of power equipment.
