transformation of mass-energy

The effects of pressure, mass velocity, inlet subcooling, heat flux, and exit throttle on the flow instability were determined in the modeling experiment. The thresholds of the flow pattern transformation instability and that of the density wave instability were obtained.

通过模型试验确定了压力、质量流速、入口过冷度、热流密度、出口节流阻力等因素对不稳定性的影响，得出了流型转化型和密度波型不稳定性的界限。

Firstly , The transformation of curriculum values: from elitist education to mass education.

从“精英主义教育”转向“大众主义教育”: 课程价值观的转型.

Along with the coming of mass consumer culture times, the transformation of poesy style in 1990s took place.
