rated efficiency

Doctors are rated based on quality of care and cost efficiency.

医生的排名根据医疗服务质量和成本效益来制定.

Leaving the rated load, especially with low load and free running operation, Ihe efficiency of turbocharger and ratio boost pressure decrease, leading to the shortage of air in cylinders and worsening of combustion, and the economic, power and exhaust performances deteriorate.

当偏离标定点，尤其在低负荷和空转工况工作时，增压器效率降低，增压压力明显下降，导致气缸供气不足，缸内燃烧不良，柴油机的经济性能、动力性能和排放性能将严重恶化。

This paper presents the major parameters of hydraulic turbines one by one, such as rated head, specific rotating speed and specific speed coefficients, unit flow, unit speed, cavitation coefficient, efficiency, stability etc.

对构皮滩水电站水轮机的额定水头、比转速及比速系数、单位流量、单位转速、空化系数、效率、稳定性等逐一进行论述，介绍了基本参数和参数水平。
