查询词典 efficiency

The small size of the conventional micro/small gas turbine results in blade path of small dimensions for the conventional turbine. The small dimensions have a deleterious effect on component efficiency. In the APGC operating under ambient pressure, larger specific volume results in large dimension of blade path and higher component efficiency, and the higher overall thermal efficiency also.
