- It was during this time that he and Shockley calculated the maximum theoretical efficiency of silicon solar cells to be around 31 %.
- It's difficult to find maximum theoretical efficiency in a sentence. 用maximum theoretical efficiency造句挺難的
- The maximum theoretical efficiency is equivalent to the Carnot cycle, however the efficiency of real engines is less than this value because of friction and other losses.
- For example, the maximum theoretical efficiency of an SOFC using CO as a fuel increases from 63 % at 900 癈 to 81 % at 350 癈.
- This low percentage is, nevertheless, close to the maximum theoretical efficiency that can be achieved by an organism equipped with cilia as short as those of " Paramecium ."
- The maximum theoretical efficiency is 37, 50, 56, 72 % for 1, 2, 3, 36 pn junctions, respectively, with the number of junctions increasing exponentially to achieve equal effiency increments.

- The maximum theoretical efficiency of a heat engine ( which no engine ever attains ) is equal to the temperature difference between the hot and cold ends divided by the temperature at the hot end, all expressed in absolute temperature or kelvins.
- Maximum theoretical efficiency was limited by the relatively low temperature differential on either side of the piston; this meant that for a Watt engine to provide a usable amount of power, the first production engines had to be very large, and were thus expensive to build and install.
- The maximum theoretical efficiency of a heat engine is 1-T " c " / T " h " where T " c " is the temperature of the cold sink and T " h " is the temperature of the hot source.
