答案解析

<p> (1)92%电效应产铝:<br> 电流&times;0.3355&times;24&times;24&times;30&times;0.92%&times;10<sup>-3</sup><br> =114.5&times;0.3355&times;24&times;24&times;30&times;0.92&times;10<sup>-3</sup><br> =610.7T<br> (2)设完成14000时电效为X则<br> 2.98&times;V/电效&times;整流效率&times;10<sup>3</sup>=14000<br> 2.98&times;4.3/X&times;0.97&times;10<sup>3</sup>=14000X=0.9436<br> 则需再多产铝为:<br> 电流&times;0.3355&times;24&times;24&times;30&times;10<sup>-3</sup>&times;(0.9436-0.92)=15.667T</p>
