在11.8章节中表3的这么的一段话想探讨下* f$ K' ]3 ~/ k/ R1 o
To allow for the fact that the average temperature of windings of universal motors, relays, solenoids and

parentheses apply when thermocouples are used. For windings of vibrator coils and a.c. motors, the figures

" _! [6 z7 l% E7 |! b前面一句话 说 universal motors 应该是通用电机(交直流电机)的意思吧,说线圈的温度电阻法用前面不带括号的数值来判定,热电偶法用带括号的数值来判定,但是后面又来了一句交流电机用不带括号的数值适用于电阻法和热电偶法,这里我觉得有点矛盾请各位大大解惑谢谢了。
