half wave line 中文意思是什麼
half wave line
解釋
半波長線-
The moment the bells stopped, those banked masses broke and poured over the line like a vast black wave, and for as much as a half-hour it continued to flow, and then it solidified itself.
鐘聲一停止，那群堆千積萬的人就四分五散，好象一片黑色的洪濤巨浪，沖到那個防線里來，繼續奔流了半個鐘頭之久，這才又凝固起來。 -
If line length is half wave at a certain frequency and both the load resistance rt and source resistance rs are higher than the characteristic impedance zo, then both the voltages at input and at load are maximum at that frequency and both the voltages at input and at load are minimum at half of that frequency
負載端電阻及電源電阻均高於傳輸線特性阻抗情況下，當線長為某頻率波長之半波，則輸入端與負載端電壓在該頻率均為最高，在該頻率之半時則電壓均為最低。 -
If line length is half wave at a certain frequency and the load resistance rt is lower while source resistance rs is higher than the characteristic impedance zo, then both the voltages at input and at load are minimum at that frequency and both the voltages at input and at load are maximum at half of that frequency
負載端電阻低於傳輸線特性阻抗及電源電阻高於傳輸線特性阻抗情況下，當線長為某頻率波長之半波，則輸入端與負載端電壓在該頻率均為最低，在該頻率之半時則電壓均為最高。
