ballast impedance

常見例句

最后，以一種板式無碴軌道為例，編程計算了各種電阻、電感參數(shù)和鋼軌等效阻抗。
The paper describes the principle of impedance transforming. The output network of a ballast and the frequency for each step are designed with this method.
簡單論述了阻抗變換法的基本原理，并采用此方法設計了熒光燈電子鎮(zhèn)流器輸出網(wǎng)絡以及各段運行頻率。
Owing to the impact of steel networks in ballast-less track, the equivalent impedance of rail track may be changed and the length of track circuit may be shorted.
但是，無碴軌道中縱橫交錯的鋼筋網(wǎng)絡將會使鋼軌等效阻抗發(fā)生變化，從而使軌道電路長度縮短。
