distorted pulse 中文意思是什麼
distorted pulse
解釋
畸變脈沖-
When the pulse width of input gaussian wave packet was reduced and the length of forbidden region retained, the result displayed the output signal distorted seriously and its spectrum changed very hard. a frequency above the cut - off frequency became the main frequency and the group velocity was below than c
在保持截止區長度不變，而減小輸入高斯波包的脈沖寬度時，模擬顯示輸出波形嚴重失真，而且，頻譜也發生很大的變化，主頻已變為一高於截止頻率的頻率，群速度小於光速c 。 -
The followings were discovered in the simulations of undersized waveguide : when the pulse width of input signal, a gaussian packet, is rather wide, the output signal distorted little. a superluminal group velocity 3. 21c was revealed when the wave packet crossing 50mm forbidden region
對凹陷波導（ undersizedwaveguide ）的模擬發現：輸入脈沖寬度較大的高斯波包，模擬結果顯示輸出波形失真較小，經過計算得到電磁波包穿過長50mm的截止區時，電場的幅度衰減了- 41 . 5db ，群速度為3 . 21c 。
