impulse duration 中文意思是什麼
impulse duration
解釋
脈沖期間-
The impulse is dependent upon the duration of the shock wave as well as its pressure.
脈沖的大小又取決于沖擊波的延續時間及其壓力。 -
Impulse wave has been examed on high speed wide frequency spectrum oscillograph, we have a satisfaction result on amplitude, shape, and shot time duration
發射電路經過高速寬帶示波器的輸出測試，得到了比較理想波形和幅度以及納秒級寬度的窄脈沖。 -
The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds, the system has to be adaptive, and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing
但由於聲回授通道的特殊性和復雜性，普通的自適應演算法無法滿足要求，必須採用一些十分復雜的演算法，這樣一來，實時性的問題變得十分突出。快速lms newton演算法的提出，給自適應聲回波對消問題的解決開辟了新的途徑。該演算法集lms演算法的簡單易行性和newton演算法的快收斂性為一體，是一種非常有應用前景的自適應演算法。 -
Effects of current passing through the human body. part 2 : special aspects. chapter 4 : effects of alternating current with frequencies above 100 hz. chapter 5 : effects of special waveforms of current. chapter 6 : effects of unidirectional single impulse currents of short duration
通過人體的電流的效應.第2部分:特殊信號形式.第4章:頻率在100hz以上的交流電的效應.第5章:特殊波形電流的效應.第6章:短時間單向脈沖電流效應 -
By the theory of z transformation of linear system and matrix, we proved the validation of the averaging filter method using in ietd to cancel oscillation. then we illustrate the disadvantage of using averaging filter and give a new averaging filter that we note as phase - modified averaging filter, which can reduce the disadvantage. at the end of this chapter, we study the potent of reducing the time - cost of ietd by taking account the short duration characteristics of incident impulse
本文第二章，首先簡述了時域積分方程遞推解法（ ietd ） ，然後推導了應用於旋轉對稱體的，能夠減少計算量的ietd方法，重點闡述並應用線性系統的z變換理論和矩陣理論研究了ietd方法中遇到的穩定性問題，從理論上證明了平滑濾波技術的有效性，指出了它對計算精度的影響，並在分析的基礎上提出了新的相位修正平滑濾波方法。
