  1. In the second method, wavelet transform is combined with modal transform, and transient travelling - wave signal is used. after three phase signals are decomposed into their modal components, the wavelet transform coefficient of ground mode can be used to identify approximate position of fault, and the wavelet transform coefficient of aerial mode is used for identifying arrival time of traveling - wave

    第二種方法將小波變換與模式變換理論結合起來，採用的是暫態行波信號，首先將三相信號轉換成模式分量，零模分量的小波變換系數用於判別故障的大致位置，然後利用線模分量的小波變換系數來確定行波到達時間。
  2. In the second chapter, a wideband mimo channel model with multiple - tap was integrated according to the angle of departure of the transmitting signal and its spread angle, the angle of arrival of the receiving signal and its spread angle, power azimuth spectra, doppler spectrum and the geometric construction of antenna array both sides of transmit and receive, on the basis of full research on the theories of space - time channel model proposed in the recent literature

    第二章在對最近文獻中提出的一些空時通道模型理論進行詳細研究的基礎上，根據發射信號的離開角及其擴展角、接收信號的到達角及其擴展角、功率方位譜、多普勒譜和收發兩端天線的拓撲結構，綜合了一個多抽頭的寬帶mimo通道模型。
  3. The second part mainly reviewed the study history, actualities and existinbg problem. this is helpful for the model building, variables selecting and parameter estimating, hi the third part, the arrival process and serve process are studied based on the survey data, especially the delay process is mainly analyzed including the dispersion vehicle headway time distribution

    第三部分則根據實測數據，對交叉口車輛的到達過程和服務過程作了詳細的分析，特別分析了車輛的受阻過程，並用對數正態分佈擬合排隊車頭時距的分佈，為模型的建立和車輛延誤過程的模擬奠定了基礎。
