The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

As a differential detection is used between the intercarrier, the proposed algorithm overcome the high sensitivity to timing error of conventional algorithm and is robust to multi-path. The effect of sample frequency offset can't be ignored in a continuous OFDM system of a large number of subcarriers. The estimation precision of the conventional algorithm is low and the realization is complex. A joint estimation of sample frequency offset and fine frequency offset based on difference operation is proposed. As averaging use a large number of samples in a maximum likelihood algorithm, the estimation precision is very high. The use of difference operation cancel the effect of carrier frequency offset, and the proposed sampling frequency estimation algorithm is robust to carrier frequency offset.
最后,本文对连续系统中的采样频率和载波频率精同步技术进行较为深入的研究,由于子载波数目大的连续OFDM传输系统中,采样频率偏差不可忽视,以往的采样频率估计方法精度低、实现复杂,因此本文提出了一种基于差分处理的采样频率偏差和精载波频率偏差联合估计算法,利用了最大似然算法进行采样频率偏差的估计,由于采用了差分处理方法,消除了载波频率偏差对采样频率偏差估计的影响,采用的最大似然算法对大量样点进行平均化处理,所以,相对以往算法,提出的联合算法估计精度高,而且采样频率偏差估计对载波频率偏差具有鲁棒性。
