Methods 58 cases patients needing endocardiac orthoptic surgery were enrolled in this study, they are divided into control group and SFI group randomly. Injecting of SFI 1ml/kg by intravenous before CPB was performed in group SFI, tidal volume, Pmax , Pmean and calculating Crs and RI during 10 min , 30 min , 60 min after the trachea intubating, in the beginning of CPB and during 10min, 60min, 120min after CPB were recorded.

选择临床心内直视手术病人58例，随机分为对照组和SFI组，SFI组于CPB前予SFI 1ml/kg静注，记录气管插管后10、30、60 min，CPB手术开始时，CPB停止后10、60、120min时的潮气量、气道峰值压、平均气道压并肺顺应性和呼吸指数。

Theoretical analysis shows that with equispaced null-subcarriers or data subcarriers, the CFO estimation are independent to channel zero locations.

在接收端，以多径区域能量和噪声区域能量之比作为符号定时的判决函数，从而使所形成的峰值更加明显。

Thirdly, the maximum-likelihood CFO estimation algorithms based on null-subcarrier are investigated, and it is shown that the maximum-likelihood CFO estimation algorithm based on equispaced null-subcarriers is equivalent to the CFO estimation algorithm utilizing the correlation of repeated training sequences.
