  1. Flow separation produces pressure fluctuations of large amplitudes, possibly with the dominant frequencies differ from up - stream blade wake passing frequency and its harmonics

    尾緣氣流分離產生的壓力波動頻譜中含有上游葉片尾跡頻率及其倍頻的分量，但其頻譜可能比較復雜，並非單一地受上游葉片尾跡影響。
  2. On the rotor blade pressure surface, the dominant frequencies of unsteady surface pressure are the up - stream blade wake passing frequency and its harmonics, and the amplitudes of pressure fluctuations decrease from leading edge to trailing edge

    轉子葉片吸力面非定常壓力受葉片附面層和上游葉片尾跡共同影響，其主導頻率為上游葉片尾跡頻率及其倍頻，但是在吸力面前部氣流加速區壓力波動幅度沿流向增大，而在吸力面後部氣流減速區壓力波動幅度沿流向減小。
  3. Wake up by and by, and look to see what done it, and maybe see a steamboat coughing along up - stream, so far off towards the other side you couldn t tell nothing about her only whether she was a stern - wheel or side - wheel ; then for about an hour there wouldn t be nothing to hear nor nothing to see - just solid lonesomeness

    等到慢慢醒來，看看情況，也許會看到一隻輪船一路喘著氣，往上游開去。只因為是在對岸老遠的地方，所以除了它的明輪是裝在船兩旁或是在船尾之外，什麼也看不清。並且在一個鐘點以後，連聽也聽不見什麼了，看也看不見什麼了留下的只是一片冷清。
