| 摘 要： | 研究了流体噪声的湍流传递行为及信号源的性质对相关测速系统的影响，分析了相关测速系统的系统误差，并提出了理论修正该误差的方法，使得相关测速成为一种绝对的测量方法。在理论分析的基础上进行了实验研究，理论与实践得到了较好的统一。

| Abstract: | In this paper, the turbulent transport behavior and the nature of the noise are discussed.The systematic error is analyzed in detail and the theoretical calibration method is proposed,which makes the velocity measurement by time-correlation an absolute one.The theoretical investigation is verified with the experiment. |
