摘　　要：　测流时,脉动水流会使测流过程中的水位、水深、流速与实际产生误差,从而对实测流量的精度产生一定影响,造成量值误差。在量值已成为当前水利规划使用依据时,有必要注意其影响,从而提高使用精度。Pulse flow can generate influence to the precision of measuring flow and eventuate magnitude error, for which yield the error for water-level, depth and flow when measuring. Pulse flow influence must be noticed for to improve its precision especially when the magnitude becomes the reference in water conservancy plan.
