The LDMV was used to measure steady blood flow velocity, diameter of vessels and pulsation flow.
该仪器可测定单一血管血流速度、血管直径和搏动幅度。

Comparing with involute gear pump, the instant displacement is in direct proportion to the angular velocity of the gear and stable without pulsation.
对比渐开线齿轮泵，单圆弧齿轮泵的瞬时排量与齿轮角速度成正比，且稳定，无脉动。
