    中文摘要:
          温度漂移是影响超声波流量计测量精度的一个重要因素,本文从算法上提出一种不受其影响的数学模型,以使相应的硬件简单化.该方法已应用在超声波流量计中,收到了很好的效果.
    英文摘要:
          The temperature drift is an important factor to effect the measurement precision of the ultrasonic flowmeter.This paper puts forward a model of maths which has not an effect on the temperature drift,and it makes the relative hardware simple.The method in this paper is used by the ultrasonic flowmeter and a very good effect has been obtained.
