实验研究了硝酸、稀土元素和其它主要盐份的浓度以及温度对模拟高放废液中超声速度的影响。结果表明：Na、Al、Fe等主要盐份浓度的影响较大，硝酸、稀土元素浓度和温度的影响较小。萃取前后30％TRP)－煤油中的超声速度变化很小，可以忽略不计，而温度的影响较大。搅拌池中超声体积分数的实验测量结果表明：有机相体积分数在5％～60％范围内，测量值与真实值之间的相对偏差在±10％以内。 The effects of nitric acid, rare earth elements and other major salt concentrations and the temperature on the ultrasonic velocity in simulated high-level liquid waste were experimentally studied. The results show that Na, Al, Fe and other major salt concentrations have a great influence on the concentration of nitric acid, rare earth elements and temperature. 30% TRP before and after extraction) - The change of ultrasonic velocity in kerosene is small, negligible, and the influence of temperature is greater. The experimental results show that the volume fraction of organic phase in the range of 5% ~ 60%, the relative deviation between the measured value and the true value is within ± 10%.
