求翻译：在分析过程中，量气筒液面下降到某位置时听到DF3、DF4同时的响声，这是DJ2正好与液面接触。这时量气筒中空出的部分容积，就是取样量。提高DJ2的位置，则增大取样数，降低DJ2的位置，则减少取样数。要求液面接近量气筒膨大部分底部时，取样结束。是什么意思？

In the analysis process, the level drops to a certain amount of pump position to hear DF3, DF4 same sound, which is DJ2 coincided with surface contact. Then hollow out part of the amount of pump capacity, is the sampling volume. Improve DJ2 position, then increase the number of samples, reducing the

In the process, punching bag volume drops below a certain level-3, DF DF location when he heard the sound of the bells, while 4 2 DJ coincides with this is contact with liquid. When the volume of tubes hollow out part is the sampling volume, volume. The location of DJ 2 samples, the increasing numbe

When the analysis process, measures the air pump liquid level drops to some position hears at the same time DF3, the DF4 sound, this is DJ2 just right and the liquid level contact.By now measured the partial volumes which in the air pump emptied, was the sample quantity.Enhances DJ2 the position, th

Analysis process, pump of liquid surface drops to one location heard DF3 and DF4 and noise, DJ2 coincided with surface contact. Pump hollow part of the volume, is sampled. Improve DJ2, you increase the number of sampling, reducing DJ2, you reduce the number of samples. Request liquid surface close t

In the process of analysis, pump level down to a position heard DF3 and DF4 and sound, this is DJ2 is contact with the liquid surface. Pump hollow part of the volume, is sampled. Improve DJ2, you increase the number of sampling, reducing DJ2, you reduce the number of samples. Requested surface close
