用堰箱测涌水量时,箱内水位观测精度直接影响着水量的计算。在用空气压缩机抽水时,由于水的冲力,堰箱内水位波动剧烈,测水位需用很长的时间,且精度不高。为了求得精确的资料,我们采用了小漏斗在堰箱内测水位的方法,克服了水位波动大难以确定稳定水位的困难。现将其 When using the weir tank to measure the influx of water, the accuracy of water level observation in the tank directly affects the calculation of the amount of water. In the air compressor pumping, due to the impact of water, weir tank water level fluctuations, water level measurement takes a long time, and the accuracy is not high. In order to obtain accurate data, we use a small funnel in the weir tank water level measurement method to overcome the water level fluctuations difficult to determine the difficulty of stabilizing the water level. Now it
