(一)沙重与浑水重关系线的实验:试验沙重与浑水重的关系,我们曾用黄委特制的1000C.C 细颈量瓶做过五个土样的试验,并绘成了浑水重沙重的关系线和浑水重与含沙量的关系线(参看表四和附图)。我站所用小磅秤,系称量2000克感量为一克的,灵敏性差,这样在称浑水重 (A) sand heavy and muddy water heavy line of experiment: the test sand heavy muddy water relationship, we have used the Yellow River Commission made a special 1000C.C neck flask five soil samples tested and painted The relationship between muddy water heavy sand and muddy water and sediment concentration (see Table 4 and attached drawings). I use a small scale station, Department of weighing 2000 grams for the amount of one gram, poor sensitivity, so that in the muddy water weighs
