在生理學實驗中,為了研究生理分泌及体液流動的情况,有時需要持續而又準確地記錄體液的滴數。過去我們曾應用過好些種類的記滴方法,例如水銀電鑰記滴器,氣壓記滴器,氣鼓記滴器及電動記滴器等。這些方法在使用時各有其缺點:或則裝置麻煩,或則液體長期黏附,或則壽命不長,不能長期持續應用,常常在实驗進行中,不能很準確地記錄實驗結果,增 In physiological experiments, in order to study physiological secretion and fluid flow, it is sometimes necessary to continuously and accurately record body fluid drops. In the past, we have used several types of droplet method, such as mercury key, dropper, drum drop and electric drop. These methods have their own drawbacks in use: or the device trouble, or long-term liquid adhesion, or life is not long, not long-term continuous application, often in the experiment, can not accurately record the experimental results, increase
