在生理学实验中,为了记录腺体分泌或液的流动情况,需用记滴器。常用的有水银电鑰记滴器、气鼓记滴器和电动记滴器等。前两种装置麻烦,并不够灵敏。后一种虽较灵敏,但易出故障,且售价很高(每个100-200元),寿命不长。欲求简单灵敏而成本不高的记滴器,还是待研究的技术改革问题。最近我们教研组根据变压器的原理,设置了一种简单的电动记滴器,经过初步试用,尚感灵便,而造价估计不超过拾元。装置方法 In physiological experiments, in order to record the secretion of glands or fluid flow, the need for tick. Commonly used mercury key diarrhea, gas cylinder drop and electric record drops and other devices. The first two devices are troublesome and not sensitive enough. Although the latter is more sensitive, but prone to failure, and the high price (100-200 yuan each), life expectancy is not long. Demanding a simple and sensitive and not cost-dropping device, or to be studied the issue of technological reform. Recently, our teaching and research group according to the principle of the transformer, set up a simple electric drop device, after a preliminary trial, is still handy, and the estimated cost of not more than a pickup.
