弦振动法测定液氮的密度

DENSITY MEASUREMENT OF LIQUID NITROGEN BY USING THE METHOD OF STRING VIBRATION

本文提出了用弦振动法测定液氮的密度,讨论了减少实验误差的方法,为液氮的生产和应用提供了参数。

In the paper, density measurement of liquid nitrogen by uising the mothod of string vibration is prsented. We discuss the methcd of decreasing experimentat error. Provide Parametor for and using of LiQuid nitrogen.
