各种温度表的示数都滞后于被测介质温度的变化,这就是温度表的热惯性。它是海水温度测量误差的重要来源之一。研究热惯性有着重要意义。然而在国内外的专门文献中,对这一问题的阐述是太不够了。本文叙述了几种海洋温度计热惯性的实验研究结果,得出了热惯性的数据,指出在予定水层测量时必须的最低延迟时间,并给出了深度温度计在作温度梯度观测时的允许下潜速度。
Various thermometers have lagged behind the measured medium temperature changes, which is the thermometer thermal inertia. It is one of the important sources of seawater temperature measurement error. The study of thermal inertia is of great significance. However, in the specialized literature at home and abroad, the elaboration of this issue is too inadequate. In this paper, the experimental results of thermal inertia of several marine thermometers are described. The data of thermal inertia are obtained. The minimum delay time necessary for the measurement of the predetermined water layer is pointed out. The allowable depth of the depth thermometer is given when the temperature gradient is observed Submarine speed.
