直接在动物或人类身上使用的热量计通常操作困难，反应非常缓慢。这里描述的梯度量热计只有42秒的时间滞后。是专门为研究TEMP的反射机制而设计的。控制力。物体完全被一层导热物质包围，其外表面保持恒定(基准)温度。由受试者以任何方式传递到导热层内表面的热将根据传统的热定律传递到导热层的内表面。临时工。通过导热层的梯度被用来计算受试者所损失的热量。
Direct calorimeters for use on animals or humans are generally difficult to operate and respond very slowly. The gradient calorimeter described here has a time lag of only 42 sec. and was specifically designed for studies of reflex mechanisms involved in temp. control. The subject is completely surrounded by a layer of thermally conducting matter, the outside surface of which is held at a constant (reference) temp. Heat transferred in any manner by the subject to the inner surface of the thermally conducting layer will be transferred across the layer in accordance with conventional heat laws. The temp. gradient across the thermally conducting layer is used to calculate the heat lost by the subject.
