在将任何理论公式与实验进行比较时，我们不应忘记，我们从实验中直接得到的是两种温度下辐射的差别。最后再提一点。如果给定温度的全部辐射由（5）表示，则温度可以由a的值来定义。反之，则意味着分布定律在所有温度下都是一样的，这与通常观察到的”红热”和”白色热“是不一致的。“现在a的维度是时间的维度;所以温度可以由时间定义，或者（通过传播速度）由线定义。因此，在兰利教授的曲线中，它代表了一个模具中的能量分布，作用光谱，对应于最大纵坐标的波长可以被认为是曲线所涉及的温度的线性规格。
In comparing any theoretical formula with experiment, we must not forget that what we learn directly from the latter is the difference of radiations at two temperatures. One more remark in conclusion. If the complete radiation for a given temperature be represented by (5), it follows that temperature may be defined by the value of a. The contrary would imply that the law of distribution is the same at all temperatures, and would be inconsistent with ordinary observation respecting" red" and" white heats." Now the dimensions of a are those of a time; so that temperature may be defined by a time, or (through the velocity of propagation) by a line. Thus in Prof. Langley's curves, which represent the distribution of energy in a die, action spectrum, the wavelength corresponding to the maximum ordinate may be regarded as a linear specification of the temperature to which the curve relates.
