Accordingly, the dot texture shown does not map individual eletrons; instead, it suggests the cloud of electrical charge the electrons paint out during their symmetrical but untrackable quantum pattern of motion.

相应地，这里所展示的点状图并非是对单个电子的图示；相反，这张图展示了电子在做对称但不确定的量子式的运动时所绘出的电场。

The inverse of this quantity, the mean free path of the electrons, thus decreases with increasing temperature, consistent with a decreased size of metallic regions or increased scattering events at higher temperatures.

这种数量上的反转，电子的平均自由程，也随着温度的升高而减小。这种结果是与高温下金属区域的减小或者说对电子散射几率的增加是一致的。
