When a wave travels uniformly in all directions from a small source, the intensity varies inversely as the square of the distance.

当波从小扰动源向各个方向均匀传播时，其强度的变化与距离的平方成反比。

Nor is it possible simply to crank up the power of the source beam, because infra-red light at high intensity can cause eye damage.

他说，“多数光不会你想让它到哪它就到里”。 也不可能简单地增强光束的强度，因为高强度的红外光会伤害人眼。

Consequently, we adapt to use lamps as the main lighting source of the restaurant so the intensity of light can easily be adjusted.

从而，我们开始适应使用灯具作为我们餐厅的主要光源，这样一来，光照的强度能够很容易地进行调整。

Another problem is a more pervasive albeit lower-intensity source of cadmium: phosphate fertilizer.

But it certainly does intimacy, and even intensity, with stunning fidelity to the source material.
