This variability has led many people to think of it as a spectrum of symptoms rather than a single, clear-cut syndrome. And that variability makes it hard to work out what causes it.

这种多变性令很多人认为它的症状多样而不是单一明确的，这种多样化加大了对其病因的研究难度。

We also used LED panels in an open section that provide excellent light spectrum.

He also led a crusade to free up another huge chunk of spectrum, culling it from military airspace and idle swaths to create the same sort of anything-goes turf that served as the spawning grounds for Wi-Fi.
