However, there are gaps in scientifi c knowledge about exactly how colour interacts with other factors to infl uence a fabric’s ability to block ultraviolet protection factor (UPF).
但是，关于颜色到底是怎样与其他因素作用来影响布料紫外线防护系数（UPF）的科学知识还存在一些缺口。

The vegetation cover and management factor ( C ) in the universal soil loss equation (USLE) is an index to evaluate this effect, which has been studied deeply and used widely.
C will cause harmonic flow reactive (power factor) compensation capacitor current increase significantly, resulting capacitor will soon be put into operation in damage.
