All elastograms were evaluated for the lesion visibility, relative brightness, and margin regularity and definition by using a four-point scale.

应用四点积分标准评价所有弹性图像的病变可视性、相对明亮度、边缘规则性和有限性。

As relative orientations change, the brightness of reflections may also change, sometimes suddenly.

随着相对方位的变化，反射光亮度也随之变化，有时亮度的变化是突然发生的。

This isn't a liable solution, because when the billboards turn to follow the camera, their Angle relative to the light source will change, and so will their brightness.

这不是一个主观的解决办法，因为当粒子块朝向摄像机时，他们与光源的角度会改变，他们的亮度也会随之而变。

The small size of the red dwarf stars, typically with spectral types K and M, gives a greater relative drop in brightness when low-mass planets pass in front of them, making it easier to search for planets around them.

V4, where the light reflected from a surface is compared with that reflected from surrounding surfaces, in order to control for relative rather than absolute brightness.
