gradient
This term evokes a sense of smooth, continuous transition rather than an abrupt jump. It is a technical word used across physics, geography, and digital design to describe a slope or a shift in intensity. When used in a physical sense, it suggests a steady change in elevation that requires effort to overcome. In a visual or scientific context, it implies a spectrum. While a slope is a physical incline, a gradient can be an invisible force, such as a chemical concentration gradient in biology, moving from a high density to a low density.
Countable when referring to a specific slope or a single color transition on a screen. Uncountable when discussing the general physical property of a slope or the concept of a change in value.
Ý nghĩa
The rate of incline or slope of a road, railway, or piece of land.
"The steep gradient of the hill made the climb difficult."
