«Because the melt zone is very focused and narrow, we're able to achieve a very large temperature gradient between the solid and liquid phases, which results in high - quality crystal growth.» (sciencedaily.com)
An instrument in space will experience large temperature gradients because one side will face the hot sun, while the others face cold space. (sciencemag.org)
The height above ground level must be specified, as on many occasions large temperature gradients exist in the lower layers of the atmosphere. (wattsupwiththat.com)
