dilatací

Dilatace is a Czech term that translates to "dilation" or "expansion" in English. It generally refers to the process of increasing in size, volume, or extent. In physics and engineering, dilatace commonly refers to thermal expansion, where a substance's volume increases due to an increase in temperature. This phenomenon is governed by the material's coefficient of thermal expansion.

The concept of dilatace also appears in medicine, where it can describe the widening of a body opening or passage, such as the dilation of the pupil of the eye or the dilation of the cervix during childbirth. In materials science, dilatace might describe the increase in the size of a material under stress or strain. In a broader sense, dilatace can refer to any kind of widening or stretching.
