impermeable的意思|示意

Impermeable is an English adjective that refers to a material or surface that does not allow liquids or gases to pass through, blocking it. It is derived from the Latin word impermeabilis, from the verb permeare (“to permeate”).

Common uses for impermeable surfaces include preventing water from entering a basement, or avoiding water damage in buildings. In the construction of highways and roads, impermeable layers are used to prevent water from reaching the underlying soil.

The term impermeable is often used in the context of climate change. For example, the earth’s atmosphere functions as an impermeable barrier that prevents potentially hazardous radiation from entering the planet. Similarly, surfaces covered with ice and snow can act as impermeable membranes against wind and water.

In medicine, impermeable barriers are important in dialysis, artificial skin production, and other treatments. Synthetic membranes like plastic and rubber are made to be impermeable to certain solutions, allowing them to be used in the production of dialysis machines and artificial skin to be used in medical treatments.

The term “impermeable” can also be used to describe a material’s ability to prevent the entry of certain substances. For example, certain types of fabrics are designed to be impermeable to water and other liquids, avoiding damage or staining of the fabric.

In summary, “impermeable” is an adjective used to describe a material or surface that does not allow liquids or gases to pass through, acting as a barrier. It is most commonly used in the context of construction, climate change, and medicine.
