Instead, the top of the wall undergoes compression.

This might be due to increased skin cell replication at sites under stress where cells rapidly slough off or undergo compression or abrasion.

The compression space is intercooled, so the gas undergoes near-isothermal compression.

There are three possible relationships between temperature and pressure in a volume of gas undergoing compression:

Substances, especially fluids in which intermolecular forces are weak, also undergo compression upon the application of pressure.

A premixed fuel-air charge undergoes tremendous compression until the fuel self-ignites.

The test measured changes of absorption of gamma rays in the metal of the sphere as it underwent compression.

The compression space is assumed to be intercooled, so the gas undergoes isothermal compression.

A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression.

The ratio of atomic isotopes in the debris hinted that the fusion fuel had undergone "enormous compression," the secret to the bomb.
