摘要:

Light diffraction and finite amplitude loss are used to measure the acoustic nonlinearity parameter for water, methanol, liquid nitrogen, and liquid helium‐II. In all cases, the finite amplitude loss technique yielded higher values than the light diffraction technique or thermodynamic estimates from published data.
