Description of the development:
()
Research methods: - the complexity of measurements C and D are achieved by using a single method of recording acoustic changes in these variables when you change the parameters of the state; - the characteristics of C and D are defined at the same thermodynamic conditions and without changing the sample; - applied a precision pulse-phase measurement method. The equipment includes a camera for absolute measurements of the velocity of propagation of ultrasound on the saturation line, pycnometer and a camera for relative measurements C and D.
