THE INFLUENCE OF A MONOLAYER OF AN ALIPHA TIC ACID ON THE OSCILLATIONOF THE TEMPERATURE IN THE SURFACE-LAYER OF WATER

The influence of a monolayer of a palmitic acid on amplitude-frequency characteristics of temperature oscillations caused by thermal spots o f a surface film was experimentally determined in a Langmuir tank. An analysis of the power spectra the temperature oscillations were multim odal. In addition, no consistant differences between the spectrum for a pure surface and the spectrum for a surface covered by-an acid monol ayer were found. A roughened gain-frequency factor was found that is e qual to the ratio of the average period between the thermal spots to t he dispersion of the time series of temperature oscillations. The fact or significantly differed over a wide range of temperatures for a pure surface and for a surface covered with the monolayer. The experimenta l results do not confirm the existence of a leading frequency in the t emperature oscillations of a cold surface film due to an appearance of thermal spots.
