marginal layer

mar·gi·nal lay·er

the outer, nonnuclear layer of the embryonic neural tube; into its fibrous network grow the longitudinal nerve fibers that eventually become the white matter of the spinal cord and brainstem.
Synonym(s): marginal zone (2)

Close above the test specimen surface a thermal marginal layer is created where it is possible to investigate the interference fringes.
The balanced increase of the thermal marginal layer thickness is visible in the figures.
This topic also covers the visualization of temperature fields in a marginal layer on the interface wood--the surrounding environment.
The paper was written within the work on the VEGA 1/0498/10 project: Application of holographic interferometry in research of marginal layer in heat transition appliances.
Interferometric visualisation of the temperature fields was mainly aimed at the thermal marginal layers close above the test specimen surface, at qualitative and quantitative analysis of temperature fields after certain times of heating of a test specimen by a point source (flame) from the below.
