Figure 9 shows a composite profile of seismic reflection and seismic attenuation.
Acoustic impulse responses represent a range profile of echo reflections that have been used to reveal spatial reflection patterns of bat-pollinated flowers and different leaf shapes and determine their role as nectar guides for echolocating bats (von Helversen and von Helversen, 1999; Simon et al., 2011).
The study developed within an experimental approach, allowed us to define four consistent profiles of metacognitive reflection, each illustrated by specific behaviours that reflect a type and degree of metacognitive awareness, knowledge, control and regulation of own learning.
We focused on the frontal wedge of the Japan Trench and used 12 profiles of seismic reflection and refraction survey data at the frontal wedges of the Japan Trench to analyze the topographical parameters and obtain the frictional properties (Figure 1).
In the present study, we obtained the slope angle of the sea-bottom surface, the décollement dip angle β, and the angle between the décollement and back-stop interface ω from the 12 profiles of seismic reflection and refraction survey data taken at the frontal wedges of the Japan Trench (Figures 1 and 3).

In the present study, we defined the average Q values having negative percentage perturbation (yellow to red) as 'high-attenuation' and those having positive percentage perturbation (yellowish green to blue) as 'low-attenuation.'

The degree of crystallinity increased to the level of 17 18% at ×20 and turned to decrease after ×60, but the degree of crystallite orientation reached at a high level already at ×10 and did not change significantly and the half-height width of reflection profiles stayed almost at a constant level, while the Young's modulus increased up to ca. 300 MPa at ×100 and then fell rather discontinuously.
As a preliminary test of the apparatus, the reflection profile of a Mo/SiO2 multilayer mirror prepared by an ion beam sputtering technique, which is designed as a reflection polarizer for use of 13.9 nm, has been measured by the apparatus.
