Methods: Subjects were measured with OrbscanⅡcorneal topography system. Anterior and posterior corneal radius of curvature and thickness of the points located 1.5 mm, 2.5 mm, 3.5 mm and 4.5 mm away from the corneal apex on certain meridians, including 0°,30°, 60°,90°,120°,150°,180°,210°,240°,270°,300°and 330°meridians,were collected.
1. Hsiakuan point topography and oberservation: From superficial to deep: the skin, the superficial fascia, the parotid fascia, the parotid gland, the masseter, the space between the zygomatic process of the temporal bone and the mandibular notch, the lateral pterygoid muscle.
As for the four transect lines, the east and the northeast scored higher in each diversity index than the others due to less human disturbance, gentler topography uplift and more intercepted materials and energies.
The distribution of microbiotic crusts were studied, while human disturbance, aspect, topography, vegetation structure and other factors affecting it were obtained from the analysis of survey data from 78 sample plots.
Topography and elementary components of the brake block's wear surface are analyzed by employing SEM and EDAX patterns, revealing its tribological behaviour and wear mechanism.
Increasing the grinding depth or the wheel velocity makes grinding temperature and residual tensile stress of the surface rise, which deteriorates the surface topography.
During scanning, AF/PSTM could get two optical images of refractive index image and transmissivity image, and two AFM images of topography image and phase image.
