Constant Friction

Ring compression tests were conducted at constant true strain rates in the temperature range of 900–975°C. The constant friction shear factor, m, was determined using a calibration chart. Scaling was permitted during the experiments in which a glass based lubricant was also used. Frictional conditions were affected most by the rate of strain; increasing it led to lower values of m.

The interfacial friction properties of GCL and geomembrane under different hydration conditions are discussed. In addition, the ionic solubility of hydration solution, the size of hydration normal stress and test conditions will affect the shear strength of GCL. In this paper, the friction properties of GCL upper geotextile and geomembrane interface are discussed from the following aspects: ① hydration solutions with different ionic concentrations (deionized water, 0.05mol/l CaCl2 solution and 1: 1 ethanol solution by volume); ② different types of hydration solutions (0.05mol/l CaCl2 solution and 1: 1 ethanol solution by volume); ③ different hydration normal stress conditions (pressureless hydration condition, 5kPa hydration condition and 10kPa hydration condition).

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
