Due to the higher bending strength, excellent toughness, and permeability, it was used as the basal cushion layer of geomembrane in surface barrier
of high rock-fill dam on thick pervious foundation .
Limit state definition of reinforced concrete structures with protective surface barriers
The [alpha] particles and tritons produced by the [.sup.6]Li(n, t)[.sup.4]He reactions were detected by four surface barrier
detectors, each with a well-defined and carefully measured solid angle.
We are going to use surface barrier
detectors made from pure silicon.
The proton detector will consist of a thin, cooled silicon surface barrier
detector and front-end preamp package surrounded by a hemispherical wire grid at -25 kV to accelerate the protons.
