We have developed a reconstruction algorithm for non-contact measurement of temperature and absorption of combustion gas distributed in a flame. To get accurate temperature distribution of the combustion gas, the absorption of the gas must be known. We achieve this by obtaining the projections of thermal radiation from the flame and an external radiation(More)

Sliding behaviors of Σ9(221) grain boundary bicrystals have been investigated in pure metals (Al, Ag, Au, Cu, Pt and Co) and in segregated metals (Cu segregated by Al, Ag, Au, Pt and Co) by molecular dynamics simulations and first-principles calculations. The grain boundary energy, the atomic size and the electronegativity of the segregated elements were(More)
