At high temporature between 700℃ to 850℃,a protective film of Al2O3 forms at the sur-face of Fe3Al intermetallics, so that Fe3Al is more oxidation resistance than stainless steels,Additionof 2%Cr to Fe3Al results in the increase of oxidation rate at the initial stage of oxidation,In melted sulphates or smoke of high pressure boileres,Fe3Al has higher corrosion resistance than the superalloyGH132.
We also describe natural ways of discretizing those wavelet transforms, or equivalently to obtain atomic decompositions and Banach frames for the corresponding coorbit spaces.
Emission and absorption band spectra of sulphur dioxide were studied in the region between 2600 to 2000 A.U. A new system of emission bands (about 150 bands) was found. When these bands were compared with the absorption bands and Mr. Lotmar's fluorescent bands, coincidences were found which amount to 40% and 50% of the total number of absorption and fluorescent bands respectively. These agreements and the very different structure as compared with the SO bands recorded on the same plate made it very probable...
Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determi...
The general feature of the Stark effect of the alkali atoms, the linear effect observed by Ny and Choong for the lines near the series limit of Cs and Rb, the decomposition of the m2S-n2D lines of Na into n-2 equidistant components, and the appearence of m2S-n2S series in a polarization are discussed on the basis of the perturbation theory.
