where l is the length of the specimen, t is the temperature, and p is the pressure. For each solid there is a Debye characteristic temperature &THgr;, below which αl is strongly dependent upon temperature and above which αl is practically constant. Many common substances are near or ...
whereMλis the spectral radiant emittance given in Wcm−2per unit wavelength. ThusMλis the radiated power density per wavelength,λ. Further,Tis the absolute temperature (K),Cl=3.7418×10−12Wcm2andC2=1.4388cmK. These coefficients are expressed in terms of fundamental physical constants asC...

11.6). This incidence evinces a chemical interaction between these substances due to high temperature. The polarity of ketoconazole coupled with high temperature may result in the disappearance of the ketoconazole peak (Tiţa et al., 2011). Simultaneously, visible differences were observed in a 1:...
substances of high heat capacity and moderate thermal conductivity: stone, adobe, rammed earth, brick, water, concrete, and more recently, phase-change materials. While broadly similar, these substances absorb and release heat in unique patterns characteristic of their mineralogies, densities, fluid...
Anomalous thermal expansion of Sm/sub 2/Fe/sub 15/Si/sub 2/ was observed below Curie temperature by high-temperature X-ray diffraction experiments.>关键词: Curie temperature X-ray diffraction examination of materials...
If A(z) remains constant or segmented constants with depth, the solution changes to a simplified form as(10)T(z)=T0+q0zK−A0z22Kwhere, T(z) is the lithospheric temperature (°C) at depth of z (km). However, the thermal conductivity and heat production rate are not constant ...
The lattice constants, space groups and linear coefficients of thermal expansion in the various axial directions were determined for the selenates and chromates of lead, strontium and barium. The lead and strontium compounds are monoclinic, while barium Chromate and selenate are orthorhombic (barite ...
