(a) Using the expansion of ln(1+x) given in Eq. (2.41), show that, for sufficiently large n, (i)1n+lnn-1n<0,(ii)1n-lnn+1n>0. (b) Use these inequalities to show that the limit defining the Euler- Mascheroni constant, Eq. (2.13), is finite.2.5...

(7)V(T)=Vref[1+α¯(T−Tref)]. Figure1shows examples of thermal expansion data of chromium atambient pressureand temperatures up to the melting temperature. The results ofγ-ray absorption measurements (Stankus 1993) are in good agreement with x-raypowder diffractiondata (Dubrovinskaiaet ...
Anomalous thermal expansion behaviour of Ln 来自 ResearchGate 喜欢 0 阅读量: 19 摘要: Based on a consideration of the crystal structures of well-known negative thermal expansion (NTE) materials, ZrV2O7 and ZrW2O8, we have identified a new series of tetramolybdates, Ln2Mo4O15 (Ln = Y,...
