A mathematical model is formulated making it possible to determine temperature and stresses in a solidifying ingot and in the wall of a mold. It is established that an ingot is most relieved with heating of the mold wall and rounding of the corners of the ingot cross section.Translated from Teoreticheskaya i Prikladnaya Mekhanika, No. 18, pp. 123–127, 1987. 相似文献

Three-component condensation of lower aliphatic aldehydes (C1-C3) with arylamines and cyclopentadiene (the Povarov reaction) gave 3a,4,5,9b-tetrahydro-3H-cyclopenta[c]-quinolines. Ozonization of their N-trifluoroacetyl derivatives afforded the corresponding ozonides. Cyclocondensation of 4-fluoroaniline with formaldehyde and cyclopentadiene gave earlier unknown 2-fluoro-3b,6,6a,7,9,9a,10,12a-octahydrobenzo[i,j]dicyclopenta[b,g]quinolizine. 相似文献
