The nature of the propagation of a thermal wave produced by a powerful explosion was described in a number of papers, for example, [1–6]. It was shown by a numerical method [4] that a shock wave is present together with the thermal wave. In this paper, the effect of a homothermal shock wave on heat propagation is evaluated by an approximate method. 相似文献

When two coherent waves propagate in a transparent medium with cubic nonlinearity, a nonclassical state appears which is characterized by the quantum correlation of the waves. On the basis of exact solutions to the problem, it was found that such states lead to violation of the separability criterion for continuous variables. 相似文献

It is shown in [1] that the internal shock wave has a significant effect on the conditions of thermal-wave propagation. In this paper, the effect of the mass Mo released by the thermal-wave propagation is estimated by a method similar to that in [1].Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 1, pp. 52–55, January–February, 1978. 相似文献

A number of cis-9-propenylcarbazoles were synthesized in good yields by isomerization of 9-allylcarbazoles by the action of
tert-BuOK in dimethyl sulfoxide. It was established that cis-9-propenylcarbazole is less thermodynamically stable than its
trans isomer. It was shown by13C NMR, UV, and IR spectroscopy that the effect of p-π conjugation in cis-9-propenylcarbazole decreases as compared with the
trans isomer as a result of the noncoplanarity of the C=C bond and the carbazole ring.
