和这有联系吗？？ Kohlrausch, F.. On the stationary temperature condition in an electrically heated conductor. Annalen der Physik (Weinheim, Germany) (1900), 1 132. Abstract A new method is proposed for the purpose of studying the flow of heat in a long cylindrical metal rod heated by the passage of an electric current, and insulated thermally except at the two ends, which are maintained at a constant temperature. The position of the isothermal and isopotential surfaces are then transverse to the length of the rod. Only the theory of the method is treated of in the present paper, which should be taken in connection with the measurements of Jaeger and Disselhorst, who have applied the method to the case of several metals and alloys. The author shows that the steady temperature condition does not depend on thermal or electrical conductivity alone, but on the ratio of the two. The pure metals form a group giving the smallest value of this ratio and at the same time the highest temperature. |
