Finite element method for generalized piezothermoelastic problems

AbstractThis paper is concerned with the generalized piezothermoelastic problems using finite element method (FEM). The governing equations are solved directly in time-domain to minimize precision losses caused during Laplace transformation. The results reveal that the heat wave propagating in medium at a finite speed can be described. Breakdown of a linear temperature drop at the heat wave front which cannot be described by Fourier’s law is observed. Furthermore, the high concentration of stress and electric intensity at the heat wave front due to the high temperature gradient has been newly found

Research on the Impact of Agricultural Financial Support on Agricultural Carbon Compensation Rate

Based on the consideration of the dual attributes of agricultural carbon emission and carbon sink, this study measures the agricultural carbon compensation rate (ACCR) of 31 provinces in China from 2006 to 2019, the impact of agricultural financial support on ACCR and its transmission mechanism are empirically analyzed using a spatial econometric model and intermediary effect model. The results show that: (1) a significant spatial correlation between agricultural financial support and ACCR; (2) increased agricultural financial support is conducive to the improvement of ACCR; (3) agricultural financial support has the most significant effect on the ACCR in the eastern region; (4) the effect of agricultural financial support on ACCR has a spatial spillover effect but is not significant; (5) agricultural technological progress is the intermediary variable that agricultural financial support affecting ACCR. Therefore, it is suggested to promote agricultural emission reduction through collaboration, innovative financial support mechanisms, implementation of differentiated financial support strategies, exerting the radiation effect of financial support to agriculture, and pushing up the level of agricultural mechanization
