中华文明生命力传播力及其与世界其他文明的交流互鉴

中华文化在几千年历史进程中锤炼出“融同化异”的坚韧特性,它以道为统,以儒为基,以天人合一为根本理念,以大一统为政治文化主流,以爱国主义为核心价值,以求变革新为鲜明品格,以天下大同为崇高理想。中华文明不仅吸收外来文化的精华,滋补本民族文化血脉,还在与外来文化交流中,传递出独有的“智慧之光”。正是在与不同文明的交流互鉴、融合会通中,中华文明创造了延绵五千多年从未中断的辉煌奇迹,塑造了植根于中华民族血脉深处的文化基因,为人类文明事业做出不朽功绩,为我们在新时代坚定文化自信、历史自信,探索促进人类文明交流的内在驱动力,深化世界文明交流互鉴,构建人类命运共同体,提供了有益而丰厚的历史滋养。

Melting Heat in Radiative Flow of Carbon Nanotubes with Homogeneous-Heterogeneous Reactions

The present article provides mathematical modeling for melting heat and thermal radiation in stagnationpoint flow of carbon nanotubes towards a nonlinear stretchable surface of variable thickness. The process of homogeneousheterogeneous reactions is considered. Diffusion coefficients are considered equal for both reactant and autocatalyst.Water and gasoline oil are taken as base fluids. The conversion of partial differential system to ordinary differential system is done by suitable transformations. Optimal homotopy technique is employed for the solutions development of velocity, temperature, concentration, skin friction and local Nusselt number. Graphical results for various values of pertinent parameters are displayed and discussed. Our results indicate that the skin friction coefficient and local Nusselt number are enhanced for larger values of nanoparticles volume fraction.
