<正>采用分子动力学方法分析一维FPU模型的热传导。以研究低维系统的热传导是否遵循Fourier热传导定律。结果表明：只有在两端温度较高的情况下，其温度才能呈现梯度分布，且热导率与链长呈指数关系；而如果两端温度很低，则不能形成梯度分布。

Grown for its fine timber and as a medicinal plant, Cyclocarya paliurus (family Juglandaceae) is native to China and is the sole species in its genus. On the basis of introducing the geographical distribution, morphological and growth characters of C. paliurus, research progresses on seed dormancy and its breaking, seedling propagation techniques, plantation silviculture, chemical compositions, medical use of C. paliurus were summarized in this paper. Also some suggestions on resources silviculture of C. paliurus and their new product development were proposed for future research.
