中文摘要：

热传导上的研究到目前为止主要集中于常规系统例如一个维(1D ) 并且二维(2D ) 原子定期被连接的格子和原子的温度同类地被散布。然而，象 nanotube/nanowire 网络那样的现实主义的系统不常规却不同类地组织，并且他们的热传导仍然保持大部分未知。我们在场到在网络结构怎么影响热传导系数的如此的物理网络和焦点的学习热传导的伪物理的网络的一个模型。在这个模型，我们第一次在以前的研究把每个连接看作原子的 1D 链而不是一个弹簧。我们发现那与连接不同到在网络的连接，与在常规 1D 或 2D 格子的一样的常数相对照。而且为每个特定的连接，我们在场显示出怎么在它的二上取决于它的连接长度和温度的一个公式结束。在物理网络的热传导不是 1D 和 2D 格子，但是严重的直接扩展的这些调查结果表演由网络结构影响了。

英文摘要：

Studies on heat conduction are so far mainly focused on regular systems such as the one-dimensional（1D） and twodimensional（2D） lattices where atoms are regularly connected and temperatures of atoms are homogeneously distributed.However, realistic systems such as the nanotube/nanowire networks are not regular but heterogeneously structured, and their heat conduction remains largely unknown. We present a model of quasi-physical networks to study heat conduction in such physical networks and focus on how the network structure influences the heat conduction coefficient κ. In this model,we for the first time consider each link as a 1D chain of atoms instead of a spring in the previous studies. We find that κ is different from link to link in the network, in contrast to the same constant in a regular 1D or 2D lattice. Moreover, for each specific link, we present a formula to show how κ depends on both its link length and the temperatures on its two ends.These findings show that the heat conduction in physical networks is not a straightforward extension of 1D and 2D lattices but seriously influenced by the network structure.
