The main reason of the above mentioned results is attributed to different diffusion mechanisms which are caused by different element natures in the alloy system.
产生这种现象的原因主要是合金体系中元素性质不同，使得反应合成制备中元素的扩散机制不同所造成的。
The main important work of this paper: (1). Deeply studied data diffusion mechanisms and some basic ideas of relative routing algorithms for wireless sensor network.
本文主要工作如下：(1)深入研究了传感器网络的数据扩散机制及其相关路由算法理论基础。
The fire was modeled by the mixture fraction combustion method with chemical reaction mechanisms neglected. Laminar diffusion flame theory with one-step irreversible fast reactions is assumed.
对火的描述采用混合分数燃烧模型，模型中忽略燃烧过程中的反应机理，应用了层流扩散火焰理论和单步不可逆快速反应假定。
