体扩散 meaning in English
volume diffusion
Examples
- Vacancy - solute atom complexes diffusion and non - equilibrium segregation in alloy steels
溶质原子复合体扩散与非平衡偏聚 - Therefore , the accidental poisonous gas diffusion is an important content in safety assessment
笔者通过梯度输送理论，建立了无风条件下气体扩散的动态模型。 - While keeping a close eye on proliferation activities by traditional nation actors , the us included international organizations , transnational crime organizations and terrorist groups into its target . what is more , these newly - founded targets have taken an ever - increasingly important role in the whole non - proliferation system
除此之外,在继续关注传统国家行为体扩散之余,美国也将防扩散政策的针对目标扩大到了国际组织、跨国犯罪集团、恐怖主义团体等非国家行为体,且后者在整个防扩散体系中的重要性与日俱增。 - In the thesis , we proposed a random lattice model of mea the lattice model randomly occupied by three kinds of particles , pt / c , nafion and ptfe ( poly - tetra - fluoro - ethylene ) , was generated on a computer by the means of monte carlo method . it was supposed that current was only produced on those catalysts which have not only channels of electrons via carbon but also have channels of proton via nafion . the purpose of the work , in a word , is to find how many catalysts , pt / c , with such a two - types channels
本文首先建立了质子交换膜燃料电池的膜电极的随机方格子模型，在电极模型各格点位置用montecarlo方法生成随机分布的电极粒子、 nafion粒子和聚四氟乙烯团粒，认为只有那些既有质子传输通道，又有连续的电子通道和气体扩散通道的胞元才产生有效的电流，而其余胞元不产生电流，把电极的输出电流转化成一个概率事件。
