激活理论 meaning in Chinese
activation theory
Examples
- The apparent activation volume calculated by the model is about 2500a3 , which was ten times larger than that of usual amorphous alloy and was at the same range of the amorphous polymer . the model shows the main deformation mechanism of nanocrystalline ag is grain boundary sliding , which in some extent declares the similar forms of equation with amorphous alloys . with the ananlysis to the hrem of nanocrystalline ag , the discrepancy of the apparent activation volume between the nanocrystalline ag and amorphous alloys is interpreted by the loss of atoms participating in grain boundary sliding without enough reconstruction by the movement of atoms under the low temperature
运用晶界滑移的热激活理论对压缩实验结果进行了数值拟合，拟合曲线与实验数据符合很好，得到了晶界滑移的表观激活体积(热激活基本单位体积与局域瞬态应变的乘积) ，约为2500a ~ 3 ，先当于几十个原子体积大小的瞬态变化，约为非晶合金的10倍以上，与非晶高聚物的表观激活体积相当。 - For historical city , the validity protection surely is very necessary and have the realistic meaning , but how to make use of this a rare and precious resources advantage , and play the role of its special function , and improve the quality of livelihood , and avoid breakage and ruin . eight parts are included in this thesis . in part one , author make definitude the particular concept for the tourism development of historical city , expound some problems at present , discuss its development basic theories
第一部分主要是在以往国内外专家、学者对名城相关研究的基础上，从本文论述的角度界定了名城旅游开发的特殊概念，同时总结了当前名城旅游开发研究的现状及意义，最后较为系统的论述了历史文化名城旅游开发的几个理论出发点：旅游资源泛化思维、持续发展和文化传承理念、旧城激活理论、体验经济理论，为历史文化名城进行旅游开发提供科学的理论依据。
