1. Assessment of Experimental Data.All the experimental data in the present study throughout the term of project were rearranged and were reassessed. Special cares were given to the relationship between temperature field and propagation of vibration within the micro-structural suspensions and slurries of micro-powders.2. Simulations and analysis.The simulations were performed continuously in order to store the simulation data which should be analyzed before the total report.3. Total assessment and analysis of the research results and reportTotal discussions were carried out on all the experimental data on the relationship between temperature field and propagation of vibration within the micro-structural suspensions and slurries of micro-powders in the present study throughout the term of project. And the final report in which the heat transfer mechanism were clarified and the effective method for active control of heat transport within a micro-slurries was madeMicro structural slurries such as suspensions were suffered a change of inner structure due to its inner share stress by a small vibration. The change is affected by a variety of conditions such as micro-particles in a suspension and inner connection condition among the particles. Furthermore, it is also found that the change of inner structure of such materials also suffers the change of its thermal transport properties. The results of the present study gives a possibility of controlling heat transfer using a small vibration of materials.

1.实验数据的评估：本研究中的所有实验数据在整个项目期间被重新整理和重新评估。重点研究了微结构悬浮液和微粉末浆料中温度场与振动传播的关系。模拟与分析：模拟是连续进行的，以存储模拟数据，以便在总报告之前进行分析.对研究结果和报告进行了全面的评价和分析，对本研究中的微结构悬浮液和微粉浆料中温度场与振动传播关系的全部实验数据进行了全面的讨论。在此基础上，提出了微浆体内部传热主动控制的有效方法。微结构浆料如悬浮液，在微小振动下，由于内部应力的作用，其内部结构发生变化。这种变化受悬浮液中的微颗粒以及颗粒之间的内部连接状况等多种条件的影响。此外，还发现这种材料内部结构的变化也会影响其热输运性质的变化。本研究的结果给出了一种可能性，控制传热使用的材料的小振动。
