| 6. | The essential effects of grain boundaries on signal transmission is that the resistivity from grain boundary is much more than that from grain inside , and the evidence of grain boundaries on signal transmission is resistance , capacitance and inductance characteristic of grain boundaries
晶界的电阻率大于晶界两侧晶粒的电阻率是晶界影响线材传输性能的本质，晶界的电阻、电容以及电感特性是晶界对线材传输性能影响的具体表现形式。 |
| 7. | Both the qualitative pictures and the quamitative data , such as grain growth kinetics exponent ( aboul 1 . 8 in the early stage and 5 . 5 in the late stage of grain growth ) and the values of fractal dimension ( about 2 . 6 in the early stage and 2 . 2 in the late stage of grain growth ) , show that the simulation work is in good agreement with experimental results reported
不论是从定性的仿真图形分析还是从定量的晶粒生长动力学指数k (生长初期约为1 . 8 ，生长后期约为5 . 5 )或是晶界的分维值d (生长初期约为2 . 6 ，生长后期约为2 . 2 ) ，都说明我们的仿真工作与其它报导的实验结果互相一致。 |
| 8. | The surface of ce02 - ti02 films were very smooth and difficulty to crystallization . the ceo2 - tio2 complex films were nanocrystalline microstructure or microcrystalline even if to heat the substrates or to anneal the films . the ceo2 and tio2 nanocrystalline were not easy congregate and bigger because of heterogeneity interface disturb and have many defect
组成ceo _ 2 - tio _ 2混合薄膜颗粒粒径在纳米尺度范围3 ? 50nm ，与纯ceo _ 2 、 tio _ 2薄膜相比，具有更小的表面粗糙度和更难结晶，这是由于异质材料晶界的相互干扰，使同质颗粒之间难于聚集而结晶长大，薄膜处于纳米晶或雏晶态，即使加热基片或薄膜进行热处理也无明显变化。 |
| 9. | The thesis mainly studies the assistance model of the structure evolution when the hsla steel is heated , works out the mathematic expression of the grain boundary in the process of interaction between grain boundary and second - phase particle , and develops a new physical model when grain are pinned by the second - phase participle
