| 6. | The start up and linear growth process of the microwave within the foldaway - concentric cylindrical resonant cavity are analyzed based on the one dimensional model firstly , then a 2 . 5 - d pic code is employed to study the nonlinear interaction 由于电子束在同一个腔内受到了100深度的调制,可以直接加微波提取腔进行微波提取。然后用二维半pic程序对它进行数值模拟研究。 |
| 7. | When the linear growth rate of entities g reduces , the value of vc reduces too . however , the values of avrami exponent and s are hardly affected by the value of g . the conclusions are approved by the data from hspom experiment 晶体线生长速率g减小,对avrami指数n值和_ s值基本没有影响:而g减小, v _ c值也会减小;热台偏光显微镜实验以peo为样品,也证实了这些结果。 |

| 9. | A new model was presented in a three dimensional geographic coodinate system to describe the linear growth of r - t instability so that the effects of magnetic inclination and declination were taken into accont . it is an generalization of former theories from equatorial to mid - latitude regions . from this model one can see the influence of magnetic strength , inclination and declination . due to the magnetic effects , the occurrence rate of the instability is not symmetric in longitudes even at the magnetic equator . some occurrence peaks or valleys will appear in certain places around the world 从三维地理坐标系出发建立模型,考虑了地磁倾角和偏角的影响,研究spread - f现象的全球分布特点,是对以前的研究从赤道地区向中低纬度地区的推广。从该三维模型中可以看到地磁场的大小和位型的影响包括磁倾角和磁偏角的效应。由于地磁位型的不同,发生率的分布并不具有经度对称性,即使在磁赤道附近也如此。 |
| 10. | Furthermore , referring to the literature and considering the specific experimental conditions given by the research , expression of the change of feed rate with time is presented , to obtain the linear growth of the diameter of pre - sintered glass beads , thus the distribution of beads size is relatively well controlled and raw material is spared in some extent . eventually , during the experiment discrete change of feed rate is implemented , and the practical changes of average diameter are plotted , then the results are compared with the theoretical calculated data 另外,本文通过对造粒技术、烧结过程的大员文献调研,结合本研究的具体情况,通过控制进料速率呈连续性变化,基本实现了烧结前球坯直径的线性生长变化,从而更有利于实际生产中的产品粒度控制以及做到节约用料,并在试验操作中以离散型进料速率变化来加以比较验证。 |
