| 2. | A diffusion mechanism whereby atomic motion is from interstitial site to interstitial site 晶体扩散机制的一种。间隙原子由一个间隙位置迁移至邻近的间隙位置所构成的扩散。 |
| 3. | The diffusion mechanism wherein net atomic migration is from lattice site to an adjacent vacancy 一种扩散机制,这时候原子的净迁移过程是从晶格结点位置移动到邻近的空位中。 |
| 4. | Based on studying element motion theory and geological , this paper studied the diffusion mechanism of gas in strata 在分子运动学理论及地质条件研究的基础上,研究了天然气在地下扩散机制。 |
| 5. | Abstract : the diffusion mechanism for the diffusion migration with electromigration together was discussed . the differential equations for describing the diffusion mechanism were obtained 文摘:讨论了扩散迁移与电致迁移共同作用时的扩散机制,导出了可描述这一过程的微分方程 |
| 6. | In succession , the author specially studies the diffusion mechanism in the course of currency crisis evolution , and puts forward several hidden currency crisis contagion channel suitable to the opening level and developing condition of the finance market of china 接着,针对当代货币危机的特点? ?传染性,专门研究货币危机演进中的扩散机制,并提出适合我国金融市场开放程度和发育状况的危机传染潜在渠道。 |
| 7. | Reacting temperature had much effect on product purity ; while reacting time above 1150c had little effect on microstructure ; the salt content had some effect on microstructure , it was appropriate that the proportion of the salt and the raw materials was 1 : 1 . the growth process of batio3 powders was controlled by diffusion mechanism . in the present paper , the synthesis of srti03 proceeded through two steps 合成温度对产物纯度有很大影响;在一定温度下保温时间对产物纯度影响不大;随着反应温度的升高和反应时间的延长,粉体颗粒的尺寸有所增大,但增加不大;盐的含量对粉体形态有一定影响,在盐与反应物的质量比为1左右比较合适。 |
| 8. | The author analyzes urban spatial form ' s random quality and rise and fall phenomenon , and then calculates its fractional dimension value . the author also studies the evolution mechanisms exist in xi ' an urban spatial structure ' s evolution which are self - organization and organization mechanism , agglomeration and diffusion mechanism , ecological mechanism 分析探讨西安城市空间结构演化中的自组织与他组织、集聚与扩散、多系统协同等演替机制,提出西安未来城市空间结构的发展具有可持续化、生态化、信息化、注重历史文脉继承与保护、开放性与区域化等趋势。 |
| 9. | As to epoxy / toa / org - mmt system , the reaction order was 0 . 9 and active energy was 66kj / mol by kissinger method ; and a similar result was obtained by ozawa method . the curing reaction was controlled clearly by diffusion mechanism in the later stage of curing reaction without addition of org - mmt , which leads to the increment of active energy with extend of curing ; as to the curing system with addition of org - mmt , the value of active energy was always kept the same level , which can be explained by the catalytic function of amine salt inserted in the galleries of org - mmt 对于环氧桐油酸酐有机蒙脱土固化体系用kissinger方法看到固化体系的反应级数均为0 . 9左右,表观活化能值为66kj mol ; ozawa方法的处理结果与之近似,但从ozawa方法可以看到未加入有机蒙脱土的体系在反应后期固化反应明显受扩散控制,表现为活化能随固化程度的增加而增加;而加入有机蒙脱土的体系,其表观活化能则自始至终表现的较为均匀。 |
