扩散距离 meaning in Chinese
diffuse field distance
diffusion distance
diffusion length
dispersal distance
Examples
- For the powder milled to amorphous state , because of its very fine structure , it is easy to occur phase transformation and has good size stability when sintered
研磨到非晶态的粉末由于元素达到原子尺度混合，大大缩短了扩散距离，不仅易于发生固态相变，而且烧结体尺寸稳定性好。 - In the interdiffused layer the diffused length of nb - 1zr alloy elements is longer than that of stainless steel elements , the diffused length of ni is the longest . there are a mass of needle shape precipitated phases in the interdiffused layers formed by 1300 annealing , which are determined to be a metastable cph - ( nb , ni ) by sadp method
通过对真空退火形成的互扩散层的金相和成分分布分析可以发现，不锈钢元素中ni元素在nb合金中的扩散速度最快， fe 、 cr元素次之；而nb元素向不锈钢中的扩散距离要比不锈钢元素向nb合金中的扩散要深得多。 - Abstract : the article introduces cement slurry rheological characteristics and the method of determining the main parameters for cement slurry rheological characteristics , and analyses the difference between the rotation type and funnel type of viscometers in measuring plastic viscosity and apparent viscosity of cement slurry , and then the limitation of the funnel type of viscometer is described . the difference between rigidity and yield value is pointed out . finally through analysis of cement slurry rheological characteristics , the cement slurry filling mechanism is proposed , and the main factors affecting cement slurry are studied
文摘:介绍塑性流体水泥浆的流变性及确定水泥浆主要流变参数的一般方法；分析旋转式粘度计与漏斗式粘度计在测定水泥浆塑性粘度、表观粘度时的区别，说明漏斗式粘度计在使用上的局限性；针对粘聚力（动切力）的测定进行分析，认为粘聚力与动切力为不同的概念.通过对水泥浆流变性分析，提出水泥浆充填机理，并对影响水泥浆扩散的主要因素，即粘度影响水泥浆在节理裂隙中向前扩散的速度，动切力限制水泥浆扩散距离作了说明
