turbostratic meaning in Chinese
湍层的
Examples
- Characters of the pyrolysis chars and residual carbons such as reactivity , turbostratic carbon structure and specific surface area have been examined by thermal gravimetric analysis , powder x - ray diffraction and mercury intrusion methods respectively . catalytic effect of minerals has been identified
高温下不同煤质焦碳结构趋于一致和矿物质催化作用的失去在一定程度上证明了假定活化能不随煤质变化的煤焦燃烧反应动力学通用规律的合理性。 - In order to improve the adherence of the film to the substrate and the repeatability of synthesis , we invent a three - step approach , which comprised the steps of turbostratic boron nitride ( tbn ) turning into rhombohedral boron nitride ( rbn ) as the first , rbn turning into cbn as the second and deposition as the last
基于对bn薄膜相结构的分析和优化的沉积条件,制备出立方相含量高达95 %的cbn薄膜。为了改善制备的可重复性和粘附性,提出了三步沉积方法,即将成核过程分成tbn转化为rbn和rbn转化成cbn的两步,加上之后的沉积过程。 - With the increase of temperature , chars from low rank coals deactivate quickly and significantly . through a strict and systematic analysis , char deactivation has been found to be due to the combined effect of the ordering of turbostratic carbon structure and the loss of catalytic effect of minerals during pyrolysis or combustion process
但当煤颗粒在中低温下燃烧时,由不同煤质形成的焦碳的乱层碳结构的差别较大,煤中的矿物质所起的催化作用可能很不一样,因而导致不同煤质的焦碳燃烧反应活化能有较大差别。 - The combustion conditions in a circulating fluidized bed ( cfb ) boiler are much different from a pulverized coal firing ( pf ) boiler . however , this dissertation has confirmed that coal char in cfb boiler will also experience reactivity loss and ordering of turbostratic carbon structure , which have been reported by many researchers whose work were mainly restricted to pf conditions
本文通过获得在cfb燃烧条件下热解和燃烧过程中的焦碳,对其反应性、乱层碳结构、矿物质催化作用和比表面积等进行了系统研究,指出cfb锅炉和煤粉炉同样存在焦碳乱层碳结构有序化和焦碳反应性下降(失活)现象,并全面分析了焦碳失活的机理。 - With the increasing of temperature , the mineral catalytic effect is losing quickly , and completely lost above 1200 ( c , which agrees with the results by other researchers . the study of residual carbons from cfb fly ashes and its comparison with pyrolysis chars have confirmed both deactivation and ordering of turbostratic carbon
本文建立了一个简单的焦碳反应性衰减模型,将此模型用在一个一维的cfb基本模型中,给合在一个小型热态cfb实验台的燃烧实验,考察了模型对飞灰含碳量的预测受焦碳失活的影响。
