Results indicate that the samples are comprised of slate - like grains growing up in different directions , and that grain size and pore play a domain role in electrical conductivity and thermal conductivity besides seebeck coefficient 结果显示烧结样品由不同取向的片状颗粒组成，颗粒大小以及颗粒间的气孔数量对样品的电导率和热导率有显著影响，对seebeck系数影响不大。
Experimental study is performed on the mist cooling of heated high temperature surface covered by a sand layer to investigate the effects of both sand size and thickness of sand layer on heat transfer charateristics in order to enhance heat transfer of film boiling region 摘要研究了高温金属面上覆盖砂层后的喷雾冷却换热特性，测试了砂粒颗粒大小和砂层厚度对换热特性的影响。
The hybrid material was characterized by ft - ir , fluorescence , xps , tg - dta , and dmta . the morphology of the hybrid material was observed by tem . it was showed that sno2 nanoparticles were in the shape of sphere or tube and some tubes even bifurcated ( 2 )表面活性剂dbs能提高纳米sno _ 2在聚合漆酚中的稳定性，对pus sno _ 2杂化材料的形成起了重要作用，使其颗粒大小在纳米范围内。
It is therefore important to develop and validate standard methods , both for the characterization of dietary fibre ( quantification , particle size , water binding , fermentability , solubility ) and for the evaluation of its clinical . efficacy 因此，确定一种标准的研究方法很重要，它应该规定用于研究的膳食纤维的特性(如剂量、颗粒大小、水结合度、可酵解度、溶解度等)和临床疗效的评价方法。
Based on one dimension flow theory and lagrange method , the correlation of speeding rate of particles under gas flow drag with the size of particles and the length of laval nozzle used for the gas and solid two - phase separation test apparatus was studied 摘要采用一元流动理论和拉格朗日方法，研究了用于气、固两相分离试验装置的缩放喷管内，被气流拖曳的颗粒加速率与颗粒大小和缩放喷管长度的关系。
Amorphous can be obtained at certain composition range using ball milling . the size of the amorphous particles decreases with the lengthening of milling time , and reaches several nanometers . experiment also shows that the mixture powder is well ferromagnetic 实验发现，在一定成分范围内通过球磨可以获得非晶，非晶粉末颗粒大小随球磨时间的延长而减小，最终达到几个纳米；同时发现，该混合粉末具有良好的铁磁性。
During the trenching procedure , until concrete casting is taken , it is very crucial to maintain the stability of the trench wall , which relatives closely to geologic conditions , particle size , groundwater state , trenching skills and so on 槽壁的稳定与地质结构、颗粒大小、地下水情况、施工工艺等因素有着密切的关系，泥浆固壁是保证槽孔稳定最有效的方法。泥浆固壁的机理和槽壁的稳定关系分析是一个非常复杂的问题。
Nor does metal roller milling exhaust the list of important innovations in grain processing , for we also see continuous improvements in grain - separation technology , faster analysis of mill batches for protein content among other things , and greater control over flour particle size and uniformity 金属磙筒只是谷物加工方面众多重要的发明之一。我们还看到：谷物去壳技术的不断改进，批量碾磨中蛋白含量的更快速的鉴定，还有对粉状颗粒大小和均匀性的更有效的控制。
Finally build the foundation to prepare the composites of structure and m - type ferrite with structure and function properties . the constituent phases , microstructure and crystal dimension and crystal coalescence , mechanical properties , magnetic properties of the composites were investigated by means of x - ray diffraction ( xrd ) , scanning electron micrograp h ( sem ) and transmission electron micrograph ( tem ) , mechanical testing instrument , vibrating sample magnetometer ( vsm ) respectively 采用xrd技术鉴定复合材料的物相，利用sem ， tem来分析srfe12o19及其复合材料的结构形貌，颗粒大小及结合情况，使用伺服材料实验机、洛氏硬度计及振动样品磁强计( vsm )测试了复合陶瓷的抗弯强度、硬度及其磁性能，并探讨它们之间关系。
