Sub - micron grades with extremely high wear resistance for abrasive materials such as laminated chip board , hard wood , etc 是适合于研磨料（比如电木板、硬木）的加工，具有极高的耐磨性，晶粒度为亚微米级的牌号。
The resistance of the nano - bulk al increases with the increase of the temperature and decrease with the increase of the grain size 在我们测定的纳米金属铝材料中，电阻率随温度的升高而增大、随晶粒度尺寸增大而减小。
The structure size of mn wire after continuously imduction quenching is about 5 m grain size : 12 . according to national standard zbj6001 - 88 microscopic inspection of Mn钢丝连续感应加热淬火组织尺寸约为5m晶粒度12级。
The rule is that with the increasing of yttrium ' s contents , the granularity , the circular - degree and the distributing - leveling of the quasicrystals are improved 其规律为，伴随y含量的增加，准晶体的晶粒度、圆整度和分布均匀化程度均有提高。
Super hard sub micron grade with 3 % binder and an outstanding hardness of 2000 hv30 . excellent resistance against wear , not suitable for metal cutting operations 加入了3 %的粘合剂，是超硬的牌号，晶粒度为亚微米级，硬度高达2000hv30 。极好的耐磨性，不适合金属切削操作。
The x - ray diffraction analysis shows films prepared by rf and ve have scattering peaks , however the peak intensity of pure cdte films prepared by css method is higher than ahead both 而且用css方法制备的cdte薄膜晶粒度大，薄膜晶形好。利用近距离升华技术在glass / ito基片上先后沉积cds 、 cdte膜，保证cds膜的厚度< 2000
This comparison research including grain size , pearlite content , ferrtie microhardness , banded structure and chemical composition was carried out on hsla steel with same thickness and different mechanical properties 摘要通过对二组同一厚度、力学性能尤其是屈服强度有明显差异的低合金钢板进行晶粒度、珠光体含量、铁素体显微硬度、带状组织以及化学成分对比试验。
Comparing with other similar study , the advantage of the added function here is that the redeveloped deform3d can not only predict the average grain size , but also analyse the generation and development of the duplex grain during hot forging 与其它同类研究工作相比，本文所开发的微观组织模拟功能不仅能预测平均晶粒度的变化，还能用于分析热锻过程中混晶缺陷的发生与发展过程。
The experimental powder samples were heated from room temperature to 600 、 800 、 900 、 1000 、 1100 and 1300 respectively for sintering , and then were analysed by means of xrd to investigate the crystal granularity of the powder samples sintered at different temperature 对粉体分别进行从室温加热到600 、 800 、 900 、 1000 、 1100和1300的?烧处理，对?烧样品进行了x射线衍射分析，研究了不同?烧温度下，纳米氧化铝的晶粒度。
