| 1. | Effects of crystal size of zn zsm 5 and pretreatment conditions on the aromatization of propane 5分子筛晶粒大小和预处理条件对丙烷芳构化性能的影响 |
| 2. | Derived from a with small crystal size . the grain is composed of fine crystalline blocks with high streath 棕刚玉的派生品种,磨料由微小晶体构成,颜色与棕刚玉相似,强度高。 |
| 3. | The presence of montmorillonite makes the crystal size diminish markedly and makes the integrality of crystal reduce . 4 加入蒙脱土后,尼龙66的晶体尺寸明显减小,结晶的完整性下降。 |
| 4. | ( 3 ) after modification , the crystallinity and orientation of uhmwpe fiber has no obvious change , but the crystal size decreases greatly 纳米粒子的加入对纤维的取向度、结晶度基本没有影响,而纤维的晶粒尺寸大大降低。 |
| 5. | Especially when 1 . 2wt % vc is added , the effect of inhibition is most obvious . at this time the crystal size is about 200nm - 300nm . and the trs comes to be 1293 mpa 尤其是当添加1 . 2wt的vc时,抑晶效果最为明显,晶粒减小至200 - 300nm ,抗弯强度增大到1293mpa 。 |
| 6. | Comparing with the simulated width of the single crystal opal , we find that the artificial opals possess poly - crystallize structure and the average single crystal size is around 103um3 与理论计算的单晶光子晶体的透射谱比较,得出了我们制作的opal的单畴在10 ~ 3 m ~ 3 。 |
| 7. | The results indicate that : ( 1 ) as the drawing ratio increase , the mechanical properties , crystallinity and orientation of uhmwpe fiber all increase greatly , while the average crystal size decreases 结果表明:随拉伸的进行, uhm筋胭e纤维的力学性能、结晶度、取向度均大大提高,而晶粒尺寸逐渐变小。 |
| 8. | Determination of single crystal size in artificial opals by measuring the width of the transmission dip in the f ? direction of face - centered cubic artificial opals with different thicknesses , we determine the size of the single crystal domain in the opal 人工opal光子晶体单畴大小的测定测定了不同厚度的人工opal在? l方向的透射谱,得出opal光子晶体中单畴的尺寸。 |
| 9. | Hi order to obtain good sensitivity , the effects of the sintering conditions on the crystal size and specific surface area of the powders and the sensitivity of the sensors were studied . the proper sintering condition of thick film sensors doped with sn4 + is 450 ' c > 3h . 3 掺杂效应研究方面,在获得了掺锡的? fe _ 2o _ 3气敏元件对co有较好的气敏性能后,对掺锡的? fe _ 2o _ 3基纳米粉体进行了一系列的测试表征。 |
| 10. | Results show that zro2 - ni cermet has clear crystalline interface and uniform distribution . its crystal size is 0 . 3 p m . through analyzing the data of specific heat of zro2 - ni cermet , it reveals that adulterating cobalt can enhance the wetting quality of ni and zro2 用xrd 、 sem研究了zro _ 2 - ni - co金属陶瓷的相结构和形貌,确定了合适的烧结温度,结果表明,材料的晶粒大小和分布十分均匀,晶界清晰,粒度在0 . 3 m左右。 |
