| 3. | This nano - crystalline material with " bimodal " structure was viewed as a kind of composite and the idea of nano - / micro - crystalline composite toughening was put forward 用复合材料的观点对具有不同晶粒尺度分布的纳米晶材料进行研究,提出纳米微米晶复合增韧的想法。 |
| 4. | This paper focuses in micro - mechanical investigation on the behavior performance of this nano - crystalline material with " bimodal structure " and main results are as the following : 1 本文对这种具有不同晶粒尺度分布的纳米晶材料进行了理论力学分析,主要工作包括: 1 |
| 5. | Amorphous materials have disordered atomic structure as compared to crystalline materials : that is , they have only short - range order rather than the long - range periodicity of crystals 与晶体材料相比,非结晶体材料使原子结构发生无序变化,即:它们只有晶体的短程序列特征,而没有晶体结构的长期周期性特征。 |
| 6. | Significant increase in hardness and strength has been documented for nano - crystalline materials - most dramatic for nano - structure materials , but ductility is disappointingly low and it is not satisfied in nano - crystalline materials toughening 但目前制备的纳米晶材料,虽然表现出很高的强度,但其塑性很低,韧性性能不理想。 |
| 7. | It has exact processing and heat treatment gate bushing , the part of heat can be delivered to the steel around the gate which make the plastic just enter wouldn ' t be frozen so quickly . it applies to crystalline materials 带精确加工及热处理的一体浇口司,能传递部分热量至浇口区域的金属,使得刚一进入型腔的塑料不至于迅速凝固,适于快速凝结的结晶性塑胶。 |
| 8. | She is currently undertaking research on the synthesis and properties of ldh thin films , spinel ferrite thin films derived from layered double hydroxides , and functional crystalline materials 2003年调入北京化工大学可控化学反应科学与技术基础教育部重点实验室工作,主要研究方向:阴离子层状薄膜和尖晶石铁氧体薄膜材料的制备及性能研究;功能晶体材料制备及性能研究。 |
| 9. | Collection of supramolecules chemistry theory and liquid crystal science results in a novel science field : supramolecules liquid crystals , which is aim to synthesize more and more liquid crystalline material by molecules recognization and self - assembly and acknowledge more about them 这一领域的目标是通过分子识别和自组装,在更广泛的空间去合成新的液晶材料,了解液晶科学领域更多未知的东西。 |
| 10. | Ductility enhancements were achieved in nano - structured metals through the incorporation of a bimodal grain size distribution , with micrometer - sized grains embedded inside a matrix of nano - crystalline grains , and at the same time the strength deceases so little that the nano - crystalline material is toughening well 针对这种情况国外研究人员制备出的一类具有不同晶粒尺度分布的纳米晶材料,在强度降低有限的情况下改善了材料的塑性性能,达到了增韧的目的。 |
