HDPE/iPP/CB吸波复合材料的导电性能和力学性能研究

利用碳黑（CB）在多相聚合物体系各相中的选择性富集现象，制备出了HDPE／iPP／CB二元聚合物基单层吸波复合材料，使导电相（CB富集相HDPE）为吸波相，有效吸收电磁波能量；非导电相iPP为透波相，作为电磁波进入复合材料的通道．导电性能测试表明，所制备的复合材料中具有明显的渗流现象和二次渗流现象，材料中吸波相和非吸波相并存；力学性能测试表明，适量的CB将增强树脂基体的力学性能，而过量的CB使材料的力学性能下降．分析认为，利用CB在多元聚合物中的选择性富集来制备单层吸波复合材料是一种可行的方法．

Research on the preparation of amorphous diamond nanorod arrays and their excellent field emitting properties

During recent years, with the rapid development of IT and micro-electrics, the ultra- thin, ultra-large display screen with low power consumption, has attracted more and more attention. As the core of devices, cathode materials are made much more demands in the vacuum microelectronic technology. So the materials with low power consumption, outstanding field emission properties and extreme stability are very important. To resolve the problem, many researchers have been making efforts. Diamonds…     

Study on thermal infrared remote sensing of Yarlung Zangbo River and Bangong Co-Nujiang River suture belt in Qinghai-Tibet Plateau

The area change of heat abnormity is not in accordance with conclusions of former thermal infrared remote sensing studies of the Qinghai-Tibet Plateau, which were that the temperature of Yarlung Zangbo River suture belt of the southern Plateau is high and the northern temperature is low. The study result in this paper shows that the highest temperature is found in the Bangong Co-Nujiang River suture belt, the Yarlung Zangbo River suture belt temperature is the second highest, and the northern Tibet temperature is the lowest. The study demonstration area was the suture belt areas of the Yarlung Zangbo River and the Bangong Co-Nujiang River in the Qinghai-Tibet Plateau, where the land temperature of the Qinghai-Tibet Plateau and the bore temperature of field land surface were measured and the emissivity of land surface was calculated. In addition, the authors explore the mechanism of the relationship between thermal infrared remote sensing and constructing thermodynamics and reach four new conclusions about the thermodynamics of the Tibet Plateau.     

Digital Manufacture Techniques for Large Hydro Turbine's Blades

Blades are one of the vital components and most difficulty in manufacturing of large hydro turbines.In order to cost-effectively and productively manufacture these kinds of blades,a series of digital techniques in manufacturing have been devel- oped,which includes digital design of hydro turbine blades based on manufacture' requirements,Computer-aided location and the machined error evaluation by using 3-dimensional digitized measuring,tool path generation strategy to meet requirements of en- hancing machining efficiency and controlling deviation in NC machining,tool path generation and NC machining simulation by es- tablishing a virtual NC machining environment for blades,and reasonable and feasible strategy and the systematic scheme for man- ufacturing of large blades by using 5-axis simultaneous CNC machining.The developed digital manufacture techniques have been successfully applied in manufacturing of both the large Kaplan and Francis hydraulic turbine blades;it shows that higher efficiency and the better surfaces finish accuracy can be achieved.

PMMA／SiO2复合颗粒制备与表征

乳液聚合是对纳米颗粒改性的常用方法。但聚合效果不好且对改善纳米颗粒的分散作用不大。本实验引入硅烷自组装单分子层，采用无皂微乳液聚合法制备PMMA／SiO2复合颗粒。EDS、FTIR、TEM、LSS分析表明．纳米SiO2通过硅烷功能化，可以更有效地与MMA发生化学键合。复合颗粒在水中分散效果明显改善。不规则形状纳米SiO2通过组装而接近球形结构。复合颗粒具有很好的有机相容性和分散稳定性。
