Optical parameters of Er3+ in oxyfluoride glass ceramic.

Er3+在氟氧化物玻璃陶瓷中的光谱性质。

These experimental phenomena could be well explained by the dynamic rate equations of the Er3+-Yb3+ system.It was concluded that the up-conversion properties in the oxyfluoride glass-ceramic were mainly influenced by the strong back transfer process between Yb3+ ions and Er3+ ions.

用Er3+-Yb3+系统的动力学平衡方程解释了这种现象，在氟氧化物玻璃陶瓷中稀土离子的上转换发光主要是受Er3+和Yb3+之间较强的背向能量传输过程影响的。

But the grain growth, grain semiconduction and grain boundary insulation were influenced by many factors, such as the type and contents of dopants, sintering temperature and so on. Therefore, in this thesis the effect of the restore sintering temperature, the oxygenize temperature, the donor and acceptor dopant on the dielectric and varistor properties of devices were studied. With SEM, the microstructure of SrTiO3-based double function ceramic was analyzed.

而晶粒生长、晶粒半导化和晶界绝缘化受到多种因素的影响，诸如杂质的种类和含量、烧成温度等，因此本论文研究了还原烧成温度、中温氧化温度、施主和受主掺杂等对SrTiO_3基陶瓷的压敏和介电性能的影响，并借助于SEM分析对SrTiO_3基双功能陶瓷的微观结构进行了分析。

To raise ozone output of ozonator,it demands that ceramic plate materials for ozonator have good dielectric properties and quite high thermal conductivity.

为了提高臭氧发生器的臭氧产量，要求臭氧发生器用的陶瓷基板材料具有较高的介电性能和热导率。

Haversion system was clearly observed and matured bone tissues filled the ceramic pores and interconnected with each other. All the result suggested that, taking advantage of"living organic culturing medium"in vivo, culturing composite that consisted of autogenous periostea and biomaterials should be an effective approach to obtain satisfactory bioactive bone substitutes which have the potential to repair load-bearing bone defects clinically.

上述研究表明，1、双相多孔TCP/HA陶瓷是一种优良的骨组织工程支架材料，进一步优化其骨诱导作用后，有可能直接用于再生和重建负重骨干的缺损；2、在目前情况下，以双相多孔TCP/HA陶瓷为支架，通过体内非骨位置培养骨组织细胞形成活体骨修复器件，有可能用于负重骨干缺损的再生和重建。
