材料结构差异

但不同发光颜色的电致发光材料结构差异大，利用蓝、黄互补色混合发光器件易发生相分离影响器件稳定性。

However , different colors light-emitting materials is a large difference , and the device prepared by this way is prone to phase separation to affect the device stability .

通过试验观察了Al-TiO2自蔓延高温合成（SHS）和热爆合成Ti-Al2O3金属陶瓷复合材料宏观结构差异，并结合冶金学原理对此作了分析。

The microstructural difference of the Ti-Al_2O_3 cermet prepared by self-propagation high temperature synthesis ( SHS ) and thermal explosion have been examined .

据此，本研究设计制备一种具有双侧疏松或致密程度不同的双层结构材料，以期通过材料的结构差异调整生长因子的释放行为，实现所负载生长因子的时空控制释放。

In this study , in order to realize spatial controlled release of loaded growth factors by adjusting biomaterials structure , a kind of double layered materials was designed and prepared with different density , one dense layer and one loose layer , respectively .
