The latter has only one PL band peaking at about 1.48eV,while the former is a double-band PL spectrum with peaks at both 1.48eV and 1.97eV.The electroluminescenceform the Au／scored Si-rich SiO2 film／p-Si sample is about 6 times in intensity of that of the Au／unscored one.

未刻划样品的PL谱只有一个峰，位于840nm(1.48eV)，而刻划样品的PL谱是双峰结构，峰位分别位于630nm(1.97eV)和840nm.800℃退火的刻划富硅二氧化硅/p-Si样品在背面蒸铝制成欧姆接触和正面蒸上半透明金电极后在正向偏压10V下的电致发光强度约为同样制备的未经刻划样品在同样测试条件下的EL强度的6倍。

Acetabula are outlined, and center of graity is at X. B, Center of graity, X, is anterior to S2 ertebra, although center of graity is not fixed and changes with moement of upper body with respect to pelis.

髋臼已标出，重心位于X点。B：重心X位于S2椎体前方，尽管重心并不固定，可随躯干相对于骨盆的运动发生改变。

At the same time, Beijings political and cultural functions were aggrandized too, and the integration of knowledge and economy made it became a new-economy center.

第四，城市地位、作用变化比较。作为20世纪以来城市发展动力机制与城市功能转变差异的结果，北京、上海城市地位与作用的变化可以被认为是20世纪北京、上海发展异同的最终体现。1 840年以前，北京位于中国封建城市体系的中心，而上海却位于这一体系的边缘，两城市地位的悬殊不可同日而语。
