从服务业区位功能上,长三角大都市圈城市可以划分为三个等级体系:核心城市——上海;二级城市——南京、苏州、杭州、宁波等;其他三级城市。从资源整合优势看,圈内现代服务业的竞争合作发展应以上海为核心,在上海优先驱动模式下,二级城市与之错位发展,形成水平分工。在该竞争合作发展模式下,通过制定相应战略加速圈内现代服务业的快速发展。

用燃烧法制备了Eu2+,Dy3+共掺杂SrAl2O4长余辉发光材料,研究了不同硼酸掺量对Eu2+,Dy3+共掺杂SrAl2O4长余辉发光材料发光性能的影响。为了分析B2O3在材料制备中的作用,用XRD对所合成材料进行物相分析,用荧光光谱仪记录其发射光谱,并在暗室里拍摄紫外激发下的发光照片。结果表明:硼酸掺量为0.8的样品的发光光谱,其发射峰峰值位于518 nm,是典型的Eu2+的4f5d→4f的特征发射,为一宽谱带发光光谱。硼酸掺量为2的样品的发光光谱,其在518 nm位置的峰十分弱,而在487 nm处同时出现了一个弱峰,整个谱线呈一斜坡状。随着硼酸加入量的不同,Eu2+,Dy3+共掺杂铝酸锶的发光效果、形貌特征均不同。在某一范围内,随着硼酸添加量的增加,合成了发光主晶相,烧结温度有所降低,材料的发光性能和发光亮度均有所提高。

Objective To study the prevalence of different types of neural tube defects （NTDs） in Luliang Prefecture, Shanxi province, where the prevalence of NTDs is unusually high and the correlation between NTDs prevalence and patterns. Methods A surveillance population-based birth defects was performed in Luliang Prefecture, Shanxi province. Results The results of our study showed that the prevalence of NTDs was 2-fold higher in Luliang Prefecture than in other areas of Shanxi province. Unusual patterns of NTDs were found, however, multiple NTDs were relatively common in Luliang Prefecture, accounting for over 13% of all NTDs cases in China. Conclusion The prevalence of NTDs is associated with its patterns.
