Research of Growth and Scintillation Properties of Ce ∶ Mg ∶ NBW Crystal

Ce∶Mg∶NBW晶体的生长及闪烁性能的研究

The transmission spectra indicate that the NBW crystal has a strong antiradiation damaging feature .

光透射测试结果表明了NBW晶体的抗辐照损伤能力强；

Finally , the high quality NBW crystal of 50 mm in diameter and 35mm in length was generated at first time hi the country .

最终在国内首次长出Φ45mm×35mm大尺寸、高质量的钨酸铋钠晶体；

The manifestation of the deflection of the development quotient of LBW children is obvious , and the detection rate of low weight is statistic difference from NBW .

LBW儿童的生长发育偏离现象明显，低体重的检出率与NBW组相比有统计学差异。

The present development and applied future of Nd : NaBi ( WO4 ) 2 ( for short : Nd : NBW ) crystal is introduced .

研究了Nd：NBW（分子式：Nd：NaBi（WO4）2）以及二元钨酸盐的国内外发展现状和应用前景。

The attack works within a complexity of O ( NbW ) in order to decrypt the message where W is the number of possible words ( typically W = 256 ) .

使用这种方式解密一条信息的复杂度是O（NbW），其中W是可能值的数量（通常W=256）。

Children patients from Children Health Care Out-patient Clinic of Medical School of Qingdao University from June 2002 to March 2004 were in the LBW group . Children in the NBW group were randomly selected from city kindergarten .

出生低体重儿组为2002-06/2004-03青岛大学医学院儿童保健门诊就诊患儿，出生正常体重儿组为随机抽取的市区幼儿园入园儿童。

METHODS : Cognitive development and family environment were examined in 50 LBW children and 50 normal birth weight ( NBW ) children aged 15-30 months with self-made questionnaire of influential factors and Bayley scales of infant development .

方法：采用自制的家庭一般环境问卷、Bayley婴幼儿发育量表对50例出生低体重儿和50例出生正常体重儿15～30个月时的认知发育及其家庭环境进行调查。

The hysteretic behavior , degradations of strength and stiffness , ductility and energy dissipations , the modes of failure of the SPW and SEP connections were compared with those of the NBW connection under different axial compression ratios .

比较了这三种连接节点在不同轴压比下的滞回性能、强度与刚度退化、延性性能、耗能能力以及破坏特征。
