Zr是一种很重要的金属,有很强的吸附能力,但对其表面性能的研究至今还很少报导,可能是不容易得到好的单晶样品和清洁的表面。Moore和Foord等研究过Zr的表面结构和对O2的吸附。以及多晶Zr对气体的吸附。在文[3]报道了Zr的俄歇谱的谱线线

Aim:To study the distribution of anisometropia and anisoa-stigmatismin young Australian children,togetherwith clinical and ocular biometry ***:The Sydney Myopia Study examined 1765 predominantly 6 year old children from 34 randomly selected Sydney schools during ***,cycloplegic autorefraction,and questionnaire data were ***:Spherical equivalent(SE)anisometropia(≥ 1 dioptre)prevalence was 1.6%(95% confidence interval(cI)-1.1% to 2.4%).Aniso-astigmatism(≥ 1D)prevalence was 1.0%(cI:0.6% to 1.6%).Both conditions were significantly more prevalent among moderately hyperopic(SE ≥ 2.0D)thanmildly hyperopic(SE 0.5-1.9D)*** children(SE ≤-0.5D)had higher anisometropia *** condition varied by age,sex,or *** multivariate analyses,anisometropia was significantly associated with amblyopia,odds ratio(OR)29,(cI:8.7 to 99),exotropia(OR 7.7,cI:1.2 to 50),and neonatal intensive care unit(NIcU)admission(OR 3.6,cI:1.1 to 12.6).Aniso-astigmatism was significantly associated with amblyopia(OR 8.2,cI:1.4 to 47),maternal age > 35 years(OR 4.0,cI:1.3 to 11.9),and NIcU admission(OR 4.6,cI:1.2 to 17.2).Anisometropia resulted from relatively large interocular differences in axial length(p chamber depth(p=0.0009).Aniso-astigmatism resulted from differences in corneal astigmatism(p conclusion:In this predominantly 6 year old population,anisometropia and aniso-astigmatism were uncommon,had important birth and biometry associations,and were strongly related to amblyopia and strabismus.

考察了本工作第一部分中所提出的新的电渣过程化学反应及传质横型对SAE1020钢实验室交流电渣重熔的适用性,重熔试验在容量为1t的250kVA电渣炉上进行。锭子名义直径为200mm,相直的电极直径为76mm;所用渣系分别为70wt-％caF2+30wt-％Al2O3（在Ar气氛下）和50wt-％caF2+30wt-％Al2O3+20wt-％caO（在空气中）。重熔过程达稳定状态后分别向渣池分点加入FeO或ca粉,以使体系内产生不连续的氧化-还原反应。用该模型估计锭子和渣的化学成分,结果表明,在试验条件下,该模型与实际重熔过程的观测值非常相符。

端粒是染色体末端的一小段DNA-蛋白质复合体,作用是保持染色体的完整性和控制细胞分裂周期。DNA每次分裂复制会引起端粒缩短,一旦端粒消耗殆尽,细胞将会立即激活凋亡机制,即细胞走向凋亡。端粒长度与老化和多种健康风险密切相关。众所周知,生命早期发育过程中父亲角色的缺失对儿童终身健康存在负面影响,但其生物学效应尚未知。
