The article gave out not only detailed but very real description about growing process of the big size LaAlO3 crystal with Bottom Weighing,CZ method,and also did a reasonable analysis on adverse factors which influence crystal quality.
铝酸镧(LaAlO3)单晶是超导研究领域使用最普遍的单晶体之一,详细介绍了采用下称重,CZ法(Czo-chralski)生长大尺寸(Φ80mm)LaAlO3单晶的工艺条件,并对影响晶体质量的主要因素进行了分析、讨论,给出了解决晶体质量问题的手段和有效途径。
The testing parameters included body composition which was estimated by means of underwater weighting, subcutaneous fatness and its distribution which was measured by means of skinfold thickness, and biochemical variables such as the fasting concentrations of serum leptin, tes.
受试者为36名青春期前活动量较大的7～12岁香港儿童(21男,15女),测试指标包括水下称重所测的身体成分、皮脂厚度、血清瘦素、睾酮和血总胆固醇。
