In_（0．2）Ga_（0．8）As／GaAs应变多量子阱结构的光调制反射和热调制反射谱的研究

对Ｉｎ（０．２）Ｇａ（０．８）Ａｓ／ＧａＡｓ应变多量子阱在７７Ｋ下的光调制反射谱（ＰＲ）和热调制反射谱（ＴＲ）进行了实验研究．对ＰＲ结果的线形拟合指认了应变多量子阱中子能级的跃迁，并与理论计算结果作了比较．实验对比确认ＰＲ中１１Ｈ、１３Ｈ等跃迁结构为非耦合态、具有电场调制机构的一阶微商性质．而１１Ｌ、３１Ｈ、２２Ｈ等跃迁结构为阶间耦合态，对这些隧穿耦合的低场调制产生三阶微商特性．     

Acute bilateral amaurosis in sphenoid empyema caused by Streptococcus pneumoniae

PATIENT: A 14-year-old boy suffered from an acute bilateral blindness which occurred in 24-h time, accompanied by headache and raised temperature, with inconspicuous optic nerve head and fundus. After diagnosis of empyema with magnet resonance tomography (MRT) the sphenoid sinus was fenestrated and streptococcus pneumoniae isolated. Liquor and serology being inconspicuous, there was no evidence of leucaemic or autoimmune disease, intoxication or intracranial tumor. CLINICAL COURSE: The condition of the patient improved under systemic antibiotic therapy. The bilateral amaurosis remained and opticus atrophy developed. CONCLUSION: A bilateral amaurosis with descending opticus atrophy as a consequence of a sphenoiditis and spreading inflammation to the meninges and the optic nerve in the area of the chiasm is a rare event. The imaging technique of the MRT offers new opportunities for an early and more pointed diagnosis and therapy.

GaP：（N）的背景光谱和发光尖峰

获得高分辨ＧａＰ（Ｎ）光致发光光谱，观察到等电子陷陆束缚激子发光中ＬＯ和ｌｏｃ多声子发射，其强度分布答合泊松分布。将声子伴带区分为直接光跃迁和间接光跃迁，并进行了相应讨论，还观察到局域声子效应－－光谱相似定律和相当显著的背景光谱。     

Neonatal hyperthyroidism caused by TSH receptor antibodies in maternal autoimmune hyperthyroidism

Between July 1993 and December 1994 five term infants of mothers with Graves' disease were hospitalised at the Frühgeburtenstation of the Univ.-Frauenklinik Graz. Four Mothers had elevated TSH-receptor-antibody (TRAb)--levels during pregnancy, one had normalised TRAb-titers. In one case hyperthyroidism was first diagnosed during pregnancy. Three newborns had elevated TRAb-titers; in one of them thyrotoxicosis was diagnosed clinically and biochemically at the second day of life, one newborn had mild hyperthyroidism with tachycardia at the end of the first week of life and one newborn was asymptomatic by immediately initiated therapy. The two other newborns had normal thyroid hormone and antibody levels and no symptoms or signs of hyperthyroidism. The cases are reported and discussed in detail and our overall approach to diagnosis and treatment of neonatal hyperthyroidism in case of maternal Graves' disease will be given.
