作者 汤炳书 《量子光学学报》 CSCD 2001年第3期108-112,共5页
应用on -shell方法研究弱无序情况下的二维光子晶体 ,无序的引入使得原来不透电磁波的禁带中 ,出现了共振模 ,即某一波长的电磁波可以透过 ,计算结果表明共振模的出现位置 ,条数多少及透过率随着无序程度的不同而变化。

光通过弱无序散射介质时可产生分支流现象。针对激光在肥皂液薄膜中的传播,本文利用分步傅里叶变换方法数值求解等效薛定谔方程,探究了光波长、肥皂液浓度、肥皂膜厚度等因素对光分支现象的影响。理论分析及数值计算显示,有效势场变化... 光通过弱无序散射介质时可产生分支流现象。针对激光在肥皂液薄膜中的传播,本文利用分步傅里叶变换方法数值求解等效薛定谔方程,探究了光波长、肥皂液浓度、肥皂膜厚度等因素对光分支现象的影响。理论分析及数值计算显示,有效势场变化幅度越大、关联长度越小,分支现象越明显;相应地,激光波长越小、肥皂液浓度越高、肥皂膜厚度变化幅度越大、厚度变化关联长度越小,则分支现象越明显。在此基础上,我们通过实验验证了多种参数对光的分支现象的影响,得到了与理论分析及数值计算相一致的结果。本研究理论与实验相辅相成,有助于学生理解光分支现象的产生机制,可作为创新性或居家物理实验教学参考。 展开更多

OBJECTIVE: To investigate the effectiveness of acupuncture in the treatment of chronic schizophrenia and co-morbid sleep disorders.METHODS: A 42-year-old German male outpatient,suffering from long-term schizophrenia and sleep disorders, entered the study. Acupuncture was used as a non-pharmacological intervention. In addition to his ongoing Western Medicine(pharmacological) treatment, the patient received 12 weekly(non-standardized) acupuncture treatments in the clinic. The Traditional Chinese Medicine(TCM) diagnosis, the psychological assessment and the actiwatch data were compared before and after the acupuncture treatment.RESULTS: The TCM diagnosis revealed a Liver Fire pattern before the acupuncture treatment, which was still present, although to a lesser degree, after the treatment. The psychological assessment revealed no change in the positive symptoms, but a small decrease in the negative symptoms and the general psychopathology of the patient. This was further illustrated by the small decrease in the number of depressive symptoms. The subjective sleep disorders improved markedly after acupuncture treatment, but the daytime sleepiness did not. The actiwatch results showed that after acupuncture treatment, the patient was moving less during sleep, but no significant results were found for the other sleep parameters.CONCLUSION: Acupuncture was found to be an effective non-pharmacological add-on method for treating subjective sleep disorders, and, to a lesser degree, objective sleep disorders and the negative symptoms of chronic schizophrenia. Future larger clinical trials with follow-up measurements are needed in order to replicate the present preliminary beneficial acupuncture findings and in order to determine whether the observed effects can be sustained. 展开更多
