Effective attenuation coefficients and diffuse reflectance spectra of acupuncture point and non-acupuncture point were measured in vivo before and after the brachial artery was constricted with a *** results showed that the effective attenuation coefficient of acupuncture point was smaller than that of non-acupuncture point. When the brachial artery was constricted, the effective attenuation coefficients of acupuncture point and non-acupuncture point ***, the increasing amplitude of effective attenuation coefficient of acupuncture point was smaller than that of the non-acupuncture point. Diffuse reflectance of acupuncture point was lower than that of non-acupuncture point within the wavelength range of 470 to 600 nm. Both the diffuse reflectance of acupuncture point and nonacupuncture point decreased after the brachial artery was constricted. These experimental results indicated that the optical characteristics of acupuncture point tissues were correlated with the physiologic changes. Therefore, these optical characteristics of acupuncture points would be helpful to study the mechanism of acupuncture meridian.

德国诗人斯特凡·格奥尔格在一战前夕出版的诗集《联盟之星》中提出“神圣的战争”,一直被人误解为支持威廉二世发动战争的宣言。本文解读《联盟之星》里的两首诗以及格奥尔格在1917年创作的长诗《战争》,分析格奥尔格的“神圣的战争”的含义,认为他同时还预言了另一种神圣的拯救之战,即他和弟子们用诗歌创造新生活,这两种战争合在一起构成了格奥尔格的神圣战争观。格奥尔格的神圣战争观具有一种乌托邦性。

斯特凡·格奥尔格是19世纪末20世纪初德国著名诗人。1892年,他在巴黎出版了诗集《阿尔嘎巴》,其中最著名的一首诗《我的花园不需要空气不需要热》,被德国学者称为其"唯美主义的纲领诗"。本文把这首诗与法国唯美主义文学经典文本进行比较,并结合唯美主义的核心理念"为艺术而艺术"在19世纪欧洲的演变以及康德、席勒的审美理论,对这首诗进行文本细读。本文认为,格奥尔格作为一个德国现代诗人,他在吸收法国唯美主义艺术的同时,又返回到了康德与席勒的美学传统,以自己独特的艺术实践,宣告了唯美主义思潮这一"世界性因素"从英国、法国传到德国诗坛以后发生的美学的变化与突破。
