一种用于宽动态范围上的高精度散射测量的标准方法

The co-effect of transmitted power fluctuation and system nonlinearity produce deviations in scatterometer measurement results . An internal calibration method to deal with this problem is proposed. The method can result in more precise scatterometric measurements in a wide range. The basic principle of the method is combining real-transmitted-power detection with the calibration of system nonlinearity. A practical scheme to implement the method is also presented, which is developed based on a special designed mechanism of a microwave radiometer-scatterometer combined system.

浮士德式求索──《雪国》主题探讨

近年来,对《雪国》主题探讨,可以说＂一千个读者,就有一千部《雪国》＂。可以将其主题归纳为浮士德式求索,主要表现在驹子、岛村和作者川端康成身上。岛村是无目的的求索,最终得到肉体和精神的拯救与净化;驹子虽生活不幸,但依然求索不止;川端康成求索的则是日本的传统美,呈现出＂故乡＂找寻意识,继承和发扬了物哀情调和幽玄理念。     

Phonological Awareness Skills in Young Boys with Duchenne Muscular Dystrophy

Substantial research has detailed the reading deficits experienced by children with Duchenne muscular dystrophy (DMD). Although phonological awareness (PA) is vital in reading development, little is known about PA in the DMD population. This pilot study describes the PA abilities of a group of five young children with DMD, comparing the results with those of a group of children with spinal muscular atrophy and with those of a group of typically developing children. The Preschool and Primary Inventory of Phonological Awareness was used to assess the PA skills of the participants. Results indicated that the children with DMD performed significantly poorer than the typically developing group on tests of Syllable Segmentation, Rhyme Awareness, Alliteration Awareness and Phoneme Isolation and significantly poorer than the spinal muscular atrophy group on Rhyme Awareness. The findings of this pilot study indicate that children with DMD may have an increased risk of having PA difficulties, thus requiring early PA training.
