A rapid and reliable method was developed for analysis of ethephon residues in maize, in combination with the investigation of its dissipation in field condition and stabilities during the sample storage. The residue analytical method in maize plant, maize kernel and soil was developed based on the quantification of ethylene produced from the derivatization of ethephon residue by adding the saturated potassium hydroxide solution to the sample. The determination was carried out by using the head space gas chromatography with flame ionization detector （HS-GC-FID）. The limit of quantification （LOQ） of the method for maize plant was 0.05, 0.02 mg kg-1 for maize kernel and 0.05 mg kg-1 for soil, respectively. The fortified recoveries of the method were from 84.6-102.6%, with relative standard deviations of 7.9-3.8%. Using the methods, the dissipation of ephethon in maize plant or soil was investigated. The half life of ethephon degradation was from 0.6 to 3.3 d for plant and 0.7 to 5.7 d for soil, respectively. The storage stabilities of ethephon residues were determined in fresh and dry kernels with homogenization and without homogenization process. And the result showed that ethephon residues in maize kernels were stable under-18℃ for 6 mon. The results were helpful to monitor the residue dissipation of ethephon in the maize ecosystem for further ecological risk assessment.

诗钟体系庞杂,格目繁多,在长期的播流迁衍过程中又产生诸多变异,因而在格目理论的论述上也就矛盾与错乱之处互见。考察诗钟形成及流变的历史可以发现,与传统律诗、绝句一样,诗钟最初也是五言、六言、七言、骈体并存,之后则经历了从"古格"向"今格"转化的过程。其中,准确把握"笼纱"的实质,合理确立"晦明格"与"咏嵌体"这两种兼类现象在诗钟结构体系中的坐标位置,科学界定"集句"、"白解"等术语的性质范畴,又是理清整个诗钟格目体系及其结构层次的关键。

诗钟以其独特的艺术魅力和大规模的集体创作,在台湾社会历史与文化生活中产生过极其广泛而深刻的影响。特别是日据时期,台湾钟手以诗钟为载体,同声相应,同气相求,广泛开展社际联吟、区域联吟与全岛联吟,从而使台湾诗钟汇聚成声势浩大的诗海钟涛,掀起一股股反抗日本殖民统治、保存和延续中华传统文化的民族文化浪潮。然而,现有台湾文学史特别是台湾现代文学史的写作,大都把诗钟弃置在台湾文学的边缘,有必要加强对它的研究与探讨。

菽庄吟社与上海南社在发展规模、存续时间、创作成就、声势影响等方面均旗鼓相当;然而,由于它们各自形成的社会历史背景不同,人员构成及态度倾向各异,社团宗旨、革命要求、文化取向、诗学传承迥别,加上组织形式、运作机制、经费来源等诸多因素的影响,二者最终呈现出截然不同的发展风貌。从本质上讲,上海南社是清末民初"反清排满"的民族主义革命文学社团,菽庄吟社则是日据台湾时期"抗日复台"的爱国流亡文学社团,分别蕴含特定的社会内涵和独特的历史意义。
