《豳风·九罭》:不想让你走

当代学生 2024年第12期 28-29页

作者：兰保民.tp(图) 上海市教师教育学院不详

九之鱼,鳟鲂。我之子,衮衣绣裳。鸿飞遵诸,公归无所,于女信处。鸿飞遵陆,公归不复,于女信宿。是以有衮衣兮,无以我公归兮,无使我心悲兮!《豳风·九罭》是一首表达挽留之情的诗。正是从这首诗中我才真正体会到,所谓“挽留”,根本就不是... 详细信息

九之鱼,鳟鲂。我之子,衮衣绣裳。鸿飞遵诸,公归无所,于女信处。鸿飞遵陆,公归不复,于女信宿。是以有衮衣兮,无以我公归兮,无使我心悲兮!《豳风·九罭》是一首表达挽留之情的诗。正是从这首诗中我才真正体会到,所谓“挽留”,根本就不是委婉地劝留;它表达的是在对方就要离开的时候,紧紧地攀住他的手,频频地拉着他的衣袖,言辞、动作和眉眼表情之间,所表达的无非就是一个意思:“我真的不想让你走。”

蝎子虽毒作用大

当代学生 2024年第14期 94-95页

作者：卜云高艳.tp(图) 上海自然博物馆不详

一提起蝎子,总会让人联想到疼痛或者中毒,它尾巴上的毒刺让人望而生畏、敬而远之。在我国传统文化中,蝎子也被列为“五毒”之一,且位居五毒之首。在动物分类上,蝎子是节肢动物门、螯肢亚门、蛛形纲、蝎目动物的统称。它们全身披着厚厚... 详细信息

一提起蝎子,总会让人联想到疼痛或者中毒,它尾巴上的毒刺让人望而生畏、敬而远之。在我国传统文化中,蝎子也被列为“五毒”之一,且位居五毒之首。在动物分类上,蝎子是节肢动物门、螯肢亚门、蛛形纲、蝎目动物的统称。它们全身披着厚厚的外骨骼,像一名穿着铠甲的战士。身体最前端的触肢像一对左右开弓的大钳子,那是它们用来捕猎的武器,另外还装备了四对用来快速行走的步足。

Earthquake Engineering and Engineering Vibration 2017年第1期16卷 181-198页

The seismic performance of bridges depends on the ductile behavior of its column, as the deck and other substructural components except pile foundations are normally designed to be elastic to facilitate bridge retrofitting. Codes such as AASHTO, Caltrans, IRC： 112 etc. give guidelines for the seismic performance enhancement of columns through ductile detailing. In the present study, a methodology for the seismic performance enhancement of bridges is discussed by using a ＂Parameter-Based Influence Factor＂（PIF） developed from factorial analysis. The parameters considered in the factorial analysis are： percentage of longitudinal reinforcement （Pt）, compressive strength of concrete （f＇c）, yield strength of steel （fy）, spacing of lateral ties （5） and column height （/4）. The influence of each parameter and their combination on the limit states considered is estimated. Pushover analysis is used to evaluate the capacity of columns, considering shear failure criteria. A total of 243 （35 combinations） analysis results are compiled to develop ＇PIF＇ used in the performance enhancement process. The study also encompasses other sub-objectives such as evaluating the discrepancies in using the Importance Factor （/） in designing bridges of varied functional importance; and estimating the aspect ratio and slenderness ratio values of bridge columns for its initial sizing.
