"A而B之":一种灵活实用的语言结构     

项菊 《黄冈师范学院学报》2001,21(4):56-58

“A而B之”是现代汉语中的一种框架式结构，在句中可作谓语，定语，状语等，还可构成独立语或小句。“而”、“之”的法不同，反映出“A而B之”的语义关系复杂多样。“A而B之”表达独特，用法灵活，语用价值颇大，是现代汉语中一种颇为实用的语言结构形式。  相似文献

Corner strength enhancement of high strength cold-formed steel at normal room and elevated temperatures     

Ju Chen  Wei-liang Jin 《浙江大学学报(A卷英文版)》2008,9(9):1251-1257

In this study, the suitability of current design methods for the 0.2% proof yield strength of the comer regions for high strength cold-formed steel at normal room temperature was investigated. The current standard predictions are generally accurate for outer comer specimen but conservative for inner comer specimen. Based on the experimental results, an analytical model to predict the comer strength of high strength cold-formed steel at normal room temperature was also proposed. The comparison indicated that the proposed model predicted well the comer strength of high strength cold-formed steel not only at normal room temperature but also at elevated temperatures. It is shown that the predictions obtained from the proposed model agree well with the test results. Generally the comer strength enhancement of high strength cold-formed steel decreases when the temperature increases.  相似文献   

Behaviour of cold-formed stainless steel beams at elevated temperatures     

Ju Chen  Wei-liang Jin 《浙江大学学报(A卷英文版)》2008,9(11):1507-1513

A study of the behaviour of constructional cold-formed stainless steel beams at elevated temperatures was conducted in this paper. An accurate finite element model （FEM） for stainless steel beams was developed using the finite element program ABAQUS. Stainless steel beams having different cross-sections were simulated in this study. The nonlinear FEM was verified against the experimental results. Generally, the developed FEM could accurately simulate the stainless steel beams. Based on the high temperature stainless steel material test results, a parametric study was carried out on stainless steel beams at elevated temperatures using the verified FEM. Both high strength stainless steel EN 1.4462 and normal strength stainless steel EN 1.4301 were considered. A total of 42 stainless steel beams were simulated in the parametric study. The effect of temperatures on the behaviour of stainless steel beams was investigated. In addition, a limiting temperature for stainless steel beams was also proposed.  相似文献
