Theory deduce , experimentation and finite element analysis ( fea for short ) are carried out on b / t ratio of t - section steel 本文從理論分析、試驗研究、有限元計算三方面研究了剖分t型鋼腹板局部屈曲及寬厚比限值。
( 3 ) cu amino acid chelate promoted spleen growth in experiment 21 - 28d , thymus " degeneration were decreased and growth of spleen were promoted by supplemental cu in diet in cu - deficient mice . ( 4 ) cu - met promoted t lymphopoiesis more efficiently , anae + t ratio and t lymphopoiesis were increased by dietary supplemental copper ( 3 )氨基酸螯合銅能夠促進添加銅21天- 28天小鼠的脾臟發育,給缺銅小鼠飼糧添加銅能顯著減緩小鼠胸腺退化和促進脾臟發育。
Theory analysis in this paper pointed out that the flexural - torsional buckling is the usual form of t - section steel . so the slenderness ratio of flexural - torsional buckling should be used when people give out the b / t ratio by the " equal stability " conception . initial stress , defects and tangent modulus are include in the deduce of the paper to get a rational b / t ratio 通過理論分析指出軸心受力剖分t型鋼整體失穩以彎扭屈曲為主,所以在運用“等穩定”方法確定腹板寬厚比限值時應與桿件的扭轉長細比“掛鉤” ,并以此為出發點考慮殘余應力、初始缺陷,應用切線模量推導出了較為合理的腹板寬厚比限值公式。
