t ratio meaning in English

统计系数与标准误差比率

Theory deduce , experimentation and finite element analysis ( fea for short ) are carried out on b / t ratio of t - section steel
本文从理论分析、试验研究、有限元计算三方面研究了剖分t型钢腹板局部屈曲及宽厚比限值。
( 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 )氨基酸螯合铜能够促进添加铜21天- 28天小鼠的脾脏发育，给缺铜小鼠饲粮添加铜能显著减缓小鼠胸腺退化和促进脾脏发育。
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
通过理论分析指出轴心受力剖分t型钢整体失稳以弯扭屈曲为主，所以在运用“等稳定”方法确定腹板宽厚比限值时应与杆件的扭转长细比“挂钩” ，并以此为出发点考虑残余应力、初始缺陷，应用切线模量推导出了较为合理的腹板宽厚比限值公式。
