geometry of numbers
解釋
數的幾何學-
The invent of irrational numbers, calculus, and the found of non - geometry, the prove of fermat theorem. examples like this are uncountable in the history. with the help of it, people will understand better the real process of math creation, which was fixed in our textbook in form of principles, therefore, we can benefit a lot from our ancestors and be very confident of ourselves
無理量的發現、微積分和非歐幾何的創立，乃至費馬大定理的證明， … … ，這樣的例子在數學史上不勝枚舉，它們可以幫助人們了解數學創造的真實過程，而這種過程在通常的教科書中是以定理到定理的形式被包裝起來的。 -
After the evaluation of the three parameters in the proposed creep model, which is based on the large numbers of experimental measurements of concrete creep, the influential regularities of concrete filled steel tube columns under long - term loading are investigated. by dispersing time, the method of tangent modulus is adopted to study the relation of creep strain and load time. in the end, this paper took cft specimens with representative geometry and sectional dimensions as examples and adopted the proposed method as an approach to investigate the influencing regularities of many factors, which include the ratio of long - term load to strength, the slenderness ratio, the eccentricity ratio, and the intensity grade of concrete, on cft structures
在對鋼管混凝土構件長期荷載效應的分析中，本文基於三維粘彈性理論，採用三參數粘彈性模型，提出了核心混凝土徐變的三維有限元分析理論，在總結過去大量關于混凝土徐變試驗實測結果的基礎上擬合了模型中的三個參數，並成功將其應用於鋼管混凝土徐變的三維分析計算中，得到徐變與持荷時間的關系，以典型截面形式的圓鋼管混凝土軸壓、偏壓構件為例，對軸壓比、長細比、含鋼率、偏心率以及核心混凝土等級分別進行了大量的參數分析和實驗對比研究，結果表明二者符合較好。 -
