雙螺紋螺桿頭部-
In this study, in order to examine the dynamics of tip [ ca2 + ] i together with the dynamics of tip - localized f - actin in vivo, a kind of double labeled material was constructed. the ca2 + and actin microfilaments of arabidopsis pollen tubes were labeled by cameleon and gfp - mtalin respectively
本研究以擬南芥花粉管為材料,通過轉基因技術,將分別標記ca ~ ( 2 + )和微絲的兩種熒光蛋白cameleon與gfp - mtalin在花粉管中同時表達,實現活體花粉管中ca ~ ( 2 + )與微絲的同時標記。 -
The author utilizes double broken line model to show relation between friction and displacement around the pile. the article establishes equation about friction and relative displacement according to elastic or plastic condition that soil around or in the tip of the pile lies in. then we use continuous and border conditions to determine relative displacement
作者用雙折線硬化模型來表示樁側摩阻力與樁土相對位移的關系,並根據樁側土與樁尖土處于不同的彈性和塑性狀態,建立樁身軸向力和樁土相對位移的微分方程,利用連續和邊界條件可解出相對位移,然後再根據相對位移又解出樁軸向力和負摩阻力。
