庫侖引力 的英文怎麼說
中文拼音 [kùlúnyǐnlì]
庫侖引力
英文
coulomb attraction-
If the electric charges in the two stars are supposed to be equal, it can be calculated according to the kulun ' s theorem that 19100 nuclear unity masses must have one electron, such that the electromagnetic force produced can provide enough centrifugal force for the rotation
假定兩星所帶的電荷數量相等，根據庫侖定律，我們可以計算出，在兩星中平均每19100個原子單位質量，就必須帶有一個電子電荷，所產生的靜電引力才能夠提供足夠的向心力。When impact applies on a discrete system in which one of constraints is a constant with coulomb friction, the phenomenon of slip - stick at the point can cause the change of friction and the integration for frictional force during infinitesimal impulsive interval becomes impossible according to traditional impulsive dynamics of discrete systems. by introducing a new dimensional time parameter, first - order momentum - impulse differential equations are obtained and the discussion over infinitesimal impulsive interval is transformed into a piece - wise study on the finite region of impulse
在引入新的無量綱的時間參數后，通過建立相應的動量-沖量的一階微分方程，在趨近於零的沖擊區間的討論變為在有限區間中來分段研究含滑動-黏滯的沖擊過程，得到了受到多點打擊的離散系統考慮庫侖摩擦時的動力學的求解方法，即根據沖擊前的初始狀態無需回到繁瑣的微分方程的求解便可以得到沖擊后系統的動力學響應。For the structural engineering, the constitutive relations of concrete members under the strength will be nonlinear or elasticoplasticness, in this paper, ottosen constitutive model is adopted, and mohr - coulomb strength principle is selected as destructive principle, the concrete cantilever beam is analyzed by using nonlinear efgm, the calculation result by nonlinear efgm is compared with the analysis software of adina, the comparing proves that efgm used to dissolve the concrete nonlinear problem is feasible
目前，無網格伽遼金法主要研究都集中在線彈性材料上，在結構工程中，混凝土構件受力后的本構關系為非線性或彈塑性，本文首次在無網格伽遼金法中引入混凝土的ottosen本構模型和莫爾庫侖強度破壞準則，對混凝土懸臂梁等構件進行了非線性無網格分析，並與國際著名結構分析軟體adina的計算結果進行了對比，表明採用無網格伽遼金法解決混凝土非線性問題是可行的。
