orbit n. 1.【天文學(xué)】軌道;【解剖學(xué)】眼窩,眶;(鳥或昆蟲的)復(fù)眼緣的頰部。 2.(人生的)旅程,生活過程;勢力范圍。 vt. 使(人造衛(wèi)星、宇宙飛船等)進(jìn)入太空軌道運(yùn)行;環(huán)繞(天體等)作軌道運(yùn)行。 vi. 環(huán)行;(人造裝置等)沿軌道運(yùn)行,達(dá)到軌道飛行所需的速度。 n. -er (繞)軌道飛行器。
10 picometers : in this miniature world we could observe the electrons orbiting the atoms 10皮米:在這個微小的空間中,我們可以觀察電子環(huán)繞原子旋轉(zhuǎn)。
In summary , the up and down quarks make up all the nuclei and electrons orbiting around nuclei form atoms 總括來說,上夸克和下夸克組成原子核,而電子則圍繞原子核而形成原子。
Adjacent elements in a row differ from one another by a proton in the nucleus and an electron orbiting that nucleus 每一行中比鄰的兩個元素的區(qū)別是原子核中的質(zhì)子和圍繞它的旋轉(zhuǎn)的電子的不同。
( 4 ) the mn electron orbits of stoichiometric limn2o4 became degenerated and the electrons settled in disordered states at 320k ~ 280k and therefore the resistance of the material increased slowly with the temperature decrease ( 4 )化學(xué)量的limn _ 2o _ 4材料,在320k 280k的范圍內(nèi)mn原子軌道電子態(tài)簡并,電子處于無序狀態(tài),材料的電阻隨溫度的降低,緩慢增加。
Abstract : the magnetic moment of a hydrogen atom is calculated by using the solution of the relativistic wave equations . it is shown that the so called total magnetic moment are produced from the electron orbit motion . these results show that the total angular momentum j is actually the relativistic orbital angular momentum 文摘:利用氫原子的相對論性波動方程解計算了氫原子的磁矩.結(jié)果表明,現(xiàn)行量子理論中所謂的總磁矩實際上都是由電子的軌道運(yùn)動產(chǎn)生的,由此提出了所謂的總角動量實際上是相對論性軌道角動量的看法
In 1909 , ernest rutherford showed that atoms were mostly empty space , revising the model of an atom to a tight positive nucleus containing the protons and neutrons with electrons around it ; by 1913 , danish physicist neils bohr envisioned a planetary arrangement in which the electrons orbited the nucleus at different energy levels 在1909年,歐內(nèi)斯特?盧瑟福展示原子大部分是真空區(qū),修正的原子模型就是緊密的陽性核包含質(zhì)子和中子,電子圍繞中子旋轉(zhuǎn);到1913年,丹麥物理學(xué)家尼爾?波爾想象了一個電子以不同能量水平面圍繞原子核旋轉(zhuǎn)的行星排列。
