spin density 中文意思是什麼

spin density 解釋
自旋密度
  • spin : vt （spun 〈古語〉 span; spun;spinning）1 紡。2 使（陀螺等）旋轉；使（車輪）打空轉〈在冰上，沙中...
  • density : n. 1. 稠密；濃厚。2. 【物理學】濃度；密度；比重。3. 愚鈍，昏庸。
  1. In consideration of the calculation measures and the purpose of study, we selected the simple molecule model 5 in the above models and studied the relation between magnetism and structure. the molecular antiferromagnetism increases with the increasing of the bridging angle o - c - o ( o ). when 0 > 118. 623 degrees, the molecular antiferromagnetism increases with the decreasing of the spin density on the cu in its triplet state

    考慮到計算量及研究目的，在上面的模型中選取了較簡單的分子模型5 ，來研究其磁構效關系，分子的反鐵磁性隨橋聯角o - c - o夾角的增大而增強，在大於118 . 623度時，分子的反鐵磁性隨三重態銅上自旋密度的減小而增強，但當小於118 . 623度，分子反鐵磁性隨三重態銅上自旋密度的減小反而減小，在文中，我們解釋了這種現象。
  2. Cosmic expansion had diluted the density of the gas to the point where collisions were too infrequent to equalize the spin and kinetic temperatures

    宇宙膨脹至此，已將氣體稀釋到一定的程度，使得原子碰撞不再頻繁地讓自旋與動力溫度相等。
  3. For experimental measurement. the spin density distributions are in detail discussed on the basis of mulliken population analysis, taking into account the coexistence of spin delocalization and spin polarization mechanisms. for

  4. Spin by alkene spunbonded olefin glueing not, with making density polyethylene fibre not high, kinds of use the getting more extensive extremelying, light, but very tough and tensile material

    的紡粘型烯烴spunbonded olefin用高密度聚乙烯纖維製成，是一種用途極為廣泛，重量輕，而卻非常堅韌的材料。
  5. Magnetic properties and spin density maps for rare earth - transition metal complexes : a density functional study

    密度泛函理論方法研究稀土-過渡金屬化合物的磁性和自旋密度圖
  6. But when0 < l 18. 623 degrees, the molecular magnetism decreases with the decreasing of the spin density on cu in its triplet state. in the thesis, we explained this phenomenon. moreover, we also studied the relations between the j and ( e, - e2 ) 2

    另外，我們還揭示了j三重態兩個成單電子所在的分子軌道能量差的平方（ _ 1 - _ 2 ） ~ 2之間的變化關系。
  7. As the representation of the electron spin angular momentum is two - dimensional or three - dimensional, the electron energy is calculated simplier by the theory of density matrix and average value

    當電子在磁場中的自旋角動量的表示為二維和三維時，應用密度矩陣原理求解其能量更為簡便。
  8. Spin by alkene ( spunbonded olefin ) glueing not, with making density polyethylene fibre not high, kinds of use the getting more extensive extremelying, light, but very tough and tensile material

    的紡粘型烯烴（ spunbondedolefin ）用高密度聚乙烯纖維製成，是一種用途極為廣泛，重量輕，而卻非常堅韌的材料。
