fraction of atoms 中文意思是什麼
fraction of atoms
解釋
原子濃度-
A plasma is a gas in which a significant fraction of the atoms or molecules are ionized.
等離子體是一種其中大部分原子或分子都已電離的氣體。 -
Because of the existence of the holes in the system, the molecular fraction q should considered into the free energies and the gibbs functions. when there are few holes or none existing in the system, i. e., it corresponds to the liquid state or solid state ; when there are lots of holes and a few atoms existing in the system, i. e., it corresponding to the gas state
為了進一步研究固、液、氣三相之間的轉變，我們引入空格點並定義了占據率q ，當空格點幾乎沒有或很少時，即q 1 ，系統對應的是固態或液態；而當空格點很多時，即q 0系統中原子很少，系統對應的則是氣態。 -
A high spin temperature, for example, would indicate that a high fraction of atoms were aligned
例如，高自旋溫度代表較高比例的原子，具有相同方向的自旋排列。 -
In this thesis, a semi - classical model of the force on an atom is used to describe the motion of a two - level atom interacting with a standing wave laser field. the velocity dependent force and momentum diffusion are derived through optical bloch equations by using the matrix form of the continued fraction technique. by investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom
本文利用半經典理論，從二能級原子在激光駐波場中所滿足的運動方程出發，推導出密度矩陣元所滿足的遞推關系，利用矩陣連分數方法求解出密度矩陣元，從而求出依賴于原子運動速度的光壓力與動量擴散系數，通過討論原子在激光場中的動力學行為，為原子在激光場中被囚禁、形成原子列陣以及可控制的量子態，從而為量子信息處理提供理論基礎。
