  1. By using the multi - configuration dirac - fock ( mcdf ) method, the effects of relaxation and correlation on the transition energies and probabilities of electric - dipole allowed ( el ) resonance and intercombination transitions for 2p53s3 - 2p6 in neutral neon have been systematically studied firstly. and the results of the transition energies and probabilities ( lifetimes ) in length and velocity gauge have been presented. during the calculation, in order to consider the rearrangement effects of the bound - state density and some important correlations, the asfs of transition initial - and final - states were divided according to their angular - momentum and parity and calculated, and different number of csfs were included in the expansion of asfs

    本文利用多組態dirac - fork （ mcdf ）理論方法，通過對輻射躍遷初、末態電子波函數的獨立計算以及在原子態波函數的展開中考慮不同數量的組態波函數，系統地研究了弛豫和相關效應對中性ne原子2p ~ 53s ~ （ 1 . 3 ） p _ 1 ~ o - 2p ~ 6 ~ 1s _ 0電偶極共振和復合躍遷的能量以及躍遷幾率的影響，給出了長度和速度兩種不同規范下激發態的能量和輻射壽命；以中性ne原子的研究為基礎，進一步研究了類ne等電子系列離子（ z = 11 - 18 ）較低的激發組態2p ~ 53s和基組態2p ~ 6的能級結構以及各能級間的輻射躍遷特性。
  2. The president not only put him in charge of the transition but allowed him to install allies atop both the treasury and defense departments and place former aides at choke points throughout the government

  3. The general measures carried out by african countries are as follows : reduced administrative rationing of foreign exchange, eliminated many non - tariff barrier, allowed the private sector to compete with parastatals freely, adopted price formulas with a clear link to world pricing, devalued the real exchange rate, reduced the taxation of african fanners, relaxed labor control et al. the implementation of these measures and the transition of economic policy led to the positive effects, got the price - market signals right and promoted the allocation of economic resources

    雖然政策調整過程中有一些新問題出現，但從總體上講，以市場為導向的經濟政策在一定程度上消除了經濟發展過程中存在的障礙，促進了生產要素按照市場原則進行最優的配置，有利於市場體系的建立、健全，並逐步強化了市場競爭機制，促進了資源的有效配置和經濟的發展。
  4. We consider two situations : ( i ) the light is polarized along the z - direction, in which case the first allowed dipole transition is to the first subband ( nx - 1, ny = 1 ) ; ( ii ) the light is polarized along the x - direction ( paralleled to the transverse cross - section of the wire ). the first allowed dipole transition is to the second subband nx = 2 relative to the x - direction and to the first subband nr = 1 relative to the y - direction of the wire
