俘獲分佈
英文
capture distribution-
Finally we focus our attention on studying the emission spectrum of two atoms driven by a single - mode field in an ideal cavity. we showed that the atomic emission spectrum is insensitive to the phase of field for the two atoms initially in the coherent superposition state tf / = v2 / 2 ( j +, - ) h ? + } ), when the two atoms is initially prepared in ( fs * } = cos ( 0 / 2 ] +, + ) + sm ( 0 / 2 ) ei ' p -, - ), the atomic emission spectrum is associated with not only the field photon - number distribution and the atomic populations, but also the phases of the field and the atomic dipole
接著考察了好腔中由單模量子場驅動的雙原子發射譜，結果表明初態為的雙原子發射譜與驅動場的相位無關；而初態為的雙原子發射譜不僅與光場的光子數分佈以及原子的布居數有關，而且依賴于光場的相位以及原子偶極矩的相位，並且在適當的條件下，壓縮真空場可將雙原子俘獲在相干疊加態。The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies. furthermore, it can put more accurate constraints on the chemical evolution of neutron - capture elements. the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
貧金屬星的中子俘獲元素豐度分佈能提供星系形成后各個階段核合成的較為直接和詳細的信息，並為星系化學演化的研究提供更為準確的約束，這一問題的解決將對核天體物理及星系化學演化的一系列問題的解決產生重要影響。The experimental results show that the surface charging is related with the pre - flashover events, the pre - flashover events can bring the change of surface charge distribution. these may be attributed to the micro - discharge caused by the traps in insulator. the charge carriers can be captured by traps, a space electric field will be set up by the trap centers, and the combined electric field may exceed the breakdown electric field of local area, then the micro - discharge will be initiated
分析表明，反向預閃絡現象與材料的陷阱分佈有關，試樣中電極附近的陷阱中心俘獲載流子后所形成的空間電場的作用是產生這一現象的原因；預閃絡現象和表面帶電現象都是由於絕緣子表面陷阱中心俘獲載流子形成空間電場造成局部場強過強引發的局部放電形成的。In pulsed field magnetization condition, we find some new phenomena characteristic, that is, the trapped fluxes of ybco bulk increase with increasing intensity of applied field up to about 1. 9t, but decease beyond this value and the scanning distribution map of the trapped fluxes on the surface of the superconductor is not slick, which is different with the superconductors magnetized in constant magnetic field and the normal permanent magnets
超導體在脈沖場下具有特殊的勵磁特性，當脈沖場在1 . 9t左右時，由於在脈沖場下超導體內的磁通線運動受到較大的粘滯力作用，超導體表面中心的俘獲場分佈掃描圖將出現一些凹陷區域，這是跟超導體在恆定場下的勵磁和一般永磁體所不同的。Sixteen sup - processed from 110k to 300k were found. the range of trap energy is from 0. 19ev to 0. 34ev. the maximum of the initial density distribution of the carrier in the traps locates 0. 23ev, and the curve deviated from guass type
本文採用一種tl曲線的自動分解技術，對硅橡膠輻照老化tl曲線進行了自動分峰，結果發現在110k ~ 300k的溫度范圍內有16個子過程，其陷阱活化能變化范圍為0 . 19 ~ 0 . 34ev ，被陷阱俘獲載流子初始濃度的分佈在0 . 23ev處具有極大值，且呈偏離高斯型的分佈。The expressions of average value and variance of the phase difference and sum components are presented. we verified that under an appropriate condition the interference between the different transition processes makes counter balance, which induces the atom - field coupling system to be decoupled. the atomic population coherent trapping will take place
模的相位保持隨機分佈，給出了光場兩個模相位差以及相位和的平均值與方差表達式，揭示了在適當的條件下，由於不同躍遷通道間的量于干涉效應，光場與原子退耦合，系統呈現原子布居數的相干俘獲現象。分享友人
