Afterl95os, due to the development of quantum electronics, a new embranchment appeared, which is laser physics, it ? also called the physics of quantum transitions because of the emanation of electronic technology. the symbol of laser physics is the noble physics prize in 1964. the naissance of laser physics is the landmark in the cognition of naturalness
20世紀中葉以後由於量子電子學的發展而出現了一個新的分支，以研究激光物理機制，探索新型激光器，已形成了專門的學科，即激光物理，或因激光發源於電子技術而稱為量子躍遷物理學，它是以1964年的諾貝爾物理學獎為標志的。The study indicate that sral2o4 : tb3 + phosphor can be composed from 1250c to 1550c, the phosphor ' s luminance reduce and the afterglow time shorten along with the compounding temperature ; the better luminance and afterglow with the better crystalloid degree ; the luminescence of tb3 + ion in the sral2o4 is coming from the transition of 5d4 - 7fj ( j = 6, 5, . . . 0 ) ; the afterglow is because of the electron that seized in the trap released which integrate with the luminescence center
合成發光體亮度隨合成溫度的降低而逐漸降低，余輝時間逐漸縮短；當合成物具有較好的結晶度時，合成的發光粉不僅發光亮度高而且余輝時間長； tb ~ （ 3 + ）離子在sral _ 2o _ 4基質晶格中的發光主要來自於~ 5d _ 4 ~ 7f _ j （ j = 6 ， 5 ， … … 0 ）的躍遷；其餘輝是因為不斷有被陷阱所俘獲的電子釋放出來與發光中心復合。Dependence of form factors of 0 transition to the finiteness of the resonance widths
0躍遷的形狀因子對共振態譜有限寬度的依賴性Simple organic molecules tend to be colorless with electronic transitions in the uv, whereas visible absorption, or color is usually associated with electronic in extended and conjugated structures. color is influenced considerably by the extent of conjugation, as well as by the molecular environment imparted by substituents. the reports on organic hydrate thermochronlic material are relatively fewer
本文利用液相和室溫/低熱固相反應合成出變色溫度較高的具有良好熱色性的雙席夫堿及其配合物；過渡金屬離子具有d軌道，其配合物容易引起d - d躍遷或荷移躍遷，因而它們具有豐富的顏色。There are distinct changes about shifts or intensity in bulk plasmon, surface plasmon, and interband electron transitions losses as a result of oxidation of specimens, and adsorption and oxidation processes can be studied through these changes. at room temperature, the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen, and the resultant oxide in each case was near - stoichiometric uo2. due to formation of niobium oxide in uranium - niobium alloys, the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented, and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究結果表明：清潔表面鈮和鈾的體等離子體振蕩所造成的電子能量損失的實驗值與理論計算值較為符合；隨著氧化程度的加劇，表面等離子體（ sp ） 、體等離子體（ bp ）以及價帶電子躍遷所造成電子能量損失的譜峰發生了明顯的連續偏移或強度的變化，這些變化可以用來分析鈾及鈾鈮合金的初始氧化過程；室溫下，鈾及鈾鈮合金很容易與氧作用，最終結果，鈾僅氧化為二氧化鈾，另外，在鈾鈮合金氧化過程中，因為有鈮的氧化物存在，不利於氧和鈾在界面擴散，增強了鈾鈮合金抗氧化性能； eels能獲得樣品表面的信息比aes更為表面，更為靈敏，但由於eels的譜線過于集中，主要在幾十ev以內，也有不容易區別和解譜的不足。There is an obviously increase on the resistivity of the composite sample doped with the increasing of the ( ni, zn ) fe2o4 content, which can be due to the following two reasons : ( 1 ) the grain size of ferrite is much larger than one of lao. ? sro smnos
2隨著鐵氧體材料（ ni ， zn ） fe _ 2o _ 4含量的增加，復合體系的電阻率迅速增大。分析其原因，這一方面可歸結為，大量異質界面的增加使得電子通過隧穿機制在界面之間的躍遷就變得更為困難，從而導致了體系電阻的增大。The method plays an important role in distinguishing and studying the complicated and confused spectral characteristics and mechanisms of the rare earth. ( 2 ) it is found and explained that due to the boltzmann distribution law at room temperature, the positions of the fine peaks of the photoluminescence band stemming from the transitions between an excited state and the ground state of a re3 +, match these of the absorption bands from the transitions between the ground state and the excited state. the stark split energy levels of the ground state 4i15 / 2 and two excited states 2s3 / 2 and 4f9 / 2 of the er3 + in er203 have been determined
薛理輝武漢理工大學博士學位論文摘要（ 2 ）發現在常溫下，由於boltzm ~分佈律的作用，在re3 +的基態電子態和激發態間躍遷所產生的發光譜帶和吸收譜帶中的精細譜峰的位置一一相同，解釋了產生這種關系的原因，並弄清了er203中er3 +的基態電子態4lts . 12和激發態電子態2凡/ 2 、 4凡/ 2的stark能級分裂情況，確定了常溫下erzo3中er3 +的4了15 / 2一2凡/ 2和『 i ， 5 / 2一『凡/ 2精細能級間的躍遷形式。The calculation of b transitions form factor
躍遷形狀因子的計算For the transition induced by the asymmetric perturbations is double - direction, the particle number in the core state is always less half of the total particle number. so, from the point of view of average over time, it is a coexisting state of rotating and without rotating that is formed. this state which is in the josephson tunneling regime of the macroscopic quantum tunneling is a quantum self - trapping state
由於不對稱的微擾引起的躍遷是雙向的，使得核心態上的粒子數總是少於總粒子數的一半，因此從時間平均的角度看，形成的是旋轉的和不旋轉的態共存的狀態，而且處于宏觀量子隧穿的約瑟夫森隧穿區域中，是量子自束縛狀態。In contrast with them, those below the above - cited eigenvalue, i. e., 5, 16 and 25, which have relatively narrow flounce range and low sensitivity, are called " inert eigenvalues ". 4
