  1. Astronomers have also detected older and smaller m stars, previously thought to be quite dim, that actually outshine the sun in their x-ray emission.

    天文學家還探測到有一些較老較小的M型星，它們發射的X射線實際上比太陽更加光輝燦爛，而先前人們卻認為它們是十分幽暗的。
  2. It is found that the fwm field can cause the asymmetry of electromagnetically induce transparency profile. in addition, the effect of different propagating orientations of probe field on the electromagnetically induced transparency is also discussed. in the molecular multi - level system with the perturbed superposition levels, we discuss the electromagnetically induced transparency, spontaneous emission enhancement, double dark resonance and double electromagnetically induced transparency by using the density matrix equation under weisskopf - winger approximation and dressed - state density matrix equation

    針對實際的實驗條件，考慮了一種影響量子干涉的新的因素-四波混頻場，研究了四波混頻場對雙光子探測的-型能級體系的eit的影響，發現四波混頻場能夠導致雙光子探測的eit線型的不對稱，在此基礎上，討論了不同探測場的傳播方式對eit的影響，針對分子中實際存在的包含有微擾能級的不同多能級系統，我們分別採用綴飾態繪景下的密度矩陣方程和weisskopf - wigner近似下的密度矩陣方程詳細地討論了電磁感應透明、自發輻射的干涉相消和相長、雙暗態共振和雙電磁感應透明現象。
  3. After measuring dark current, photocurrent and response to x pulse of gaas detector before and after 1. 7 mev electronic radiation, the response tune, fall time of trailing edge, full width of half maximum ( fwhm ), sensitivity, carrier life, mobility are researched and contrasted. the result shows that the response speed of detector, time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation. though sensitivity of the detector reduces, its measuring range can be widened

    為了使探測器的性能得到進一步的提高，我們對其進行了電子輻照改性，並測量了本徵砷化鎵探測器和經過1 . 7mev電子輻照的探測器的暗電流、光電流及對x射線的脈沖響應，並對其響應時間，后沿下降時間，半高寬（ fwhm ） ，載流子壽命，靈敏度進行對比，研究，結果顯示經電子輻照后的探測器的性能得到了改善，使響應速度，分辯率進一步提高，並消除了探測器輸出信號后沿的非線性，雖靈敏度有所降低，反而使其測量范圍得以拓寬。
  4. That ’ s why the quality of the photodetector can ’ t be insured. according to the existing theory, the dark i - v characteristics and the i - v characteristics under illumination are simulated using matlab software and medici simulator

    在現有理論基礎上，利用matlab和medici軟體，對gan基msm紫外探測器進行了模擬，獲得了該器件的暗電流與穩態光照下電流的i - v關系曲線。
