gaussian law 中文意思是什麼
gaussian law
解釋
高斯定律-
Given the initial conditions including ( 1 ) number density distribution in space which has the similar form to the present day ones, ( 2 ) both the power law and gaussian mass functions for clusters, and ( 3 ) two different velocity distributions which one has a constant dispersion and the other is described by the eddington formula, the dynamical evolution of globular clusters in our milky way galaxy is investigated in detail by means of monte carlo simulations
本文採用與觀測結果具有相同形式的球狀星團空間密度分佈函數，在給定兩種球狀星團系統的初始質量譜（冪律的和對數高斯的）和兩種球狀星團系統的初始速度分佈函數（愛丁頓速度分佈函數和常數的速度彌散度）條件下，我們採用montecarlo的方法對球狀星團系統的動力學演化進行討論。 -
Comparing with the current observations, which include the number density distribution in space, mass function, etc., the so - called standard modes for both the power law and gaussian cluster initial mass functions are selected among many runs of simulations. the deviation from the standard modes, which is resulted from the change of the parameter for the initial conditions, is discussed in detail. the discussion of the model parameters is also presented although they are adopted as the typical values based on previous work
對應一定的初始分佈我們發現無論是冪律的還是對數高斯的球狀星團初始質量譜經過長時間的動力學演化都會得到和現在銀河系觀測到的球狀星團系統相符的對數高斯的質量分佈；動力學演化會明顯地改變球狀星團系統的空間密度分佈，靠近銀心區域的球狀星團瓦解得更多；經過動力學演化后的球狀星團速度分佈函數在靠近銀心的區域明顯得不同於初始分佈，初始擁有較大軌道偏心率的球狀星團更容易瓦解。 -
In addition, the influence mechanism of noise on the enhancement ratio is discussed. from the simulation examples, we find the law that random gaussian white noise influencing synthesized images
另外還分析了噪聲對解析度提高倍數的影響，通過模擬實驗，找到了合成圖像受隨機高斯白噪聲影響的規律。 -
Starting from the propagation law of partially coherent light and using a typical partially coherent light, i. e., gaussian schell - model ( gsm ) beam describing the multimode laser in practice, i present in this dissertation the research results on vectorial partially coherent light, spectral changes of partially coherent light passing through optical element, spectral switch of partially coherent light diffracted by an aperture, and the spectral anomaly of diffracted fully spatially coherent light by an aperture
本文從部分相干光的傳輸理論出發，以模擬實際多模激光的一類典型部分相干光? ?高斯-謝爾模型（ gsm ）光束為主要研究對象，對矢量部分相干光、部分相干光通過光學元件的光譜變化、被光闌衍射的部分空間相干光的光譜開關和被光闌衍射的完全空間相干光的光譜異常等現象進行了深入研究。
