【摘要】：本文主要對活動星系核（AGN）的吸積盤輻射的研究，在標(biāo)準(zhǔn)吸積盤的基礎(chǔ)上考慮中心黑洞的類型及其旋轉(zhuǎn)和最小穩(wěn)定軌道的變化對吸積盤輻射的影響。利用標(biāo)準(zhǔn)吸積盤、雙溫盤、物質(zhì)流主導(dǎo)和坡印廷流主導(dǎo)的吸積盤模型對3個源進(jìn)行的擬合。 第一章，簡單介紹了活動星系核的基本概念及特征；活動星系核的產(chǎn)能機制和模型；光學(xué)紫外波段的大藍(lán)包及其形成的原因；四種吸積盤各自的優(yōu)點及不足和其相互之間的比較。 第二章，主要介紹了標(biāo)準(zhǔn)吸積盤的輻射模型和黑洞吸積盤最小穩(wěn)定軌道半徑的演化；考慮相對論作用下的吸積盤輻射模型；不同黑洞類型對吸積盤輻射影響的模型；坡印廷流主導(dǎo)和物質(zhì)流主導(dǎo)的吸積盤模型。坡印廷流主導(dǎo)和物質(zhì)流主導(dǎo)的吸積盤的磁場與MHD的張量有關(guān)，所以還對MHD吸積盤進(jìn)行了簡單介紹；以及考慮幾種影響吸積盤輻射的因素，考慮這些參數(shù)變化對吸積盤輻射譜的影響。 第三章，主要是把相關(guān)模型用于擬合幾個源在光學(xué)紫外波段的輻射，，對雙溫盤模型的輻射中做了一小部分的修改，并比較各個模型得到的黑洞質(zhì)量、質(zhì)量吸積率等參數(shù)之間的不同。
[Abstract]:This paper mainly studies the radiation of the accretion disk of the active galactic nuclei (AGN), and on the basis of the standard accretion disk, the influence of the type of the central black hole and the change of the rotation and the minimum stable orbit on the radiation of the accretion disk is considered. The fitting of three sources was carried out using a standard accretion disk, a double-temperature disk, a material flow-leading and a slope-printing-flow-dominated accretion disk model. The first chapter briefly introduces the basic concept and characteristics of the active galactic nuclei, the capacity mechanism and model of the active galactic nuclei, the large blue package of the optical ultraviolet band and the reasons for their formation, the respective advantages and disadvantages of the four kinds of accretion disks and their ratio to each other The second chapter mainly introduces the radiation model of the standard accretion disk and the evolution of the minimum stable orbit radius of the black hole accretion disk, and takes into account the radiation model of the accretion disk under the effect of relativity, and the effect of different black hole types on the radiation of the accretion disk a model of the leading and substance flow dominated by the pottingt flow The disk model is related to the tensor of MHD, which is dominated by the flow-of-slope and substance flow, so the MHD accretion disk is briefly introduced, and several factors which influence the radiation of the accretion disk are considered, and the radiation spectrum of the accretion disk is considered in consideration of the changes of these parameters. In the third chapter, the correlation model is used to fit the radiation of several sources in the optical ultraviolet band, a small part of the radiation of the double-temperature disk model is modified, and the parameters such as the black hole quality and the mass absorption rate of each model are compared.
