In the Chapter 1 of this thesis, we gave brief introduction to the development of X-ray astronomy observations, which is one of the most important and active parts of modern astronomy. Due to the research experiences, we introduced ASCA X-ray satellite and Chandra X-ray Observatory in more details.

X射線天文學(xué)已經(jīng)逐漸成為現(xiàn)代天文學(xué)最為活躍的部分之一，本文首先簡(jiǎn)單介紹了X射線天文觀測(cè)誕生以來(lái)的發(fā)展經(jīng)歷，因研究經(jīng)歷的原因，我們對(duì)ASCA X射線衛(wèi)星及Chandra X射線天文臺(tái)進(jìn)行了較詳細(xì)的介紹。

Methods Firstly, 2-D matrix X with each ECG-cycle as a column vector was constructed. Secondly, the principal components of X based on Karhunen-Loeve Transform were gotten to reconstruct X from the first eigenvector of XXT.

And then, a window-type novel x-ray crystal spectrometer was put forward based on the elliptically curved crystal analyzer. It was coupled to an x-ray CCD camera, and a set of system had been designed and constructed. The spectrograph is useful in the experiments of x-ray diagnostics, for example in x-ray lasers, inertial confinement fusion, laser-matter interaction, and so on.

Paul Erds once posed the following problem about real line R: is it true that, for every infinite set X, there is a closed set E with positive lebesgue measure such that E doesn't contain any subset similar to X (I.e., there is no subset of E, which is a linear homeomorphic image of X). In 1984, K. J. Falconer proved the following: for a decreasing sequence of positive numbers {xn} such that \%lim\%xn=0 and \%lim\%(xn+1)/=1, Erds problem has a partial positive answer.

葉盛 Paul Erds曾提出如下關(guān)于實(shí)直線R的問(wèn)題：是否對(duì)R的每一個(gè)無(wú)限子集X，都存在一個(gè)具有正測(cè)度的閉子集E欧美a免费片，使得E的任何子集都不相似于X(E的任何子集都不與X線性同胚)日韩播放自拍视频下载网站大全免费。1984年，F(xiàn)alconer證明了如下結(jié)論：對(duì)于一個(gè)滿足limxn=0和lim(xn+1)/=1的單調(diào)遞減的正實(shí)數(shù)列{x n}美国一级操逼免费视频，Erds問(wèn)題有一個(gè)部分肯定的解答欧美男女一级性生活视频。

A decrease in Qef value (x = 0 ~ 0.10) with increasing x was dominated by a decrease in the degree of 1:2 order. A increase in relative dielectric constant (x = 0 ~ 0.50) and the positively change of temperature coefficient of resonance frequency (x = 0.10 ~ 0.50) with increasing x were dominated by a decrease in the proportion of [NbO6] octahedra.
