To assess the importance of quasar outflow we have performed a series of studies on broad absorption line quasars, and have obtained the following results.

为了确定外流的重要性，中国科学技术大学天体物理中心开展了宽吸收线类星体的一系列研究，取得了一些进展：(1)宽吸收线区的紫外吸收物质的柱密度比原来预计高出2个量级，低电离吸收线形成于饱和的高电离吸收线区；(2)射电宁静的宽吸收类星体吸收物质主要在赤道面，并且不同的源吸收物质分布情况很不相同，而在射电强的类星体中，赤道和极向外流都是可能的；(3)共振散射线偏振表明，外流物质携带角动量。

The main conclusions from the works presented in this thesis can be as this: for the Galactic OH 1612MHz masers, the radiative pumping mechanism coexists with other mechanisms while some other unresolved problems need to be solved after the launch of more advanced space infrared spectrometer and the more reliable identification of the evolutionary status of the maser bearing infrared sources;the asymmetrical 53.3μm absorption line profile could become a powerful tool to assist us to observationally discriminate the radiative pumping mechanism from other pumping mechanisms in the OH masers.This is the English version of my PhD thesis.

通过本论文的研究工作，我们可以得到这样的结论：在银河系内的OH 1612MHz脉泽中，辐射抽运机制与其它抽运机制并存，而还有一些未解决的问题需要等待更先进的空间红外光谱观测设备的使用并与天体类型证认工作相配合加以解决；不对称的53.3微米吸收线轮廓特征有可能成为帮助我们从观测上对OH脉泽的辐射抽运机制加以鉴别的有力工具。

≤0.3. Second, applying a set of absorption-line indices to the Merit Function for Galactic and M31 globular clusters and the circumnuclear region of M32, we obtain their age and metallicity.

其次，将简单单星族的Lick/IDS系统谱指数应用于品质函数，给出了一些银河系和M31的球状星团，M32中心区域的年龄和金属丰度。

Applications on noise absorption of DC motor, power supply input, surge absorption of inductive load, bypass condenser, communication line protection and prevention from electricity surge were put forward because of higher performance requirement on weapon system.

针对武器系统的高性能要求，本文提出了SrTiO3基压敏电阻在直流电机消噪、电源输入端、吸收电感性负载开关浪涌、旁路电容器、通信线路防护、防止电涌冲击等方面的应用。

Since the result of FFT of FID rarely exhibits the desired pure absorption line, phase correction of FT NMR spectra becomes a necessity in NMR data processing.

由于仪器和实验条件的关系，核磁共振的FID信号经FFT变换后所得的谱线往往不是需要的纯吸收线形，NMR谱的相位校正也就成了NMR数据处理中的一个基本环节。

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.

由于辐射陷获存在，有效辐射率是自然辐射率与透射因子（发射的光子在探测区域内没有被吸收的平均概率，它与吸收截面及激发态原子密度和空间分布有关）的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子，从而得到了不同He气压下，Rb D2线的有效辐射率。
