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。

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.
发现在α位具有-OH、-SH等取代基的短链一元羧酸(乳酸、羟基乙酸、巯基乙酸,葡萄糖酸)对赤铁矿与钠辉石的浮选分离具有优良的选择性抑制作用,-OH、-SH的-I诱导效应导致有机酸的pKa值下降并落在两种矿物零电点之间,使其抑制性能增强,并与矿物表面的Fe〓形成稳定的五元螯合环。

The energy-rich intermediate anions, eg. [CH2=C—OH]- as the initial product of the insertion reaction and [CH2=CHO]- as the direct bonding product, are able to isomerize and decompose to various final products, such as C2H-+H2O, CH2C+OH- and CH3-+CO.
其中, 通过插入反应形成的富能中间体[CH2=C—OH]-及键合中间体[CH2=CHO]-都可以进一步经异构化和解离生成其它各种可能产物,如C2H-+H2O, OH-+CH2C和+CO产物通道。

METHODS: A dose-response relationship of 8-OH-DPAT, spontaneousphrenic nerve activity and a nociceptive C-fiber reflexwere established simultaneously in an in situ perfused, nonanesthetized,rat brainstem-spinal cord preparation. Fentanyl was administered in situ to investigate the interaction with 8-OH-DPAT on phrenicnerve activity and nociceptive CFR.
