By use of the Fischer-Tropsch reaction in a C-H-O system, we discussed the relationships between inorganic CO〓 and some physical chemistry conditions, such as Oxygen flee degree , temperature, pressure, other objects consistency and catalyzer. a when T=200K~2000K, if f〓>0, the reaction of generating CO〓 will be dominant, CH〓 hardily exists; b when T>1000K, CH〓 is not propitious to exist, carbon in system almost exists in form of CO〓; c the more pressure, the more CO〓 is propitious to exist; d the more consistency of CO, O〓 and H〓O, the more CO〓 is propitious to exist, the more consistency of H〓, the more CH〓 is propitious to exist.

依据C-H-O体系费托反应的简化模型,讨论了氧逸度、温度、压强、其它物质浓度、催化剂等物理化学条件对无机成因CO〓生成的影响,从理论上讨论了在地质环境中,无机成因CO〓存在的物理化学条件:1在T=200K~2000K的温度范围内,体系中一旦氧逸度>0,生成CO〓的反应将占绝对优势,CH〓几乎不可能存在;2T>1000K时,不利于CH〓形成,使体系中的碳主要以CO〓的形式存在;3体系压强越大,越有利于CO〓的形成;4反应物CO、O〓、H〓O的浓度越高,越有利与CO〓的存在,H〓的浓度高有利于CH〓的形成。5地质成藏作用可以经历很长的地质年代,这足以补偿矿物岩石中的Ni、Mo、Fe、Co、Ru等催化性能的降低及其它动力学条件的不足,使得费托反应可能发生,从而生成无机成因的CO〓和烃类。

In the first part, we will first deal with the strong Bonnesen-style inequality (2.1.3) for closed convex curves in the plane (the numbers of formulae and references are those of them in the context below). Bonnesen had first proved the weaker inequality (2.1.2) in [12] and several years later, he outlined in his monograph [13] various Bonnesen-style inequalities including (2.1.3), he considered, however,(2.1.3) as a direct consequence of Kritikos theorem for convex bodies in higher dimensional Euclidean spaces,. Here, we will give an independent proof of the existence for inequality (2.1.3), and by the way, give an estimate on the width of the bi-enclosing annulus of closed convex curves in the plane.

In this dissertation, InGaAs/InGaAsP/InP MQW microdisk laser and its characterization were presented. Some conclusions are as following: the characteristics of lasing threshold was discussed by using rate equation. The dependent relations between threshold and cavity volume, spontaneous emission coupling efficiency β were investigated. The whispering gallery mode and spontaneous emission in a microdisk geometry were then studied. Almost all spontaneous emission was coupled into the lowest order TE mode when the normalized thickness of photonics well was between 0.15 and 0.5. The design principle and device process of InGaAs/InGaAsP/InP MQW microdisk laser were presented. The microdisk lasers with the diameter of 8μm, 4. 5μm and 2μm were succesfully fabricated by using etching techniques. The pulse lasing thresholds for the microdisk with the diameter of 8μm and 4. 5μm were 170μW and 15μW, a record results compared with the published in the literature. The cw lasing threshold for a 2-μm-diameter microdisk was only a few μW. We haven't found similar report up to now. To solve the problem of directional output in a microdisk laser, the power coupling efficiency in a double disk geometry was investigated with the theory of waveguide mode couple. A new structure of electrically pumped microdisk laser with output waveguide was designed, making a foundation for the practical use of microdisk laser.
