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。

As a finite existence, human also want to purchase infiniteness and perfection, during which human find his value and richness: finiteness and infiniteness, shortage and perfection, etc., social existence is human\'s living circumstance, the generation of it is man and society\'s generation, also social development promotes human\'s full and free development and proves his essence. Contemporarily, as historical existence, history is a successive unity just like human practice.
人作为有限的经验的存在物,决定了对于无限性与完整性的追求,人的存在的时间过程正是人在有限性存在中的无限开放,而人在有限与无限、缺憾与完美的张力中感受到了自身生命的存在和生命的意义,因而人在对于生命的意义和价值的体验中感受到了社会时间的存在;社会存在和历史的生成成为人的生存境遇,劳动产生了人类社会,劳动时间促成了社会存在的生成,而社会历史又是基于对交往、对话和历史理解中的时间差的弥补中而得到发展。

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.
胰岛素耐受实验和胰岛素敏感指数表明OP动物的胰岛素敏感性较OR动物下降,而OP大鼠血清中游离脂肪酸、酮体、肝脏总胆固醇和甘油三酯水平显著升高;但是,OP与OR大鼠血清中总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白和空腹血糖等的水平并无显著性差异;⑶肥胖易感与肥胖抵抗大鼠血清、尿液和肝脏组织提取物中代谢物的比较研究表明:①OP与OR大鼠的血清、尿液和肝组织提取物中多种氨基酸的含量存在显著差异,并以肝组织中的差异氨基酸数量为最多,包括各种生酮和生糖氨基酸水平在OP组的升高,说明氨基酸代谢的差异是两种体重表型大鼠之间存在的重要差异特征之一;②OP与OR动物肝脏和血清差异代谢物中包含多种饱和长链脂肪酸的升高如十四烷酸、十六烷酸、硬脂酸等和多不饱和脂肪酸的下降如亚油酸和花生四烯酸,说明两种体重表型动物的肝脏脂肪酸代谢存在明显差异;③长期高脂饮食喂养后,动物的尿液代谢物分析表明OP与OR动物体内的肠道菌群结构存在差异,这些菌群上的差别可能在动物体重增长的调节上产生影响;④与OR动物相比,OP动物尿液代谢物中儿茶酚胺类递质的代谢终产物如高香草酸、扁桃酸和4-羟基苯乙酸明显升高。
