The results showed that the absorption of P was very low and the difference value between AME and the FHP+EADG+ECH4 was large. The extra energy were relevant to the anaerobic glycolysis and incomplete degradation of energy materials. The Brouwer equation on FHP should be amended in high altitude regions.

结果提示，西藏农区牛对P的摄入严重不足，同时AME-(FHP+EADG+ECH4)差值较大，这部分能量极有可能与高原环境物质无氧酵解或供能分解不完全有关，Brouwer方程对高海拔地区FHP的计算应进行修正。

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。

On a regular basis a long time living in the oxygenated environment of insufficient oxygen will make wrinkles come back.

定期加氧长期生活在氧气不足的环境里会让皱纹来得早。

The following is results:Under situation of hypoxia or phagocyte activated, organism produce lots of free radicals, 02~ is the most important.

其结果如下：在氧供应不足或吞噬细胞被激活等情况下，产生大量的自由基，其中最主要的是超氧阴离子自由基。

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

The hepatopulmonary syndrome occurs when intrapulmonary dilatation causes hypoxemia in cirrhosis. The free radicals may play a significant contributory role in the progression of HPS, and flavonoid agents could protect against deleterious effects of free radicals.

这个太专业了，不当之处请见谅：肺内扩张导致肝硬化部位血氧供应不足时就会发生肝肺综合症，自由基在肝肺综合症进程中可能扮演了一个极其显著的角色，类黄酮剂能够防止自由基的毒害作用。。

Potential complication: hypoxemia related to alveolar hypoventilation, intrapulmonary shunting, and V/Q mismatch

潜在并发症：低氧血症，与肺泡换气不足、肺内分路和 V/Q 失配有关

Beijing environmental problems hold severe, and atmospheric and water pollute, soil and water loss, hot island and yawp are leading problems,and take on territorial characteristic. Based on research on relativity between urban forest and these environmental problems, urban forest can effective improve environmental quality in Beijing. And for the aim of improve environmental quality, Beijing forest overlay should attain 35% at least in citywide range, and local-areas being severe environmental problem should be provided with higher forest overlay.5. Through the study on urban forest needed capacity, Beijing's forest coverage is up to par in citywide range, but montanic forest coverage, plain covered with trees and average forest area are lacking, and CO2 and O2 balance is incapable;form the point of heat and balance CO2 and O2 balance,urban forest the city zone and suburb is lack. There is urban forest developmental potential space,but the city zone and suburb area need be compensated form urban forest in circumjacent region.6. On the based of the above results and ecological network system, the author drived whole region into city area, plain and mountain area are needed at the point of planning thoughts of running-through forests and water .

根据城市森林与北京市主要环境问题的相关性分析，城市森林在改善这些环境问题中具有重要的作用，为有效改善这些环境问题，整个北京市域范围内森林覆盖率至少达到35%，并且分布比较均匀，环境问题严重的局部区域需要不同程度增加森林覆盖率。5、通过对北京市城市森林需求量研究发现，虽然在市域范围内北京森林覆盖率达到了国家标准，但是山区森林覆盖率、平原林木覆盖率、城区人均森林面积不足；从区域热平衡和碳氧平衡角度分析，城区和郊区不能满足本区域的城市森林需求量，虽然北京市城市森林具有一定的发展潜力，整体上基本可以满足城市需要，但是这些区域需要依靠周边区域城市森林的补偿。6、根据以上的研究结果，以中国森林生态网络体系建设的点、线、面布局理念为指导，以&林网化——水网化&作为优化理念，将北京市整个市域划分为城区近郊区及其辐射区域，平原区和山区三大区域，依据三大区域特点进行城市森林布局优化。
