Considering many biophysics processes such as the atmosphere,hydrology,plant leaf N content et al.a multiple layer,two-leaf canopy model for predicting of mass transportation and energy exchange between plant canopies and the atmosphere has developed after dividing the canopy height into three layers,and the sunlit and shaded leaf area index was computed respectively at different layers through introducing a foliage clumping index,it is important to distinguish the spatial light distribution and so leaf photsynthesis.

多层—双叶模型对冠层上方碳通量的模拟：综合考虑农田水、热因子及叶片氮含量的非线性垂直分布对碳、水循环的影响，将农田按植株高度分为上、中、下三层，并通过叶片集聚指数计算阴、阳叶面积以区分叶片的空间分布受光状态，建立了均匀农田与大气间物质输送和能量交换的多层—双叶模型，对农田冠层上方基于光合—呼吸的碳循环过程进行了模拟应用研究。

The results indicated that OC in crop root and stubble was available for balance of soil OC in plough horizon, but was not enough generally as only mineral fertilizers were supplied. With no fertilizer, the biomass and the amount of OC of crop root and stubble both decreased year after year.

试验结果还表明，根茬有饥碳对维持耕层土壤有机碳的平衡有相当大的贡献，但在单施化肥时大多不足以补充矿化消牦；在不施肥时，根茬生物量和有机碳量均逐年下降。

On the other hand, steam can be used to restrain the side reaction such as hydrogen transfer reaction so as to increase the yield of light olefins by diluting the concentration of the reactant. In addition, minor steam can react with the feed hydrocarbon resulting in the decrease of coke and the formation of active hydrogen without the increase of hydrogen gas and light saturates that is not desirable.

另一方面，水蒸气不仅仅具有降低烃分压的作用，抑制了氢转移反应等副反应，对于低碳烯烃的产率有好的影响，而且在反应过程中，少量参与了反应，与烃类发生了水煤气反应，生成了活泼氢，不仅降低了焦碳的产率，并且没有提高氢气、低碳烷烃等不希望得到的产物。

Carbon is easier to react with steam than α-carbon, therefore adding a small amount of steam in feed gas can obviously suppress β-carbon deposit.

碳比α-碳更容易同水蒸汽作用，添加少量水蒸汽到反应气中能够明显抑制β-碳的生成。

The latter could be eliminated more preferentially than the former by steam, so the amount of the latter was obviously suppressed by adding steam in feed gas.

碳比α-碳更容易同水蒸汽作用，故水蒸汽的添加能够明显的减少积碳。

A Ni/Ce-Zr-Al-Ox catalyst was prepared by hydrothermal synthesis－impregnation method. The CO2 reforming of CH4 reaction was performed. By XPS and TPH methods the carbon species deposited on the surface of catalyst during the reaction were characterized; The effect on the carbon deposit by adding a small amount of steam in feed gas and the interaction between steam and carbon species were studied.

Kinetics and reduction characteristics of two iron-bearing materials are investigated to understand the self-reduction process as well as to verify some parameters in calculation.(1) The compression strength of wet pellet and dry pellet is kept to 10N/P and 23N/P respectively and the wet pellets impact to 11 frequencies/pellet in the process of pelletmaking.

作为对流程模型某些参数的验证以及对还原过程加深了解认识，本文进行了两种含铁原料—转炉尘泥和铁精矿粉固碳还原实验研究及其还原过程动力学研究，主要研究成果如下：(1)尘泥含碳球团湿球和干球抗压强度为10N／个和23N／个，低于精矿含碳球团，湿球落下强度14次／个，高于精矿球团。

Type shown above, the lower temperature as allyl methyl carbocations (1) is greater than the stability of carbocations (2), so the potential energy diagram in the reaction pathway for the carbon embodied in the positive ion hybrid resonance body and Chloride Cl-if by 1,4 - addition will have to experience higher ...

如上式所示，较低温度下由于烯丙基甲基碳正离子(1)的稳定性大于碳正离子(2)，所以在反应历程势能图中体现为碳正离子共振杂化体与氯离子Cl-若按1，4-加成则要经历较高。。。
