This effectively controls the air pollution caused by incinerating.

但是被粉碎还田的秸秆，混杂在土壤中照样会腐烂、产生甲烷，和被还原性微生物释放成二氧化碳。

In this paper, the method of growing carbon nanotubes bycatalytic decomposition of 〓 in low temperature on apowder Ni-Mg-O catalyst system is used. By controlling thereaction conditions and catalyst precursor, we preparedifferent configuration of carbon nanotubes and discuss themechanism of carbon nanotubes growth, we firstly researchthe character of lithium ion intercalating carbon nantubes,and reach some important conclusions.

Chapter 1 mainly reviews the evolution of methane catalyzed by ligated transition metal.

第一章，综述了金属配合物阳离子活化甲烷的反应研究进展及本文主要工作。

Formaldehyde, methanol and methane have been utilized as methylating agents.

甲烷、甲醇和甲醛可用作反应的甲基化试剂。

Therefore,we try to directly couple the endothermic reaction of long chain alkane dehydrogenation with the exothermic reaction of methane catalytic combustion by using the metallic monolithic catalysts,which highly miniaturizes reactor size and significantly increases heat efficiency.

因此，本文以长链烷烃脱氢和甲烷催化燃烧为模型反应体系，利用金属基整体式催化剂将上述吸热与放热催化反应直接进行热耦合，以期实现工艺过程的高度集成并提高热利用效率。

And methane, though it burns more cleanly than coal, absorbs a wider range of wavelengths of the Earth's outgoing radiation than CO2. It therefore traps more heat, making it an even more pernicious greenhouse gas.

而且虽然甲烷燃烧起来比煤更清洁，但它吸收地球发出的辐射线的波长，比CO2吸收的范围更广，因而它吸收更多的热量，使得它成为一种更有害的温室气体。

The COD of strength organic wastewater can be removed more satisfactorily with steady operation of the anaerobic reactor by immobilized Methanosarcina than that by free cells.

在处理高浓度有机废水过程中，固定化甲烷八叠球菌能加快对厌氧反应器的启动，比游离细胞具有更高的反应效率且反应比较稳定。

To determinate the concentration of TiO_2 in functional fiber for labeling purpose,the sample was nitrified with burning and dissolved in mix acid as pretreatment and then its concentration of TiO_2 was determined by spectrophotometric method with ascorbic acid as shelter reagent of Fe~(3+) and Cu~(2+) and diantipyryl methane as developer at wavelength λ=390 nm.

针对功能纤维中添加TiO2的含量测定问题，对功能纤维样品采用高温消化、混酸溶解的前处理方式，以抗坏血酸作Fe3+、Cu2+的掩蔽剂，二安替比林甲烷作为显色剂，用分光光度法在λ=390 nm波长处测定功能纤维中纳米TiO2的含量。

Based on the study of rock textures and structures, and stable isotopes of dolomite and S isotope of barite interlayers within the cap dolomite outcropped in the Miaohe area in the Three Gorge, it is testified that the stable isotopes show a strong negative excursion, and the isotopes of sulfur show a significant positive excursion, which is similar to the reported data of authigenic barites formed in a modern seafloor gas hydrate environment. Therefore, it can be concluded that the cap dolomite was most likely formed in a special environment under which a huge gas hydrate dissociated with the breakup of "Snow Earth" in later Neoproterozoic.

通过对湖北三峡庙河地区出露的&盖帽&白云岩的野外地质构造、碳－氧稳定同位素和重晶石夹层的硫稳定同位素特征的研究，发现除了明显的碳稳定同位素的负偏移之外，重晶石的硫同位素值表现出明显的正偏移，其数值可与现代海底甲烷喷气孔附近的自生重晶石矿物的同位素组成相对比，进而认为&盖帽&白云岩的成因是末元古代&雪球&事件之后天然气水合物的释放与全球环境突变背景下的沉积产物。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
