The conclusion is as follows: One of the common characteristics of overseas textbook is that they all reflect the basic concept of "structure determines property, the property of structure". The logical structure of overseas textbooks of organic chemistry is that the nature of organic compounds closely related to the theory of organic chemistry by that relationship and transformation of functional groups decide the property and reaction.

国外教材的共同特点之一是体现出"结构决定性质，性质体现结构"的基本观念，从官能团间的关系与转化来统摄有机化合物的性质及其反应，使有机化合物的性质紧扣有机化学的相关理论，构成了有机化学教材的逻辑结构。

The forward analysis of source rocks is defined as a method to estimate the amount of depositional organic matter or burial organic matter, and ulteriorly to estimate their original potential of hydrocarbon generation of source rocks by using the information of sedimentary environments, features of living biomass and physical chemistry in water medium through the geobiological analysis of geoecology, geomicrobiology, molecular geobiology and biogeochemistry. Quality and quantity of depositjonal organic matter can be calculated according to the productivity and preservation environrnents.

而正演分析则是根据沉积物沉积环境、生物物质及其介质物理化学条件特征运用地球生态学、地球微生物学、分子地球生物学和生物地球化学方法推断沉积有机质的量，甚至推断埋藏有机质的量，进而评估烃源岩的原始生烃潜力，也就是利用生物生产力和保存环境等综合分析沉积有机质的量。

The synthesis and application of Grignard reagent play a very important role in the teaching of the organic chemistry and organic experiment. The students must hold the experiment on synthesis of Grignard reagent which has been placed on the organic experimental books.

格氏试剂的制备及其应用在有机化学及实验教学中占有非常重要的地位，是学生必须掌握的一类实验，是各类有机化学实验教材中必列的实验内容。

Secondly, enrichment of 13C and 15N and their combination with NMR spectroscopy can help us study not only the dynamics of decomposition of organic materials but also the changes of their chemical structures during the turnover of the organic materials, which can provide more information in clarifying the C and N cycling and humification of the organic materials applied to soils.

本文根据已收集到的部分资料，对13C标记技术在土壤和植物营养中的应用情况作一简要综述，并在此基础上讨论了13C加富标记技术在研究植物光合作用、光合产物的去向以及标记秸杆在土壤中的分解等方面的应用及其注意点，旨在能为国内开展这方面的工作提供十分有用的参考

The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

结果表明，在本试验条件下，基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好；基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降，与对照的DNA序列相似系数最低；有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。

There are three categories of maturity indicators of organic matter in current petroleum industry to evaluate the degree of thermal evolution for source rocks, including: 1 optical indicators, i.e., vitrinite reflectance, bitumen reflectance, sporopollen color and thermal alteration index, conodont color alteration index, and reflectance of fossil fragments; 2 chemical indicators, i.e., the maximum temperature in pyrolysis of organic matter, methyl phenanthrene indicator, the atomic ratio of H/C, carbon isotope indicator, and biomarker indicators; 3 indicators of spectroscopy, i.e., the free radical concentration of kerogen, the average structural scale of aromatic nucleus of kerogen, and the laser-Raman spectrum of organic carbon.
