The carbon isotope composition of single alkanes (δ13Cia) in two plants (Leontopodium leontopodioidies and Taraxacum mongolicum ) growing in the northeastern Qinghai-Tibet plateau was analyzed by means of GC-IMS in order to know its relationship with altitude,and furthemore, to gain new data for the research on climatic changes.

用色谱—同位素质谱仪对青藏高原东北部高寒草甸生态系统中的两种高等植物—火绒草和蒲公英的烷烃进行分析，讨论环境因素对植物单体烷烃碳同位素组成（δ13Cia）的影响。

Chemical treatments could efficiently decrease the amount of waxiness, the cellulose, semi-cellulose and silicon dioxide of raw rice straw, while water-soluble compounds of the treated rice straw was increased and therefore the treated straw could be easily attacked by soil microorganisms.

在此基础上，本文通过小麦和菠菜盆栽试验，研究了经过化学处理的水稻秸秆与氮肥配施对土壤微生物量碳、氮、矿质态氮(NO_3~--N+NH_4~+-N)的动态变化以及作物生长的影响，获得以下研究结果： 1。

Three new ferrocenylmethyl-substituted indenes and cyclopentadienes were synthesized by the addition of hydrogen anion and carbon anion to fulvene and benzofulvene respectively, moreover, their structures were characterized by NMR and MS.

Arbuscular mycorrhizal symbiosis is the mutualistic association between AM fungi and most terrestrial plants: the plant roots offer carbohydrates to the fungi; in return, the fungi assist the plants with uptake of mineral nutrients, particularly phosphate, from soil, and their subsequent transfer to the root cortical cells.

南京农业大学资源与环境科学学院，南京 210095摘要丛枝菌根(arbuscular mycorrhizal， AM)共生是丛枝菌根真菌与大多数陆地植物的根系之间形成的一种互利共生关系。植物给菌根真菌提供碳水化合物；作为回报，菌根真菌能够增强植物对矿质营养元素的吸收。

The results were that sucrose and glucose were two good carbon sources which could support the growth of Roselle cell, but soluble starch could not be assimilated by Roselle cell, and other nutrients assimilation by Roselle cell were far slower than that of two above carbon sources.

结果表明，蔗糖和葡萄糖在这些方面的表现基本相同，而可溶性淀粉由于植物细胞对其没有有效的水解利用手段，因而不能支持植物细胞的生长，从基质消耗水平上来看，也明显慢于上述两类碳源。

The mineralogical and geochemical research on grey-brown laminatedmud stone, oil shale of Shahejie Formation Member 1 of Gulan Subsag found that the content of sapropel was all over 97% and the content of organic matter and chloroform bituments "A" was over 1% and 0.1% respectively in 35 samples. The organic matter belonged to type I and reached the standard of good source rocks.
