浓度信息

In data processing, polybasic statistics and geological statistics were combined to acquire information in concentration lining degree, structure, fabric and analogism. At the same time,anomalous boundary was determined by simulation and the quantitative evaluation method for geochemical exploration anomalies was also discussed.

在数据处理上，将多元统计与地质统计法相结合，提取浓度、衬度、结构、组构、类比等多方面的油气信息，运用模拟技术确定异常边界，并探讨了化探异定量评价方法。

The results showed that the microbial community could degrade 39.6% of rice straw gross weight within five days. When the culture medium volume was 1/5 of the whole and pH at 6 on the 5 days culture, the CMC reached the highest of 14 IUml^(-1). During the rice straw degradation, more than ten kinds of products were detected using GCMS. DGGE detected the dynamic change of microbial community composition, and the microbial composition changed greatly in different periods. The phylogenetic tree derived from 16s rDNA sequence was found that the closest relatives belong to Clostridium sp., Brevibacillus sp., Bartonella sp.、Bacteroidetes sp.
