The average body weight of each silkworm is 1.174 g, 1.116 g, 0.975 g and 0.862 g, respectively. The body weight decreases along with the increase of radiation dose. The body weight of 20 Gy and 30 Gy groups have remarkable difference compared to comparison and the 10 Gy groups (P.01). Cocoon shell rate show no significant difference among 10 Gy and the 20 Gy radiation groups and the groups control farm plot comparison. They are 23.37%, 23.54% contrasts 24.25%, respectively. Yet the 30 Gy dose is 21.74%(P.05). The number of eggs laid per spawn first rise then fall, from 529 grains of control farm plot to 540 grains of 10 Gy and 392 grains of 30 Gy. This possibly is the exposure of radioactive rays causes the change of silkworm's growth mechanism, causes the damage of cellar membrane and changed protein structure, and also has an influence to silkworm's digestion function.
四龄第2天随机称量50头蚕，对照、10 Gy、20 Gy和30 Gy区每头蚕平均体重分别为1.174 g、1.116 g、0.975 g和0.862 g，体重随剂量增加明显减轻，其中20 Gy和30 Gy区对比对照和10 Gy区均有极显著差异；茧层率在10 Gy和20 Gy辐照区与对照区比较变化不大，即23.37%、23.54%对比24.25%，而30 Gy辐照区显著降低，为21.74%；单蛾产卵数先升高后降低，从对照区的529粒到10 Gy的540粒和30 Gy的392粒，这可能是辐照使蚕生长发育的机制发生了改变，引起膜损伤、破坏蛋白质的结构的原因，并且对蚕的消化功能也产生了影响。
Interlayer oxidized zone can be divided accurately by Fe_2O_3, Fe_2O_3/FeO and U parameters. We can correct the field macroscopic color zoning by combining the macroscopic zoning and microscopic zoning. Univalent major elements components(Al_2O_3, SiO_2, K_2O, Na_2O) show remarkable activity at the process of interlayer oxidizing, their contents are variable and mingled in different zones and it can't be used in zoning. But we can speculate the developmental degree of interlayer oxidized zone and uranium mineralization according to the concentration trends and variation characteristics of sensitivity group, activity group and their ratios.(3)The comparatively steady elements such as lithiphile elements, sulfophile elements and high field strength elements change regularly at the process of interlayer oxidation except some radioactive elements. Trace elements and rare earth elements commonly enrich in thin rock clast such as mudstone, in which the enriched elements species are more than those in the whole rock, which indicate that the regeneration action in caulking matter are more deep than that in whole rock at the process of interlayer oxidation, and the reallocate intention of trace elements in main minerlized rock in Tuha basin are more intensive than that in Yili basin at the process of deposition, diagenesis and later changes.
根据化学蚀变参数PC值和分离迁移位等将常量元素组分分为敏感组分组、活动组分组、次活动组分组和惰性组分组，不同组分可分别用于讨论层间氧化带低温地球化学中不同问题；敏感组分(变价元素组分Fe_2O_3、FeO)和U在层间氧化带中迁移富集规律明显，Fe_2O_3／FeOFe~(3+／Fe~(2+)比值具分带判别能力，配合U含量对层间氧化带进行较准确的分带，可克服野外宏观颜色分带偏差：提出Fe~(3+)／Fe~(2+)分带判别值在不同盆地、不同地段不同，除受氧化作用控制外，流体酸碱度不同也是重要因素的观点，对找矿实践有实际指导意义；活动组分(Al_2O_3、SiO_2、K_2O、Na_2O)在层间氧化作用过程中具有较明显的活动性，其含量值变化跳跃，在不同分带相互交织，不具分带指示意义；但利用敏感组分、活动组分及其比值在层间氧化带中的变化特征可推测层间氧化带发育的完善程度及其含矿性；次活动组分组(CaO、MgO、MnO_2)含量低，变化规律性差；惰性组分组(TiO_2、P_2O_5)含量低，活动稳定，可用来反映沉积物源特征。
This paper presents and summaries the application of stable and radioactive carbon isotopes (δ13C and 14C) in the regeneration of longterm carbon dynamics process of ecosystem(such as the historical pattern of C3/C4 vegetation) and in SOC cycling. The application of isotopic techniques in the studies of SOC source and cycling, soil CO2 flux change and component difference, isotopic enrichment, etc. is also discussed. In addition, the fundamental issues related to SOC dynamics are outlined and the major topics for isotopic tracer of SOC dynamics in future are proposed in the paper.
