By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.

Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.

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。
