Under normal temperature (25-30℃), the process of pollen mother cell meiosis is normal; The most of chromosomes become bivalents which like "V","O","Y","X", sticks and dots, and mainly like dots,"V" and "O"; and a few of univalent (0.79% of Tainong 1 and 0 of Irwin) and multivalent (4.76% of Tainong 1 and 3.57% of Irwin) had been observed.

常温（25~30℃）条件下，花粉母细胞减数分裂过程较为正常，双线期染色体主要形成二价体，二价体构型以&V&型、&O&型、&Y&型、&X&型、点状和棒状等形式存在，并以点状、&V&型和&O&型较多见，出现少量的单价体和多价体，其中台农1号为0.79%和4.76%，Irwin为0和3.57%；同时仅在少量中期Ⅱ和后期Ⅱ花粉母细胞中观察到落后染色体。

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。
