The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.

The analysis results indicate that the vibration fractional factor with rotating frequency has a close relationship with both rotating speed of rotor and damping of bearing under constant acceleration. When rotating acceleration is small and damping is large, the transient response is not sensitive to the variation of rotating speed; otherwise the imbalance response with constant acceleration and the response in stable state will build up obvious differences near critical rotating speed.

研究结果表明：在恒加速条件下，转子同频振动分量与转子的转速、支承阻尼等因素密切相关，当角加速度较小且阻尼较大时，其瞬态响应对转速的波动不敏感；而当角加速度较大或阻尼较小时，恒加速过程不平衡响应与稳态响应在临界转速附近将产生明显的差异。
