On the presentation of Mn-P fixation, this paper reviews the latest advances in recent 10 years and concentrates on the mechanism of phosphorus fixation in acid soils. In addition, it brakes through the classical inorganic P fractionation in to Fe-P, Al-P, O-P and Ca-Pin the traditional P classification and considers Mn-P as one of the main phosphorus fixation modes in latosols, cultivated from the parent basalt material. Furthermore, fixation of P by Fe, Al, Mn is compared, and differentiation from chemical availability and bioavailability of P discussed. Based on the above, this paper presents some alienable measures for enhancing P utilization efficiency and postulates pivotal future research directions in the field of P fixation.

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.

结果表明：在氧化条件下，缺陷导致Al的内氧化，在1100℃时，由于Al的大量内消耗，涂层表面已不能形成单一的氧化铝膜，使氧化性能下降；在热腐蚀条件下，缺陷成为硫向涂层中扩散的通道，导致涂层及基体的硫化；在冷热疲劳条件下，缺陷成为裂纹源，在交变应力作用下，裂纹向基体中扩展，降低了涂层的热疲劳性能。

The results show that the white thick-bedded siliceous rocks have high contents of SiO2 and Al2O3 and high ratios of Al/ and Al2O3/(Al2O3+ Fe2O3). The ∑REE are low, and the North American shale-normalized REE patterns are characterized by enrichment of LREE and absence of Eu and Ce anomalies, which suggest that the white thick-bedded siliceous rocks might have been formed in the continental margin environment and affected significantly by terrigenous constituents. The anatase-rich siliceous rocks have high contents of TiO2, Fe2O3, Cu and V but low Al/(Al + Fe+ Mn) and Al2O3/(Al2O3 + Fe2O3) ratios. The ΣREE are high, the North American shale-normalized REE patterns are obviously characterized by left-oblique to flat styles of curves and slight negative Ce anomalies, implying that they might have been formed in an oceanic ridge environment.
