Focusing on the PGE enrichment mechanism in the basic-ultrabasic intrusions in the Panxi rift, firstly, through the interpretation of TM photograph, data processing of regional geochemical exploration and geophysical prospecting results of gravity, magnetic force and seism, we analyzed the controlling effect of structure and magmatic movement on the PGE mineralization; Secondly, through the study of volcanic apparatus, petrography, measurement of comprehensive geochemical section, isotope tracing and dating of typical PGE-rich melanocratic rock series, we discussed the sources of the PGE-bearing mafic-ultramafic intrusions and basalts, their timing, evolvement sequences, the geochemical processes of magma crystallization and fractionation, and the relationship between magma evolution and structural development; Finally, through the analysis of PGE and chalcophile elements concentrations in the melanocratic rock series and the contrastive study with the Noril''sk magmatic Ni-Cu-PGE sulfide deposit, its related continental flood basalts and Siberia Traps, we discussed PGE mineralization characteristics and its enrichment mechanisms in the melanocratic rock series in the Panxi rift.

The results show that the modificator Mg can cause thermodynamic undercooling , and it may absorb in the crystal faces of preferential growth of carbides, which can slow down carbides growing up on plate type and make them tend to be fine, isolated and passivated, and thus the impact toughness is improved greatly.

研究结果表明：在过共晶高铬白口铸铁结晶过程中，变质元素Mg不仅造成热力学过冷，而且Mg可能吸附于碳化物择优长大的晶面上，起到阻碍碳化物片状长大的作用，使碳化物趋于细小、孤立，且边部钝化，使冲击韧度显著提高。

The electromagnetic force opposite to the fluid flow is also produced, which makes less impact on the narrow side shells, and results in a pluglike flow in the region under the lower pole of the magnetic field.

计算结果表明，结晶器内流动的钢液在恒稳磁场的作用下，形成了具有封闭回路的感生电流，其主体部分从板坯宽面一侧大范围地向另一侧流动，中途逐渐变大，并绕过水口流动。

The maximal reaction rate of pyrotechnical reagent with potassium perchlorate added with Fe2O3 by crystallization method is 8.10 min-1, which is 4.09 times of that without catalyst. The time to maximal rate is 8.52 min, which is lower than that without catalyst by 92.8%. It was also found that CuO can catalyze pyrotechnical reagent with potassium nitrate, and the addition is better with mixing method.

结果表明，氧化铁对含高氯酸钾的烟火药剂具有催化作用，以结晶添加法催化效果最佳；此药剂的最大反应速率为8.10 min-1，是不含催化剂药剂的4.09倍；到达最大反应速率时间为8.52 min，比不含催化剂的药剂降低了92.8%。

Meanwhile, the surface layer gets fine crystal grain with dispersive and homogeneous distribution of WC grains and Co binder from rapid melting and resolidification during HIPIB irradiation. Minimizing the mean free path in Co binder by decreasing the WC grain size leads to an increase in resistance to plastic deformation in the binder.

HIPIB强烈非平衡作用下的重熔和再结晶使WC晶粒细化且分布更均匀，同时，表层析出弥散分布的Co_3w_9C_4相，使Co粘结相产生强化，导致Co粘结相的平均自由程降低，从而增强了Co粘结相抵抗塑性变形的能力，提高了辐照硬质合金的耐磨性能。
