The results show that Re-K-Zn compound modificator has remarkable effects in high Chromium white cast iron when the modificator has 0.5%Re+2.0%K+0.008%Zn. The modificator not only or bar-like carbides but also improved the mechanical properties of high chromium white cast iron,with its impact toughness enhanced from 7.0J/cm2 to 11.7J/cm2 and its hardness enhanced from 54HRC to 57HRC, and the wear resistance increased by 350%.

实验结果表明：Re-K-Zn复合变质剂在高铬白口铸铁中有显著作用，而且当三者的加入量约为0.5%Re+2.0%K+0.008%Zn时，能显著细化组织，使其组织中网状碳化物变为粒状或条状，提高了高铬白口铸铁的力学性能，铸态冲击韧性由原来的7.0J/cm2提高到11.7J/cm2，硬度由原来的54HRC提高到57HRC，相对耐磨性能提高了3.5倍。

It was demonstrated thermodynamically that the initial products with respect to the uranium-hydrogen system included UH, UH2, UH3, U2H2 and U2H4. The potential energy surface analyzing results confirmed that the optimized structures and suggested, theoretically, that the main initial products were UO or linear U02 in the uranium-oxygen system, and uranium monocarbide or uranium oxycarbides in the uranium-carbon monoxide system, depending on the different interaction mode.

计算结果从热力学上证明了铀与H_2的初始反应产物可能有UH、UH_2、UH_3、U_2H_2和U_2H_4 等；随着铀与O_2相互作用的方式的不同，铀氧化的初始产物或者是UO分子，或者是直线型UO_2分子；CO在铀上的吸附属于解离吸附，并以CO的碳端与铀原子相互作用最有利，初始相互作用产物主要有碳化物和碳氧化物。

When the retained austenitic content is lower than 10%,the wear resistance will be reduced greatly due to in situ transformation of_(23)C_6 to M_3C and pearlitic structure forming.

当残留奥氏体含量低于10%时，由于23C6发生向M3C型碳化物的原位转变，相应的组织转变为珠光体，导致耐磨性急剧下降。
