Benzaldehyde nitrogen mustard isonicotinoyl hydrazone was synthesized according to literature method. The copper , cobalt , nickel , chromium , iron , zinc and cadmium complexes of it were prepared and characterized by elemental analysis, IR, UV-vis, NMR and EPR spectra. The cytotoxicity effect of the complexes was examined on SMMC-7721 cell line. Results show that the complexes have definite antitumor activity and the synergic effect between chromium and the ligand.

依照文献合成了异烟肼苯甲醛氮芥腙及其铜、钴、铬、镍、铁、锌和镉配合物并用元素分析、红外、电子光谱、核磁共振及电子顺磁共振光谱，对这些配合物进行表征，确认了它们可能的立体结构，并研究它们对SMMC-7721人肝癌细胞的作用，结果表明它们均有一定的抗肿瘤作用，发现铬与配体存在有协同作用。

The results show that the addition of certain manganese in high chromium cast iron leads to a re-partitioning of alloy elements between austenite and carbide and a dropping in equilibrium phase transformation temperature although it's inappreciable for the influence of manganese on mass fractions of every phase in this cast iron. There is about 87 percent ledeburite under thermodynamic equilibrium condition and 23 to 32 percent M7C3 type carbide under thermodynamic non-equilibrium condition in the microstructure of 3C-l5Cr-4Mn-0.75Si system high chromium cast iron. Furthermore, the improvement of austenite stability and hardenability of manganese alloyed high chromium cast iron may been expected because there is a substitution between manganese and chromium that has been suggested by thermodynamic calculations.

结果表明，锰虽然对高铬铸铁中的各相数量影响不大，但一定数量的锰存在促使合金元素在奥氏体和碳化物两相中的重新分配，并降低平衡相的转变温度；在平衡条件下3C-15Cr-4Mn-0.75Si系高铬铸铁中菜氏体数量约占87%，而非平衡条件下M7C3型碳化物数量在23%-32%之间，且奥氏体中锰铬互替现象保证了奥氏体的稳定性和加锰高铬铸铁的淬透性。
