This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.

It was found that PLZT was easily reduced and the thickness of reduced layer had a linear relationship with the reduction time; The optimal conditions for PLZT were determined to be 950℃ for 1~5 hours; Reduced PLZT was composed of reduced and unreduced layer obviously and the reduced layer was transgranularly fractured while the unreduced ceramic was intergranularly fractured; Metallic lead and refractor oxides (PbO, ZrO2, TiO2, etc.) were found in the reduced layer, however, the crystal structure of PLZT was not found.

研究表明，PLZT具有较好的还原性能，还原层厚度与时间有线性关係，理想的还原条件为：950℃保温1~1.5h；还原样品有明显的分层结构，还原层表现出穿晶断裂而未还原层则是沿晶断裂的特徵；还原层主要由金属Pb及PbO， ZrO2， TiO2等氧化物组成，原先的晶体结构已不存在。

We approach the problem based on the perception that electric field induced microstructure evolution at the crack tip will lead to fracture and fatigue. It follows that a micrograph of intensified electric field induced domain switching at the crack tip is obtained, a theoretical model of domain switching induced fracture is proposed, and the failure mechanisms of electric fracture, electric fatigue and crack kinking are revealed.
