Considering the three principles of the plant indicator for mineral exploration,namely certainty,sensitivity and feasibility,this paper evaluates comprehensively the indicating functions of the eight plants,on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore-forming element,concentration coefficient,etc.

文摘：在滥木厂和杨家湾铊矿床对芒箕、南烛、榔榆、大金发藓、蜈蚣草、石松、黄花草、醉鱼草等8种植物取样145件，在提出确定找矿有效指示植物三原则(确定性，敏感性，可行性)的基础上，依据植物灰分与底质成矿元素相关系数、植物灰分富集系数和衬度系数，较全面地分析和评价了8种植物的找矿功能；讨论了其异常的分布与断裂带、蚀变带、矿化带以及工业矿化之间的关系，并指出了其找矿意义。

CoCl2 (a chemical hypoxia-mimetic agent) was used to establish the chemical hypoxia-induced PC12 cell injuries model. Sodium hydrosulfide was used as a H2S donor. The viability of PC12 cells was measured by CCK-8 assay. The percentage of apoptotic cells was assessed by propidium iodide stain flow cytometry. The morphological change of apoptotic cells was tested by using the chromatin dye Hoechst 33258. The mitochondrial membrane potential was analyzed by rhodamine 123 staining and photofluorography. The level of reactive oxygen species in PC12 cells was measured by DCFH-DA staining and photofluorography.
