: By means of kerogen purification, the proton induced X-ray emission (PIXE) and instrumental neutron activation analysis (INAA), the authors have studied the organic/inorganic occurrence modes of the metallic elements of the Baiguoyuan silver-vanadium deposit hosted in black shale in Hubei Province, China. The result shows that Au, Hg and Ta have a strong tendency to occur organically, with more than 70% of these elements being associated organically. Se, Ga, Ag and Hf are partly associated with organic matter, with more than 20% of them occurring organically. Compared with the above elements, Zn, Cu, As and Sb are weakly associated organically, and tend to be enriched in kerogen. However, Mn, Th, U, V, Co, Cr, AI, Fe and Sc usually occur inorganically. Of the rare earth elements (REE), La, Ce, Tb, Dy, Yb and Lu have stronger ability to be associated with organic matter than Sm and Eu.

在质子X荧光(PIXE)分析的基础上发展起来的扫描质子微探针(又称质子显微镜),是离子束分析技术中的一个重要分支.自从1970年***等人在质子显微镜方面的开创性工作以来,许多国家的有关实验室纷纷竞相研制,特别是1978年以后,发展迅速,迄今为止,全世界已有25台质子显微镜(束点直径≤20μm). 采用磁、电聚焦系统或者针孔限流器,把加速器产生的质子束收缩成为很细的质子微束,对样品进行扫描分析,就可以获得样品表面元素的分布图象.同一般的PIXE分析相比较,质子显微镜不仅能给出样品中元素的种类和含量信息,而且能给出元素在样品表

作者： ZHANG Yue-li1, LIU Kai-qi2, XIANG Mei-mei2, LIU ren2(1. College of Plant Protection, Shangdong Agricultural University, Taian 271018, China. 2. Dept. of Resource and Environmental Science, Zhongkai Agrotechnical College,Guangzhou 510225, China)

One hundred and fifty one isolates of Trichoderma were collected mainly from more than 40 soil samples and other materials in Guangdong Province (including chigang, Zhanjiang, Wuchuan, Panyu, Zhaoqing, Dongguan, Humen, Qingyuan, Guanzhou) and the soil samples were also from different plant rhizosphere (including rice, different fruits and different vegetables). It was shown that 39 isolates of Trichoderma grew faster than other isolates using growth velocity experiments. The 39 isolates could effectively inhibit Fusarium oxysporum ***. cubense (***) Sny.&Hans. by dual cultural experiments. The inhibited activity included the antifungal activities of its metabolite, mycoparasitic activities and the lytic enzymes by dual culture, electronic microcopy and enzyme assay. At present, studies on the taxonomy of the 151 isolates of Trichoderma are carried out in our experiments, some Trichoderma species aggregates will be identified according to the taxonomy system revised by Rifai and Bissett.
