And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.
因此,再次将"板溪群"是否是前震旦纪的一个变质地层单位、江南古陆是否存在以及华南大地构造格局是否需要重新厘定等问题提了出来。1993年笔者于赣东北蛇绿混杂岩带内的"双桥山群"岩块中,首次发现了含晚古生代的放射虫硅质岩。1996年又在该混杂岩带多处的"双桥山群"岩块和"下震旦统志棠组"中找到了含晚古生代的放射虫硅质岩,还首次在"登山群拔竹坑组"中发现了早古生代的几丁虫化石。

On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.
本文在大量测试工作基础上,利用煤岩学与有机地球化学资料,分析了煤系油气的来源,认为本区延安组煤系煤层生油潜力差,煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生,油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系;通过对煤层及围岩一系列物性参数的测试,分析与评价了煤岩层的生、储、盖、渗性能与可抽放性,得出主采4_(-2)号煤层属中等储集、低渗透层,围岩封闭性差,渗透性高,煤层瓦斯含量低,而顶板砂岩瓦斯含量高,为采面瓦斯涌出的主要来源。

The compatibility of both Gvirens and B.firmus was researched. The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.
