In regard of the deposition coating way , the results of experiments show that ph value have no influence on the coat layer forming . under different ph value in these experiments , graphite surface ca n ' t be coated mostly . just on some surface of graphite , is there the flaky coat layer deposited 沉淀包覆工艺改性研究结果则表明：沉淀法对ph值的选择性较小，在本试验选择的ph值范围内，石墨表面大部分没有被包覆，只有小部分表面有局部富集的絮状覆层物质沉积，包覆均匀性差。
By analyzing reserve forming conditions of high evolution marine strata , including types of hydrocarbon source , the structural evolution , the condition of preservation and so on , it is considered that under the background of intensive structural movements , the " second " compensatory capabilities of the hydrocarbon source in the middle and lower yangtze region and regional preservation conditions would be the major factors to control the enriched oil and gas collection in this region 从分析高演化海相地层的烃源类型、构造演化以及整体封存等成藏条件，认为中、下扬子地区在强烈的构造运动背景下，烃源岩的“再次”补给能力和区域保存条件将成为控制中、下扬子地区油气富集的主要因素。
The yinachang fe - cu - ree deposit is one of typical deposits and mainly occurs in yinmin formation of kunyang group of middle proterozoic epoch . this paper mainly reports the results of investigation on the ree geochemistry of various rocks and minerals , the sources of ore - forming materials and the age of mineralization . the preliminary mechanism of sudden ree enrichment and mineralization in middle proterozoic has been interpreted 本论文选择迤纳厂矿床为主要研究对象，系统研究矿床不同类型岩(矿)石和矿物的稀土元素地球化学特征，探讨富稀土的成矿流体、成矿物质来源和稀土元素成矿时代，揭示昆阳裂谷初期因民组稀土元素富集的地球化学机制。
Cu - ni sulfided mine complex locate in baimazai of jinping county is sub alkali iron - super iron , it ' s zoning is clear and it ' s ni - cu - co melting first and enrichment , its rare earth is rich in right lean light rare earth , but eu in olive rock is serious to be bad , gd - tb is tittles negative abnormity . above - mentioned show that the mineral is cone from mantle , and didn " t mix with crustal substance , and continent tholeiite magma turning into continent tholeiite emplacement after by surging 金平白马寨铜镍硫化矿床杂岩体分带明显、属亚碱性铁质-超铁质岩、具ni - cu - co三元素先熔离，后富集的规律、稀土配分为右倾斜轻稀土富集型，但橄榄岩铕亏损显著， gd - tb微小负异常，显示成矿物质来源地幔，与地壳物质无混染和大陆拉斑玄武岩浆上涌后变为大洋拉斑玄武岩浆侵位特点。
Chemolithoautotrophic nitrifying bacteria have many unfavorable physiological characteristics , namely , slow growth , small biomass and susceptible to environmental factors . to remove high ammonia - nitrogen concentration in wastewater from refineries , we directly enriched nitrifying bacteria of activated sludge via optimizing enrichment conditions ( temperature > phu nh4 + - n concentration ) . the results showed that the number of nitrifying bacteria after 6 weeks enrichment increased 32 . 8 times and nitrification rate improved 2 . 76 times than that before enrichment 实验结果表明，在ph7 . 7 8 . 5 、 28 ， 150rpm振荡暗培养的条件下，通过不断添加富集培养基，经过6周的培养后，可以使硝化细菌的数量增加32 . 8倍，硝化速率提高2 . 76倍，达到了富集的目的。
The study covers regional geology , the physicochemical conditions of cu - ag polymetallic mineralization area , transport forms of copper and silver , the ore - forming geochemical mechanism of cu & ag , the geochemical characters of major element , trace element and lanthanon in mineralization field , the ore - forming age and geochemical mode , and so on 研究内容包括：区域地质和矿田地质，铜银多金属矿形成的物理化学条件，铜银迁移形式，铜银富集的地球化学机理，矿田常量元素、微量元素和稀土元素地球化学特征，白秧坪铜银多金属矿田成矿时代和地球化学模式等。
This process was propitious to enrich , activate , transport the copper . in different alteration granodiorite porphyry , sio2 , k2o , cu , mo are depleted in the fresh and weakly altered rock , and are enriched in the strongly altered rock , cl is also enriched in the strongly altered rock . but na2o and fe are extracted from the porphyry into the ore - forming fluid , especially the presence of fe is in favor of cu deposition 在铜厂岩体不同的蚀变带中， sio _ 2 、 k _ 2o 、 cu 、 mo等从新鲜斑岩甚至弱蚀变带中带出，而在强蚀变带强烈富集， cl同样有在强蚀变岩石中富集的趋势；而na _ 2o 、 fe从斑岩体中带出，进入流体相中，流体中大量fe的存在，有利于铜的沉淀、富集成矿。
