The PGE distributive patterns are the PtPd type, the Pt/Pd ratios of 0.32-0.68 are between the values of enriched sulfide tholeiite (0.38) and primitive upper mantle (1.36), and the similarity of partition patterns of chondritenormalized REE, MORB-normalized trace element and primitive mantle normalized PGE for the rocks of the three phase zones, indicate the Baimazhai intrusive body I formed by the evolution, liquation, intrusion and diagenesismetallogenesis of basaltic magma.

铂族元素配分模式为Pt-Pd型，w/w比值为0.32~0.68，介于富硫化物拉斑玄武岩(0.38)和原始上地幔(1.36)之间，以及稀土元素配分模式、微量元素蛛网图和铂族元素配分模式中不同岩石配分曲线的相似性揭示3个相带不同岩石之间的高度一致性，展示基性-超基性岩形成于玄武质岩浆演化、熔离及岩浆一次性侵入、分异成岩成矿的特征。

The sample was isolated by sephadex G-25 gel filtration column after concentration. Then bioactivity was assayed by Candida albicans. The chemical components were isolated and identified by GC-MS. GC determined the relative percentage content of the extract, nine kinds of components were separated, identified and accounted for about 82.12%, the major compound was propenyl methyl disulfide.

浓缩后的样品通过Sephadex G-25凝胶柱分离提纯其中的有效成分，以白色念球菌进行生物活性测定，并用气相色谱-质谱法对其化学成分进行分离鉴定，GC法测定各种化合物的相对百分含量，共鉴定了9种成分，约占总提取物的82.12％，其中，主要物质是甲基丙烯基二硫化物。

Because jiao lu is gas medium contain the impurity such as tar, naphthalene, ammonia, sulfide and prussiate, existence is taken pressure mouth and bring pressure pipeline is easy jam, metric not accurate, online sweep the problem such as difficulty.

Silver has two forms in its occurrence:mainly in the form of silver-bear iug sulfosalts(pyrargyrite,freibergite and Ag,Zn-bearing tetrahedrite and others) discovered for the first time;secondary,in the form of impurities scattered in the memllic sulfides.

银主要以首次发现的含银硫盐矿物（深红银矿、银黝铜矿和含银锌黝铜矿等）产出，其次是杂质元素分散在金属硫化物中，银的含量按方铅矿、黄铜矿、闪锌矿、黄铁矿的顺序依次降低。

The content of heterocyclic compounds in meat flavoring was more than other compounds. There were twenty-three sulfides in forty heterocyclic compounds. The pH 5 meat flavoring had fewer flavor compounds. In all pH samples, when pH was increasing, pyrazine content was increasing too.

在40种的杂环类化合物中有23种为含硫化物。pH 5的部份产生的风味化合物较少。pH 5~9中，pyrazine的含量有随著pH的上升而逐渐增加的趋势。
