The source of Fe was provided strong supporting evidence. Iron isotopic ration of BIF has the positive dependence ofδEu, indicating the source of Fe correlation with hydrothermal fluid.9. A model for Fe cycling.

首次从成矿元素本身为BIF的物质来源提供直接证据：BIF的Fe同位素成分与Eu异常存在非常明显地正相关关系，这清楚地表明鞍本地区BIF中铁的来源与海底火山热液活动有关。9。

In the contaminated lard sample, 6 organic compounds have been thus identified to be the raw materials or byproducts in the production of organic tin compounds. Based on the identified contaminants, it can be postulated that the chemical structure of the organic tin compound is dibutyltin-bis-(2-isooctyl thioacetate). The method is simple and precise, and has not been reported in the local literature.Keywords Organic tin compound, Lard, SPME－GC－MS

经过摸索研究，采用固相微萃取方法富集挥发性杂质，直接注入色谱中，经色谱分离，质谱测定，确定了杂质的结构，由杂质成分推断生产有机锡所用的原料，然后判断合成路线，最后确定有机锡的结构，从有毒猪油中鉴定出2－巯基醋酸异辛酯、双（2－醋酸异辛酯）二硫、双醋酸异辛酯硫醚等6种与有机锡有关的杂质，并与相应的有机锡工业品对照，发现工业品中也含有这些杂质，与其合成过程的原料及副产物相符，从而确定有机锡化合物为二硫代醋酸异辛酯二丁基锡。

Throats are so easily blocked up for clay in rocks that the permeability decreases and the output is affected. The problem can be mostly worked out by inputting clay inhibitor into formations. Production well loggings, such as well logging of output profile, well logging of injection profile with five parameters, engineering well logging, were gained research in Hailaer oil field in this paper.

海拉尔油田是低渗透且具有断块性质的新开发油田，本文提出在对海拉尔油田开发进行地球物理监测时需要解决一系列关联的钻井地质工程问题，诸如岩石中富含粘土成分容易引起地层微粒堵塞喉道、孔道，从而导致渗透率下降现象，直接影响采油井产量。

It used the help of a Swedish production of gold, Germany advanced forging process, selected high toughness and hardness of the high-alloy materials, the bionic magnetized, low-temperature gold-plated, antimicrobial technology, such as the United States to import equipment plastic micro-needle, the application of advanced beauty High technology and breakthroughs in genetic engineering of the characteristics of active ingredients, use of plastic micro-needle the United States, used "to the point of" infiltration of AMD technology, multi-point, uniform, comprehensive, in-depth the high-energy original fluid, directly transported to the Skin, containing a variety of nutrition and active components of high-energy original fluid, rapidly absorbed by the skin organizations, play a role, resulting in effect, promoting skin metabolism, and maintain skin elasticity and Jiaomei.

Most skin whiteners currently on the market contain ingredients hydroquinone, ascorbic acid, kojic acid, arbutin, azealic acid, glycyrrhetinic acid (licorice extract that act as direct inhibitors of tyrosinase, the enzyme in the skin pigment cells that make melanin.

目前市场上大多数皮肤漂白剂含有成分（氢醌，抗坏血酸，曲酸，熊果苷，azealic酸，甘草次酸），即作为直接的酪氨酸酶抑制剂，在皮肤色素细胞，使酶黑色素。

In this paper, we present the idea of virtual plate for aspheric testing based on moire phase-shifting technology, i.e. when testing steep aspheric wavefronts, interferometry directly used CCD camera for high resolution to obtain supervision with interferometry saved in the frame memory produces moire patterns. Finally, we cancel the noise by means of low pass frequency .

在检测非球面波前时，我们改变以往传统的零位补偿检验手段，而利用高分辨率的CCD相机直接对被检非球面进行数据采样，并把获得的干涉条纹和预先储存在储存器里的参考干涉图进行叠加，从而得到电子莫尔条纹，然后对获得的电子莫尔条纹进行低通滤波，滤掉噪声中含有的高频成分，以提高图像的信噪比。
