In the practice of mineral process, the dotation of marmatite is one of the dii'l'iculL problems of polymetal sulphide separable flotation, which makes it difficult to increase the recovery of zinc mineral at the marmatite mine in wenshan ,which makes it even more difficult because of its ore characteristic.

选矿实践中，铁闪锌矿的浮选是目前多金属硫化矿分离的难题之一，文山铁闪锌矿的浮选回收率及品位由于矿石特性所致，要使其达到较好的指标，具有较大的难度。

The results show that the particles character as the growth of anion coordination tetrahedron during solvent thermal treatment, where blende-type ZnS particle is in the shape of double cone or tetrahedron, blend-type CdS appears as the tetrahedron, but wurtzite-type CdS is in the shape of cone. In addition, the particles with the better crystallinity are obtained with the increase of solvent thermal treatment temperature and time.

结果表明：采用溶剂热处理，粉末形状呈现负离子配位多面体生长特征，闪锌矿型ZnS粉末由球形变为双锥状或四面体状，颗粒上有明显的电子衍射花纹；闪锌矿型CdS晶体粉末主要呈四面体形状，而纤锌矿型CdS晶体粉末则以锥状为主，并且粉末的晶型随溶剂热处理温度的升高和时间的延长更趋于完整。

Not only for obtaining practical application but also to providing theoretical basis of ore drawing, a combined conceptive model of column drawing and MMVD has been resulted which is applied for the ore drawing simulation of high level block caving production management.

为了便于实际应用，又具有理论依据，提出了柱状体与改进的空位扩散模型的组合概念模型，该模型可应用于高阶段矿块崩落法放矿生产管理的放矿仿真中。

When it is crashed to -3 mm and is mixed uniformly it will become the sample for multi-elements analysis raw ore screening and elutriation raw ore mineralogy research and gravity concentration test.

试验矿样取自选矿生产现场，经破碎至-3毫米，均匀混样后作为本次试验的多元素分析样品、原矿筛分及水析样品、原矿矿物学研究样品和重选试验样品。

The static high-pressure experiments show that enstatite transforms to perovskiteSiO〓 at high pressure, so perovskiteSiO〓 is thought to be one of the main compositions of the lower mantle, but if it could keep the perovskite stucture in the whole lower mantle condition, there are still different opinions.

静高压实验研究表明，高压下顽火辉石将转变为钙钛矿型SiO〓，于是人们将钙钛矿型SiO〓列为下地幔的一种主要候选组分，但对于钙钛矿型SiO〓在下地幔压力(24-136GPa)和温度条件(约2000-5000K)是否保持单一相态的问题，目前尚存在不同意见。

Methods 1000 children first permanent molar normal eruptively were surveyed the extent of initial demineralization on the caries saitivity position by laser-fluorescence system KaVo DIAGNOdent,and chosen 60 no- demineralized children and 60 initial-demineralized or caries-susceptible children,Data were collected by questionnaire from their parents and analyzed by logistic regression and x2 test on computer.

采用激光荧光测定仪对1000名第一恒磨牙均已正常萌出的儿童进行龋敏感点位脱矿程度检查，随机抽取釉质无脱矿组和釉质脱矿组或龋病损组，60份有效配对问卷，进行x2检验及Logistic回归分析。

Electricity character test results showed that it was chemical adsoption between hydroxamate and Perovskite surface, because the floatability of Perovskite is good when the ε-potential value of Perovskite was negative number all along in the range of test.

矿物表面电性研究表明，钙钛矿在研究的范围内ξ电位始终为负值，而钙钛矿在C〓羟肟酸作用下可浮性很好，表明C〓羟肟酸在钙钛矿表面发生了化学吸附。

Its displayed 98% silver mineral of FengNing silver mine distributes in galenite and sphalerite and associate with galenite and sphalerite close., 1% silver mineral distributes in gangue.

研究表明：丰宁银矿的铅锌矿中银矿物有98%分布于方铅矿和闪锌矿中，并与方铅矿和闪锌矿紧密共生，有1%左右的银矿物分布于脉石矿物中。
