Electronic structure and optical properties of zinc blende CdSe have been investigated using the plane waves ultrasoft pseudopotential technique based on the density functional theory.

采用基于密度泛函理论框架下广义梯度近似平面波超软赝势法，计算了闪锌矿型CdSe的电子结构和光学性质。

In the present paper,ZnS:Ag nanoparticles were prepared with simple chemicals by hydrothermal method.XRD patterns indicated that the products have cubic zinc blende crystal structure.

以简单的化学试剂和实验过程，采用水热法制备出ZnS：Ag纳米发光材料。X射线衍射结果表明，产品均为结晶良好的ZnS立方闪锌矿结构。

A soft gray malleable metallic element that resembles tin but discolors on exposure to air; it is highly toxic and is used in rodent and insect poisons; occurs in zinc blende and some iron ores.

一种软且可延展的灰色金属元素，类似锡，但暴露于空气中会退色，有剧毒，用于制啮齿动物和昆虫毒药，见于闪锌矿和一些铁矿石中。

A further improvement of blister copper production technology is associated with production of white metal in autogenous smelting furnaces,continuous converting of high-grade copper mattes and generation of＜0.5% copper discard slage. copper concentrate ; autogenous smelting ; oxygen flame smelting ; Vanyukov smelting ; smelting in a stationary unit with top blowing ; smelting in a tilting furnace ; Russian ; CIS ; development

俄罗斯、哈萨克斯坦、乌兹别克斯坦均对自热熔炼工艺进行了改进，按照商业化的时间顺序分别为：氧焰熔炼、鼓泡熔池熔炼、固定式顶吹装置熔炼及类似于卧式转炉的可倾炉熔炼。1试验结果和探讨Ll权焰熔炼工艺氧焰熔炼工艺于1974年在乌兹别克斯坦阿尔马累克矿

Camellia oil can promote bone growth, promote the generation of mining agents and calcium absorption.

山茶油能促进骨骼生长，促进矿剂的生成和钙的吸收。

One day Boof, too tired to work any more, grasps one of the heavy wooden beams that support the roof shaft, bringing the mine in on top of the seven dogs.

有一天，Boof太疲倦以致於无法工作，它抓住支撑矿井屋顶其中之一沉重的木制梁柱，把矿带进来於7条狗的上方。

The main ore minerals are chalopyrite、bornite、chalopyrite、pyrite and nature silver, are mineral zoned from redbed to graybed appear chalcocite、bornite、 chalcopyrite and pyrite, chalcocite occur in front of ore bodies.

矿石矿物主要为辉铜矿、斑铜矿、黄铜矿、黄铁矿和自然银，很少见闪锌矿和方铅矿。矿物分带明显，从红层、辉铜矿、斑铜矿、黄铜矿、黄铁矿到浅色层，辉铜矿形成于矿体的前锋。

So he spent most of his time collecting mineral samples from the western boundary line of the new frontier.

所以他大部分时间都在新矿带的西边界采集矿物标本。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
