Everything from homogeneous pure chemicals to the most heterogeneous of minerals, overing the whole spectrum of the Mol hardness scale, except maybe diamond .

什么都可以，从纯的均匀化学物质到大多数非均匀的矿物，范围覆盖整个莫氏硬度，也许只有钻石除外。

I plant the production of high-purity quartz sand mining on their own quartz stone from the processing of raw materials, we have a unique purification technology and techniques, will quartz in potassium, sodium feldspar, mica and other metal ions from the exact chemical products Purity, physics, and optical properties of the 34 crystal-standard in the country is a unique product, and formed a large-scale production line the cause of 5,000 tons of annual output.

我厂生产的高纯石英砂是以自己开采的石英石为原料加工而成的，我们采用独特的提纯技术和工艺，将石英中的钾、钠长石，云母及其它金属离子分离确实产品的化学纯度、物理、光学性能达到三四级水晶石的标准，在国内属独一无二的产品，并形成了大规模的事业生产线年产量5000吨。

The on-line reaction kinetics of RIM polymerization of PU/VER SINs has been monitored by using a mini-RIM machine interfaced with FTIR During the course of synthesis, the two pairs of reactants interfere with each other in PU/VERA SIN system, although they follow different polymerization mechanisms and the possibility of inter-component chemical binding may be neglected (secondary hydroxyl groups of VERA capped).

在对机械搅拌混合物料PU／VER SIN体系进行了DSC、FTIR聚合反应动力学研究的基础上，本文首次利用第一台国产微型RIM机成功地实现了RIM PU/VER SIN体系合成时的FTIR在线聚合反应动力学测量。虽然PU、VERA网络的生成遵循不同的聚合反应机理（逐步缩聚反应、自由基共聚反应），并且两网络间的化学键合作用可以忽略（VERA为封闭仲羟基的VER），但合成PU/VERA SIN时两组份的相互作用不容忽视，两网络的生成速率均低于同样温度下纯网络的生成速率。

The pure and WO3-doped TiO2 nanoparticles photocatalyst was prepared by chemical precipitation, in which titanium tetrachloride was used as Ti-precursor, ammonia as precipitant and sodium tungstate as doping donor.

以TiCl4为钛前驱体，氨水为沉淀剂，钨酸钠为掺杂体给体，采用化学沉淀法，制备了纯的与WO3掺杂的TiO2纳米光催化剂。

A quirk of nature means that their island consists of some of the world's purest phosphate - the legacy of millions of years of sea bird droppings reacting with an uplifted coral.

在大自然巧妙的安排下，他们的岛屿遍地都是全世界最精纯的磷肥-是几百万年来海鸟的粪便与隆起的珊瑚起了化学作用所形成的。

Liquid glass is composed of almost pure silicon dioxide, the chemical constituent of quartz or silica, basically like ordinary glass.

液态玻璃几乎是由纯二氧化硅构成的，二氧化硅就是石英或硅石中的化学成分，基本上象普通玻璃一样。

A number of v=0~57 vibration levels were determined and assigned. The levels cover more than 99% of the potential well depth of the state. No evident autoionization was found related to the levels belonging to the 13 g- state above the ionization threshold, implying the distinct character of the doubly excited valence state from the Rydberg states.

并发现13 g-态能级即使超过电离限时亦无明显的自电离倾向，反映了双电子激发态不同于里德堡态的独特性质。13 g-态是碱金属双原子分子电离限以下唯一的3 g-对称性的态和电离限下唯一较纯的双电子激发态，这些结果为分子结构和量子化学的定量研究提供了重要的信息；（2）通过检测Na 3d 3p原子荧光，观察到Na2分子的33 g和43 g+态在3s+3d解离限以上的预解离能级及其转动线宽加宽等。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
