The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

Twelve kinds of volatile products in the fermentation broth were determined, in which ethanol, acetic acid, 1, 2-ethanediol, butanoic acid and glycerine were the major compounds, and they can be utilized by methanogenic organism directly or be changed into compounds that can be utilized by methanogens organism directly.

MC1分解木薯渣过程中可溶性物质总含量开始为18%，3 d后达到最高，为33%，GC-MS测定挥发性产物的总量在培养6 d后达到最高，挥发性产物共检测出12种，其中量较大的化合物为乙醇、乙酸、乙二醇、丁酸及甘油，这些产物为甲烷发酵菌可直接利用或者容易转化为甲烷菌直接利用的成分。

First, the court interpreted the Clean Air Act permissively: the EPA's mandate to regulate emissions that "will endanger" public health was satisfied if the agency showed a significant risk of harm, not necessarily proof of actual harm.

首先，法院很宽容地解释了《空气洁净法》：如果环境保护署可证明存在很大的"将危害"公众健康的危险，其调整铅添加剂的挥发的命令即符合有关要求，而不必证明实际上的危害。

The AVS-SEM distribution in the sediments of Guanting Reservoir and Yongding River was studied and the metal concentration in the water above the sediments and the pore water was measured. Based on the results, the reaction between the sediments and metal ions were discussed and the heavy metal pollution of the sediments in Guanting Reservoir and Yongding River was evaluated preliminarily.

官厅水库沉积物，由于处于缺氧性环境，沉积物中的酸可挥发性硫化物控制着大多数金属离子在沉积物和孔隙水两相间的分配，本文通过现场采样，分析了官厅水库和永定河沉积物中的AVS—SEM的分布，同时测定了沉积物上覆水以及部分样点的孔隙水中的重金属浓度，探讨了沉积物与重金属离子的作用；并根据采样分析结果对官厅水库及永定河沉积物中的重金属污染做了初步评价。

The whole column is placed in a thermostatically controlled heating jacket. A volatile sample is introduced into the column using a syringe, and an unreactive carrier gas, such as nitrogen, passed through it. The components of the sample will be carried along in this mobile phase. However, some of the components will cling more readily to the stationary phase than others, either because they become attached to the solid surface or because they dissolve in the liquid.

将整根柱子固定在一个可控制的恒温热罩内，用注射器把易挥发的待分析样品加入到柱子中，再令反应惰性的气体载体通过柱子，例如氮气，此时样品的各成份就会在流动相中移动，然而其中某些成份更倾向依附于固定相，可能的原因是它们能够依附于固体表面或是溶解于固体表面的液体中。

In view of different volatile substance in beer, PEG column and FID （hydrogen flame ionization detector） were selected in the measurement. Besides, quantitation analysis of involatile compositions in beer could be done by internal standard method or by external standard method.

针对啤酒酒中不同的挥发性物质可选择PEG柱和氢火焰离子化检测器法进行检测；还可用内标法和外标法对啤酒中的不挥发组分进行定量检测分析。
