挥发的

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。

It is discovered that the ignition temperature T1 of the mixtrues to be used to produce briquets is reduced and the successive combustion temperature T2 of the mixtures is increased owing to mixing some inorganic matter with raw coal. The...

据此，试图说明如下现象：在同样的层燃炉中，当原煤挥发分高时，型煤比原煤烧得更好；当原煤挥发分较低，而无机添加物又过多时，型煤不如原煤烧得好，出现接火困难、炉渣中可燃物过高等现象。

Ammonia volatilization in relation to N application rate and climate factors was studies through field experiment in red soil under the crop rotation of Smooth Crabgrass in spring and Winter Radish in autumn Results indicate that ammonia volatilization in Treatments N90, N160 and N230 in spring dragged on for 10~17 days, and peaked at the 6th~8th day after urea application, reaching N0.11, 0.57 and 1.84kg hm^(-2)d^(-1), respectively, and the total amount of N loss through ammonia volatilization was N0.67~5.16kg hm^(-2) accounting for 0.74%~2.24% of the total N applied.
