The flame-retardant/smoke-suppressant of PVC may be divided into three kinds. The first is FRs , includes the compounds lying in IVB～VIB, such as TiO〓, V〓O〓, Cr〓O〓 and MoO〓; The second is FRs , includes the compounds lying in VⅡB～IB, such as MnO〓, Fe〓O〓, Co〓O〓, CuO and ZnO. The third is FRs , includes the compounds of subgroup A, for example Mg 〓, Al 〓, Sb〓O〓, carbonate and phosphate.

PVC的阻燃抑烟剂可分为三大类，第一类阻燃抑烟剂为元素周期表中IVB～VIB族的化合物，以TiO〓，V〓O〓，Cr〓O〓和MoO〓为代表，第二类阻燃抑烟剂为元素周期表中VⅡB～ⅡB族的化合物，以MnO〓，Fe〓O〓，Co〓O〓，CuO和ZnO为代表，第三类阻燃抑烟剂为三氧化二锑，氢氧化镁，氢氧化铝等主族元素的化合物。

For example, the set algebra for the set T defined above corresponds to a Boolean algebra of 32 elements.

例如，上文定义的集合的个元素集合代数就对应一个有32个元素的布尔代数个元素的布尔代数。

This trail consisted of four parts as follows:1、Study on basicphysio-chemical properties of oxytetracycline complexes and their relative properties in VitroIntestinal Juice;2、Effect of mineral elements on the inhibitory efficiency of oxytetracycline

试验分四部分：1金属元素土霉素络合物的基本理化性质与其在体外消化液中相关性质的研究；2矿物元素对土霉素抑菌效果的影响；3在不同的给药下方式研究矿物元素对土霉素吸收的影响；4矿物元素对土霉素促生长性能的影响。

For each element in orig, we push a copy of value in that element onto this Queue and advance pt to point to the next element in orig.

对于 orig 中的每个元素，将该元素值的副本 push 到这个 Queue，并推进 pt 以指向 orig 中的下一元素。

The bamboo charcoal contained abundant mineral substance and microelements such as Cu, Se, Zn, Sr which are benefit to people, further more, the content of harmful metal elements is very low.

不同最终炭化温度竹炭中的碳元素的含量随着炭化温度升高而升高，而氢、氧元素含量则相反；竹炭含有丰富的矿物质和人体必须的微量元素如铜、硒、锌、锶等，而对人体有害的重金属元素含量很低或在安全范围之内。

Element geochemical study shows that the contents of Zn, Pb, and Cd in the regional strata and host rocks are typically higher than those of similar lithologies of the earths crust.

元素地球化学研究表明，区域地层和容矿岩石中主成矿元素Zn和Pb及分散元素Cd的含量普遍高于地壳同类岩石丰度，其中Zn和Cd的含量通常高出十倍以上。

Re is moderately incompatible element, while Os is highly compatible. As they are highly siderophile, ReOs isotopic system can provide unique insight in dating and tracing research compared to other longlived radiogenic isotope systems (e.g. RbSr, SmNd, UThPb ) which involve lithophile elements partitioning into silicate rather than metal or sulfide.

Re为中等不相容元素，Os则属强相容元素，与母子体均为不相容元素的RbSr、SmNd、UThPb等同位素体系相比，具亲铁、亲硫性的ReOs同位素体系在定年和示踪研究中显示出特殊性，受到了地学家高度重视，其应用正走向普及。

These versions operate positionally: We specify a starting position, and in some cases a count, to specify the element or range of elements which we want to manipulate.

这些版本只能通过位置操纵元素：指定起始位置，在某些情况下还需指定一个计数器，由此指定要操纵的某个元素或一段元素。

The content of the element may not have been correctly supplied by the reader, e.g. as in the cases of corr and abbrev elements.

标记者所提供的元素内容也许有误，例如在元素corr和元素abbrev出现的情况。

The Haber process provided a new supply of "fixed" nitrogen to make fertilizers that are now responsible for sustaining one-third of the world's population.

哈勃过程开始于氮元素的一种非固定状态（氮气，这种状态下的氮元素是不容易被利用的），或者其他形式的包含氮元素的气体如氮氧化物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
