Diamonds were formed millions of years ago from carbon under extreme heat and pressure more than one hundred kilometers below the Earth's surface. They are found in volcanic "pipes" called kimberlite.

在数百万年之前，碳元素在地表面一百多千米之下的极度高温和压力下形成钻石，这些形成于地球深处的岩石由火山活动被带到地表或地球浅部，这种岩浆多以岩管状产出，因此俗称"管矿"。

To clarify this issue, we carried out a study to determine whether or not otoliths in the lagena of homing pigeons are richer in magnetic elements than those in the saccule and the utricle.

Two needle-shaped crystal chemicals were identificated from a plateau plant Halenia elliptica D. Don. Some analysis methods, such as EA, MS, NMR, FTIR and UV spectrometly, as well as melting point analysis, were used for the characterization of them, results showed that they were 1,3-dihydroxy-4,5,8-trimethoxyxanthone and 1-hydroxy-2,3,4,8-tetramethoxyxanthone.

Indexes of Cu, Pb-Zn deposits are contemporaneous fault, ore-bearing bed, volcanic rock with high potassium, volcanic structure, a serious of alternative in ore-bearing bed and under ore-bearing bed, high content of Pb, Zn, Ag, Cu, Cd, Ba, As, CaO, Fe, Mn, low Na〓O, Al〓O〓 in mineralizing body.

铅锌矿形成大矿富矿指标：①NW、NE向同生断裂；②有利含矿层位D〓k〓〓；③酸性富钾火山岩；④火山机构发育；⑤有利于矿质聚集的火山洼地；⑥发育与流体活动有关的矿下层、矿层、蚀变岩筒蚀变；⑦块状、浸染状铅锌黄铁磁黄铁矿石；⑧原生晕中Pb、Zn、Ag、Cd、Ba、Cu、As元素组合，CaO、TFe、Mn富集，Na〓O、Al〓O〓亏损，其下部位富K〓O或Na〓O。

It remains disputable that birds can obtain geomagnetic information for homing because otoliths in the lagena are rich in elements Fe and Zn.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但这个假说目前还存在争议。

The macula lagena is innervated and has neural projections to the brainstem, but its physiological function is still unclear. It remains disputable that it is because otoliths in the lagena are rich in elements Fe and Zn that birds can obtain geomagnetic information for homing.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但对于这个假说目前还存在争议。

The results show that the modificator Mg can cause thermodynamic undercooling , and it may absorb in the crystal faces of preferential growth of carbides, which can slow down carbides growing up on plate type and make them tend to be fine, isolated and passivated, and thus the impact toughness is improved greatly.

研究结果表明：在过共晶高铬白口铸铁结晶过程中，变质元素Mg不仅造成热力学过冷，而且Mg可能吸附于碳化物择优长大的晶面上，起到阻碍碳化物片状长大的作用，使碳化物趋于细小、孤立，且边部钝化，使冲击韧度显著提高。

The longer we remain in that place, fighting against the natural elements, the quicksand will turn from a soupy yet clingy mess to become concrete.

这样来想，我们卡住的地方好像我们在流沙里，我们呆那里越久，与自然元素抗争，流沙就会从沙状，到粘稠然后凝结。

The elements detected by EDAX revealed that the content of Cu, Fe and Cr in etched region was obviously greater than that in an unetched region where the Cu and Fe were segregated from the foils as the impurity and the Cr was induced from formed conversion coating.

采用SEM和EDAX技术，分析了铝箔在HCl、H〓SO〓、〓、HF混合液中恒流腐蚀后的表面形貌和元素分布，发现最初的蚀孔呈团簇状分布，而随着时间增加，蚀孔转变为均匀分布。

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。
