Gold occurs mainly in pyrite-sericite-quartz rocks and pyrite±polymetallic-sulphides+quartz±carbonate veins and stockworks, forming veinlet-disseminated ores.

金主要产于黄铁绢英岩和黄铁矿±多金属硫化物+石英±碳酸盐脉-细网脉中，构成细脉-浸染状矿石。

Numerous iron spherules have been found from coarse sandstone in the bottom of the Changzhougou Formation (1.8Ga) and silicified carbonate rock of the Dahongyu Formation (1.6Ga) of Proterozoic strata of the Ming Tombs District, Beijing.

北京十三陵中元古代常州沟组底部的粗砂岩(l.8Ga)和大红峪组硅化碳酸盐岩(1.6Ga)中都发现了众多铁质宇宙球粒。

Copper fixation rate affected by retention, fixation time, ligand type, and addictive. For all formulations, while other three conditions is the same, copper fixation rate of preservatives with low retention level is less than those with higher retention level; copper fixation rate of oven-dried bamboo samples is less than air-dried bamboo samples; copper fixation rate of amine-based preservatives is less than ammonia-based ones; copper fixation rate in some formulations containing carbonate and phosphate is higher than non-carbonate and non-phosphate ones.

在其它条件相同时，高吸药量时防腐剂的固着率明显高于低吸药量时的固着率；固着时间长的试样比固着时间短的试样具有更高的铜固着率；以氨水作配体的防腐剂固着性高于以乙醇胺作配体的；碳酸盐和磷酸盐在某些配方中能够改善防腐剂固着性。

For example, the porosity of sandstones tends to be facies related, whereas in carbonate rocks this is generally not so.

例如，砂岩孔隙度一般与相有关，而一般在碳酸盐岩中则一般并非如此。

It is common to find well-consolidated sandstones and carbonate rocks that remain gauge after being drilled.

通常对于固结良好的砂岩和碳酸盐岩来讲，其井眼比较规则。

For example, the porosity of sandstones tends to be facies related, whereas in carbonate rocks this is generally not so.

例如，砂岩孔隙度一般 SsbbwW.com 与相有关，而一般 SsbbwW.com 在碳酸盐岩中则并非如此。

The research efforts of seismites and seismic deposition, earthquake-tsunami sequence, vibrational liquefaction sequence in carbonate rock, seismites and seismic unconformity, sabkha seismites sequence, the autochthonous seismic liquefaction sequence in clastic rock were summarized.

对中国在海相和陆相地层的震积岩与震积作用、地震－海啸序列、碳酸盐岩振动液化地震序列、震积岩与震积不整合序列、萨布哈震积岩序列以及中生代陆相地层中碎屑岩原地系统的地震液化序列等方面的研究成果进行了综述。

So in this model the 3D distributions of the parameters of the reaction gases and resultants, that is temperature, velocity, concentration, and fuel cell current, voltage and power density can be simulated successfully.

通过与kW级的熔融碳酸盐燃料电池实验数据的比较，证实了本文的理论分析计算结果与实验结果的一致性。

P species, main as Ca-P and organic P forms, showing rego〓 pollution and karst area of lake watershed, inorganic P〓 related to Ca〓, Al〓, Fe〓 content in the overlying water, sediments is not a simple reservoir of dissolved phosphate and particle phosphate, near the interface, near 98% of total P existed as active forms, they may release to overlying water through reduction dissolution, deadsorption in the period of early diagenesis, only 2% of P as fixed forms, which mainly remained in the sediments, sediment was an important resource of nutrients of ovrelying water.

高原湖泊沉积物中的磷以有机磷和Ca-P形式存在为主，反映了高原湖泊流域污染和碳酸盐地区的整体背景，无机磷形式与水体吸附体Ca〓，Al〓和Fe〓的含量有关。底部沉积物不是溶解性磷酸盐和颗粒磷酸盐的长期储存场所，几乎有98%的磷是活性的形态存在，它们通过早期成岩作用在还原条件下还原，溶解和释放又重新回到上覆水体，只有2%的磷以固〓态的形式稳定保存于沉积物中，因此，沉积物为水体营养程度的重要来源。

Seepage activity is generally associated with the seafloor fractures and faults. Mud volcanes, pockmarks, hydrate, cold seep communities, and seep carbonate are common at the seep sites.

冷泉渗漏活动主要发育在海底裂隙和断层发育的地区，海底常有泥火山、麻坑、水合物、冷泉生物群落和冷泉碳酸盐岩的发育。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
