Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.

说明早期成矿流体为富含CO〓、H〓O等的碱性流体，其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源，带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化，带出的Na〓则在浅部形成钠长石脉。

The main ore_stage alterations related to hydrothermal fluids include ①early K_silicate alteration,②silicification,③ pyrite_sericite_quartz alteration and ④propylitization.

成矿期间与矿化热液活动有关的蚀变主要有：①早期钾硅酸盐化；②红柱石次生石英岩化；③黄铁绢英岩化；④青磐岩化。

The main ingredient of quartz is Silicon Dioxide,it is a special purpose industrial material.

石英玻璃在紫外到红外的整个光谱波段都有较好的透光性能，可见光透过率在93%以上，特别是在紫外光谱区，最大透过率可达80%以上。5、电绝缘性能好。

Background: The interaction between macrophages and SiO2 is generally believed to play an important role in silicosis formation.

背景：矽肺的发病机制中，一般认为肺巨噬细胞与石英(SiO2)相互作用而产生的诸多因子在矽肺发生发展过程中起到关键性作用。

The relationship of the changes in chest radiograph and silicotic pathology to the content of lung quartz, and the biochemical indices was studied.

结果说明肺石英量的多少直接影响了矽肺病变和肺部X线改变的程度。

Different content of lung quartz had a direct effect on lung silicotic pathology and the X-ray manifestation of chest, and caused the difference of collagen fibrosis in lung tissue and that in the content of serum ceruloplasmin in individ...

肺石英量的差别导致了个体间肺组织纤维化程度的差异，从而表现为个体间血清铜蓝蛋白含量的差异。研究结果提示，血清铜蓝蛋白含量可作为衡量矽肺病理改变的良好指标之一。

With the decreasing temperature, the solubility of the other components in sillimanite decreased and most of the dissolved components were exsolved, resulting in the formation of the exsolution texture.

南极拉斯曼丘陵长英质片麻岩中的粗粒夕线石可能有内部出溶现象，出溶形成的矿物有磁铁矿、钛铁矿-赤铁矿和石英出溶矿物条纹，并有少量的斜方辉石。

Field structure, microstructures and quartz C-axis analysis all indicate sinistral shear sense of the ductile shear belt.

野外构造、显微构造与石英C轴组构分析皆指示为左旋走滑韧性剪切带。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
