The experimental results show that species distribution and the transformati on of PASC are different from those of PAC,owing to the interaction between poly silicic acid and hydrolyzed aluminum species.

实际结果表明，在PASC中，由于聚硅酸与铝水解聚合产物间的相互作用，使得铝的水解聚合形态分布及转化情况发生了变化。

Hydrolysis of silane inside of body tissues may produce silicic acid.

硅烷在体内水解可能产生硅酸。

The chemical characteristics were obtained when silicic acid existed in the iron hydrolyzed solution.

实验结果表明：硅酸的存在使Fe水解溶液的pH弛豫特征产生了一定的改变，表现出低OH/Fe摩尔比时的阻聚效应和高OH/Fe摩尔比时初期的促聚效应，并使Fe在溶液中的形态分布及转化特征发生了一定的改变。

The dissolution remarkedly slows down when the dissolved percentage of Ti is in excess of 22% due to lower reactivity of the perovskite and the coverage from silicic acid, of which the former may be the primary reason.

当钛的浸出率超过22%以后，浸出速度显著下降，这是钙钛矿的反应活性差以及硅酸的包裹所致，而钙钛矿的反应活性差可能是浸出速度显著下降的主要原因。

DTA-TG and IR analyses showed that the silicic acid gel structure converted gradually to the SiO〓 network during the heat-treatment process.

DTA—TG和红外光谱分析表明，硅酸的凝胶结构在受热过程中逐步转化为三维网络结构。

The weight crude material quality standard is 3 rate values: Lime saturation coefficient KH, silicic acid rate n, iron rate p.

衡量生料质量的标准是3个率值：石灰饱和系数KH、硅酸率n、铁率p。

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。

For higher temperature melts, sillimanite or alumina-silicate is used as a refractory, and silica is used as a binder.

对较高熔化温度而言，则采用硅线石或氧化铝硅酸盐作耐温材料，无水硅酸作粘合剂。

It puts forward the plan to use open hearth furnace slag in portland cement as the hydraulical admixture.

分析了钢渣的组成，介绍了钢渣利用的可能途径，提出了用平炉钢渣作为普通硅酸盐水泥水硬性混合材综合利用的方案。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
