在F〓体系中，F〓对铝源和硅源起络合和矿化作用，形成可溶性氟硅酸盐AlF〓〓、SiF〓〓络合物，然后缓慢水解成含氧氟硅酸盐络合物，它们再发生定向缩聚，提供了分子筛晶体生长所需的可溶性结构单元。

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

The results showed when the mass fraction of DBDPO/Sb2O3 composite flame retardant was 8%,the flame retardacy of the system came up to UL94 V0;when the adding amounts of tougheners were the same,the toughening effects of tougheners were as follows:POE-MAH PET/montmorillonite ; Flame Retardation ; Glass Fiber Reinforcement ; Toughener ; Compounding ; Mechanical Properties

中国纺织科学院采用插层聚合法制备了PET/层状硅酸盐纳米工程塑料，并获国家专利[1]。利用PET/蒙脱土层状硅酸盐为基体树脂，通过添加玻纤、阻燃剂、增韧剂制备可在低模温下成型的PET/蒙脱土玻纤增强阻燃工程塑料，解

The results show that the dispersity order of phosphates from strong to weak is as follows: sodium hexametaphosphate, sodium pyrophosphate, trisodium phosphate.

结果表明：磷酸盐对这4种矿物分散效果由强至弱的顺序为：六偏磷酸钠，焦磷酸钠，磷酸三钠；六偏磷酸钠增大铝硅酸盐矿物颗粒表面电位的绝对值，从而提高了颗粒间静电排斥作用；同时，六偏磷酸钠吸附于铝硅酸盐矿物表面后，加剧了颗粒之间的空间位阻效应，使颗粒间产生较强的位阻排斥力。

The grindability of cement clinker was better than ordinary Portland cement, for example, on the same condition it took the high alite content Portland cement clinker 4.5min to grind to a specific surface area of 320m2/kg, while the o...

同时这种水泥熟料的易磨性优于普通硅酸盐水泥熟料：在相同条件下，磨细到比表面积320m2/kg时，这种熟料需要4.5min，而普通硅酸盐水泥熟料则需要8.0min。同时对该熟料进行了岩相检验分析。

As the cement includes sulphoaluminate clinker,it will an make important effect to the hydration and hardening of Portland cement when adding sulphoaluminate in clinker,such as accelerating the hydration rate of alite and belite clinker,improving the degree of hydration and the quantity of hydrates,and advancing early strength.

阿利特-硫铝酸盐水泥是一种早强性能优良的新型材料，由于在水泥熟料矿物体系中含有硫铝酸盐矿物，将对以阿利特为主导矿物的硅酸盐水泥的水化硬化产生重要影响：加速硅酸盐熟料水化，加快水化进程，促进水化产物生成量，提高早期强度。
