硅土

Field experiment was conducted to investigate the applying effect of biology silicon fertilizer to the soil fertility on serosity soil.

通过田间试验研究了在白浆土上施用生物硅肥的对土壤肥力的影响。

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。

By using cetyltrimethylammonium bromide as organic treatment agent, phenylmethylsilicone/organic montmorillonite nanocomposites were prepared by in-situ intercalative polymerization.

用十六烷基三甲基溴化铵做有机化处理剂，通过原位插层聚合法制备了甲基苯基硅树脂／有机蒙脱土纳米复合材料。

Results show that protons are liberated by dehydration or dehydroxylation after calcination at 500℃. These protons disrupt the silicon-oxygen-aluminium bridges where there are Al substitutions in the tetrahedral sheet of the montmorillonite. Some of silicon-oxygen and aluminum-oxygen tetrahedral invert to react with the pillaring agents and yield covalent bonds which firmly fix the pillars to the host clay. The Al-MMT are thermally and hydrothermally stable up to 700℃.

经过500℃高温焙烧后，交联剂经脱水或脱羟基释放出质子攻击蒙脱土四面体层中Si-O-Al四键，硅氧四面体和铝氧四面体发生翻转，与交联剂发生反应生成共价键，形成稳定的层柱黏土材料，在700℃高温下，Al-MMT材料不仅具有较好的热稳定性，而且具有较好的水热稳定性。

In addition the company also sell a variety of borides Agents, zirconia grinding ball, lithium-bentonite, silicon nitride iron, Castable superplasticizer used, brick,×, silica and other refractory materials and products .

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
