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。

Calcium montmorillonite was prepared by purifying LeXi bentonite with wet method two times. After purification, sodium modification of Ca-M was studied. A series of Fe/Cr-pillared montmorillonites were prepared with conventional method using sodium montmorillonite as experimental materials, and synthesis condition of Fe/Cr-PILM was studied and optimized. In order to shorten the preparation cycle of PILM by overleaping the step of sodium modification of Ca-M, the pretreatment technique for Ca-M has been pointed out for the first time. A series of PILMs were prepared with hydrothermal method using pretreated Ca-M as starting materials, which show that pretreatment of Ca-M is feasible.

然后，本文以莱西膨润土为原料，用二次湿法提纯了-2μm的钙基蒙脱石，对其进行了钠化改型研究；以改型后的钠基蒙脱石为原料，新型的铁、铬复合离子为柱化剂，研究并优化了常规离子交换法制备PILM的工艺；为了简化PILM的制备工艺，我们首次提出了蒙脱石的预处理工艺，希望通过预处理后可以省去蒙脱石的钠化工艺，以Ca-M为原料直接合成PILM。

The results of chemical analysis and X-ray powder diffraction showed that the borate is pinnoite .

确定该湖底硼酸盐是柱硼镁石（MgO·B2O3·3H2O），这是除硼土之外，最早在该湖区发现的第一个天然硼酸盐矿物。

The effects of the treatment show that the best effect is achieved by pillar ed acidified bentonite,whose COD removal efficiency is more than 80% and chroma removal efficiency is more than 95%.

处理效果最佳的是柱撑酸化膨润土，其对染料废水COD的去除率可达80%以上，色度去除率可达95%以上。

Its vining stems may be allowed to trail from a hanging container, or trained upwards on strings or a wire hoop, pushed into the soil.

可让它的藤枝从垂悬的盆上耷拉下来，或是用插入土中绳子或铁丝柱牵引直上。

The results show that the speed and adsorbability of alizarin red dye on four TiO2 pillared bentonites are much higher. The adsorption dynamics follows the laws of Bangham and Langmuir.

结果表明，4种TiO2柱撑膨润土吸附染料茜素红的速率和吸附量均较大，其吸附动力学行为均遵循Bangham方程和Lagmuir方程所描述的规律。

The results also show that integral moment is the main part of the foundation plate moments, the total deformation is like the pot bottom, and there is great moment at the root of frame column connecting with the foundation, which should be paid attention to in design.

分析研究还显示，由于考虑了地基土、基础与上部结构共同作用，在基础筏板的全部弯矩中，整体弯矩占主要部分。整体变形类似锅底状，以底部受拉为主要受力状态，同时与基础相接的框架柱根部有很大的弯矩，设计时要充分注意。

Pesticides were extracted from tea with hexane-acetone (volume ratio is 1:1) in an ultrasonic bath and cleaned up on a Florisil and neutral alumina column, then were determined by gas chromatography with negative chemical ionization mass spectrometric detection in the selected ion monitoring mode, and with heptachlor epoxide as the internal standard. Spiked blank samples were used as standards to counteract the matrix effect observed in the chromatographic determination.

茶叶试样用V/V=1/l混合提取剂超声提取，经Florisil矽藻土和中性氧化铝混合层析柱净化后，以环氧七氯为内标物，采用GC-NCI-MS的选择离子监测方式分析；探讨了茶叶试样的基体诱导色谱响应增强影响所产生的分析误差及其减小的措施，用空白试样基体匹配校准曲线法定量分析。
