混凝土小型空心砌块具有节土、节能等一系列优点，是一种绿色的墙体材料，具有广阔的发展前景。

In order to stabilize and recycle municipal solid waste incineration fly ashes,chemicaltabilization with copperas as agent was firstly applied and then the treated fly ash was solidified by mixing with cement,the resulted concrete blocks are save and strong enough to be used in some special cases.

为实现垃圾焚烧飞灰的无害化和资源化，先将绿矾溶液与飞灰混合后氧化稳定飞灰中的重金属，然后将处理后的飞灰与水泥混合、养护，使焚烧飞灰在双重稳定化的同时，得到的水泥砌块浸出浓度低，具有相当的强度，可以在特殊场合安全利用。

"Tile:Thin, flat slab or block used structurally or decoratively in building."

瓦：薄而扁平的板或砌块，用作建筑的结构材料或装饰材料。

Hydrolysis of 2,3-epoxy-butanol-p-methylbenzensulfonate (12) in acidic aqueous media gave chiral vicinal diol (2) in high enantioselectivity (95% ee).2. The chiral vicinal diol s play an important role in organic .

手性邻二醇在有机合成中具有重要的用途，它们是理想的手性合成砌块，可用于合成多种手性药物，许多含有手性邻二醇结构的药物或生物活性物质将有更重要的应用。

So to synthesis the key chiral building blocks for these single enantiomer chemical products has become one of the most important and hot fields in organic synthesis.

因而合成这些手性产品的关键手性砌块也成了当前合成界研究的热点。

In this paper it is dealt with the field investigation, theory analysis and experimental study for CSCBB.

本文在该课题中承担砌块墙体试验研究以及理论分析和调查研究等部分的内容。

Production of fire clay declined by 19.5% to 383,000 t valued at $5.97 million, with 88,200 t used in heavy clay products and lightweight aggregates (-12.7% compared to 2000) and 277,000 t used in firebrick, block, shapes and other refractories (-20.4%).

耐火粘土产量也下降至38.3万吨，比2000年下降了19.5%，产值约597万美元。其中有88200吨用于重粘土产品和轻质骨料生产（下降了12.7%），27.7万吨用于耐火砖，砌块，异形砖和其他耐火材料，下降20.4%。

The experimental study is made on low strength of the autoclaved aerated concrete block s using fly ash of gangue power plant.
