石灰

In this paper, the mechanism research of lime dry hydration was studied using small equipment. Then the effect tendencies of operational parameter of hydration process(water/solid) on lime slaking rate、 particle size and specific surface was put forward.

本文利用小型机理实验装置进行了石灰干式消化机理实验研究，得出了消化工艺操作参数对生石灰的转化率、消化产物的粒径和比表面积的影响趋势。

The mixers of both slaking and holding tank are provided withemergency power, to prevent the lime milk to settle down in thetanks.

熟化槽和贮槽的搅拌器都配备应急电源，以防止槽中石灰乳的沉淀。

Background: The main raw materials of lime sand bricks are tailings of silicon materials and calcium lime. They are standard bricks made through mixing, pressing and autoclaving. Their features include beautiful appearance, good quality and high solidness. An ideal substitute for clay bricks, they can be widely used in the base, the interior and exterior walls of constructions.

一、项目背景：灰砂砖是以硅质材料尾砂和钙质材料石灰为主要原料，经混和、压制、蒸压工艺制成的标砖，具有外观质量好、强度高等性能，可广泛应用于建筑物基层，底层及内、外墙体，是理想的实心粘土砖的替代产品。

Using the young leaves of Sorbus folgneri as explants to induce callus, the best medium was 1/2MS+ 0. 5mg/L 6-BA+0.1 mg/L NAA+ 0. 5mg/L 2, 4-D, and the inducement rate could be up to 90%.

用石灰花楸的幼嫩叶片为外植体材料诱导愈伤组织，最适培养基为1／2MS+0.5mg／L 6-BA+0.1 mg／L NAA+0.5mg／L 2，4-D，诱导启动率达90％以上。

Methods Eight cases of cerebral sparganosis treated at Huashan Hospital between 1982 and 1997 were analyzed retrospectively.

结果本病的病理特点为：1蚴虫虫体为实体，无体腔，具特征性体壁；2蚴虫虫体内散在分布的同心圆性圆形或椭圆形的石灰小体及单个肌纤维；3脑内有新旧不一的多发性小脓肿。

Rice was grown during the first 4 years, but after yield reduction of 2,520 kg/ha in the 2nd year to 1,500 kg/ha in the 4th year, the land was limed (3 t/ha) and green manured with Stizolobium aterrimum.

头4年种稻，但产量从第二年的2520公斤/公顷降为第四年的1500公斤/公顷后，就使用了石灰（3吨/公顷）和绿肥孟加拉黧豆。

Furthermore, lime interferes with the precipitation of struvite.

此外， 石灰干涉鸟粪石的降雨雪。

According to the data of chemical composition analysis, XRD and TGA, the rule of carbonate and sulphation reaction in middle temperature range is found, and the feasible temperature range is determined for SO〓 removal with the carbonate reaction occurring at the same time.

为了进一步发展中温烟气脱硫技术和蒸汽活化技术，今后还将研究床内的物料量和循环倍率对脱硫效率的影响，同时利用本文单纯石灰脱硫和蒸汽活化所得到的结果和机理，研究粉煤灰存在的情况下，蒸汽活化对脱硫剂钙利用率的影响。

After several repeated experiments on waste water sample, a three-stage neutralization treatment process was selected which used lime neutralization at first and then sulphurization.

葫芦岛有色金属集团有限公司冶炼烟气制酸中产生的酸性污水pH值在1以下，且含有大量的Zn、Cu、Pb、Cd、As、Hg等污染物，采用石灰中和加硫化处理的三级中和治理工艺。

Results show that paste containing ground limestone can be destroyed at the temperature of 0-10℃ by the sulphate attack of thaumasite form.

结果表明：掺石灰石粉的水泥石在0-10℃的温度范围内，可形成碳硫硅钙石的硫酸盐侵蚀破坏。
