This paper, aiming at the weak points of the low early strength and the slow setting and hardening of portland fly-ash cement , according to the forming mechanism of cement clinker minerals, cement clinker minerals are choosen, fly ash is used as a substitute of clay as raw materials, early and high strength type cement clinker has heen developed, the amount of alit in the clinker is very high.

本文针对粉煤灰水泥早强低，凝结硬化慢等缺点，根据水泥熟料矿物的形成机理，用粉煤灰代替粘土作原料，对熟料矿物进行优化组合，成功地研制出了一种高硅酸三钙的早期强度高的水泥熟料，这种熟料可掺入30％一40％粉煤灰，生产出425R型粉煤灰水泥。

The sol's sensitivity towater can be improved by using inorganic salts instead of alkoxide as bismuthand strontium precursors, and hence the sol-gel processing can be simplified.

用无机盐代替醇盐作为锶和铋的前驱体，可克服溶胶对空气中水分的敏感性，从而大大简化了SBT薄膜的制备工艺。

Domestic products raw material, which bastnasite was used as active component for DeSOx additives, were selected to use for the first time, the bastnasite can replace industrial cerium nitrate, it may improve DeSOx activity and abrasive resistance, due to admission bastnasite, but also reduce cost of material of DeSOx additives.

本文采用三种方法拟在活性组分的选择、活性评价及作用机理等方面对DeSOx添加剂强度进行有益的探索；尤其首次选用国产原料——氟碳铈矿作为镁铝尖晶石DeSOx添加剂的活性载体，使得氟炭铈矿可以代替工业硝酸铈，它既可提高脱硫添加剂的活性和耐磨强度，还可以降低原料成本。

A new predischarge trigger generator, that is more simple and stable than the former one, has been designed and fabricated using the car ignition loop DQ128. A Rogowski coil, that instead of the former device can much more accurately measures the current flowing through capillary, has been made and calibrated.

自制了罗可夫斯基线圈，并对其进行了标定，代替原先使用的回流器测量放电电流，解决了无法准确测量流过毛细管电流的问题，为实验分析提供了更准确的依据。

The average epoxy value and the average viscosity of such diluent were 0.502×10-2eq/g and 3.2 mPa.s(25 ℃) respectively. It was an ideal diluent and could be used instead of active diluent such as butyl epihydrin etc. and non-active diluent such as dibutyl phthalate etc. in epoxy resin industry. The preparation of the epoxy diluent by fusel oil could not only settle the problem of environmental pollution caused by fusel oil drainage, but also produce economic and social benefits.

结果表明，杂醇油制备的环氧树脂活性稀释剂环氧值平均为0.502×10-2eq/g，环氧值适中；粘度平均值为3.2 mPa.s(25 ℃)，粘度较小，为比较理想的环氧树脂活性稀释剂；该环氧树脂活性稀释剂可望代替环氧丙烷丁基醚等活性稀释剂和邻苯二甲酸二丁酯等非活性稀释剂应用于环氧树脂工业；可解决酿酒企业和酒精厂下脚料杂醇油排放带来的环境污染问题。
