The glazed roof tile with single firing reached the national standard GB9197-88 and industry standard of building materials JC/T765-2006.

A raw glaze has been successfully studied for bone china using in single firing,in the condition that has not lowered the prensentation quality and internal property of the product,lowered the cost.

The batches for glazed maiolica articles of single firing were synthesisel with lacal claies,the formation of bodies and glazes was discussed,and the time-temperature parameters were defined.

Application of smooth blasting one-step forming technology in drift driving for large-sized section;

Because the best scheme of the rock mining is adopted, namely the construction technique of digging rock as filling-stuff for embankment is with one-step forming to fit the criterion of filling embankment; not only much existent problem were resolved during construction, and satisfied construction demands, but also the construction period was shortened; and the.

During the smelting process for V-Ti containing molten iron,we can increase the convertor life by improve the walling up technology,using the one-go operation,decreasing the tapping temperature,restructurding the slag system and improving the effectivensee of slag-splashing for protecting of converter and so on.
