Microstructure evolution in eutectoid steel during warm deformation in the temperature range from 600 to 700℃ was investigated by simulating hot compression test, SEM and thermomagnetic measurement. The effects of deformation and subsequent annealing on the spheroidizing of pearlite, refining of microstructure and dissolution of cementite were studied.

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

Methods Activate groups A and C meningococcal polysaccharide with cyanogens bromide and prepare into MenAPS-ADH and MenCPS-ADH derivatives by reacting with 1, 6-adipic acid dihydrazine. Mix MenAPS-ADH and MenCPS-ADH derivatives with purified tetanus toxoid at a certain mass ratio, then add l-ethyl-3(3-dimethylaminopropyl)-carbodiimide to prepare bulks of MenAPS-TT and MenCPS-TT conjugates respectively. Mix the two bulks at a certain ratio, add stabilizer and lyophilize to prepare group A+C meningococcal polysaccharide conjugate vaccine.

High-intensity combined safety glass is a revolution of glass plate history. Traditional glass is fragile, heavy and easy to hurt person when broken. However, high-strength compound safety glass consisted with two tempered glasses with a layer as a sandwich , its thickness is only 1.1 +1.1 mm, or 1.5 +1.5 mm, 1.8 +1.8 mm, 2.0 +2.0 mm—Intensity, as well as impact strength, of tempered glass have been greatly increased. Even if glass is broken, its splinter will be adhesive together and will not hurt person mainly coz the glass is very thin. This glass bears the duty of door hinge as door plate of wardrobe or cupboard in the installation.
