Effects of Ti/Al Ratio on Microstructure and Tensile Strength of Cast TiAl Alloys;

This paper makes an initial study on the in fluences of the reactent s concentrationdensity and different calcinating temperatures on Ti/Ba mole ratio in the resulted BaTiO_3.

Analysis on the mole ratio control of the feed material components in oxychlorination reactor;

A mole ratio control system based on signal chip computer;

This paper described the influence which the mole ratio of MgO/MgCl2 and an additive which is silicon powder effect on the strength of the magnesia's abrasive products.

It shows from experimentS that Sold leaching depends not only upon superfine ore-grinding but also upon alkali pretreatment in order to change the matrix of sulfide ore and enable the mol ratio between total cyanide and copper in the pulp higher than 3:1.

Influence of weight ratio of three modifying agents to rubber powder,mol ratio of modifying agent A to phenol,mol ratio of modifying agent(A+ phenol) to formaldehyde,acidity and alkalinity of reaction system,reaction temperature and time on fluidity and fluidity retaining of the SRP/mortar was investigated.
