The thermodynamic calculation of the optimum temperature range for the decomposition of calcium carbonate and the desulfurization by calcium oxide is presented in this paper.

The influence of the temperature span, temperature range, flow time and flow rate were investigated in the experiment.

The effect of temperature range for ultrasonic treatment on solidification structure of AZ91D and AZ31B magnesium alloy was investigated and the mechanism of refining solidification structure of magnesium alloy by power ultrasonic treatment was discussed.

First a nonlinear ARMAX model for the average load is constructed taking into account the historical load and the next day outdoor temperature,based on this nonlinear model,several time-varying linear sub-models are obtained for different temperature intervals and the parameters of sub-models are identified using an on-line recursive algorithm.

According to the special geological environment of army reclamation region,temperature interval and deformation stages division of soil mass of salt and frost heaving diseases in frozen saline soil area are analyzed.

In the molecular field approximation, the effects of molecular biaxiality of nematic liquid crystals on lowest supercooling temperature in isotropic phase and on the critical magnetic field are studied.
