The dynamic viscosity of pure liquid iron, which was calculated from Iida formula, and the surface tension, which was obtained according to Reynolds formula, are 6.44 mPa·s and 2.04 N/m at 1 550℃, respectively.

Approximate equations of motion of the liquid and the solid particles are obtained, and these are analogous to the Boussinesq approximation in the case of natural convection in a pure liquid.

The authors consider processes of reflection of waves from obstacles and their passage from a gas into a bubble liquid, from a two-phase mixture into a pure liquid.

It is known from experiments [1, 2] that after depressurization a rarefaction wave travels into the channel with the speed of sound in the pure liquid.

This theory allows the width of the hydrophobic layer to be calculated for molecules of arbitrary geometry by explicitly taking into account the water structure through the correlation function of a pure liquid.

Analysis of the experimental results indicates a gradual crossover from pure liquid-state (diffusion) to quasi-solid-state (rigid lattice) spin relaxation.

On the basis of analysis of the experimental data and their relationships, several new equation groups are presented, from which we can select the most accurate and reliable group to derive the PVT properties of pure liquid mercury, which may be used as the present standard data for the researches in precise measurement and thermodynamics.In the first part of the paper dealing with the density of mercury at 1 atm and a fixed reference temperature, we suggest a formula for correlating the density with its isotopic...

The residual deviations of the fitting equation are less than±5.5×10-7, it may also be extrapolated to -30℃ and 350℃.In the third part, we use the theorem of linear secant bulk modulus to derive the PVT properties and density table of mercury in the range of 0-1.3GPa and 0-150℃ The maximal uncertainty is±0.02% and will decrease with decreasing pressure.

A micro-pulsed pyrolysis chroma tograph has been developed for individual liquid hydrocarbon and mixed hydrocarbons. Reaction products distribution of pulsed pyrolysis primary reaction of individual hydrocarbon was investigated with this system, kinetics data of n-hexance pyrolysis were determined for pulsed reaction. Pyrolysis performance of Daqing light diesel was studied with a micro-pulsed reactor and a continuous tubular reactor. Consistency of data from pulsed pyrolysis and model reactor of industrial cracking furnace with various light diesel feedstocks was studied. The micro-pulsed pypolysis technique has been proved to be quick, economical, of small sampling volume, and capable of giving cracking response of feedstock structure and composition. It will find practical use in pyrolysis basic studies, feedstock evaluation and olefin production prediction.
