Seven thermo-labile organophosphorous pesticides, isocarbophos, monocrotophos, phospha-midon,methamidophos, acephate, phosmet and trichlorfon were determined by capillary gas chro-matography (GC) with FPD.

Study on the thermal instability of the active components in the gel of aloe arborescens Miller.;

It was theoretically proven that thermal instability exists during operations for thrust bearings based on an infinitely wide thrust bearing.

Based on the hydrodynamic instability and thermal instability theory, this paper theoretically analyses the instability of LNG under storage condition.

Analysis and determination of items amount of reaction coefficient for unsteady heat transfer calculation of wall;

This paper discusses the method of calculating the unsteady-state heat transfer of liquid in agitated vessel for multipass flow by the side of the vessel.

To discuss the general rule of calculating unsteady-state heat transfer in agitated vessels,and to expound the calculating method in this kind of the processes from several familiar,typical problems and their examples.

In this paper,in a horizontally located Rijke tube with an electric heat source,the sound pressure level of the tube for the position of the heat source was investigated and the thermoacoustic instability boundary for the heat source position was obtained.

In order to probe into the excitation mechanism of thermoacoustic instability in swirl combustors, an experimental setup has been built including an adjustable swirl combustor.

In order to study the mechanism of self-excited thermoacoustic instability,experimen- tal setup has been built.
