According to the related theory about gas discharge, the numerical model of a gas discharge tube is established. With the help of particle simulation method, the curve of relationship between gas ignition voltage, gas pressure and electrode distance product is studied through computer simulation on physical process of producing plasma by DC neon discharge, and a complete consistence between the...

The use of the properties of the plasma generated inside the glow lamps or gas filled electron tube as an unconventional detection method for various physical effects was reported in several papers. For example in [1], [2] the experimental setups containing discharge tubes used to detect the external microwave field are presented. In this paper the effect of an external electrode on the electri...

A detailed study of the photochemical and discharge-driven pathways taken by gas-phase 1,3-butadiene has been carried out. Photolysis or discharge excitation was initiated inside a short reaction tube attached to the outlet of a pulsed valve. Bath gas temperatures near 100 K were achieved in the reaction tube by the constrained expansion of the gas mixture into the tube, simulating temperatures...

On the idealized situation of simply supported discharge tubes it is demonstrated how the discharge and suction pressures influence the resonance frequencies and thus the force transmission from the compressor to the compressor shell. The influence of flow velocity is also briefly discussed. With minor modifications, all results are also applicable to suction tubes in cases of high side compres...

A novel atomic emission spectrometry comprising laser ablation as a sampling source and hollow cathode plasma for the excitation of ablated sample atoms is proposed. In this arrangement, a conventional Grimm-type discharge lamp is employed, but the polarity of the power supply is reversed so that the cylindrical hollow tube acts as a cathode and the glow discharge plasma is produced within this...

We report numerical simulation of gas temperature of microwave discharge plasma of rare gases by weighted-DSMC method. Our numerical simulation showed that neutral particles are heated by collisions with ions. It is found that the average temperature becomes higher for heavier rare gas discharge plasmas, which agrees with our previous experiments. It is also found that ions are accelerated by a...

The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...
