plasma temperature measurement

Based on the fluorescence emission spectrum line intensity is proportional to the number of excited particles principle, by measuring the emission of different excited state level of the relative intensity of fluorescence spectrum of Ne gas pulse corona discharge plasma electron temperature with the average peak voltage, the sample pressure change and the effective time of the electron temperature behavior was studied. The results showed that the average electron temperature with the discharge peak voltage, the sample showed a nearly linear pressure trend; and effective electron temperature versus time before the pulse corona discharge current changes.

With the rapid economic and industrial development, environmental pollution is getting worse. Pulsed corona discharge plasma activation of its low energy consumption, high efficiency, wide application, etc. ll.2】, in air pollution control (mainly the desulfurization denitrification) aspects of attention has been widespread. at home and abroad of scholars in this field is more concerned about the end result, namely, the removal efficiency of pollutants 13-6], but excited by pulse corona discharge for gas discharge electron temperature, excitation temperature and electron density of the Vibrational study parameters such as little, and these parameters for the study of pulse corona discharge mechanism and to further improve the pollutant removal efficiency are crucial. Pulsed Corona Discharge Plasma as a one of the parameters of the electron temperature (Wu), to reflect the movement of electrons in gas discharge .

The electron temperature of Ne plasma is obtained in negative pulse corona discharge by measuring the relative fluorescence emission intensity of different energy levels. The change tendency of the electron temperature of Ne plasma with discharge voltage, sample pressure and time is studied. The results indicate an increase of the average electron temperature during the pulse corona discharge when increasing the discharge voltage or decreasing the sample pressure. The available electron temperature and discharge current do not change synchronously with time.

Time and the Earth by celestial coordination of space-time resonance spiral to achieve and complete body of knowledge spiral phase kernel carcass laugh, to use knowledge of the universe space-time emission of light spin energy group, is to build a knowledge model of the human body map of the energy exploitation of cosmic time to complete the human body energy absorption into the disc space, knowledge of life caused by spiral revolutionary scientific experiment in human evolution at all. Therefore, building model pyramid system of the Establishment, must be a quantitative change on the human ability to form a qualitative change from the Buddha-body of the vacuum into a big discussion is closed.
In fact, the unity of the universe, is necessarily a physical and chemical luminescence helix between the true unity. That is closed in a vacuum field of quantum mechanics can be unified on the theory of relativity. This is a theory of human subjects in view of quantum theory at the micro and macro movement of celestial objects to achieve a unified theory. That all the spin of the vacuum material objects alone constitute the main set closed.
Space-based physics, celestial light of the knowledge spiral pattern of the large ones in the channel re-hui in the body to produce substances in the body of the energy of the main set. That the generation of stars is the energy field in the material universe time as shown in the formation of the inevitable result of the vacuum is closed. Vacuum closed closed produces the material body of the vacuum between the stars and other substances the body strong tradition, which constitutes the body of different stars and other material relative to Ren Jian stone that closed the vacuum of the vacuum closure of nuclear material to form the body weight groups of nuclear spiral gravity stars closed, thus forming the universe space-time structure of matter in clumps of varying sizes. Mass structure of these substances produce further movement in space and time under the situation of the collision combination of state of current week, which will form a larger mass of a combination of levels. This time the Spiral in the collision, AV materialized collision structural system, structural system to quantify the TV, the spiral phase method as-kun, is bound to form a structure such as a tornado-shaped group of stars with the energy field - such as the Milky Way's spiral structure chronotope cubic shape. As shown, the Bank of nuclear generation, is necessarily a vector of the light of all the spiral volume materialized.
Tianyi twist, the body of the universe space-time volume and opening up the spiral movement - that is the root of the Milky Way campaign streamer contains common sense, necessity and structure of celestial bodies can be materialized space between sports stars and other material related to group structure. Spiral galaxy field by the space-based second row of empty cloth push rotary energy flow - the twelve constellations of space-time field force of energy dominate.
Space-based movement, that Xingyu second field energy movement. Or pushing the twelve constellations of field rotation movement. Daheng constellation can also be said to exercise - that is the Big Dipper light exercise. Sun times a week for sports stars around the large generation of human civilization root group. During the 129,600 year cycle. Among them, a seasonal calendar as usual every change of 10,800. Into a seasonal, but also with a solar term cycle, the 5400 changes in the solar term weeks streams. The age of the solar cycle time and space, followed by comparison with the Earth reference flow changes weekly round solar terms, can be described as a fan is to expand the level of the talk. That the second set, the Chinese solar terms week compass stream's change. Compass three changes in China, Heaven, Earth, three sets, the earth, the sun, the galaxy three cycles of natural change. Therefore, an auspicious beginning, the three settled when the orderly exploitation of the human culture. Specific solar term is to make inference, see, "Huang ji jing shi" Shao Yong was.
Space and time in human history, calendar 5400 delivery of a major change in solar terms, the same as that of the Earth round flow changes in solar terms week delivery. Only when the solar term delivery, the earth's "Great Flood" and the like natural disasters, changes of the weather than we usually larger Bale. Such as "Da Yu" during the scene. Earth quake, and the Earth within the structure of knowledge related to changes in the vacuum closure. The natural structure of the Earth system, the formation of veins, and the earth closed body of the vacuum within the vacuum of nuclear fusion closed relationship between the relevant energy release. Closed closed vacuum vacuum core, is a structural system of matter the energy of the wave vector trace the formation of large red bound to the origin of the energy of stars. Therefore, the basic principles of flying saucer, is necessarily a natural knowledge structure that materialized - screw vacuum closure to meet changes in the body.
