| 释义 | xenon noun[ U ] uk /ˈzen.ɒn/ us /ˈzen.ɑːn/(symbolXe) a chemical element that is a gas with no colour or smell. Xenon does not react with other elements and is used in some types of light bulb.氙 Chemical elements actinium alkali metal americium astatine berkelium brimstone bromine calcium fluorine germanium iodine lithium manganese nickel plutonium quicksilver selenium silicon sodium transition metal Examples of xenonxenon We note that the highest value corresponds to the rate coefficient of metastable xenon ionization for this type of gas mixture. It becomes then a fast pusher for the xenon. Xenon atoms are excited by collision of electrons. Some cells are operated with a tri-mixed gas, which consists of 70% of helium, 27% of neon and 3% of xenon. This difference is because xenon has deeper inner shells than copper with ionization potentials of those levels four times higher. Just as water and xenon have different nucleation barriers to boil or condense, so also do simulations and real proteins have different absolute folding barriers. The samples were irradiated at different doses with a xenon lamp. We mixed xenon gas in methane to compensate for the effect of nonlinear refractive index. Xenon and argon have been used for the experiments at a constant backing pressure of about 1.5 bar. It is therefore useful to estimate the number of excited xenon atoms in this level. A xenon flash lamp acts as an optical backlighter and illuminates the target from the rear side. The ionization energy of the lithium ion is much smaller than that of xenon and tin. The thruster plasma is a partially ionized gas, consisting of electrons, ions and neutral xenon particles. The shock is driven by a piston made from plastic and gold in a cell filled with xenon at 0.2 bar. Experimental-observation of a radiative wave generated in xenon by a laser-driven supercritical shock. These examples are from corpora and from sources on the web.
