| 释义 | deuterium noun[ U ] chemistry specializeduk /dʒuːˈtɪə.ri.əm/ us /dʒuːˈtɪə.tɪr.əm/ an isotope of hydrogen that is twice the mass of ordinary hydrogen: 重氢（氢的同位素，质量是普通氢的两倍） The nucleus of a deuterium atom contains a proton and a neutron.重氢的原子核由一个质子和一个中子组成。 Chemical elements actinium alkali metal americium antimony astatine berkelium brimstone calcium fluorine germanium lithium manganese nickel plutonium quicksilver selenium silicon sodium sulphur transition metal deuterium | American Dictionarydeuterium noun[ U ] us/duˈtɪər·i·əm/ chemistry a type of hydrogen (= gas) that is twice as heavy as the usual form of hydrogen Examples of deuteriumdeuterium At that time, the cross-arms end their collapse, trapping some of the deuterium filling inside. The instability conditions (34) and (35) simply state that the growth due to the fusion products exceeds the damping coming from the background deuterium plasma. Thermonuclear burn performance of volumeignited and centrally ignited bare deuterium-tritium microspheres. By electrolysis, the heavy water separated into oxygen, which collected at the platinum electrode, and deuterium, which accumulated at the palladium electrode. We use the solution for calculating the effect of particle trapping on neutron production for beam-heated deuterium plasmas. Also, in this plasma edge region, the temperatures of the carbon impurity ions and the deuterium ions are equal to each other. The existence of high energy ions is further confirmed by the occurrence of fusion reactions in deuterium clusters. For the deuterium-tritium fuel with a mass of few mg one gets an optimum at few hundred g/cc. Assessment of the interstellar processes leading to deuterium enrichment in meteoritic organics. We investigate the burning of the deuterium fuel in the cylindrical target. Thus, we re-examine theoretically the possibility of igniting hot spots in a super-compressed deuterium-tritium plasma. The field particles that are responsible for ' dressing ' the bare test particle are the ions and electrons of the background deuterium plasma. The heat flux from deuterium to the target and to the shell is assumed to be zero. The same ion temperature was assumed as a reasonable estimate for the case of deuterium plasma. The electron density in deuterium plasma has a parabolic profile with the minimum ne 2 10 17 cm 3 on the axis. These examples are from corpora and from sources on the web.
