Typical plot of minimum value of nτ necessary for net release of energy versus ion kinetic temperature in a mixture containing equal amounts of deuterium and tritium. (After J. M. Hollander, ed., Annu. Rev. Energy, 1:213–255, 1976)
Examples of branched polymers. (a) Branched polymer (if arms are of composition similar to backbone) or graft polymer (if compositions are different). (b) Star polymer. (c) Comb polymer. (d) Dendritic polymer.
