【正】 By using the method of double ratios of isotope yields,the nuclear temperature isextracted in the reactions of 30MeV/u <sup>40</sup>Ar bombarding <sup>58</sup>Ni and <sup>115</sup>In targets.The yields areintegrated over the energy spectra of the fragments emitted at forward angles.The dependenceof the temperature on emitted clusters,emitting angles and targets is discussed.
