以下是我写的，但老是觉得不对，想请高人修改！ A linear regression gives a good correlation with the experimental data in both A and B. According to Fig. 2 (A), a kinetics equation of the polymerization before the gel point can be evaluated by [...省略了] , where R is the reaction rate, K is the rate constant, and [I] is the concentration of the initiator. At 190 ℃, the value of rate constant is calculated to be (6.71 ± 0.26) × 10-2 min-1. The exponent of [I], 0.59, is approximate to the value of idea polymerization, 0.5. The exponent number obtained here is different from the value, 1, which was calculated by Spurr and Heydel et. al when peroxide compounds were used as initiators. The activity energy can be calculated from the linear fit of X vs. Y , where Y/X are the slopes of the lines of Figure 2 (B) and T is the absolute temperature. The calculated value of activity energy is 155.7 KJ/mol, which is close to the values of 36.0 Kilocal/mol and 121 ± 5 KJ/mol as reported. [ Last edited by qingshaojun0823 on 2009-8-20 at 17:07 ] |

The exponent number obtained here is different from the value, 1, which was calculated by Spurr and Heydel et. al when peroxide compounds were used as initiators. 这两句感觉整体上不大顺畅，据我揣摩，如果前后两句是同样的exponent number,则可以说： The exponent of [I], 0.59, which approximates the value of ideal polymerization,0.5, is different from the value 1 when peroxide compounds were used as initiators.(Spurr and Heydel et. al) 班门弄斧了！ |
