摘要
本文用简化的中微子泄漏模式代替输运方程，计算超新星坍缩过程中的中微子变化，通过调节模式中的参数可改变中微子的俘陷密度，使之达到较为合适的值，还讨论了在中微子俘陷密度到达之前，特定密度区段（10^(-10)－5×10^(11)g／cm^3）内使电子俘获率有显著变化的一种参数方法及研究结果。
During a supernova collapse, instead of the transport equation, a reduced leakage scheme is used to calculate the change of the neutrinos. The trapping density can be adjusted by changing the parameters in the scheme and a reasonable value is obtained. Before the trapping density is reached, in the specific range of density (10^(10) - 5×10^(11)g/cm^3), we discuss a parametric method of making substantial change in the rate of electron capture.
