In this paper, I attempt to address the problem of how to model the survival curve in the early lifespan years; the neonatal years. I present a general model for a two group population in which the first group represents early stage failure and the second group represents the classical Gompertzian failure. After calculating the instantaneous failure rate for this population, I compare it to the single group Gompertzian with log-linear instantaneous failure rate. The theoretical results are then compared to the known biological data. It is demonstrated that this new model embeds, within itself, a variety of the known biological survival dynamics.
在本文中，我试图解决如何对生命早期阶段（即新生儿期）的生存曲线进行建模的问题。我提出了一个针对两组人群的通用模型，其中第一组代表早期失效，第二组代表经典的冈珀茨失效。在计算出该人群的瞬时失效率后，我将其与具有对数线性瞬时失效率的单组冈珀茨模型进行比较。然后将理论结果与已知的生物学数据进行比较。结果表明，这个新模型本身包含了各种已知的生物生存动态。
