The fossils show what is known as an adaptiveradiation. This is biology-speak for a period of diversification so fast that the individual splits cannot be distinguished.
Emphasis is given to the characteristics of the dose response and time response relationships of adaptive response induced by extremely low dose rate ionizing radiation.
强调了极低剂量率电离辐射诱导适应性反应的可能及其剂量效应和时间效应关系的特点。

The Adaptive Time-delay Neural Network (ATNN) based on exo-atmospheric space point target IR radiation sequences is proposed in order to improve the recognition rate.
