针对当前求解大时间带宽积椭圆球面波函数(PSWF)无统一表达式的问题,通过对基于Hermite函数和Legendre多项式的显式渐近表达式求解误差的理论和数值分析,提出一种大时间带宽积PSWF及其微分算子特征值的显式渐近表达式,明确了大时间带宽积(c> 10π) PSWF及其微分算子特征值基于Hermite函数和Legendre多项式的精确高效求解的适用条件和计算方法. |
To address the problems that currently solve large time-bandwidth product prolate spheroidal wave functions (PSWF) with no uniform expression, an explicit asymptotic expression of the large time-bandwidth product PSWF and its differential operator eigenvalues is proposed. The expression is proposed using the theo?retical and numerical analyses of the solution errors of the explicit asymptotic expressions based on the Hermite function and Legendre polynomial. The applicable conditions and calculation methods of the large time-bandwidth product (c > 10π) PSWF and its differential operator eigenvalues are accurately and efficiently solved using the Hermite function and Legendre polynomial. |

性能对比分析结果表明,本文提出的表达式可保证各阶PSWF及其微分算子特征值始终满足误差要求,且正交性与能量聚集性具有显著优势. |
Results of the performance comparison analysis indicate that the proposed expression can ensure PSWF and its differential operator eigenvalues of all orders always meet the error requirements. Moreover, the orthogonality and energy concentration of PSWF signals have significant advantages. |

人工智能(artificial intelligence, AI)自1956年诞生以来,在60多年的发展历史中,一直存在两个相互竞争的范式,即符号主义与连接主义(或称亚符号主义). |
There have been two competing paradigms of artificial intelligence (AI) development since 1956, i. e. ,symbolism and connectionism (or subsymbolism). Both started at the same time, but symbolism had dominatedAI development until the end of the 1980s. |

二者虽然同时起步,但符号主义到20世纪80年代之前一直主导着AI的发展,而连接主义从20世纪90年代才逐步发展起来,到21世纪初进入高潮,大有替代符号主义之势. |
Connectionism began to develop in the 1990s and reached its climax atthe beginning of this century, and it is likely to displace symbolism. |

今天看来,这两种范式只是从不同的侧面模拟人类的心智(或大脑),具有各自的片面性,依靠单个范式不可能触及人类真正的智能. |
Today, it seems that the two paradigms onlysimulate the human mind (or brain) in different ways and have their own advantages. |

需要建立新的可解释和鲁棒的AI理论与方法,发展安全、可信、可靠和可扩展的AI技术.为实现这个目标,需要将这两种范式结合起来,这是发展AI的必经之路. |
True human intelligencecannot be achieved by relying on only one paradigm. Both are necessary to establish a new, explainable, androbust AI theory and method and develop safe, trustworthy, reliable, and extensible AI technology. |

本文将阐述这一思想,为叙述方便,我们称符号主义为第一代AI,称连接主义为第二代AI,将要发展的AI称为第三代AI. |
To this end,it is imperative to combine the two paradigms, and the present article will illustrate this idea. For the sakeof description, symbolism, connectionism, and the newly developed paradigm are termed as first-, second-, andthird-generation AIs. |
