We can draw a conclusion from the comparison between natural number and meaning that both exactness and fuzziness are meaningful only lying in a cognitive field and the former is relative, which can only exist at a static and close system; while the latter is universal, which is the result of being the cognitive reference point. Both exactness and fuzziness come from the interaction of the cognitive subject and object, and they are dialectical and unitive, based on the historicity and infinity of human cognition, which determines what we can do, is just to hold the continuum by discreteness and infiniteness by definiteness.

从自然数与意义对比得出的结论是：精确性只存在于一个静态的封闭系统中，是相对的，模糊性是语言充当人类认知参照点的结果，是绝对的，这两个概念都只有放在某个人类认知场才有意义；精确性和模糊性都来源于认知主体和客体的相互作用，它们是辩证统一的，其辩证统一的基础在于人类认识的历史性、无限性决定了人类只能够用离散来把握连续、用有限去追求无限。

Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

347关于宇宙日益扩大进化的冥想：新月期的月亮，即使在近地点也看不见。从地表向地轴挖掘纵深五千英尺的圆筒状垂直轴，一个观察者呆在轴底儿上，就连白昼也辨认得出那漫无止境、网络状、亮光闪闪、非凝结性的银河。天狼距地球十光年（五七、000、000、000、000英里）；体积大于地球九百倍；大角；岁差运动；有着"猎户"腰带、六倍于太阳的"伐二"以及星云的猎户座，星云中能容纳我们的一百个太阳系；死去的和新生的星宿，例如一九0 一年的那颗"新星"我们的太阳系正朝着武仙座冲去；所谓恒星的视差或视差移动，也就是说，实际上恒星是在不断地从无限遥远的太古朝无限遥远的未来移动着。相形之下，人的寿命充其量才七十年，不过是无限短暂的一段插曲而已。

Comparison with the classical fourth-order LWC scheme shows that the NAD-type methods have many advantages. They can generate clearer snapshots of wave fields without any visible dispersion. To obtain the results without any numerical dispersion, the time cost by the LWC schemes is about 559, 1222 and 1955 times of that taken by ONADM, RNADM and SNADM, receptively. Besides, the storage space of ONADM is roughly about 3.3% of that needed for the fourth-order LWC scheme, while of RNADM and SNADM is about 5.8‰.
