People through nuclear reactions, have been synthesized 17 kinds of atomic number greater than 92 of the transuranic elements, and thousands of The new kinds of radioactive nuclides, and by high-energy and ultra-high energy-ray beam and the interaction of atomic nuclei and found hundreds of kinds of short-lived particles, namely, baryon, meson, lepton, and particle resonance states of these particles has led to a new field of study - the birth of particle physics since the age of .70, nuclear physics has entered a deep development and wide application of new, more mature stage, on the one hand the development of particle acceleration and detection techniques, expanding people's research in nuclear means, the other hand, nuclear technology to serve the national economy, for example, for the development and utilization of nuclear energy to provide more accurate nuclear data; the use of isotope tracer technique diagnosis and treatment of disease; the use of radiation and irradiation preservation of food, irradiation breeding .

人们通过核反应，已经人工合成了17种原子序数大于92的超铀元素和上千种新的放射性核素，并且通过高能和超高能射线束和原子核的相互作用，发现了上百种短寿命粒子、即重子、介子、轻子和共振态粒子，对这些粒子的研究导致了一门新学科——粒子物理学的诞生。70年代以来，核物理进入了纵深发展和广泛应用的新的更成熟的阶段，一方面发展粒子的加速技术和探测技术，扩充人们研究原子核的手段，另一方面将核技术服务于国民经济中，例如，为核能的开发利用提供更为准确的核数据；利用同位素示踪技术诊断和治疗疾病；利用射线及辐照技术保存食品、辐照育种等。

6Although common prejudice still believes that the sole essential basis of our knowledge is given exclusively from outside and that "nihil est in intellectu quod non antea fuerit in sensu, it nevertheless remains true that the thoroughly respectable atomic theory of Leucippus and Democritus was not based 0 any observations of atomic fission but on a "mythological" conception of smallest particles, which, as the smallest animate parts, the soul-atoms, are known even to the still palaeolithi inhabitants of central Australia.9 How much "soul is projected into the unknown in the world of external appearance is, of course, familiar to anyone acquainted with the natural science and natural philosophy of the ancients.

虽然普通的偏见依然相信我们知识的唯一的本质的基础是来自外部世界，and that "nihil est in intellectu quod non antea fuerit in sensu，路斯帕和德谟克利特令人敬佩的原子理论并不基于任何对原子裂变的观察，而是基于"神话的"最小粒子的概念，这是作为最小的有生气的部分，灵魂的原子，这些也为中澳大利亚旧石器时代的居民所知。有多少"灵魂投射进世界外观的未知中，当然，也和任何人所熟知的古代人的自然科学、自然哲学相似。

In addition, the changes of molecular geometry, atomic natural charge and IR spectra of the reaction system during the crucial step of O to attack H showed that the rupture of C—H bond and the formation of O—H bond were concerted stepwise. Obvious changes of atomic natural charge happened to atoms C(1), H(11), O(28), O(29) and N(27). The bond lengths and bond angles related to these atoms were also varied greatly.

NO2中O进攻1-H决速反应过程中，分子几何、原子自然电荷及IR光谱变化表明， C—H键的断裂和N—H键的形成是一个协同过程；参与新键形成和旧键断裂原子C(1)， H(11)， O(28)， O(29)和N(27)的原子自然电荷及与其相关的键长、键角有明显的变化。
