Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.

听起来尽管很奇怪，但是宇宙膨胀是基础粒子物理学的理论的科学推理结果，并且很多天文物理学家已经确认了它的正确性，在未来十年里是不会改变的。

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。

If you go to the first steps in the buildup of cosmic structures, then cosmology reacts to the microphysics of particles, which is quite remarkable.

The science that has found many of the answers to that profound and age-old question is particle physics: the study of those impossibly tiny particles with unbelievably strange names: bosons and leptons, quarks and neutrinos.

科学家们已经发现，能解开一些深奥而古老谜团的就是粒子物理学--它研究那些体积难以置信地小、名字不可思议地怪异的微小粒子：玻色子、轻子、夸克和中微子。

The Sommerfeld effect, a quantum-mechanical process that makes particles more likely to interact with one another in some circumstances and less likely in others, is mostly ignored in particle physics because it applies only in a limited range of conditions.

这个效应是一个量子力学领域的过程：在该效应作用下的粒子在一些特定情况下更易于相互作用，在其他情况下则相反。这种效应在粒子物理学里总是被忽视是因为它可以应用的场景及其有限。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
