1. 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。
2. Any element having an atomic number greater than 92; all are radioactive.
原子序数在以后的元素,都是放射性元素。
3. The program is applicable to all elements in the atomic number range from5 o 92 and has the capability to deal with 12 elements and 30 measuringpoints each time.
处理程序把MS-46电子探针输出的原始数据进行死时间和背景修正,得到强度比K,修正程序则把强度比K进行ZAF修正得到真实成分。
