We review the properties of the heat kernel of strong elliptic operators and subelliptic operators with divergence form.
文章主要问顾了散度型的强椭圆微分算子和次椭圆微分算子H=-∑di,j=1icijj的热核的简单性质,总结了关于次椭圆微分算子的热核具有Gaussian上、下界条件的最新成果。
The possible reasons for the discrepancy between calculation results based on the statistical evaporation model and experimental data of giant dipole resonance of very hot nuclei are discussed.
讨论了引起统计蒸发模型计算结果与高温热核偶极巨共振实验结果之间存在差别的因素,对比了标准CASCADE程序计算结果与加入复杂粒子发射后的计算结果,计算显示复杂粒子发射对高温热核偶极巨共振的性质有影响。
The experimental studies and achievements recently made at the Heavy Ion ResearchFacility of Lanzhou(HIRFL) are reviewed with an emphasis on the three research fields: the study ofintermediate energy heavy ion collision and properties of hot nuclei, the synthesis and study of nucleifar from stability, and the applications of heavy ions.
本文简介HIRFL上中、低能重离子物理基础和应用研究的主要进展;着重介绍三个方面的研究:中能HIC和热核性质的研究,远离稳定线核的合成和研究,重离子束应用,并概述近期实验研究规划的初步建议。
Microscopic study of nuclear charge distribution in hot nucleus;
热核电荷密度分布的微观研究
It is indicated that each theoretical representative point located in the temperature plateau (temperature backhanding) of ALADIN caloric curve does not necessarily fall-down into the region of temperature plateau (temperature backhanding) of the caloric curve of corresponding projectile remnant (hot nucleus).
结果表明落在ＡＬＡＤＩＮ热曲线温度平台（温度扭曲）附近的弹剩余核（热核）的理论代表点，并不落在相应弹剩余核热曲线的温度平台（扭曲）范围内，从而对ＡＬＡＤＩＮ热曲线是否可作为核液气相变的证据提出质疑。
Since the fusion-fragmentation model includes both the dynamical formation and the statistical disassembly of hot nucleus, all the ALADIN data can be reproduced very well if the model parameter concerning excitation energy is somewhat adjusted.
由于非完全熔合碎裂模型可以将描述热核形成的动力学和描写热核瞬时多重碎裂的统计模型融为一体，所以只需适当调整与激发能有关的模型参数，就能很好地再现ＡＬＡＤＩＮ数据。
