Our calculation results indicate that the nuclear system is more regular in two-j shell than single-j case, and the nuclear system becomes more chaotic with the increase of excitation energy.

在粒子转子模型的单j壳和双j壳框架下，对原子核的转动能谱进行统计分析，并讨论了四极形变和转动惯量对系统混沌行为的影响。

The non-relativistic energies and wave functions were determined by Rayleigh-Ritz method. The relativistic effects, including the correction to kinetic energy, the electron-electron contact term, and the orbit-orbit interaction, Darwin term, and mass-polarization effect on the energies were calculated by using first-order perturbation theory. In order to obtain a more accurate result for the larger Z system, the quantum-electrodynamics correction should be included. This correction to energy can be evaluated for the valence electron by using a hydrogenic formula with an effective nuclear charge, Z. The ionization potential, the excitation energies and the fine structure split-tings for a lithium-like ion with higher nuclear charge (Z=26) were calculated.

非相对论能量用Rayleigh-Ritz变分法确定，包括动能修正、电子—电子接触项、轨道—轨道相互作用项以及Darwin项的相对论修正和质量极化项由全实加关联波函数的一阶微扰给出，量子电动力学修正由有效核电荷方法和类氢公式计算；给出了较高核电荷(Z=26)类锂体系1s^2nl组态的电离能、激发能和1s^2np组态的精细结构劈裂。

但是有些核技术没有石油核子分裂来获取的热能去煮沸水，使其产生蒸汽驱动蒸汽轮机然后传入发电机。

Poptosis-inducing factor is a mitochondrion-localized flavoprotein with NADH oxidoreductase activity, which is encoded by the nuclear gene. Following induction of apoptosis, AIF is released from mitochondria and translocated to cytosol, and then to the nucleus. The mechanism of AIF translocation from mitochondria to nucleus is still unclear. It has been suggested that translocation is due to the presence of nuclear localization signal.

bstract： AIF(apoptosis-inducing factor)为位在粒线体内膜膜上之蛋白质，在正常细胞中，能够藉由维持电子传递链复合体I的稳定性，进而影响细胞能量的产生及自由基的清除，并且也会维持粒线体的构造；反之，当细胞遭受到不当刺激时，粒线体膜通透性改变，使得原本存在於粒腺体间质中之AIF，被释放出来，进入细胞核内造成DNA片段化，进一步促进细胞凋亡。
