Absolute Frequency Stabilization of Diode-laser-pumped Nd:YAG Lasers to Hyperfine Transitions in Molecular Iodine. Opt Letters 1992; 17: 1204

我们认为，P(52)32-0完全可能成为未来的国际推荐谱线，在532nm Nd：YVO4/KTP倍频激光的调谐范围内使用。

Our research showed that the genetic variation of raptors and nighthawks was abundant and that the number of transitions and transversions in 12S rRNA and 16S rRNA genes increased gradually with p-distance and appeared not to be saturated, which indicated the phylogenetic relationship made in this study was really reflected.

所采用的12S rRNA和16S rRNA基因变异丰富，研究表明该基因的转换数和颠换数随着遗传距离的增加呈稳定性增长，未出现饱和现象；因此该基因数据能够提供有效的遗传变异信息，反映出较高真实水平的鸟类系统发育关系。

The absorption of this radiation in various lines followed by cascade transitions to lower levels might ultimately produce an anomalously high population for the excited levels of these molecules.

在各谱线处对这种辐射的吸收以及接着向低能级的级联跃迁最终可能使这些分子的激发能级产生异常高的粒子数。

Based on the similarity of structure between the antifluoride and alkali antimonide, the possible transitions taking place in the Brillouin zone corresponding to the structure in the optical spectra are identified for Na_2KSb,Css_3Sb and K_2CsSb cathode.

利用反荧石结构和其结构的相似性，确定了Na2KSb、Cs3Sb和K2CsSb阴极在光谱结构上对应布里渊区中发生的光学跃迁，发现多碱阴极的跃迁更接近晶态，而Cs3Sb和K2CsSb阴极和非晶态的非常类似，在Na2KSb中出现的来自Δ、Σ方向跃迁形成的极大峰并不出现在Cs3Sb和K2CsSb。

In this thesis, the contribution of electric quadrupole (E2) and higher pole transitions to the opacity of hot and dense plasmas of element aurum is taken into account by using an average-atom model.

因此本文在有心力场单电子近似下，利用平均原子模型研究了电四极及更高阶跃迁对金元素的高温稠密等离子体辐射不透明度的贡献。

In the first article of a section entitled "Transitions from Authoritarianism?"

书的第四部分为"独裁主义的转型"。

Some are in life transitions, among them a baby-faced 50-year-old Silicon Valley engineer, a recently divorced man, who said that the practice of manually fixing his attention on a tiny spot of a woman's body improves his concentration at work.

其中一位50岁却长着娃娃脸的，不久前离了婚的硅谷工程师声称，手动地将自己的注意力集中在女人身体上某一小部位上，这样做有助于提高工作中的注意力。

The fermion environment is considered from zero temperature to the critical temperature. It is show that the decoherence of the two-level system may also act as the witness of the environments phase transitions, which is similar to the relation between quantum phase transitions and decoherence in the former study.

对于一维XY自旋链系统，二粒子系统的纠缠度会在自旋链的量子相变临界点附近发生剧烈的变化，这种剧烈的变化正是量子相变的一种外在体现。

The diversifications of abnormal peaks of dielectric constant and loss were clarified by space-charge model, and during phase transitions, the common-body contradiction was proposed qualitatively between the effect of space-charge model with hopping cation by changing frequency and that of current-carrier scattering by their structural transitions, their co-contributions decided the change behaviors of dielectric constants and loss.

以不同化学微畴的空间电荷模型讨论了相应介电峰和损耗峰的变化机理，提出在频率改变时畴中阳离子跃迁形成空间电荷的效应和相变所带来的载流子散射效应是一对矛盾共同体，它们间的贡献对比决定了介电常数和介电损耗的变化行为。
