精细结构

With decreasing concentration of PAn, the ESRspectrum of PAn/NMP solution gradually exhibits a hyperfine structure composed of threepeaks indicating the interaction between the spin electron and 〓.

PAn具有顺磁性，固态的ESR谱是一线宽较宽的单峰，而其浓溶液的ESR是一线宽较窄的单峰，随浓度的降低，逐渐出现三重峰的超精细分裂结构。

Due to hyperfine structure of Rubidium atoms, the four-wave mixing effect exists in thermal Rubidium atomic vapor, which related to the third-order nonlinear effect closely. The Raman gain of the Stokes and anti-Stokes photons is observed by sweeping the frequency of the probe beam.

由于铷原子的超精细能级结构，在铷原子蒸气中同时存在与三阶非线性效应相关的四波混频现象，通过扫描探测光的频率同时观察到具有斯托克斯和反斯托克斯光子的喇曼增益现象。

In this paper,we investigate the structure of locally fine points and its applications to the abstract isopermetric problem .

在本文中，我们主要研究了局部精细点的结构，并讨论了其对抽象等周问题的应用。

The machine with novel structure, manufacturing fine.

本机结构新颖，制造精细。

Fine Chemicals for industrial structure, an important component, have gradually matured and is still a certain extent, has made great development.

多谢啦 精细化工作为工业结构中的一个重要组成部分，已渐渐走向成熟，并且还在一定程度上取得了巨大的发展。

According to the concept of substructure and Time domain FEM method, substructures time integration method is presented in this paper which is symplectic conservation.

对此，本文根据子结构概念和时间有限元方法，根据结构间界面的物理量关系划分子结构，提出保辛的精细积分子结构方法。

Our results reproduce all the structures near the higher energy edge shown in the experiment. The structures are attributed to the autoionization resonances from the detailed treatment of the photoionization process.

与实验结果的较好符合是由于对光电离过程的处理更精细的结果，在我们对光电离的处理中，比较完整地考虑自电离共振，这些共振对应较高能量处的光谱结构。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
