The recent progresses in the study on the fluorescence of rare earth complexes and application for the determination of the rare earth elements and organic compounds, as fluorescent probes for bioactive materials analysis and as detection means in separation technology were reviewed in detail. In chapter two, the absorption spectra of the 4f electron transitions of the complexes of the neodymium, praseodymium, holmium and erbium with fleroxacin in the presence of CPC have been studies by normal and derivative spectrophotometry.

本文以稀土元素配位化学为基础，以导数吸收光谱技术和荧光光谱技术为研究手段，利用新一代喹诺酮类抗菌药物，抗凝血类杀鼠药物的化学结构特点和大环化合物冠醚与金属离子突出的配位能力，以分析应用为目标，系统研究了这些化合物同稀土元素形成的配合物的光吸收和荧光特性，通过对体系实验条件的优化，使体系的稳定性、选择性和灵敏度得到显著改善。

Research progress on the application of rare-earth compound in plastic was briefly reviewed,The rare- earth compound for stabilizer of PVC andβ- nucleator of PP were introduced.

重点介绍稀土化合物在PVC塑料中用作热稳定剂、在PP中开发成功一种高效的新型β成核剂。

The possible differential rotation among the layers of the Earth interior and its contribution to nutation, as well as the displacement profile interior, are studied, which provides a new method to study the differential rotation of the Earth cores.

讨论了地球内部可能的较差转动对章动的贡献以及地球内部形变场剖面，特别是核幔边界附近的低阶形变场的非线性特性，为研究较差转动提供了除地震学之外的另一种新的可能途径。

The interpretation and selection for different values of the Earth dynamical flattening will have to be approached in the construction of the future nutation theory of a non-rigid Earth.

在建立非刚体地球章动理论中，如何解释地球动力学扁率值的差异，如何选取地球动力学扁率值，还有待进一步的研究。

Phenomena such as precession the slow roughly 25 000 year cycle of movement of the direction of the Earth's axis and nutation the continual "nodding" of the Earth's axis due mainly to tidal forces from the Sun and Moon all have to be taken into account when defining a Universal Reference frame.

现象，如进动，慢，大约25 000年的周期，对地球的轴的方向运动，章动，不断"点头"地球的轴心，这主要是由于来自太阳和月亮，所有潮汐力量要考虑到当定义一个通用参考框架。

In view of the effective results about the long term disaster weather prediction based on the vari- ation of the earth rotation in the recent 10 years,the authors try to explore the deep reason of major disaster weather with the relationship among the earth nutation,rotation and atmospheric change.

鉴于近10多年来运用地球转速的变化做长期灾害天气预测取得的较好效果，试图运用地球的章动、地球转速和大气变化的关系，探索重大灾害天气的深层次原因。

Axis of maximum moment of inertia = the axis of figure: because the Earth is not a perfect sphere, but is physically an oblate spheroid, the position of the axis of figure is not a precise constant, but is affected by the constant change in the earth's distribution of total mass:(ie, by ocean tides, atmospheric cond- itions, plate tectonic movements, etc.).

轴最大转动惯量=形状轴：因为地球不是完全的球形，而是一个扁球体，形状轴的位置不是精确的常量，而是受地球总质量的分配持续变化作用：（也就是，受海洋潮汐、大气环流、地质板快运动等等）。

Arithmetic Analysis of Geocentric Vector Based on Earth Sensor for Spheral Model and Oblate Model;2. The accuracy of the measurements of the geocentric vector plays a key role in satellite navigation,but it is affected by the earth oblateness.

卫星利用紫外敏感器和星敏感器进行自主导航的方法中地心矢量的测量精度是影响导航精度的重要因素之一，而地心矢量的测量又受到地球扁率的影响。

It is eminently fitting for the Roman pontiff to carry out the duty of a provident shepherd, in order to care for and keep safe the Lord's flock entrusted to him by God, since, by the will of the supreme ordinance by which the things of heaven and of earth are arranged by ineffable providence, he acts on the lofty throne of St Peter as vicar on earth of Christ, the only-begotten Son of God.

这是非常恰当的罗马教皇履行义务的节约牧羊人，为了照顾和保持安全的上帝的羊群托付给他的上帝，这是因为，由最高法院将在该条例的事情天堂和地球是无法形容的普罗维登斯安排，他的高尚行为的圣彼得宝座的副主教基督的地球上，唯一的，上帝的独生子。

There is the only way to regulate the earth's own orbit space, that is earth's own major earthquake.

而调节地球自身运行轨道空间的，只有一种方式：那就是地球自身发生的大地震。

I can not negligent, he should do what?

我不能不在意了，他要做什么呢？

It is very dangerous to swim in the river alone.

一个人到河里游泳是很危险的。
