And a series of problems brought by the change of the site of Lanthanide and Actinide site was put forward.

并提出由于镧系和锕系位置的变化所带来的一系列问题。

The thirty rare earth elements are composed of the lanthanide and actinide series.

三十个稀土金属是稳定的La系和Ac系元素。

Structures of their lanthanide complexes which were obtained by simulating the pseudo-contact shifts of the complexes are presented.

在此基础上，通过对镧系离子诱导位移的分析和模拟，计算了氨基酸镧系离子配合物的13^C NMR作接触位移，模拟了配合物的分子结构。

Literatures of preparation of nanoscale lanthalide metal and lanthanide hydrides are not found.

我们尚未见到有关制备纳米镧系金属和镧系金属氢化物的文献报道。

One element of the lanthanide series and most of the elements in the actinide series are called trans-uranium, which means synthetic or man-made.

La系中的一个和Ac系中的大多数被人们叫做反铀元素，或者是人造的。

We will synthesize NO2A, PhNO2A and its dimer structure, and study the stability constants for lanthanides complexes and kinetics in hydrolyzing BNPP. And we also want to understand their differences in catalytic mechanism.

由前人的研究可得知，改变配位子的特性，或许可提高金属错合物对於磷酸酯键的水解效力，因此我们将比较NO2A 及 PhNO2A 对於镧系金属稳定常数，及其镧系金属错合物水解磷酸酯键的影响。

Ten strains of adult specific pathogen free chickens are inoculated with Laryngotracheitis virulent virus,to in vestigate the clinical signs and the pathological changes by autopsy.Inoculate SPF embryonated eggs of the ten strains with virulent infections bronchitis virus and vaccine ND virus respectively.

用传染性喉气管炎强毒株感染10个家系150日龄BWELSPF鸡，观察比较临床症状和剖检所见病变；用传染性支气管炎强毒株和新城疫疫苗株分别接种这10个家系的鸡胚，收获胚液并测定其毒价。

The doctor covered his normal eye for a long time and forced his lazy eye to see things.

oh， 我见过又d人系咁，但宜家至知呢d叫懒惰眼，我以为系"射里眼"既一种tim。。。。。。。。。。

Pot experiment with twenty-three open-pollinated Liriodendron chinense families from Liping of Guizhou at two nitrogen levels was conducted to study family differences of growth response to nitrogen supply.

选用来自贵州黎平马褂木优良种源的23个优树自由授粉家系，设置低氮素和高氮素2种水平的盆栽试验，以研究马褂木家系苗生长对氮素营养的遗传反应差异及所受遗传控制。

A pot experiment with twenty-three open-pollinated Liriodendron chinense families from Liping of Guizhou at two nitrogen levels was conducted to investigate family variation and inheritance of nitrogen absorption and utilization efficiency related to nitrogen supply.

选用来自贵州黎平马褂木优良种源的23个优树自由授粉家系，设置低N和高N2种N素水平的盆栽试验，以研究马褂木N素吸收和利用效率的家系遗传变异及N素水平的影响。

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％。
