The results showed that the δ13Corg values of plant in Tamarix L. populations are positively correlated with that of surface soil in the Tarim Basin, indicating that the interfering factors of microorganism and hydrophyte could be ignored in the arid regions.

结果表明：塔里木盆地柽柳属种群中植物与表土碳同位素组成之间存在显著相关关系，说明在干旱地区土壤中微生物和水生生物等的干扰因素可以忽略，其现代土壤的同位素组成只与地表相应的主要植被类型有关。

In our best cases in ilmenite, isotopic variation in 46TiO/48TiO the within run (1000 sec) scatter was only 0.7%(1σ), which is within factor of 2 of statistics limit. And the reproducibility in the case of 46TiO can be as good as ≦1%.

The mechanism to form HD+2,H+3 and D+3 from RF ion source is analyzed by experimental study of the interaction of these ions with solid foils. The structural pattern of HD+2 and the mean internuclear separations are determined using the Coulomb explosion technique.

从分子离子H+3及其氘化同位素分子离子D+3和HD+2与超薄固体膜相互作用发生库仑爆炸为基础，分析讨论了H+3，D+3和HD+2三种分子离子的形成机理，根据产物能谱分布，利用库仑爆炸技术确定了同位素分子离子HD+2的结构形式，给出具体核间距数值。

Theoretical study on the nuclear fusion mechanism of deuterium clusters aroused by Coulomb explosion s with femtosecond intense laser;2. The structural pattern of HD_2~+ and the mean internuclear separations are determined using the Coulomb explosion technique.

从分子离子H3+及其氘化同位素分子离子D3+和HD2+与超薄固体膜相互作用发生库仑爆炸为基础，分析讨论了H3+，D3+和HD2+三种分子离子的形成机理，根据产物能谱分布，利用库仑爆炸技术确定了同位素分子离子HD2+的结构形式，给出具体核间距数值。

It is estimated that D atom prefers to takeposition of 3Ti-1Mo tetrahedron interstices, whereas H atom prefers to take 4Ti position.

Mo含量为0.03时，合金的分离因子约等于1.0，这是具有反同位素效应的纯钛氢化物和具有正同位素效应的Ti-Mo合金氢化物共同作用的结果。

Through K-Ar isotope age study in pillow basalt,has gained the isochrone age is139Ma.The age is the formation age of pillow basalt.

在枕状玄武岩中获得K－Ar同位素年龄为139Ma（测试单位：宜昌地质矿产所同位素室），因此确定其时代为晚侏罗世晚期。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

Carbon isotopes show a pattern, but it is somewhat more difficult to interpret than the oxygen isotope pattern.

碳同位素显示的格局，但它是较为困难的解释比氧同位素模式。

In Cenozoic rocks, its position in the crossplot would indicate that meteoric waters rich in coastal photosynthetic C were a component of the pore fluids during lithification.

这些新生代的岩石在图1中的位置显示大气水在海岸富集了大量的光合作用碳同位素，这些同位素代表了成岩过程中的孔隙流体的组成。

Marine δ13C may have varied in the Neoproterozoic, but this could only be deduced following careful consideration of large isotopic changes that occur during lithification and later alteration.

大量的进行光合作用的生物曾经广泛出现并且制造了足够的光合作用碳，这些碳同位素后来进入了海岸地下水并且沉积形成了具有独特碳同位素特征的海相碳酸盐。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
