Recent studies suggest that the Mesozoic granitoids and the contemporary mafic and ultra-mafic rocks from the North China block and Dabie-Sulu orogenic belt have the similar Sr, Nd isotopic characteristics, and many of the granitoids and volcanic rocks exhibit some features of adakites.

近年来的研究证实，华北地台和大别—苏鲁造山带的中生代花岗岩与同时代的镁铁质超镁铁质岩有类似的Sr、Nd同位素特点，许多花岗岩和火山岩还具有类似埃达克岩的地球化学性质。

According the Sr - Nd isotopic and trace element characteristics and field observation, the mafic dikes are not affected by crustal material during emplacement.

根据Sr、Nd同位素、微量元素研究及野外地质观察，本区基性岩脉的岩浆在上升侵位过程中未发生地壳物质混染。

The paper discusses the relationship between science and hu manistic spirits from three aspects, namely, scientific moral , scientific goal a nd scientific value.

本文从科学道德、科学目标及科学的价值三方面讨论了科学与人文精神的关系。

The mineralogy, petrology, rare earth and trace element geochemistry, Re-Os and Sr-Nd isotopic geochemistry of the black shales and cherts of Yuretusi Formation at the bottom of the Cambrian in Xiaoerbulake and Shugeitebulake sections from northern Tarim Basin have been systematically studied. It was discovered that the high enrichment of some deep source metal elements in the black shales deals with the activity of hydrothermal fluid from the lower crust or upper mantal.

本项目对塔里木盆地北部肖尔布拉克和苏盖特布拉克两剖面下寒武统底部玉尔吐斯组富有机质黑色页岩和硅质岩的矿物学、岩石学、微量元素、稀土元素、Re-Os和Sr-Nd同位素地球化学进行了系统研究，发现该黑色页岩中部分深源金属元素的高度富集与来自盆地下部上地幔或下地壳的深部物源的热水流体作用有关。

The Sm-Nd isochron age (1182±50Ma) of Kangshan metamorphic complex has first been presented in the paper, which deny the tranditional point that the complex is Archean Taihua group. It's suggested that the plagioclase-amphibolite originates from subcon tinantal lithospheric mantal, assimilating and hybridizing minor crustal materials.

首次提供康山变质杂岩的Sm-Nd等时线年龄(1182±50Ma)，否定了康山变质杂岩是太华群的传统认识，并提出康山变质杂岩内斜长角闪岩原岩主要来源于大陆岩石圈地幔，同化混染了少量壳内物质。

Objective To evaluate the efficacy and safety profile of Q-switched 1064nm Nd:YAG laser for the treatment melasma.

目的评价调Q1064nmNd∶YAG激光用于治疗黄褐斑的疗效及安全性。

Resultsthe measl es immunization ra te of first dose and second dose were 86.2% and 60.4% respectively, the type(ele mentary school/kindergarten), school attribute(public/private), students' age a nd origin, parents' educational level were related to the immunization of secon d dose measles.

结果 深圳市入学、入园新生1剂次和2剂次麻疹疫苗接种率分别为86.2％和60.4％。影响学生麻疹2剂次接种的主要因素包括学校类别、学校属性、学生年龄、户籍、父亲及母亲的文化程度和地区差别。结论深圳市入学学生2剂次麻疹疫苗接种率不高。

During 1997, it continued to m a n a ge the New Horizons Vietn a mese Refugee Dep a rture Centre (for Vietn a mese refugees a ccepted for resettlement overse a s). The C A S deployed 40 members a nd eight perm a nent st a ff to m a n a ge the centre on a d a ily basis .

在一九九七年，民安队继续调派队内40名队员和8名常额职员合力管理新秀越南难民离港中心的日常事务(该中心专供容纳已获外国收容的越南难民)。

Cumulative NH4+-N is a good evaluating index of soil N-supplying not only for the first season crop, but also for two successive season crops. ND is more correct in revealing the potential mineralizable nitrogen when SON was regarded as mineralized N, although cumulative SON alone is not a good index for the potential of mineralizable nitrogen. And cumulative TSN could also be taken as an index for the potential mineralizable nitrogen to some extent.

淹水培养期间铵态氮累积量是评价可矿化氮的较好指标，不仅适宜于第一季作物，而且也适用于连续两季作物；SON累积量不能单独作为；SON累积量不能单独作为反映可矿化氮的指标，但用ND反映土壤可矿化氮潜势时，包括SON后更加准确；TSN在一定程度上能够反映土壤可矿化氮。

No fe a t of intelligence a nd ch a r a cter is so ex a cting as th a t required of two people who desire to live perm a nently together on a basis of a mity.

如果两个人希望永远不变地友善地生活下去，那么对他们在聪慧和性格方面所下的功夫，应当有无比的严格要求。
