同质

However, compared to other approaches, such as radioisotope tracers or mass analysis by mass spectrometry, NMR is sensitivity limited.

但是同其他检测方法相比，如放射性示踪剂或质谱分析方法，NMR的敏感性是有限的。

Analyses of the sedimentary textures and structures, ecological features of the faunas, stratigraphic distribution and occurrence environment of radiolarian cherts indicate that the Weimei Formation belong to littoral-neritic sediments as is the case with the quartz sandstone at the top of the Menkadun Formation deposited synchronously with it.

对维美组的沉积结构，构造，动物群生态特征，地层展布情况和放射虫硅质岩的产出环境等进行了分析，认为维美组与其南部的同期沉积门卡墩组顶部石英砂岩一样，同属典型的滨浅海沉积，晚侏罗世康马-隆子和北喜马拉雅地层分区为统一的滨浅海，不存在次深海—深海环境。

Since mineral N is assimilated more efficiently than N2, increasing soil N supply can lead to more photoassimilate being available for shoot growth and leaf development Trolley-Henry and Raper, 1986, Cassman et al.

由于矿质N比N2可以被更有效地同化利用，增加土壤氮素供应可以导致更多的光合同化物供给植株地上部分的生长和叶的发育（Trolley-Henry和Raper，1986，Cassman等1980）。

In assessing the rateable value, reference is made to other open market rents agreed at or around the date of valuation, for similar properties in the locality, with due adjustments to reflect any differences in size, location, facilities, standards of finish and management.

评估应课差饷租值时，必须参考同区类似物业於估价日期或接近该日期，在公开市场所议定的租金，并按面积大小、位置、设施、完工质素及管理水平的分别加以调算。

It was stripped down which has 105 2x9 groupset, lightweight wheels and the same nice rack with rear light.

它被剥离下来，其中有105 2x9 groupset ，轻质车轮和同尼斯机架，车尾灯。

Study of sapphirine and related mineral association in the high-grade region of the Larsemann Hills, East Antarctica, shows that sapphirine of the area is characterized by its magesio, iron-and aluminum-rich, but silico-poor feature, and the substantial intra-and intergrain changes in compositions. The change is mainly manifested by the Tschermark substitution + Si = 2Al.

通过对南极拉斯曼丘陵含假蓝宝石矿物及有关组合的研究，得知假蓝宝石的成分以富镁、铁、铝但贫硅为特征，其粒间及粒内成分的变化均较为明显，这种变化主要表现为以钙契尔马克代换+ Si = 2Al为主的类质同象置换。

Shrubs, trees, or herblike shrubs, precocious, coetaneous, or serotinous.

灌木，乔木，或草质灌木，先有花，花叶同放，或者先花后叶。

The iron replacement of sillimanite may somewhat affect the physic-chemical calculation and exert negative effects on sillimanite mineralization.

铁组分的类质同像替换对物理化学计算和夕线石矿化环境均有所影响，对夕线石晶胞参数a的影响很小，而对b，尤其对c的影响较大，与前人的结论有所不同。

In the solution of the singular integral equation, the influence at the center crack caused by the many remote cracks is considered approximately.

在此材料的力学分析中，平衡方程和几何方程和均质弹性力学中的相应方程全同。

The results show that the visible light response of the natural sphalerite sample results from the presence of substituting metal ions.

分析结果认为，天然内锌矿良好的可见光响应性能主要源自其晶格内丰富的类质同像替代离子。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
