The Curies tried to compare their rays with Becquerel's rays, to find the commonalties.

居里夫妇试着对这两种元素的射线与贝克雷尔的射线进行了比较，以便找到具有放射性的元素郡体。

In Part I, the biharmonic equation are chosen, and the boundary peanlty finite method using piecewise cubic Hermite elements is used to seek their approximate solutions, in particular satisfying the derivative and periodical boundary conditions.

在第一部份里，选择使用片断三次 Hermite元素的边界惩型有限元素法来求解满足边界导数条件和边界周期条件的重调和方程式的近似解。

Based on the relationship between two views indicated as 2-D projective collineation, prediction problems about points or lines from two views or three views can be solved effectively.

基于2-D射影对应所描述的视图关系，可以有效解决双视图和三视图条件下的点元素或线元素的预报问题。

The column of this matrix is the angles between string and horizon of each element resulting from a unit moment applied at an element.

矩形的专栏是在每个元素之间串和天际的角度起因于单位片刻在元素的使用。

Hydrogen always has valence 1, so other elements' valences equal the number of hydrogen atoms they combine with.

元素的特征价数是以该元素一个原子可结合的氢原子数或可从一化合物中置换出的氢原子数来表示。

This method is a good way to find additional descendant elements with which to process.

这个函数是找出正在处理的元素的后代元素的好方法。

The change of fibers and hydroxy rubber in surface is determined by ESCA and SEM.

用电子能谱仪和扫描电镜对改性后的纤维和丁羟橡胶表面进行了测试，结果表明：C元素的含量明显下降，N和O元素的含量提高，纤维表面活性提高。

When DTD is available, XSLC can analyze the data model and encode elements according to the relationship of father node and son node, compress data part according to its type, and support query operations app-lied on compressed files, as for only one time of scanning data is needed, all the processes can be implemented in XML data stream environment.

提出XSLC（XML stream layered-coding compression）算法，通过预先扫描DTD对数据模式进行分析，继而根据元素的父子关系进行子元素层面的编码；同时根据数据类型进行数据压缩，能够在压缩之后的文档上进行查询，因为仅需一遍压缩扫描所以可以应用于数据流环境。

After the ferromolybdenum was dissolved completely in nitric acid at low temperature,adding internal standard elements of ~(45)Sc,by use of internal elements calibrated method,the content of Sb,Cu,Sn,Si and P in ferromolybdenum is determined directly by ICP-MS.

将钼铁样品用HNO3低温溶解完全后，加入内标元素45Sc，采用内标法，用ICP-MS仪进行测定。文中讨论了基体钼对测定的影响。本方法的加标回收率为98.0%~102.5%，相对标准偏差RSD为1.6%~3.5%。本方法具有简便、快速、准确等特点，可用于钼铁样品中微量杂质元素的分析

To minimize the contamination of detrimental elements such as sulfurand chlorine, a two-step sol-gel process was successfully developed to synthesize SiC precursors with oxalic acid and hexamethylenetetramine HMTA as the catalysts, which are free of sulfur and chlorine. Tetraethoxysilane TEOS and phenolic resin were used as the silicon source and carbon source, respectively.

为了尽量减少硫、氯等有害元素的含量，本文用不含有害元素的草酸和六次甲基四胺HMTA为催化剂，正硅酸乙酯TEOS为硅源，酚醛树脂为碳源，成功探索出了制备SiC前驱体的两步法溶胶-凝胶工艺。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
