Pure iron specimens were implanted by nitrogen ions with a fluence of 7×1017 ions/cm2 using ion beam implantation at an extracted voltage of 40kV.Composition and valence studies were carried out by X-ray photoemission spectroscopy;Glancing angle X-ray diffraction was employed to examine the phase transformation.

采用40kV的氮等离子体离子注入工业纯铁，注入剂量为7×1017ions/cm2，X射线光电子能谱研究表面注入层元素的成分和价态，X射线衍射分析注入层的物相转变，采用恒电位极化腐蚀试验研究了离子注入后材料在人工模拟体液中腐蚀行为。

Glassiness SiO2 layer is formed on the surface of coatings after exposure long time,which can isolation of oxygen and fills in interstice on the surface of coatings.

采用加入其他元素的方法使硅化铌改性可达到减少穿透硅化铌涂层微裂纹的生成和降低铌基材氧化速度的目的，但使用温度一般不超过1 300℃[1~3]。

Firstly, four geometric loop equations are set up by using vector method in complex number fields. Secondly, three constraint equations are used to construct the Dixon resultants, which is a 6×6 matrix and contain two variables to be eliminated. Extract the greatest common divisor of two rows and two columns of Dixon matrix and compute its determinant to obtain a new equation. This equation together with the forth constraint equation can be used to construct a Sylvester resultant.

首先使用矢量法和复数法建立4个几何约束方程式；再使用Dixon结式法对3个方程式构造一个含有2个变元的6×6 Dixon矩阵，提取其中2行列元素的公因式，将新矩阵的行列式展开后得到二元高次多项式方程，该方程与剩下一个方程使用Sylvester结式消去一变元，得到一元高次方程。

Using radiotracking, we counted the home range of Tree Sparrow is about 7600m〓 by 90% harmonic mean transformation.

北师大和首钢的环境状况有些类似，除了首钢麻雀的腹羽中Cd（p=0.026*）和Mn（p=0.007**）含量明显高于北师大外，其余元素的含量均不存在显著差异。

However, this co-operation is difficult, firstly because the elements of the factory are heterogeneous.

然而，这个合作是困难的，首先因为元素的工厂是异构的。

The mixture of images within each of my paintings is like a combination of elements in life.

我的每一幅作品里的图像混合都是生活元素的组合。

It is precisely this incommensurability of these elements of life that gives them the right not to he compared with any particular equivalent and that gives to life an irreplaceable charm and wealth.

恰恰是这些生活元素的不可相互化约性给予自身不能与任何特定等价物相比较的权利，并由此给予了生活一种无可替代的魅力与财富。

Our solution is another tip: using None as an index has the same effect as a missing index, so you can get the same functionality programmatically, i.e., when you are using a variable to index through a sequence but also want to be able to access the first or last elements

我们的方案是使用另一个小技巧：用None作为索引值，这样一来就可以满足你的需要，比如说，在你想用一个变量作为索引来遍历从第一个到最后一个元素的时候

The intersecting positions of aeromagnetic lines of different directions and depths were calculated, and characteristics of the integrated anomaly of different elements were described. The fuzzy membership map for the porphyry copper deposit was compiled.

通过模糊推理计算得到该区不同高度、不同方向航磁解译构造的交汇部位以及不同元素的组合异常特征，最终确定了该区可以发现斑岩型铜矿的模糊概率分布图。

This is used to calculate the astronomical elements Kepler track procedures used MAtlab prepared, Welcome oh.

这是用于计算天文中的开普勒轨道元素的程序，用MAtlab编写的，欢迎使用哦。

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。
