结果表明使用X光透镜的微束X射线荧光分析方法可以实现植物样品的微区分析，有助于进一步了解植物的生长与元素迁移的关系。

We utilized the electrochemistry, scanning electron micrograph, X-ray fluorescence spectroscopy and X-ray photoelectron spectroscopy to demonstrate this mechanism.

我们用电化学方法、扫描电镜、X射线光电子能谱和X射线荧光光谱法对此进行了证明。

If ris also irreducible in Z_nand f~n~κ≡fmodn,r(xfor all f∈Z_nthen we call n a Carmichael number of orderκmodulo r.Denote the set of all such numbers by C_κ,r(x.Define C_κ=∪_r(xC_κ,r(x,where rpasses through all monic irreducible polynomials over Z of degreeκ.We call elements of the set C_κCarmichael numbers of orderκ.ZHU and SUN[Journal of Sichuan University,42;1(2005), 47-51]first gave a necessary condition for Carmichael numbers of order 3.Then they gave a sufficient condition for Carmichael numbers of order 3,but did not find any such numbers less than 10~8 satisfying the sufficient condition.At last,they asked three questions;1.is the necessary condition also sufficient?

f∈Z_n，就称n是模r的κ阶Carmichael数，用C_κ，r(x表示所有这种数的集合，定义C_κ=∪_r(xC_κ，r(x，这里r跑遍Z中所有κ次首一不可约多项式，C_κ里面的元素就称为κ阶Carmichael数，C_κ称为κ阶Carmichael数集，朱文余和孙琦[四川大学学报，42；1(2005)，47-51]首先给出了3阶Carmichael数的一个必要条件；然后又给出了这种数的一个充分条件，并发现10~8内没有满足此充分条件的这种数；最后他们提出三个问题；一、问必要条件是否也是充分的？

We suppose that C is a category with involution *, a is a morphism of Category C, h and k are inversive symmetrical morphisms of category C. If there is a morphism x, satisfyingthen x is called a general Moore-Penrose inverse of a on morphism h and k .

设C是具有对合*的范畴，α是范畴C的态射，h，k为范畴C的可逆对称态射，如果存在一个态射x，使得则称x为α的关于h，k的广义Moore-Penrose逆，记为α_~+。

We also know that ArcSin is an odd function and therefore the second order term B*X*X is of no use in the approximation.

我们也知道 ArcSin 是一个奇函数，因此二次项 B*X*X 在近似中没有用。

X .. Open interval with lower bound x

x 。。||开放的间隔区间，下界是 x

Let X be a finite set and let be a family of distinct subsets of X; then the ordered pair H= is called a hypergraph.

设 X 是一个有限集合且ξ是 X 的相异部分集合所形成的集合族；则序对 H =称为一个超图形。

Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.

对有颈部外伤史的病人常规行X线检查，然后根据寰齿间距和齿突侧块间隙的结果，行下一步CT检查或者MRI检查，指导临床治疗方法的选择。X线侧位片观察寰齿前间隙(为寰椎前弓后缘与齿突前缘距离)，齿状突后倾角(齿突纵轴与枢椎体纵轴的夹角)；开口正位片上测定齿突侧块间隙。

An analytic solution of kinematic model was obtained via Lie transformation group. It shows that the velocity of particles flow is maximum when x=0. Through locating the maximum particles velocity distributing line and taking the line as the origin line of x coordinates, the modified kinematic model could simulate the eccentric discharging well.

通过Lie变换群得到"运动模型"的解析解，发现x=0时颗粒的垂直速度达到最大值，由此在确定颗粒最大速度分布线的基础上移动坐标使该线上x值均为0，对"运动模型"进行了修正，可以反映壁面对颗粒运动的影响，所得计算结果与实验测定吻合得很好。
