Data shows, chinese Internet already had the fictitious money dimensions of one billion four hundred and ten million and sixty-five thousand four hundred and eight yuan of RMBs every year, if press 20% tax rate computative, academic admiral produces the revenue income of 2 billion yuan of above.

数据显示，中国互联网每年已具备百亿元人民币的虚拟货币规模，若按20%税率推算，理论上将产生20亿元以上的税收收入。

This is because there are two shortcomings inherent in coding method based on difference operators:(1) chain is long and consequently speed of recognition is low;(2) features of waveform such as concavity and convexity can not be described.

该方法与以往基于差分因子进行编码的方法相比较，具有以下优点：（1）链表达短，进而使后续的剖析速度大大加快；（2）不但注重波元的升降特征，而且还注重波元的凹凸特征。

Since the conics are used as the calibration primitives, which are global features, the proposed technique is more robust and stable.

由于该方法利用二次曲线作为标定基元，简化了基元对应问题，并且精度和稳定性都比较高。

Computational algorithms of BEM for both multi connected domain and composites with particle of arbitrary geometry are derived.These BEM algorithms are used to calculate the temperature distributions for composites with both single-particle model and multi-particles models.

首先推导了多连域和含任意形状夹杂复合材料温度场问题的边界元计算格式，随后采用边界元法计算了具有不同形状和界面性能的单夹杂和多夹杂模型内的温度场。

In contrast, the constant yuan value of an item is the current yuan value adjusted for inflation.

相反，某商品的定值元价值是其现值元价值扣除通货膨胀后的价值。

In this thesis, a semi-classical model of the force on an atom is used to describe the motion of a two-level atom interacting with a standing wave laser field. The velocity dependent force and momentum diffusion are derived through optical Bloch equations by using the matrix form of the continued fraction technique. By investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom.

本文利用半经典理论，从二能级原子在激光驻波场中所满足的运动方程出发，推导出密度矩阵元所满足的递推关系，利用矩阵连分数方法求解出密度矩阵元，从而求出依赖于原子运动速度的光压力与动量扩散系数，通过讨论原子在激光场中的动力学行为，为原子在激光场中被囚禁、形成原子列阵以及可控制的量子态，从而为量子信息处理提供理论基础。

The limitations of those principlesare stated and modified potential energy theorem with weak continuity is given which canbe applied to non-conforming finite elements.

给出了它们的限制范围，并给出在弱连续条件下的势能原理，而它是协调元和非协调元的共同基础。

The discrete element method and the finite element method have their own advantages and weaknesses. Basically, the DEM was developed for predicting the failure problems accompanying with the transition from continuum to non-continuum media. However, it is not accurate to calculate the problem of continuum media. The FEM may forecast the failure area of the material reasonably, while it is hard to calculate the failure process in brittle media. Therefore it becomes a good choice to combine the two methods to construct a hybrid model.

离散元法和有限元法等数值计算方法各有其优势，同时也都存在不足之处：离散元法适于处理由连续介质向非连续介质转化的破坏问题，但对于连续体计算结果精度不高；有限元法适于预测材料破坏的区域，但难以直接用于计算脆性材料破坏过程，因此将两种方法结合可以形成一种较好的混合模型。

Each pixel on multispectral and hyperspectral imagery can also be regarded as one vector and the whole image is a convex cone formed by a number of nonnegative discrete vectors,so endmember selection is equivalent to search for the vertices of a convex cone.

遥感图像中的每个像元都可以看作一个多维向量，整幅影像看作由离散的非负向量构成的凸锥，通过寻找凸锥的角点来自动获取图像的端元。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
