两维的

By taking the strategy of uniting geometry with algebra and using the method of minimal value, the distance problems between a line and a line in four dimensional space are investigated and the caculation formula are given.

用形数结合的观点和极小值法，研究了四维空间中两直线间的距离问题，并给出了相应的计算公式。

The topics covered in these sections are the geometric interpretation of systems of linear equations, the classification of finite symmetry groups in two and three dimensions, the exponential of a matrix and its application to solving systems of first order linear differential equations with constant coefficients, and Hurwitz's theorem on the composition of quadratic forms.

这些条文所涉及的主题是线性方程组的几何解释，在两个和三个有限对称群的分类方面，一个矩阵及其应用，以解决一阶常系数线性差分方程，系统指数赫尔维茨定理在二次形式组成。

Two SP1-like elements and half of binding motifs of RAR are found in the 119 bp region from -nt. 325 to -nt. 207 upstream of the first ATG. An AP1/cAMP like reaction element is found in the 113 bp region from -nt. 206 to -nt. 94 upstream of the first ATG of the CK13 gene 5' flanking region. We didn't know the reaction element CTGAATCA between -nt.

仔细分析CK13基因5'旁侧-nt.325~-nt.207之间119bp片段中，发现有两个类似的SP1反应元件及一个与半个维甲酸受体结合的模块，而CK13基因5'旁侧-nt.206~-nt.94之间113bp片段中-nt.199~-nt.192间的碱基CTGAATCA类似AP1/cAMP的反应元件。

In the first paper, magnet-lab biologists Michael Davidson and Kristen Hazelwood worked with researchers from the University of Alberta to create two new fluorescent-protein biosensors, molecular "beacons" that can tell if there is activity within a cell.

在第一份文件，磁体实验室的生物学家迈克尔戴维森和克里斯汀 hazelwood工作与研究人员从艾伯塔大学，以创建两个新荧光蛋白的生物传感器，分子"信标"它可以告诉，如果有活动的一间囚室。

My mother, two sisters and I went to Huntsville, the closest town

The result shows that particle swarm optimization performs better in this case, which implies that the two methods traverse the problem hyperspace differently.

优化结果说明在这个例子中粒子群优化有更好的表现，这也说明两种方法在问题的多维空间中搜索最优解的方式不同。

This thesis carries on research to a class of nonlinear Schrodinger Equation with wave operator of initial value periodic problem.

本文针对一维带波动算子的Schrodinger方程周期初值问题进行数值研究，对上述方程首先构造了守恒的半离散格式，然后将p次Hermite插值方法与有限差分方法相结合构造了差分正交样条配置格式，并证明这两个格式均为稳定和收敛的格式。

From the Maxwell equation in EMT sensing subsystem, two kinds of 3D electromagnetic integral solutions are obtained under material field distribution and with Dyadic Green function as integral kernel.

从EMT传感子系统的Maxwell方程出发，得到了两类物场分布情况下的以并矢格林函数为积分核的三维电磁积分解。
