维数

The TTT Taxi Service in Tehran is required to deliver some magazines to N locations in Tehran.

这是一个动态规划的题目，这个题目我用的是三维数组保存状态的方法实现的。

In a flat model database, there is a two dimensional array of data.

在一个单位，模型库，有一个二维数组的数据。

These conditions do not relate to the unknown parameters but the dimension of model, so it is easy to apply in practice. Next, we consider the relative efficiency of LSE against the beast linear unbiased estimator.

我们给出了Pitman准则下，最小二乘估计优于Within估计的一个充分条件，最后又得到了广义均方误差意义下两步估计一致的优于Between估计和Within估计的充分条件，并且这些条件只是和模型维数有关而和未知参数无关的一些不等式关系，因此便于实际应用。

The results also revealed a tendency of decrease in the fractal dimension with the increase of floc size, which is resulted from the unproportionate growth between the floc size and the number of the primary particles contained in the flocs.

同时计算结果表明，絮凝体的分形维数有随其粒径增大而逐渐降低的趋势，其原因是絮凝体的成长粒径与絮凝体中所包含的初始颗粒增长速度不成比例。

Because vector overloads operator , you can use the notation as if you were using a built-in two-dimensional array

因为容器重载了操作符，所以你可以用来操作就如同使用内置的二维数组。

The narrowband interference suppression can be realized by tracking the interference subspace and projecting the received signal vector to the orthogonal subspace of it.

文中采用RRLS算法跟踪干扰子空间，并根据干扰子空间最小特征值与噪声功率的比值自动确定干扰子空间的维数。

The Karhunen-Loeve transform is used for feature reduction of the feature vectors and creating the subspaces. Then the distance between unknown-classification feature vector and each subspace is calculated to determine the class to which the vector belongs.

通过K-L变换，能有效降低特征空间的维数，形成各类别对应的特征子空间，然后分别计算待分类模式与各子空间的距离实现模式分类。

By the truth that both coronary artery disease patients and diabetic patients had the turbulence of vegetal nerve system.

选用的指标是散点图几项量化指标、测度熵和关联维数。

It avoids the internal resonance phenomenon, and smaller dimensions of the impedance matrix are obtained by comparison with the volume integral equation.

推导一种用于求解介质体散射问题的面积分方程，它克服了内谐振现象，且同体积分方程相比，获得了更小的阻抗矩阵维数。

According to seismic wave dynamic mechanics,the reasonable nonlinear mapping relationship between seismic records and log data was established.

摘要根据地震波动力学，建立了地震记录和测井数据间的合理的非线性映射关系，通过获取地震记录的自回归系数、分形维数、最大Lyapunov指数和突变参数，得到了声波时差和地层密度测井曲线，建立了地层弹性参数、强度参数的获取方法。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
