插补

In chapter 4, a family of two-parameter operators on Abelian group is introduced and its interpolation theorem for approximation is established.

所得的结果包含了R.DeVore定理作为特款，还包含了算子逼近的插补定理，是非线性逼近方面的一项基础性工作。

The conventional linear and circular interpolation in Cartesian coordinates were supplemented by polar coordinates and helical interpolation.

传统的笛卡尔的线形和环形内插法结合被极坐标和螺旋插补所补充。

In this paper, we analyse the features of bicircular arc interpolation algorithm which isoften used in numerical control manufacturing.

本文在分析数控插补最常用的双圆弧插值算法特点的基础上，将以局部坐标系中的三角运算为核心的传统双圆弧插值算法，改造成为以整体坐标系中的线性运算为核心的矢量形式的双圆弧插值算法，从而减少了计算的复杂性和程序的复杂性，提高了效率和可靠性。

Later, using the method of project transform to set up the models of trapezia distortion and torsion distortion, and interpolate the gray-level of rectified image with bilinear interpolation.

然后利用投影变换的方法建立了梯形失真和扭转失真的校正模型，并应用双线性插值算法对校正的图像进行灰度级插补。

The method has extended the image unwarping capability of the existing methods for SVP omni-cameras to tolerate lens/mirror assembly imprecision, which is difficult to overcome in most real applications. A new method called "edge-preserving 8-directional two-layered weighting interpolation" is proposed for interpolating unfilled pixels in a perspective-view or panoramic image resulting from unwarping an omni-image taken by a non-SVP omni-camera.

b 提出一个称为&双层八方向之边缘保存权重式插补(edge-preserving 8-directional two-layered weighting interpolation)&方法，可用以插补从一个非单一视点之全方位摄影机摄取之全方位影像转正到透视(perspective-view)或环场影像之未填充像点。

As sophisticated calculation of the transformation is hard to implement in each sampling time of NC machining,the coordinated motion of NC coordinate axes is expressed as quintic parametric spline function s,which use the rotation angle of the work gear as the parameter,and the re.

由于在数控加工每个插补周期中难以实现这种涉及大量运算的运动转换，因此将数控坐标轴的展成运动表示为以工件齿轮转角为参数的五次参数样条函数，保证了插补的实时性和精确性。

It identifies "worse condition points" along the path according to the curve information, machine tools capability and machining requirement. Integrated with adaptive interpolation, segmented high speed machining is adopted. Different constant speed segments and speed transition segments are obtained according to the feed motion constraint model, and the corresponding feed information are stored in a penta-element lookup chain table. By referring to the lookup table, the interpolator can automatically determine the feed motion.

算法根据加工路径的曲线信息、机床加工能力及加工要求确定&最差状态点&，并结合自适应插补思想，采用分段高速加工，根据进给约束模型得到不同恒定速度加工段及速度过渡段，并将这些信息存储在一个五元的自适应Lookup链表中，插补过程中通过查找该链表确定进给参数。

But when a rectangular continuous data set appears to have a longer tailed than normal distribution or it contains some values that are influential on statistical inference with normal distribution, the multivariate t distribution becomes useful for multiple imputations as an alternative to the multivariate normal distribution.

在多重插补法的基础上，当一个矩形连续数据集看起来有一个比正态分布还长的尾巴，或者是它包含了一些对正态分布的统计推断有影响的数据，多元t分布作为多元正态分布的替代分布，对于多重插补来说变的很有用了。

Means no interpolation, 1 means interpolate always, 2means interpolate only for secondary rays (that is, no interpolation for eyerays and interpolation for reflections, retractions, and so forth).

0表示没有插补， 1手段插值一如既往， 2手段只有次级插值射线（即，不对直接光线差值，但对反射、折射差值，等等）。

After the transformation design , the economy numerical control machine has the localization , the straight line inserts , inserts along the counter circular arc , function suspension ,circulation processing , male inch thread processing and so on .

设计改造后的经济型数控机床具有定位、直线插补、顺逆圆弧插补、暂停、循环加工、公英制螺纹加工等功能，且加工质量稳定可靠。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
