采样

The results show that bandpass signals can be represented correctly with undersampling.

从实际的采样波形可以看出：欠采样完全可以反映出这些信号的特性。

The asymptotic covariances of different unbiased estimates are derived, which can be used for the comparison of different measurement methods and various estimations.

在连续系统离散时域模型辩识中，论文分析了采样频率对辨识精度的影响，给出了采样频率选取的经验公式。

Focal-animal and continuous sampling schemes were employed to observe the captive porpoise colony consisting of 3 to 6 individuals in Wuhan Baiji Dolphinarium from 2000 to 2002, and a total of 136 hr of behavioral data was recorded.

采用焦点和连续采样法，于2000-2002 年连续观察了武汉白鱀豚馆的江豚群体(3-6 头)，累计采样时间超过136hr。

Finally, an FIR decimation filter used in 14bit 1. 5625MHz Nyquist rate oversampled ADC is designed.

最后设计了一个用于14bit 1.5625MHz Nyquist率过采样ADC中的FIR降采样滤波器。

The constraints of oversampled cosine modulated filter banks with perfect reconstruction are deduced in this paper and then we propose an iterative method for designing the prototype filter.

接下来我们推导了过采样余弦调制滤波器组的完全重构条件，提出了一种迭代算法设计完全重构的过采样余弦调制滤波器组。

The results show that under the different sampling conditions, the detection finds different nonlinearity of chaotic time series. Especially for the oversampling time series, there can often be some illusive results.

研究发现，在不同的采样情况下，混沌时间序列的非线性特性检验有所差异，尤其对于过采样时间序列，往往会出现虚假的判断结果。

Bull; FG is an interpolated technique. This means that the indirect lighting is sub-sampled (calculated less than for every pixel) and the values between those are interpolated. However, if you are doing an animation, and the result between two frames are slightly different, this may hypothetically cause not one pixel to change, but a large area of pixels to change (i.e. all pixels influenced by the interpolation of that FG point).

bull； FG是一个以内差值替换计算的技术，这意味着非直线的漫反射光线被二次采样，（根据其少于每个像素的值计算），然后从中选出基于两个数中间的值被选为插值，然而，如果你是在制作一部动画，那么前后两帧之间的结果是明显不同的，这可能——假设——不仅仅导致一个像素的改变，而是一整块区域像素的改变（也就是说，所有的像素都受那个FG采样点的插值的影响）。

In the preprocessing phase, our algorithm samples the environment in a 3D lattice structure, the potentially visible surface list of square-frustum at each cell in the lattice are precomputed and stored in a cube at the center of the cell.

当视点不位于场景采样点处时，从该视点邻近的采样点处存储的可能可见的多边形表中搜索那些位于当前视域内的多边形，只需绘制这些多边形即可。
