查询词典 weighted sampling

Inverse Distance Weighted method is sensitive to the distance and circle distributions are found around sampling point. IDW is an accurate interpolation method in case of the field information diffused from some center points.

距离反比法插值对距离比较敏感，出现很多以采样点为中心的圆形分布，在以点为中心呈扩散状分布的农田信息，采用距离反比法具有较好的插值效果。

This paper integrated the experts' judgments with grids as the sampling strategy in an abandoned pesticide plant in northern China, and applied a geostatistical method, inverse distance weighted interpolation, to simulate the pollutants- and risk spatial distribution.

本文以北方某废弃农药厂为例，结合专家判定采样法与网格采样法，采用地统计学方法中的反距离加权空间插值法，分两种情形将大于土壤环境基准值的区域划定为治理范围。

In order to solve this problem, a new algorithm for multivariate calibration is developed by combining optimized sampling and partial least squares, where the original training samples are non-negatively weighted and the complexity and predictivity of the model are considered simutaneously.

传统的多元校正模型大多根据经验方法选择代表性样品，在某些不利的情况下可能会影响校正模型对新样品的预测性能。

By means of uniform orthogonal sampling, we represent the shape signature of each model as a statistical distribution of its surface normals weighted by view-dependent depth. The distribution is further processed by spherical harmonics analysis to construct the final representation. By calculating the distance between shape descriptors of individual 3D models, a faithful similarity measurement is achieved.

算法从规一化处理后的物体形状出发，计算视点相关的深度加权的物体表面法向统计分布，并对该分布实行球面调和分析，得到深度加权法向映射特征，进而利用特征之间的距离度量任意三维模型之间的相似性。

Its main characteristics are on-line processing, slip weighted average sampling followed by linear fitting, and automatic correcting of K values.

其主要特点是在网上处理，防滑加权平均抽样其次是线性拟合，和K值自动纠正。

Through analyzing weighted method of image network sampling and statistic matching method of image network parameters, network analytical correction system of saline mud log has been compiled.

本文分析了图像网络采样加权算法及图像网络参数控制的统计拟合分析方法，编制了盐水泥浆测井资料的网络分析校正系统。

Further improvements can be obtained by properly distributing different weighted coefficients aq on sampling points both for the pass band and stop band.

通过为每一个频率采样点设置一个权重系数，并根据计算出的，判断在通带和阻带内哪个取样点的误差最大，适当地调整权重系数，我们就发展出了基于RBF的FIR滤波器优化设计算法。

TWA is 8h time weighted average density, the sampling examination time more approaches 8h, the examination result accurately is real.

TWA是8h的时间加权平均浓度，采样检测时间越接近 8h，检测结果越准确真实。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
