采样

To minimize the estimated error, over-sampling or pre-conditioning filtering is commonly used.

对于传统的离散子波变换方法，初始分解系数与离散采样值不匹配是一个难点。

Point cloud models using discrete points as primitive element have many advantages such as data simple structure, compact space, and ability to express complicated surface in detail. However point cloud models usually can not be used directly.

点云模型以离散采样点为基元的几何模型，具有数据结构简单、存储空间紧凑，能够表达任意复杂表面细节，是造型所有表达方式中最自由的一种。

In visible spectral band, we measured the BHDF of grass and man-made object similar to grass with three angular sampling intervals in principal plane.

在可见光波段上，采取三种角度采样间隔，对草地及类草地的人工目标主平面的BRDF特性进行了野外测量实验。

For examples of usage, and how the formatting options affect the printing of numbers, look at Bob Keller's format sampler .

使用的例子，以及如何格式化选项影响到印刷的数字，看看鲍勃凯勒的格式采样。

In chapter 3, an honest tree is built upon prior logarithm normal distribution.

第二章提出了基于重采样技术的光谱特征选择方法，该法可找到包含某些子结构的特征信息，为质谱的分类和判别奠定了基础。

It inherits the advantage of PF, representing multiple uni-modal distribution instead of calculating probability distribution function explicitly.

该方法继承PF的优点，不需要直接求解概率分布函数，而是用随机采样得到的样本集合来表示机器人的位姿信度分布及其不确定性。

Aiming at complicated computing and difficulty of being realized when extending single sensor PHD filtering to the multi-sensor case by means of probability generating function, a multi-sensor multi-target sequential particle-PHD tracking algorithm is proposed based on the thought of sequential filtering for a centralized fusion system. The algorithm chooses the importance density function with regard to every sensor, and updates sample particle of every sensor layer by layer.

当采用概率母函数将单传感器PHD滤波推广到多传感器情形时，针对计算繁琐，难于实现的问题，本文基于集中式融合系统的有序滤波思想，提出多传感器、多目标有序粒子PHD跟踪算法，该算法通过选取与各传感器相关的重要性密度函数，层层更新各传感器的采样粒子，达到多传感器多目标有序PHD跟踪。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
