采样

Sampling is done in one of three ways: Entire Population, Random Sample, or Both .

采样是在做一个三种方式：全部人口，以随机抽样方式选出，或两者兼而有之。

I. method with input and output data filter is discussed. By means of a so called mearn-square root of random vector presented in the thesis, the convergence of the C.

考虑到许多计算机控制系统在数据采样时带有滤波器，我们还讨论了带输入输出数据滤波器的相关积分方法。

At first, this dissertation takes the natural gamma log as an example to put forward the regularized least-squared deconvolution theory, with which not only the effect of the surrounding formation is removed, but al so the effects of the well logging velocity, sampling interval, the ratemeter time constant, the detectorlength and the formation dip-angle are re moved.

首先，本文以自然伽马测井曲线为例，研究了正则化最小乘方反褶积方法。应用该方法，不仅消除围岩对自然伽马曲线读数的影响，而且消除测井速度、测井采样间隔和率表电路时间常数的影响。

Which is the sampling rate of raw data?

原如始数据的采样频率是多少？

The steps by the Rayleigh quotient method to obtain the optimal desampling FIR filter are also presented.

推导了信噪比增益与降采样滤波器权系数的关系，给出了采用 Rayleigh 商方法求解给出准则下最优FIR滤波器的方法和步骤。

The relation of the SNR and the coefficients of the filter adopted is deduced. The steps by the Rayleigh quotient method to obtain the optimal desampling FIR filter are also presented.

This recording first appeared in 1972 on the sampler album The New Age of Atlantic and was later included on the compilation album Yesterdays in 1975 and on the 2003 re-issue of their album Fragile.

此版本首次出现在1972年的采样专辑The New Age of Atlantic中，后又收录到1975年发行的专辑Yesterdays以及2003的重制专辑Fragile中。

The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.

本文所建立的预测方法模型是基于GIS矿产资源评价方法的经验模型法及找矿信息加权模型法的综合使用，对多源数据采用多种分析手段，先以研究区1：5万区域地质资料和矿产资料为基础，综合地球化学异常资料，通过Mapgis的空间检索与分析，做出全区成矿有利区分布图；而阿次夏热嘎南部地区离散的采样点的地球化学数据，是采用面向对象编程语言Dephi与GIS控件Mapobjects为开发工具，运用距离倒数插值法进行插值网格化，从而将离散的数据转换为栅格型数据，矿床定位分析、GIS空间迭加分析，预测出该地区成矿有利区。

Firstly, based on the developed vibration testing method, a method for monitoring abrasion fault on main bearing of reciprocating engine using noise measurement is presented.

在比较几种传统方法后，提出了采用高速数字信号处理器DSP电路和插值算法来进行噪声信号的时域同步平均处理。克服了基于锁相环电路采样方法跟踪精度低、速度慢和使用不便的缺点。

It also needs to save, analyze and redisplay these signals. But traditional measuring instruments can't satisfy these requirements already. Digital oscilloscopes have little storage, few channels and weak analytical ability.

然而，采用传统的测量仪器已经不能满足要求，如果采用数字存贮示波器记录数据，也存在着存储深度不够、采样路数太少和分析处理功能较弱等问题。

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。
