查询词典 sample

A sample and hold circuit (10,50) is arranged to operate in a plurality of states including at least one sample state and a hold state to sense the current flowing through the sense cells (4) when in the at least one sample state but not in the hold state.

取样保持电路(10，50)设置成在多个状态工作以在至少一个取样状态而不是保持状态读出流经读出单元(4)的电流，其中所述多个状态包括至少一个取样状态和保持状态。

Nevertheless, in many practical applications such as in low sample support or when the signal statistics are rapidly time-varying, we may not have enough sample to form the sample covariance matrix.

然而，常规的子空间估计方法由于涉及到阵列协方差矩阵的估计及其特征值分解，从而需要较高的计算复杂度。

For the case where the sample covariance matrix is unknown or the sample support is not sufficient to form the sample covariance matrix, we carry out the spatially smoothed CSA-MSWF to quickly find the signal subspace and the noise subspace.

如果阵列协方差矩阵是未知的，我们采用空间平滑的CSA-MSWF快速计算信号子空间和噪声子空间的基矢量。

The temporal effect is said to occur while sample molecules are passing a fixed-position detector. Since the sample dispersion keeps changing during the monitoring, the signal recorded should be different from that of the true sample distribution in the flow.

所谓时间效应是指样品在管路里流动时，由於在管中产生的分散现象，会导致样品在通过侦测器之时，样品的分布会因流动而改变，因此所测得样品之讯号和实际样品之分布并不相同。

Composition of the sample is random implies that the sample mean, the sample total... are random variables.

检讨公司在特定的销售区域中，可能扩展的程度，及研究各区域之相对市场的有利机会。

The procedure involves the generation of a second independent sample and a test that the estimates of the sample mean and standard deviation determined in the first sample are reliable estimates of the population mean and standard deviatio~.

涉及的程序产生的第二个独立的采样和测试的估计数的样本均值和标准差确定的第一个范例是可靠的估计的人口平均和标准偏差。

The popular method is to approximate the pattern of a sample by multiplying the size of the sample and the pattern of the unit sample.

国际上普遍认为：对不同大小的数据样点，不可能有统一的模板。

In chapter one,the writing research the questions in sample rotation when sample with simple random sampling according the process of the sample rotation.

第一章 这章内容属于文献综述性质的，主要是按样本轮换的实施过程，讲述前人对简单随机抽样下的样本轮换理论的有关问题。

Experimental result showed that under the wavelength of 460 nm,there was good linear relation between absorbency and content of SO42-;and stationary time that absorbency value needed became longer along with the increase of sample quantity of phosphoric acid.When absorbency become stationary,there is good linear relation between the phosphoric acid sample quantity and the content ofSO42-.So the content of SO42- can be adjusted by turning the sample quantity to make it in scope of standard curve.

实验结果表明，在波长为460 nm处，硫酸根含量与吸光度成良好的线性关系；随着磷酸取样量的增加，吸光度达到稳定值所需的时间相应增加，稳定后磷酸取样量与硫酸根含量成良好线性关系，因此实验过程中可通过调整磷酸的取样量来调节硫酸根含量，使之在标准曲线的测定范围内。

In chapter 4 based above two chapters, we disscuss sampling method of supplemented sample under both cluster sample and stratified sample having auxiliary information.

已有的 分层抽样和整群抽样方案都有自己的使用范围，在不适合的情况下使用效率很低。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
