查询词典 sample box

The essay reviews previous study on this topic and A-share listed firms that have periodically rotated auditors during the period form 2003 to 2005 will be selected as research sample. Basing on whether or not the listed firm changes the accounting firm, the sample will be classified into two group—internal auditor rotation group and external auditor group.

本文在回顾国内外重要文献的基础上，选取2003-2005年进行审计师定期轮换的A股上市公司作为研究样本，并将其按是否同时变更会计师事务所分为内部轮换和外部轮换两类，使用调整后的截面Jones模型估计的操纵性应计利润绝对值计量盈余质量，并将其作为审计质量的衡量指标，对定期轮换与审计质量之间的关系进行了实证检验以分析定期轮换制度的实施对审计质量的影响。

We detected Fibrobacteres in the rumen sample (3.33%) but not in the enriched sample.

在水牛瘤胃内容物中，丝状杆菌占3.33%，但在富集培养物中未被检测到。

Sample and Hold Circuit The sample and hold circuit is used to take a narrow-band measurement of a time-changing signal and to hold that measured value until reset.

To reduce the area of the layout,we use one-stage OP-AMP in the ROIC,and the sample and hold circuit shared by pixels in a column is also applied instead of sample and hold circuit in every pixel.

本设计采用电容反馈互阻抗放大器结构作为输入级，列共用方式的采样保持电路，源级跟随器作为输出级，用移位寄存器来控制行、列选通并控制电路工作的时序。

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits. The preceding eight stages are 1.5bits/stage, and the last stage consists of two comparators. Every input sample is converted into 18 bits binary signals, and these binary signals are converted into 10 bits binary signals through digital correction circuit.

模数转换电路采用流水线式的结构，包括具有单端输入/差动输出功能的采样保持电路和九级的子电路，前八级子电路使用1.5位/级的结构，最后一级使用两个比较器实现，每个输入值被转换为18位的二进制代码，通过数字纠正技术最终实现10位的输出，按照前端电路的应用要求，这个模数转换器实现1.33MHz的采样速率。

微密度仪测定的结果为光密度，需对其进行标定，标定结果表明：在样品厚度一定时

Focusing on the computational bottleneck of traditional CCA,StreamCCA introduces a low-rank approximation technique to reduce the dimensionality of product matrix resulted from sample correlation matrix and sample variance matrix,which improves computational performance efficiently on the premise of holding approximate precision.

经理论分析和实验证明，S treamCCA能够在线精确地识别两条多维数据流的相关关系，可以作为通用的预报和诊断分析工具广泛应用于数据流挖掘领域。

Based on the previous fault possibility distribution kept within the sample mean and covariance matrix with forgetting factors,a strategy for constructing the target output of the new training sample set was ...

该算法通过带有遗忘因子的样本均值和样本协方差矩阵保存样本所包含的故障可能性分布信息，并在此基础上产生新增样本的目标输出，用于训练FBF网络，以实现故障分类边界的在线跟踪。

For these important and practical problems,sample covariance matrix is an important statistic because many important statistics are functionals of it.When we make statistical inferences,such as estimations and/or hypothesis tests,the sample covariance matrices must be investigated.

以上诸多方面在做估计和假设检验过程中，无不用到大维随机矩阵的处理，尤其是大维样本协方差矩阵的相关性质，因为多元分析中许多重要的统计量都可以表示成样本协方差矩阵的函数。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination

中国人的传统美德是谦虚谨慎，对别人的恭维和夸奖应是推辞。如
