查询词典 sample case

Most of the AFMs scan sample under a stationary cantilever. These AFMs only can test small samples, because the size and weight of the sample is restricted by the size and resonance frequency of the tube piezoceramics scanner.

常见的原子力显微镜多采用样品扫描方式，因为样品尺寸和重量受到传统的管状压电陶瓷扫描器的限制，它只适合小样品的测试。

The interference method for determination of refractive index has many advantages, such as easy-producing sample, extensive testing range, and the reutilization of sample.

因此，不断的寻找新的测量方法来满足技术发展的需要，一直是光学测量的重要研究任务之一。

Riffle division method: a riffle is a kind of non-mechanical sample divider, which is usually fed manually. The sample is divided into 2 equal parts by riffle, with one retained and one rejected.

二分器缩分法：二分器系非机械式样品缩分器，通常用手工给料，样品通过二分器被分成二等份，一份保留，另一份弃去。

The surface morphology was studied by the AFM also.Though the average size of grain and the RMS(root-mean-square) value of the two samples is diffe-rent,comparing sample A with B, the result shows that sample A is more smooth.

通过原子力显微镜，对生长在两种衬底上薄膜的表面形貌做了观察，其晶粒的大小与表面粗糙度有一定的差别，表明二者都是以柱状形式生长的。

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.

采样保持电路采样保持电路，是用一个窄波段测量时间变化的信号，并认为测值，直至复位。

Sample and Hold circuit; Sample-switch; Operational Amplifier; Charge Injection

采样保持电路；采样开关；运算放大器；电荷注入

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。

Don not attempt to do something which you can not to do.

不要企图做那些办不到的事情。

The expression of CTGF and TNF-αweredetected by immunochemistry and the number of Clara Cells was calculated.

光镜下观察肺组织的病理变化，采用免疫组化染色观察肺组织中结缔组织生长因子和肿瘤坏死因子-α的表达和Clara细胞的数量。
