查询词典 sample case

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~.

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。
