分光光度计

The metal sample is dissolved with HCl H 2O 2, and the dissolved nickel is separated from other activation products by anion exchange. Nickel is then complexed with pealetyldioxime in the alkaline solution, extracted with toluene, and finally determined by liquid scintillation counter.

先将样品用HCl H2 O2 溶液溶解、再经阴离子交换、氢氧化物沉淀分离后，在碱性溶液中用丁二酮肟配合镍、甲苯萃取、稀HCl反萃后再用液体闪烁计数器测定反萃液中6 3Ni放射性活度、原子吸收分光光度计测定金属中稳定镍。

We have measured trace iron ion in engine oil by spectrophotometry accurately, with the absorption wavelength locates at 430nm and under the color system of Fe－Ammonium Sulfate－Sulfosalicylic acid－Ammonia. The results show that the relative standard deviation of this sample is 5.5%.

以Fe－硫酸铵－磺基水杨酸－氨水为显色体系，用分光光度计，在430nm的波长下，准确的测定了发动机机油中的微量铁。

At that time, the measuring instruments called spectrophotometers had a rather limited sensitivity in the range of 43 dB/km.

那时，一种称为分光光度计的测试仪器灵敏度相当有限--在43 dB/km 左右。

These press scanning spectrophotometers are capable of producing a spectral data file that can be converted into a working profile.

扫描分光光度计的这些杂志报纸能够产生一笔光谱的数据能转换成工作描绘的文件。

The introduction of spectrophotometers equiped with micro cells and detectors capable of operating at a additional wavelengths has extend the scope of ultraviolet detection.

引入使用微池的分光光度计和可以在一个附加波长工作的检测器扩大了紫外检测的范围。

Density , color meters and spectrophotometers is the most commonly used color printing measurement instruments,Their color reproduction process control provided important information, But those portable device are expensive,and they do not have on-line testing functionality.

密度计、色度计和分光光度计是目前印刷中最常用的颜色测量仪器，它们在颜色复制的过程控制中提供了重要的信息，但这几种便携式测试仪，多为价格昂贵的进口专用设备，且不具备在线检测功能。

Degree of absorption along and perpendicular to the main optical axis was studied for some uniaxial minerals, using several types of spectrophotometers.

用几种分光光度计研究了一些一轴晶矿物平行和垂直于主光轴方向的吸收程度。

Because of the difficulties caused by absorption by oxygen and the low output of conventional spectrophotometers at this wavelength, measurements are more conveniently made at 205 nm, where the absorbance is about half that at 190 nm.

由于氧气吸收带来的困难和常规分光光度计在这个波长的低输出。205nm更常见地用于测量。这里的吸收大概只有190nm的一半。

If the food is a transparent liquid such as wine, beer, or grape juice, or if a colored extract can be obtained from the food, then various types of colorimeters or spectrophotometers can be used for color measurement.

如果食品是一种透明液体，或者如果可以从食品中获得有色提取物质，那么就可以用各种类型的比色计或分光光度计进行色泽的测定。

Sources include some biosafety cabinets, certain types of hand-held light sources, transilluminators, crosslinkers, and some laboratory instruments such as spectrophotometers.

来源包括一些生物安全柜，某些类型的手持式光源， transilluminators ，交联剂，以及一些实验室仪器，如分光光度计。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
