Results: The absorbance of plumbum presented a linear relationship in the range of 2.0-20.0 ng/ml (r=0.998 4), with the average recovery of 97.48%, RSD was 2.51%.

结果：铅元素在2.0～20.0 ng/ml范围内其吸光度与浓度呈良好的线性关系（r=0.998 4），平均回收率为97.48%，RSD=2.51％。

While looking in the polar axis scope, adjust the diopter adjustment ring to focus on the reticle in the field of view.

当观察极轴镜时，调节曲光度调节环使视场中的划分板对焦。

Boiling points should be identical. Hence, the only difference in properties one should observe for the two carvones are the odors and the signs of rotation in a polarimeter.

因此，它们在性质上的唯一区别应该可通过观测两种香芹酮的气味和旋光仪中旋光度的符号而得知。

The difference of the data obtained by polarimetry and acid-base titrations was not significant.

旋光度法简便、快速、准确，可用于盐酸麻黄碱滴鼻液的含量测定。

Methods Ephedrine hydrochloride nasal drops was quantified by polarimetry and acid-base titrations. The data were analyzed by t-test.

分别用旋光度法与酸碱滴定法测定盐酸麻黄碱滴鼻液的含量，并将其结果进行比较。

Methods Ephedrine hydrochloride nasal drops was quantified by polarimetry and acid-base titrations.

分别用旋光度法与酸碱滴定法测定盐酸麻黄碱滴鼻液的含量，并将其结果进行比较。

During the course of the experiment, the student will be exposed to fractional distillation under vacuum, gas chromatography, refractometry, polarimetry, and IR absorption spectroscopy.

气相色层分析，折光率的测定，旋光度的测定和红外吸收光谱。

Objective To determinate the content of ephedrine hydrochloride nasal drops by polarimetry instead of acid-base titrations.

；！AaY M0 目的用旋光度法替代酸碱滴定法测定盐酸麻黄碱滴鼻液的含量。

Analytical procedures for the preparation of the filter used to Polarography, Spectrophotometric analysis and chromatographic analysis of the mutual interference components simultaneously.

利用编写的滤波解析程序，对极谱分析、分光光度分析以及色谱分析中互为干扰组分进行同时测定。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
