本文用X-射线荧光光谱分析法对麦饭石中的主元素和微量元素进行了测定，测定结果达到检出线的有24种，其中有些是人体所必需的元素。

In the experiment, it proved that the repetitiveness、 reproducibility、 comparability of the 2.0%(NH_4)_ 2CO_3 was better than the original method through repeated experiments. The result of it was equal to the sum of water soluble sodium and the exchangeable sodium and it had better precision and accuracy. The 2.0%(NH_4)_2CO_3 could be chosen as the probational measurement of total alkality.

在本试验中，通过多批次的重复试验证明，2.0%(NH_4)_2CO_3法的重复性、再现性、可比性良好，测定结果稳定可靠，在数值上等于水溶性钠与交换性钠的总和，而且有较好的精密度和准确度，可以作为测定总碱度的试用方法。

The linear relationship to detect methanol was not effected by a few amount of ethanol, acetone and propanol etc.

乙醇、丙酮和丙醇等干扰物不影响测定的线性关系，特别对水的交叉敏感相当低，可以在真实的大气条件下测定甲醇的含量。

The sample was isolated by sephadex G-25 gel filtration column after concentration. Then bioactivity was assayed by Candida albicans. The chemical components were isolated and identified by GC-MS. GC determined the relative percentage content of the extract, nine kinds of components were separated, identified and accounted for about 82.12%, the major compound was propenyl methyl disulfide.

浓缩后的样品通过Sephadex G-25凝胶柱分离提纯其中的有效成分，以白色念球菌进行生物活性测定，并用气相色谱-质谱法对其化学成分进行分离鉴定，GC法测定各种化合物的相对百分含量，共鉴定了9种成分，约占总提取物的82.12％，其中，主要物质是甲基丙烯基二硫化物。

The non linear regression applied to relation of the proton change number of acid with the proton concentration may improve the precision of pKa determination.

它首先牵涉到有机酸在溶剂中的电离形式[1]，然后是电离平衡常数中活度系数的测定[2]，再者是非水质子溶剂或有机-水溶液中质子浓度的精确测定。

Zincprotoporphyrin content in blood was detected with a hematofluorometer and compared with free erythrocyte protoporphyrin determined by extraction method in 30 pediatric patients.

作者用血液荧光仪直接测定了30例小儿微量血中锌原叶琳含量，并与萃取法测定的红细胞内游离原卟啉水平进行了比较。

Induced activation of Rac1,Cdc42 signal transduction pathway, monitoring the transfer of living cells activated sheet pseudopodium emerged and filopodia obvious morphological changes,such as measured values or fluorescence imaging of fluorescence intensity over time to continuously reduce until almost see the determination or observation.

诱导激活的Rac1、Cdc42信号转导通路，监测到转染激活的活细胞中出现片状伪足和丝状伪足等明显的形态变化，测定荧光值或者成像的荧光强度随着时间推移不断降低，直至几乎测定或观察不到。

There was no report, up to date, on the determination of flavonoids in Psoralea corylifolia L.. In this study, an HPLC method for simultaneous determination of corylin and bavachin was set up.

由于补骨脂中黄酮类化合物的分析测定未见报道，因此，本研究首次建立了同时测定补骨脂中补骨脂异黄酮和补骨脂二氢黄酮的HPLC分析方法。

Two pre-mixed pH dependent coating materials which have come into the market were choosen ,both made it.In quality evaluation,determined the disintegration latitude of product,established TLC of Psoralea corylifolia L.,.

在质量评价中，进行制剂崩解时限的测定，建立了补骨脂、肉豆蔻、吴茱萸的薄层鉴别以及补骨脂中补骨脂素、异补骨脂素的含量测定方法；并进行了制剂初步稳定性实验研究。

Methods 112 blood samples of occupationally lead-exposed workers were selected from a puddling factory in the suburb of Chengdu. An assay based on the polymerase chain reaction-restriction fragment length polymorphism technique of restriction enzyme Bsm Ⅰ was used to detect at the same time.

整群抽取成都市郊区某炼铁厂接铅作业人员112人，抽取其静脉血进行血铅、血清钙和基因多态性测定，按基因型测定结果分组分别比较其血铅、血清钙的差异，并进行血铅和血清钙的相关性分析。

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.
