The aliquot was determined and confirmed by gas chromatography-negative chemical ionization mass spectrometry using external standard method.

样品中三唑醇残留物由正己烷饱和的乙腈(含1%冰醋酸)提取，加入无水硫酸镁与无水醋酸钠振荡促使提取液分层后进行固相分散萃取净化，用气相色谱-负化学离子源质谱法进行测定与确证，外标法定量。

Soap is easy to combine with the ion of calcium and magnesium in alkalescency condition. The water insoluble lime soaps which deposit on the skin and may block the pores, cause skin irritation and skin hyper susceptibility.

而皂基皂不可避免的会与水中钙离子，镁离子在碱性环境下形成不能溶解的皂垢，很容易沉积在皮肤上，可能阻塞毛孔，引起皮肤的刺激，引发皮肤过敏。

We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

Purple teeth are red-based Ukrainian almandine; red-based, there are rose-colored, concentrated red, black and red of the pyrope; a green, yellow, yellow, and green, green in grossular; a green uvarovite so.

牙齿红紫色的乌克兰铁铝榴石，红色的，有玫瑰色，集中红色，黑色和红色的镁铝榴石，绿色，黄色，黄，绿，青（乌拉尔祖母绿的钙铝榴石）； 1绿色钙铬榴石等。

Objective: To investigate the influence of Trig, ALP and CO2 reagents on MTB automated analysis of magnesium in serum.

目的：研究在全自动分析仪上Trig、ALP、CO2等试剂对血清镁测定的影响。

We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium, by bombardment with alpha rays.

我们已经展示了人工放射现象的可能性，这种放射现象的特征是用以射线轰击用咄硼和镁中的正电子或负电子。

Magnesium aluminate spinel is a unique stable compound in MgO-Al2O3 system and well-known material due to its excellent properties. It has been widely used in various applications.

中文摘要：镁铝尖晶石是MgO-Al2O3系统中唯一稳定的二元化合物，是性能优良的耐火材料，广泛应用在各种领域。

Liquid diffusion technology was used to aluminize on the surface of AZ31 magnesium alloy.The hypereutectic aluminized coating was obtained.

采用液相扩渗技术在挤压态AZ31镁合金表面快速渗入铝，在合金表面获得过共晶渗层，并对渗层的成分、相组成、扩渗过程、纳米硬度和腐蚀性能进行分析。

And the improvement of this system that cationic colloidal magnesium aluminum hydroxide accompanied with the anionic microparticulate was discussed.

介绍了近年来微粒助留体系的研究进展，尤其是无机阳离子微粒助留体系，着重论述了阳离子氢氧化镁铝与阴离子聚合物的协同助留作用及其发展。

Objective To determine the compositions of magnesium aluminum hydroxide co-dried gel.

目的 确证氢氧化铝镁共干凝胶的组成。

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。
