所以，上光产品的制卡和会员卡制作油墨应选用耐酸类、酯类溶剂和耐酸碱性的。

Experiments show that the hollow fiber membrane is provided with high-temperature resistant, solvent resistance, acidproof and alkaliproof, and antioxidant performances.

实验证明：该类中空纤维超具有耐高温、耐溶剂、耐酸碱、耐氧化的性能。

The heat of dilution of LiCl/n-C3H7OH-H2O solution has been measured with LKB 2107 flow microcalorimeter-PC data acquisitor system at 288.15K,298.15K and

使用LKB2107型微量热计-微机数据采集系统测量了288.15K、298.15K、308.15K下LiCl/-n-C3H7OH-H2O体系在不同混合溶剂浓度下的稀释热。

The method has been used to determine Phthalic esters in drinking water and seawater sample. 3. Single drop microextraction, followed by gas chromatography with flame ionization detection has been applied to determine Formaldehyde, Acetaldehyde and Acraldehyde in water based on 2,4-Dinitrophenylhydrazine derivatization. Extraction solvent, extraction time and stirrer speed were optimized. Optimal experimental conditions were as follows: 1.6μL toluene microdrop exposed for 30 min in a 3ml aqueous sample placed in 4ml vial and stirred at 600 rpm/min.

以2，4-二硝基苯肼衍生，单滴液相微萃取与气相色谱火焰光度检测器联用测定水样中的甲醛、乙醛、丙烯醛，考察了萃取溶剂、液滴大小、萃取时间、搅拌速度、盐效应等对该方法的影响，并对影响液相微萃取的各种因素进行了系统的阐述，确定了该体系的最佳实验条件，实现了甲醛、乙醛、丙烯醛的提取和富集。

I.e. once cured an addition cured compound can be exposed to any of the above materials with no effect.

这种不固化的现象存在于加成固化中，在缩合固化中没有，相反情况也是这样的，一旦加成固化后，则不受上述任何材料的影响，但将其长期浸泡在某些溶剂使其膨胀，就会受到影响。

In addition, the reaction mechanism and growth mechanism in this solvothermal process are analyzed.

同时，对这个溶剂热过程中的反应机制和生长机制进行了分析。

In addition, the mechanism of reaction and the selection of the reagents have also been investigated.

最后，在充分考虑实验影响因素的情况下对以二乙烯三胺为主的混合溶剂热中晶体形貌形成的机理进行了初步探讨。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
