The determination of amino acids in blood clam antianaemia oral liquid using HPLC-AccQ-Tag method is reported. The oral liquid reacted with 6-aminoquinolyl-N-hydroxysuccini-mdyl carbamate. Then, the corresponding derivatives were analyzed with an HPLC. The chromatographic conditions were AccQ-TagTM C18 column for amino acids analysis (3.9mm×15cm); mobile phase of program elution sodium acetate solution(pH5.02), acetonitrile, Milli-Q water. The amino acids'AQC deriatives were detected at 248nm with a UV-detector. Eighteen kinds of amino acids were completely determined in 35 minutes.

以6-氨基喹啉-N-羟基琥珀酰亚胺基氨基甲酸酯为衍生剂，与毛蚶抗贫血口服液中的氨基酸柱前定量衍生，用WatersHPLC仪，AccQ-TagTM专用C18柱(3.9mm×15cm)，以140mmol·L-1的醋酸钠溶液(pH5.02)为溶剂A，乙腈为溶剂B，超纯水为溶剂C，进行梯度洗脱，检测波长为248nm，35min测试完毕。

Should use neutral cleaning solvent and then wipe dry with cotton twist mop cloth, cut Do not use acids, solvents or alkaline organic solvents such as gasoline scrub.

应使用中性清洁溶剂擦拭后再用拧干的棉拖把擦拭，切勿使用酸、碱性溶剂或汽油等有机溶剂擦洗。

By analyzing the composition of the feed and the specification of the product, a new process for the recycle of hexane and cyclo- hexane solvent of SBS plant in Yanshan PCGC is proposed.

通过对橡胶厂SBS车间溶剂回收工段进料及产品要求的分析，提出了己烷溶剂回收采用一塔流程的设计观点；经采用AspenPlus进行模拟，确定了一塔流程的可行性；并对目前的溶剂精制塔进行了核算，提出了目前两塔流程改为一塔流程操作的可能

In addition, you can set different solvents of normal boiling point, so that when heated evaporation, glue on the surface of high-boiling solvent retained for long time, does not make the surface coating on crusts, but to ensure that the amount of residual solvents, stinkof, does not exist.

另外，可将不同沸点的溶剂混合起来使用，这样在受热蒸发时，胶层表面的高沸点溶剂保留较长时间，不会使表面膜层结皮，但要保证残留溶剂量符合要求，不存在臭味、异味问题。

The results showed that using mixture could promote the conversion of rice straw below 50%, and inhibit the formation of low-boiling point materials.

结果表明，使用体积配比（有机溶剂占混合溶剂的体积比）小于50%的混合溶剂能够提高稻草的液化转化率，并且能够抑制低沸点挥发物质的产生。

Structural differences among the three gelators are only in the varied amount of methyl groups on the benzene ring.

从分子结构的差异、亲溶剂作用、分子几何构型、相转变热焓以及溶剂极性等方面研究了三种亚苄基山梨醇衍生物凝胶剂在有机溶剂中的自组装和凝胶化机理。

Information from other methods may be necessary, because some solvates are known to be stable at temperatures above the boiling point of the solvent.

3，溶剂化物 Solvation ，溶剂化物制造和储存原料药的条件可能会导致离析或形成溶剂化物或水化的原料药。

And in contrary, aniline has the intensive association tendency. Thisbehavior is believed to some degree to be related to the nature of solvated segments.

但仍可看到含氯的溶剂(1，2－二氯乙烷和氯仿)以及丁酮的〓较低，而含氮的溶剂的〓则较高，可认为它在一定程度上反映了溶剂化链段的特性。

The millimetersized tubular crystal selenium was first prepared. By studying the process of treating selenium in ethylenediamine, we proposed the mechanism of the preparation of selenides under solvothermal condition. The selenides came into being from the reaction of metal ions with Se〓, which was obtained by the amine attacking selenium. Moreover, a new precursor to prepare nanocrystalline selenides at room temperature was obtained. From this precursor, we have prepared nanocrystalline silver selenides, copper selenides, lead selenides and cadmium selenides nanorods.

首次报道了采用溶剂热处理的方法制备出厘米尺度的管状结构硒晶体；通过对硒粉在乙二胺中的溶剂热研究，初步探讨了以单质硒为硒源的溶剂热合成硒化物的反应机理应是硒受胺类的亲核进攻变成Se〓而进一步形成相应的硒化物；获得了合成硒化物纳米晶的前驱物，并在室温条件下合成了硒化银、硒化铜、硒化铅纳米晶和硒化镉纳米棒等。

Properties: Completely dissolved in solvent such as coal tar system, esters, turpentine and plant oil.

性能：在煤焦系，酯类溶剂﹑节油﹑物油中完全溶解，不溶于醇类溶剂，在石油系溶剂中部分溶解。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
