The sugar composition of the membrane was carried out by hydrolyzing 5 mg of the membrane in sealed ampules by either 2 M HCl or trifluoroacetic acid at 100 °C for 5, 10, and 15 hr and then the dried hydrolysate was analyzed by thin layer chromatography as well as high performance liquid chromatography.

将此薄膜取5 mg分别加入2 M盐酸或三氟醋酸置入安培瓶并熔封，於100 ℃下作用5、10、15小时将醣类水解，再将水解之产物以薄层液相色层分析法与高效能液相色层分析仪分析。

No differences in transparency, pH change or quanty of meperidine were observed either in accelerated tests at 40℃ or storage test for six months. Nevertheless, a decrease in pH value without significant changes of transparency and meperidine content was observed in accelerated tests at 60℃ after storage for 15 weeks. The pH value and meperidine content decrease significantly in both types of ampules when subjected to accelerated tests at 80℃ for 15 weeks.

结果显示盐酸配西汀注射液在两种安瓿中经40℃加速试验与储存六个月样品之外观、透光率、pH值和含量均未呈明显变化；加速试验60℃者於15周开始pH值有明显下降，此外，外观、透光率与含量均未呈明显变化；而加速试验80℃者於15周之外观与透光率虽未呈明显变化，但其含量与pH值均明显下降，表示有分解反应发生。

Esterification with some inorganic acid chlorides and anhydrides has been studied too, but with limited success only due to rather violent side reactions and an early precipitation of the reaction products.

同时也做过用无机盐酸及酸酐酯化的研究，但是只取得了有限的成功，只是因为相对剧烈的副反应及反应产物过早的沉淀。toommy：感谢参与，继续努力！亚太币+ 30 贡献+ 2

The quality of dispersive ta blets was able to be controlled .Conclusion: The prescription was reasonable,the dispersive tablets were

可以控制。结论筛选处方合理，制备的盐酸小檗胺分散片崩解快，分散均匀性好，溶出快而完全。

Treatment of the diacetoxy-calix [4] arene with a series of ditosylates in dry MeCN in the presence of NaOH resulted in formation of electron-rich calix [4] areneocrowns, which reacted with 4, 4'-bipyrindinium and p-bis -benzene at room temperature in dry MeCN to afford self-assembling [2] catenanes by π-π stacking interaction.

以杯[4]芳烃为原料，通过三氟乙酸铊将其氧化成醌，醌类化合物在Zn粉、冰醋酸、少量盐酸和过量的乙酸酐中反应得到双乙酰化产物，利用氢氧化钠使其水解，然后再与各种对甲苯磺酸二酯进行环化反应，得到一系列具有富电子空腔的杯[4]芳烃并冠醚。

The corrosion characteristics in water, 5% HCl solution and 5% HNO3 solution of the coatings on 45 steel cladded by electrospark deposition with Cr, W, Mo and Ni anode was studied.

对正火45钢基体上的Cr、W、Mo和Ni电极电火花熔涂层在水、5vol%盐酸及硝酸水溶液中的腐蚀行为进行了研究。

The two groups were treated, respectively with trazodone hydrochloride or clonazepam for 21 days.

试验组用盐酸曲唑酮片(最大剂量≤400mg.d-1)，对照组用氯硝西泮片(最大剂量≤4mg.d-1)治疗21d。

Procaine hydrochloride, ampicillin sodium and dapsone can react with 1,2-naphthoquinone-4-sulfonic acid to form salmon pink compound, respectively. Their maximum absorption wavelengtb.es were shifted from the range of ultraviolet to the visible light.

利用分光光度法研究了抗生素类药物氨苄西林钠，抗麻风病药物氨苯砜，局部麻醉药盐酸普鲁卡因与1，2—萘醌—4—磺酸钠的显色反应，建立了灵敏简便的分光光度法。

Any glassware to be used with the reagents should be thoroughly washed with 2M hydrochloric acid and then rinsed with distilled water or high quality deionised water.

与试剂一起使用的玻璃器皿应当用2M 盐酸充分洗涤，然后用蒸馏水或高质量的去离子水漂洗。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
