The research indicates that:(1) detecting λmax (277nm) can identify Metronidazole Buccal Tablets prepared by Chongqing Medical College;(2) detecting λmax (321nm) and λmin (265nm) can identify Metronidazole Disodium Phosphate for Injection prepared by Chongqing Medical College;(3) detecting tr (6.7min) in HPLC-UV spectrum can identify Ceftriaxone Sodium for Injection prepared by Chongqing Keru Pharmacy Co.;(4) detecting tR (10.2min) 6.7min in HPLC-UV spectrum can identify Clarithromycin Tablets prepared by Harebin Yida Pharmacy Co.;(5) detecting λmax (254nm) can identify Potassium Sodium Dehydroandroan Drographolide Succinate prepared by Hong Kong Yaohen Co..

结果表明：①测定紫外最大吸收波长λ_(max277nm可鉴别重庆医科大学医药研究所制备的甲硝唑口颊片；②测定紫外最大吸收波长λ_(max321nm和最小吸收波长λ_(min265nm可鉴别重庆医科大学医药研究所制备的注射用甲硝唑磷酸二钠；③测定HPLC-UV中的保留时间(t_R6.7min)可鉴别重庆科瑞制药股份有限公司制备的注射用头孢曲松钠；④测定高效液相色谱的保留时间(t_R10.2min)可鉴别哈尔滨伊达制药厂提供的克拉霉素片；⑤测定紫外最大吸收波长(又max254nm)可鉴别香港耀恒公司提供的炎琉宁。

We think that studying is fundamental for us, that's why we keep dissenting, to continue to have the possibility to study and make research.

我们认为学习是我们的基础，这就是为什么我们保留意见，并极力保留学习和做研究的可能性。

Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

从胺基酸序列分析显示，竹嵌纹病毒复制酵素中间区域的类解螺旋酵素具有解螺旋酵素的保留性胺基酸区域，经实验显示此蛋白具有ATPase和RNA 5'-triphosphatase活性，而且是依赖镁离子进行反应的，其中保留性胺基酸的突变会破坏其催化能力，说明这在大肠杆菌表达的蛋白质经过变性及重新摺叠的过程，具有和其他SF 1解螺旋酵素相似的特性。

Finally, the effect of temperature on the retention behavior in AS20 column was studied and it was showed that the retention of nine compounds exhibited endothermic behavior.

温度对其保留行为的研究结果表明九种化合物的保留表现出了吸热效应。

2Examine the chromatograms of the solutions to be examined in the assay. The two principal peaks in the chromatogram obtained with the test solution are similar in retention time to the principal peak in the chromatogram obtained with reference solutions of Estrone Sodium Sulfate and Equilin Sodium Sulfate.

在含量测定项下记录的色谱图中，供试品溶液两个主峰的保留时间应分别与对照品中雌酮硫酸钠和马烯雌酮硫酸钠峰的保留时间一致。

Further examination found series water roll by driving in the direction of the bearing parts of lubricating oil pipe jam, turning parts of serious failure of the bearing and axle journal and bearing friction between Chin, lead ball cage falling apart damaged, ball of excircle have varying degrees of wear deformation, some ball has fragmentation or loss.

进一步查抄，发掘串火辊靠传动标的目的的轴承部位的润滑油管堵塞，轴承动弹部位惨重失油，轴颈与轴承之间爆发了不一摩擦，导致轴承滚珠保留架散架败坏，滚珠的外方有不同水平的磨损变形，有些滚珠已破裂或不保留。

Smarter retention - Values of various host and service directives that can be retained across program restarts are now only retained if they are changed during runtime by an external command.

更加智能的保留-在运行期间被一个外部命令改变的不同主机和服务指令的值，现在将会在重启后保留。

File, and that the original file attributes are preserved, thuspreserving ownership information.

而且原始文件的属性也保留了，从而保留下了自己原来的信息。

Preventing and controlling infection, in addition, used the Chinese native purgative ( compound prescription decoction DA CHENG QI ): Chinese rhubarb 20g ( post - decocting ), mirabilite 15g , officinal magnolia, Fructus aurantii immaturus , the peach kernel , the giant knotweed , the herbaceous peony , the dandelion , fumitory each 15g , fresh licorices 6g , the water dococtum 200ml treatment , by stomach tube pours into group every day two , each time 100ml , retains for two hours , by high retention enema group every day one , each time 200ml , when enema , the buttocks raise 10cm , the liquid level are apart from anus 50—60cm , 7days are a treatment course .

胃管注入组每日两次，每次100ml，保留两小时，期间暂停胃肠减压(中药胃管注入后胃肠减压器即予夹管，两小时后放开)；高位保留灌肠组每日一次，每次200ml，采用左侧卧位，灌肠时臀部抬高10cm，液面距肛门50～60cm，插入肛管约25～30cm，药液温度保持在40～42℃，7天为一个疗程。

There may also be changes in other gut hormones such as GIP but in terms of the therapeutic response one of the advantages is that the sensitivity to GLP 1 is retained in type 2 diabetes patients where as the sensitivity to GIP is not.

其它胃肠道激素例如GIP 也可能会有所改变，但其治疗优势之一是其保留了2型糖尿病患者对GLP-1的敏感性，而没有保留对GIP的敏感性。
