Vancomycin was directly coupled onto Tenta Gel S NH〓 or PEGA resin through its C-terminus. HR/MAS NMR studies indicated that conformation of PEGA-bound vancomycin was the same as free vancomycin, and Ac〓-L-Lys-D-Ala-D-Ala interacts with PEGA-bound vancomycin the same way that it interacts with free vancomycin.

本文将万古霉素C端分别连接到Tenta Gel S NH〓和PEGA树脂上，利用高分辨魔角核磁共振技术研究了万古霉素在固相载体上的构象变化以及与Ac〓-L-Lys-D-Ala-D-Ala的相互作用。

叶的95%乙醇提取物中分离得到了4个化合物，经波谱分析，其结构分别鉴定为山萘酚－3-O-β-D-葡萄糖苷、山萘酚－3-β-D-（6-对羟基桂皮酰基）葡萄糖苷、L-2-O-甲基－手－肌醇和连翘苷。

By default, all programs and units arepiled with debug information enabled, but if you turn it off, using a {$D-}piler directive or a -$D- option, themand-linepiler will not be able to locate runtime errors.

默认情况下，所有的程序和单都是启用调试信息的，除非你用{-D}或-$D-指令关闭它，这样，命令行编译器就不能查找运行期间错误了。

The working principle and the structure of a hybrid magnetic bearing are investigated. The hardware of a digital controller system based on a fixed poind digital singal processor TMS320C25, as well as an A/D and D/A converter is presented.

壳聚糖是由大部分D-氨基葡萄糖和少量的N-乙酰-D-氨基葡萄糖组成，以β-(1，4)糖苷键连接起来的直链多糖，其结构类似于纤维素。

The shell polyose is glucosamine is composed by the majority of D- glucosamine and few N- the acetyl - D-, gets up the linear chain polysaccharide by β-(1,4) sugar glucoside keying, its structure is similar to the cellulose.

壳聚糖是由大部分D-氨基葡萄糖和少量的N-乙酰-D-氨基葡萄糖组成，以β-(1，4)糖苷键毗连起来的直链多糖，其结构类似于纤维素。

The French are generally more creative in their terms of abuse and they like to create the kind of powerful imagery that would not be out of place on the pages of a Flaubert novel, like, vous etes une pomme de terre avec le visage d'un cochon d'inde (you are a potato with the face of a guinea pig).

一般来说，法国人对损人的词汇更富有创造性，他们喜欢自己所创造的强有力的比喻就像福楼拜的小说一样不会过时，比如： vous etes une pomme de terre avec le visage d'un cochon d'inde 你是一个长着豚鼠脸的土豆。（你狗屁不是/一钱不值。

Ealuation of the exclusie use of calcium or itamin D3 showed no antifracture efficacy for patients receiing 800 IU of itamin D3 per day.44 Howeer, the mean concentration of 25-hydroxyitamin D increased from 15.2 ng per milliliter to just 24.8 ng per milliliter (37.9 to 61.9 nmol per liter), which was below the threshold thought to proide antifracture efficacy.8 Porthouse and colleagues,45 who ealuated the effect of 800 IU of itamin D3 per day on fracture preention, did not report concentrations of 25-hydroxyitamin D.

对单独服用钙或维生素D3的评价显示，每天服用800IU维生素D3没有抗骨折效果。平均25-羟基维生素D浓度从15.2ng/ml仅上升到24.8ng/ml(37.7到61.9nmol/l)，但仍低于认为可以产生抗骨折作用的阈值。Porthouse及其同事评价了每天800IU维生素D3对预防骨折的作用，并没有报道25-羟基维生素D浓度。

The results Showed that the highest transformation efficiency was obtained through the following transformation procedure: after preculture for 2 d, the explants were in fected 3 min with 50 mg/L acetosyringone and OD600=0.5 Agrobacterium culture liquid, and then co-cultivated for 2 d. Resistant shoots from leaf disks were screened on MS0.4 mg/L NAA + 100 mg/L Cef medium supplemented with 10 mg/L Km.

结果表明：2 d的预培养，OD600值约为0.5的农杆菌菌液添加50 mg/L AS，侵染时间3 min，2 d的共培养，从分化培养基获得的抗性芽在生根培养基MS+0.4 mg/L NAA+10 mg/L Km+100 mg/L Cef上进行延迟筛选，有利于获得较高的转化效率。
