查询词典 Sam

确定了分离纯化SAM的最优条件是：在pH值5.0时，含SAM浓度为3.0 g/L的上柱液，以6 L/h的流速，过装填D152树脂的离子交换柱(φ50 mm×1500 mm)后以去离子水和醋酸洗脱除杂，再用9 L到15 L浓度为50 mmol/L的硫酸以6 L/h的流速洗脱，可以分离得到纯度较高的SAM粗品。

The purity of SAM product was higher than 95％, and the overall recovery of SAM sulfate and SAM double salt of sulfate and p-tosylate were 60％ and 50％, respectively.

通过筛选，获得了对SAM有较好选择性离子交换能力、较易洗脱和再生的争光D113弱酸型阳离子树脂，研究了温度、pH等对SAM离子交换的影响，根据SAM在弱酸阳离子树脂D113上的等温交换平衡行为表现出较强的可逆性，考虑到交换基的弱电解质性质以及结合Donan膜平衡理论，建立了考虑pH影响的可逆离子交换平衡模型，该模型可以较好地描述SAM平衡浓度、pH对离子交换平衡的影响；通过对动态离子交换过程的研究，得到了SAM在D113树脂内的有效扩散系数的数量级为1.0E-9cm〓/s～1.0E-8cm〓/s。

Then SAM precipitation was carried out by picric acid and SAM precipitated is higher than 90％. After butanone extraction, acetone precipitation and SAM sulfate or SAM double salt of sulfate and p-tosylate formation, the stable SAM salt was obtained.

结果表明，苦味酸是一种选择性较好的沉淀剂，沉淀步骤得率在90％以上，制备SAM的硫酸盐的总得率在60％以上，而硫酸对甲苯磺酸双盐的得率在50％以上，产物的纯度达到了95％以上，已经达到了国外同类产品的质量指标。

Sam和Dean虽然成功与其父亲见面，但却被他劝喻两兄弟不要继续寻找他的下落，Sam不理爸爸的劝喻继续寻父，而Dean则听从父亲说话并前往捉鬼。

Austin: Ah...I really don't care about becoming home-coming prince...Austin: OK. Gimme a choice. You rather have rice cake or a big Mac?Sam: A big Mac, ha what does that matter?Austin: Well I like the girl with a heavy appetite. And besides, you just eliminated about 50%of the girls in our class. I think I'd remmeber those eyes...so beautiful.Sam: Mmm...Next question.?Austin: If I ask you to dance, does that count as a question?

Sam和她的secret boy相约在一个Halloween的化妆舞会上相遇，可是当王子真正站在Sam面前的时候，Sam却发现，他就是学校里的第1人气足球队长Austin，但是Austin并没有认出眼前的这位身着美丽纱裙的姑娘到底是谁，尽管他曾经在Sam 打工的餐厅见过她。

Sam 'Spike' Witwicky: If anyone finds this, my name is Sam Witwicky, and my car is alive...

Sam：如果有谁找到它，我的名字是Sam Witwicky，我的车是"活"的

To give consideration to both validity and reliability, six combinations are recommended when differentially expressed genes are less, RMA+fold-change, RMA+ SAM, RMA+ limma, PDNN+ fold-change, PDNN+SAM, and PDNN+limma. Three combinations are recommended when differentially expressed genes are more, dChip+ fold-change, dChip+SAM, and dChip+limma.

若同时注重信度与效度，我们推荐几种方法组合：当表现量差异基因个数少时，推荐RMA+fold-change、RMA+SAM、RMA+limma、PDNN+ fold-change、PDNN+SAM与PDNN+limma此六种组合；而当表现量差异基因个数多时，则推荐dChip+fold-change、dChip+SAM与dChip+limma此三种组合。

We present an improved DP-MBE SAM; secondly, un-voice analysis is introduced to the DP-MBESAM, so that the improved ASA system can be used not only to separate concurrent vowels but concurrent speech signals with unvoice as well.

针对基于DP-MBE SAM的混叠浊音听觉场景分析系统存在的问题，提出了改进的基于DP-MBE SAM的混叠语音听觉场景分析系统，包括两部分内容，第一，针对DP-MBE SAM在实际的应用中存在的求解矩阵奇异引起的参数模糊及混叠信号谐波频率相同引起的参数模糊问题，借鉴多帧内插方法，提出了改进的DP-MBE SAM；第二，在基于DP-MBE SAM的混叠浊音听觉场景分析系统加入清音分离环节，将系统的应用从浊音推广到含有清浊音的语音信号。

The optimum condition for separating and purifying SAM was using the solution at pH of 5.0 containing 3.0 g SAM per liter at the flow velocity of 6 L/h through the ion-exchange column (φ50 mm×1500 mm)filled with D152 resin. Impurities were removed first by eluting the column with double-distilled water and acetic acid, and then with 9 L to 15 L of sulfuric acid of 50 mmol/L concentration at the flow velocity of 6 L/h.

论文对SAM的性质、药理作用以及当前国际上关于SAM的研究进展进行了较为详尽的综述，并在此基础上确立了研究内容，取得了如下成果： 1利用本实验室构建的基因工程菌JM71发酵生产S-腺苷-L-蛋氨酸，在50 L发酵罐中发酵6天后，SAM终产量达到6 g/L发酵液。
