Based on our results, we deduce that DsbE protein may maintain the thiols of apocytochrome c in a reduced form, which is beneficial to heme insertion.

基于以上的实验结果，我们推测：DsbE可以维持脱辅基细胞色素c的巯基处于还原态，以利于卟啉的插入。

Infrared Strobe Infrared Strobes provide a positive identification of designated Landing Zones , allowing precise insertion of chalk groups .

红外线频闪器为指定着陆点提供了易辨认的信号，使得

Materials for orifice plates, meter/transmitter internal process wetted parts, and insertion type elements shall be in accordance with piping specifications except that material shall be minimum Type 316 stainless steel.

孔板、仪表/变送器的内部浸湿部件和内置型元件的材料，除了材料的最低类型是316不锈钢的，应遵照配管的规范。

SINEs insertion can be stably delivered to descendants, thereby, SINEs can provide the reliable evolutionary information, and used as molecular markers for phylogeny events within 50Mys, such as the levels of family and order.Cyprinidae, the largest fish family, comprises approximately 210 recognized genera and 2010 species.

鲤科鱼类是世界上现生鱼类中最大的一个科，约有210属2010个种，但有关鲤科鱼类中SINEs的研究却很少，目前相关的报道仅限于斑马鱼基因组内；而有关利用SINEs插入位点信息进行鲤科鱼类系统进化的研究更没有报道。

The SINEs RNA were transcripted by polymerase III; the transcripts can be reversely transcribed and the DNA products inserted into the host genome. The insertion of a SINE can be asseumed to be unidirectional since there is no known mechanism to precisely remove SINEs after their fixation of the host genome.

SINEs插入基因组后，很难在其相同位点精确的去除，能相对稳定地遗传；因此为系统进化分析提供了良好的分子标记，并被认为在物种50Mys的进化事件上能提供比较可信的进化信息，尤其是在科属以下的物种中。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
