Although many predictors of a difficult laryngoscopic intubation have been developed, they all have low positive predictive values, and thus the unanticipated difficult laryngoscopic intubation will continue to occur in our day-to-day practice for the foreseeable future.

虽然已经有许多预测困难喉头镜插管的指标被提出，但是其正向的预测值皆很低，也因此在可见的未来未预期性困难喉头镜插管仍然会在日常的工作中发生。

In this paper, the carbon nanotubes made by CVD were purified by acid solution. Results indicate that the ports of CNTs were oxidated and opened up, the surface of CNTs bring a lot of oxygenous functions, which was useful for dispersion of CNTs in the water solutions.

采用液相氧化法对CVD法制备的碳纳米管进行了提纯，结果表明，经过提纯后碳管的端口被打开且表面产生了大量的含氧官能团，使其在水溶液中的分散性得到了改善。

The results show that the single-layered neural tube fails to form and the neural crest cells remain at the lateral regions in the explants with NTDs. However, the patterning of the neural tube is not affected as indicated by the normal expression of the preneural genes.

结果显示神经管闭合缺陷的移植体不能形成单层化的神经管，并且神经晴细胞滞留在侧面区域不能向背侧中线迁移，而对神经前体标记基因的检测显示神经管的背腹图式形成并未受到影响。

In addition,the domestic production situation was presented.Both design and manufacturing of the sectorial drum of the reforming reactor as well as the shell and tube exchanger were successfully accomplished with the collaboration of engineering institute,manufacturer and client.Particular equipment and technologies for manufacturing were developed.Difficulties in entirely revering,butting and strengthening of slotted tubes in reactor were solved.

设计单位与设备制造单位和用户密切合作，顺利地完成了重整扇形筒和列管式立式换热器的设计与加工；开发了专用加工设备和特殊的加工工艺，解决了反应器开口接管的整体翻边对接补强难题；在安装过程中确保了反应器壳体椭圆度与中心管的垂直度。

The Practical and New patent is to strack automatically the movement of the sun by a small sync unit using a mirror paraboloid and focus the sunsine on the surface of vacuum heat absorbing pipe, so as to heat the water in a single vacuum heat absorbing pipe with several times of energy,so that the water temperature rises till boils with heat exchange.

家用同步跟踪太阳能开水器是利用镜面抛物面在小型同步装置作用下自动跟踪太阳运动，以7倍于阳光直射的能量将阳光聚焦到真空吸热管的表面，对单根玻璃真空吸热管中的水进行加热，通过对流热交换，使容器中水温上升直至沸腾的太阳能开水器。

The results show that concentration of ownership has a significant impact on risk-taking. The higher the largest shareholder's shareholding percentage, the higher the risk-taking is; the higher the top five shareholders' shareholding percentage, the lower the risk-taking is. The percentage of untradeable shares, the size of the board of directors, the proportion of independent directors and the average remuneration of top 3 senior executives with the highest remuneration are negatively correlated to the risk-taking. However, the situation that the chairman or vice chairman concurrently holds the post of president or CEO increases the bank's risk exposures to a certain extent. Proportion of state-owned shares, the nature of the largest shareholder and the executives' shareholding have no significant impact on risk-taking.

结果表明，股权集中度对风险承担产生了显著的影响，其中第一大股东持股比例越高风险承担越高，而前五大股东持股比例越高风险承担越低；非上市流通股比例、董事会规模、独立董事比例以及薪酬最高的前三名高管的平均薪酬均与银行风险承担负相关；银行董事长同时兼任行长在一定程度上倾向于增加银行的风险承担；国有股比例、第一大股东性质和高管持股状况没有对风险承担产生显著影响。

In blow molding, a molten tube of thermoplastic material is formed, and then compressed air is used to blow up the tube, forcing the material to take the shape of the interior of a chilled blow mold.
