导管的

"We deeloped a simplified method for increasing pharyngeal pressure by deliering warm and humidified air at a continuous high flow rate through the open nasal cannula," they said.

&我们发现了一种简单的方法通过开放的鼻导管输送加热加湿的空气，以持续高流率提高咽部压力。&他们说。

Discussion: About the knot formation, most authors believe that the more the catheter is advanced into the epidural space, the greater is the theoretical potential of "kinking and knotting" of the catheter.

讨论：关於打结的形成，大部份的作者都相信，如果导管进入硬膜外腔越多，理论上它产生纠结的可能性越高。

The result shows that the resistance of tree species at the same site closely related to the number of vessel, rays' width, radium of lignified cell and wall thickness of sclereids, and the anatomical structure of the same tree species was different at different sites.

结果表明，不同树种在同一立地条件下的导管个数、射线宽度、木化细胞半径及韧皮部石细胞壁的厚度与树种的抗虫性密切相关；同一树种在不同立地条件下其内部解剖结构有所不同。

There are usually horizontal rather than the slanting end walls of tracheids. Vessel elements have lignified secondary cell walls and at maturity lack a living protoplast.

另外，导管分子具有木质化的次生细胞壁结构，成熟期的细胞内已经不存在活的细胞质。

Lodicules of the CMS lines with lighter CGG had more, bigger and unequal tracheae in SVB, and had bigger volume, heavier weight and lower water potential compared with the CMS lines with CGG. Similar to CMS lines, the B-lines had similar changes.

与种子裂颖重的不育系相比，种子裂颖轻的不育系浆片小维管束导管面积大、数目多且分布均匀、体积小、重量轻、水势低；且相应保持系也表现出大致相同的规律。

The block pattern has longer wedge guides and closely machined valve body channels for better control over the wedge throughout its travel.

这种关闭型结构具有比较长的楔板阀导管，其机械性能更加适合阀体中的运动轨道，更加容易对运动中的楔板进行控制。

This nondistensible patient connection line assembly (Fig. 1), fabricated of blue-striped tubing, with patient line stopcock, latex-free injection site, and red end plug, allows connection of a ventricular or lumbar drainage catheter directly to a drainage bag Fig.

本套患者连接线组件为不可伸展（图 1），由蓝色条纹的管子制作而成，配有患者连接线旋塞、不含乳胶的注射位点以及红色的端塞，用于将脑室或腰部引流导管直接连接到引流袋上（图 2）。

Serial blood samples via the dorsal aorta cannulae showed that the GH secretion of starved juvenile grass carp (bodyweight 0.5-1.0kg) was still episodic, but with higher values of average GH, basal GH, and peak GH.

检测由背大动脉导管抽取的连续血样的结果表明：饥饿状态下草鱼(体重为 0 。5- 1 。0kg)生长激素分泌仍是间歇性的，但饥饿明显提高其总体生长激素平均值、基础生长激素平均值和其最大峰值。

A typical stage-type distillation column consists of a vertical shell with a number of equally spaced trays mounted inside of it .each tray contains two conduits,one on each side, called downcomers.liquid flows through these downcomers by gravity from each tray to the one below.

典型的阶段-类型的蒸馏专栏有垂直贝壳与一些相等地隔开了它被装进的盘子。每个盘子包含二个导管，一在每边，藉由地心引力经过这些 downcomers 叫做 downcomers.liquid 流程上从每个盘子到那一在下面。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
