A few apomorphic character states, such as simple perforation plates, helical thickenings in secondary walls of vessels and septate fibers, can be found in Schisandraceae, which make this family a mosaic with both plesiomorphic and apomorphic character states.

此外，该科木材还具有单穿孔板导管、导管次生壁具螺纹加厚、具分隔纤维等较为特化的性状状态，这种性状进化水平的异等级现象，使五味子科表现出不同进化水平性状的镶嵌组合。

Our results showed that the transportation of JA from phloem to xylem occurred mainly through ray parenchyma cells and cambium regions, and that JA could be transported rapidly upwards and downwards through vessel tube and sieve tube.

3H—JA分布在筛管、次生韧皮部的薄壁细胞和射线细胞、形成层区以及导管、次生木质部的薄壁细胞和射线细胞，其中，在韧皮部和木质部的射线细胞及筛管、导管壁周围分布最多。

Successful tracheal intubation wasverified using the following criteria: 1 identification ofthe trachea and tracheal rings, 2 visualization of vocal cords,3 widening of glottis as the tracheal tube passes through,and 4 tracheal tube position above carina and demonstrationof movement of the chest wall visceroparietal pleural interface(i.e., sliding sign) after manual ventilation of the lungs.

成功的气管插管通过如下的标准证实：1）辨别气管和气管环，2）可见到声带，3）当气管导管置入时声门变宽，4）隆突上气管导管的位置以及手控通气时胸壁内脏壁胸膜界面的运动。

Patients admitted to an intensive care unit were prospectively assigned to have a CVC and AC connected with either a needle-free valve connection system or a three-way stopcock connection (3WSC).

在重症监护室病人接受被安排好的用无针开关连接系统或者用三通开关连接系统连接中央静脉导管和动脉导管，在这两组中的病人病情相似。

This article reviews the clinical application of video technology instruments such as videolaryngoscope, video laryngeal mask, video-optical intubation stylet and visualized endotracheal tube, its prospect development is mentioned also.

本文就视频喉镜，视频喉罩，视频气管导管芯以及可视性气管导管等视频技术的临床应用及发展前景作一综述。

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.

研究表明：桉树不同家系间木材物理力学性质和化学组成存在差异；粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异，株间、株内木材材色存在变异；桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异，在同一家系或同一无性系中，株间和株内也存在着相同的变化规律；桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关，侵填体含物越丰富，纹孔附物越多，桉材越容易皱缩；最大瞬间皱缩是能产生更大干燥降等的临界点，在制定干燥工艺时，必须在最大瞬间皱缩发生时，采用温和条件，使已产生最大瞬间皱缩的细胞尽可能多的恢复，尤其不能使其产生永久变定；在常温条件下，影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量；而对于瞬间皱缩和最大瞬间皱缩，几乎所有细胞都参与它们的形成过程；对于易皱缩的桉树木材，间歇干燥是最有前途的干燥方法。

In this prospective, randomized, controlled, unblinded study, we compared colonization rates of a standard, unimpregnated central venous catheter with rates for silver-coated and chlorhexidine-silversulfadiazine-impregnated CVC.

在这个非盲的、随机对照的前瞻性研究中，我们比较了标准的无预充剂的中心静脉导管和银涂层及预充洗必太磺胺嘧啶银两种中心静脉导管的菌落率。

Some catheters have "flashback" caps with holes in the center to allow air in the catheter to be displaced by blood when the venipuncture is made.

一些导管有"倒叙"的最高限额洞为中心，使空气中的导管将流离失所的血液时，静脉穿刺是。
