双管的

It is thought that the advantages of this method are:①dialyze completely beause of the volume of blood flow up to 200 to 300ml per minute ,②affect cardiovascular system alighily beause of blood flow form vien to vein during the pocess of hemodialysis ,③keep patients moving freely,and ④indwell catheter several weeks.

作者认为锁骨下静脉双胜留置导管血液透析的优点很多，首先，血流量可达200～300ml／min，能保证充分透析；另一方面透析时血液循环是静脉到静脉，对心血管系统影响小；该部位插管病人活动不受限，且导管留置时间可长达数周，所以不仅可作和临时性血透通路，也可作为长期维持性血液透析的血透通路。

Because of the two sets of independent magnetic deflection systems the full screen image composes two separate unit images.

双峰式显示管采用了两组相互独立的磁偏转系统，因此它显示的整幅图像是由两幅单元图像拼接而成。

Vibration frequency modes of quasi-one-dimensional SiO2 clusters with one chain, two chain, three- and four- membered ring structures were calculated according to the density-functional theory.

运用密度泛函理论，计算了4～24个单元的准一维单链、双链、三元环、四元环管状构型SiO2团簇的振动频率。

This paper is presented in a AT89C51 microcontroller as the core to the simple power line loading dual signal recognition system design. In this system, we design the integrated power, frequency signal generator, and use of four light emitting diode as Display interface, double-button switch-mode power line load control signal.

本文就是介绍了以一种以AT89C51单片机为核心的简单两路路电力线加载信号识别系统的设计，在系统中，设计了集成电源、频率信号发生器，并运用4个发光二级管作为显示界面，采用双按键开关模式控制电力线加载信号。

On some units, the dual-37mm AAA gun on the bow deck was replaced by a more powerful single-barrel 85mm gun.

在一些扫雷舰上，在舰艏甲板上的双-37毫米AAA炮被一座更有威力的单管85毫米炮代替。

Chapter 4 dissertates the work principle of Single-Pole Single-Throw PIN switch and Single-Pole Double-Throw PIN switch respectively.

第四章分别论述用PIN管设计的单刀单掷开关和单刀双掷开关的工作原理。

Cerebral hemorrhage rat models were established via injection of autologous arterial blood in caudate nucleus. Two days after modeling, 5 μL BrdU-labeled human embryonic NSCs suspension was transplanted at four points surrounding hematoma cavity in the rats. After 1 and 2 weeks, rats were sacrificed. Adjacent sections were doubly stained by BrdU/microtubule-associated protein 2 (MAP-2) and BrdU/glial fibrillary acidic protein.
