两管的

Comparing with the two methods, spraying method will make carbon nanotubes well dispersed in the plastic surface and the conductive surface of the obtained materials will be evener and more stable.

结果表明：两种方法制成的抗静电覆膜都能大大降低塑料的表面电阻，但喷涂法更能使碳纳米管在塑料表面均匀分散，从而使塑料表面抗静电性能更加稳定。

The characteristic differences between these two dual flyback topologies are analyzed and compared in detail, and their respective application occasions are also indicated.

客观地分析和比较了这两种双管反激变换器的特性差异，并指出了两者的适用场合。

The latter considers two cases: piping or flowing sand caused by free water and soil heave caused by artesian water.

后者分别研究自由水引起的管涌及承压水产生的土基隆起两种情形。

The weighing test is to be carried out for both, weighing an anchor suspended to 82.5m of chain cable and verifying the time that required for the weighing (excluding the housing in the hawse pipe) does not exceed 9 min.

左右两只带有 82.5m 锚链的锚需要做起锚试验，确认所用时间不超过 9 分钟(不包括进入锚链管以后的时间)。

The metaphase plate would thus be the null point between two equal but oppositely directed and acting groups of kinetochore tubules.

中期板大概是两个相等而方向相反的放射状着丝点微管群之间的平衡点。

I collect the tithes and taxes, administer the communal lands, see that the garrison is provided for, supervise the junior officers who are the only officers we have here, keep an eye on trade, preside over the law-court twice a week.

我负责征收什一税和其他税款，掌管公共领地，照管着边防要塞不至于缺少供给，监督我们这里唯一的一个下级官员，顺带也管一下贸易，一周主持两次法庭的开庭审理。

For this nonlinear and time-dependent temperature field problem, two kinds of finite elements are presented here.

对于这类高度非线性的瞬态场问题，本文发展了两种一维温度管单元及其温度场的计算方法。

Traditional wind is in charge of joint to need to shape via flange fold, the two joint limit that will need to oversew and hem are clavicular.

传统的风管组合需经法兰折叠成型，将需缝补的两组合边和折边锁骨。

Working principle: Jet pumps work only two basic components: a rotation of the rotor and a fixed receiver tube (also known as fluid collection tube, Pitot tube).

工作原理：旋喷泵内只有两个基本工作部件：一个旋转的转子和一个固定的接收管。

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。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
