First, calculating the pressure pulsation in the condition of different velocity and pulsant frequency through using CFD software, then calculate the ahead natural frequency and length of resonance, which offer a reference to the select of pipe length in Hot Blast Stove.

利用通用CFD软件计算不同速度、脉动频率下压力不均匀度沿管道的分布情况，同时计算出管内气柱的前几阶固有频率及共振管长，该方法为热风炉管道系统选取合适的长度提供了参考。

The present work specialized in the purification and open ing of the Multi-walled carbon nanotubes refluxed in concentrated nitric acid or air oxidation method respectively.

碳纳米管具有接近理想的一维纳米空间，而开口的碳纳米管中空管腔可做成纳米试管、虹吸管、超级吸附剂、催化剂载体和储能材料以及在中空的碳纳米管内填充外来物质等。

Or heat-pipe evacuated collector tubes with a flat absorber and a semicylindric absorber , relative solar irradiance changing with incident angles on various points of absorber s have been measured respectively by using a solar simulator.

以太阳模拟器为光源，对平面吸热板和半圆柱吸热板热管式真空集热管测定了玻璃罩管内吸热板表面各点随光线入射角变化的相对太阳辐照强度分布，给出了平面与半圆柱吸热板平均相对太阳辐照强度随人射角变化的规律及三维拟合公式，并对两种情况的实验结果进行了初步分析。

Contrast enhanced ultrasound and CECT or CEMRI are not fully superimposable, as UCA remain in the intraascular space, whereas the majority of currently approed contrast agents for CT and MRI are rapidly cleared from the blood pool into the extracellular space.

造影增强超声和CECT或者CEMRI不是完全重叠的，因为UCA停留在血管内，而目前大多数经批准的CT和MRI的造影剂会从血池中快速清除，并进入到细胞外间隙。

Testicular descent can get arrested at any point from the renal hilum to the external inguinal ring. Of all the undescended testes, 90% to 95% are low and in the inguinal canal.

双睾丸下降过程中可于肾门至腹股沟外环的任一点受到阻止，所有的隐睾中，90％－95％的位置较低，位于腹股沟管内。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
