查询词典 tube

A pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

速度感应器，俗称空速管，最早就是法国工程师 Henri Pitot 先生发明，并在一个世纪后由另一位法国工程师 Henry Darcy 先生改进而成为现代形式的重要器件，广泛用于探测气体或液体的速度变化，并把数据传到给控制中心。

In 1895, Wilhelm Roentgen accidentally discovered that a cathode-ray tube could make a sheet of paper coated with barium platinocyanide glow, even when the tube and the paper were in separate rooms.

1895年，威廉·伦琴偶然发现阴极射线管能使涂有一层氰亚铂酸盐钡的薄相纸发光，甚至当阴极射线管和相纸分别放在不同的房间时也能发光。

We also find that the metal-to-semiconductor transition can be driven by squashing the armchair nanotube along any direction. In case one starts with squashing the tube along a direction that preserves the mirror symmetry, all that needs to be done is to squash the tube to a larger extent, to a point where spontaneous symmetry breaking occurs.

To solve this problem, according to the analysis of the quality factors of the X-ray, the measurement for X-ray tube voltage/current is presented based on Q-factor and its derived QL and QH-factor when X-ray tube energy bandwidth is defined.

针对传统的管电压/管电流测量方法虽然可以检测出X射线管电压/管电流误差值，但不能反映其质量特征的状况，在分析影响X射线质量高低的因素的基础上，引入了射线管能量带宽的含义，并由此提出了基于Q值及其派生QL值、QH值的射线管电压/管电流分析方法。
