Level: an instrument for measuring the horizontal plane. It consists of a frame and an arc glass tube filled with ether or alcohol. There are bubbles in the tube, and the bubbles are always at the highest point of the tube. When the level is in a horizontal position, the position of the bubble is in the middle of the calibration of the test tube. Also called level.
Horizontal sentence: 1, he added that the helicopter can land safely when it crashes because the sensor matrix will detect the gyro or level of the aircraft at the moment of landing.
2. Just as the carpenter's tools include a tape measure and a level to ensure the correct size and installation of the cabinet, similar consistency can also be used for measuring software.
3. You can add your favorite digital filter or level meter.
4. Install the base on the paved foundation and level it with a level. Tighten the nuts on the anchor bolts to fixedly connect the base with the foundation.
5, provide a sufficient number of calibration steel tape theodolite and level.
6. Level the shelf with an alcohol level.
7. After the main engine is in place, use a level gauge to roughly adjust the level, and then install the loader after roughly adjusting the level.
8. Make sure that you have cleaned the surface of the measured object and the surface of the level.
9. Except for the stone level, there is no other instrument to measure the altitude of crossroads and important places in the northern plateau.
10. At present, when measuring and evaluating the parallelism error with a level, the data processing always adopts manual drawing method or calculation method.
1 1. Based on the theoretical derivation of the temperature compensation principle, this paper introduces the temperature compensation strategy in the intelligent electronic level.
12, leg level, warning signs are standard.
13. Introduce a new practical patent-electronic liquid level meter.
14. This paper introduces the development of a high-precision gun digital level, and expounds the related working principle and key technologies in detail.
15. The main difficulties to be overcome in the stable tracking of the moving communication system are gyro zero drift, level lag, tracking scanning speed and code disk counting when the motor rotates forward and backward.
16. The basic structure and measuring principle of common bubble level are introduced. The adjustment method of liquid level under laboratory conditions is also introduced.
17, the ancient Egyptians used a level and ruler for long-distance observation.
18, the level is here. He skillfully set up a tripod and looked around for a long time.
19. Use the mobile phone as a spirit level to display the bubble tube for detecting levelness and verticality. This software function is realized by using the gravity sensing function of the mobile phone.
20. Innovatively put forward the adjustment method of instrument survey datum with high precision level and the idea of error compensation of survey data system;
2 1. This scheme can combine the north finder and azimuth level well, and is suitable for all kinds of land vehicles and missile launch vehicles, which has high practical value.
22. The communication system has been successfully applied to digital electronic level.
23. With this level, the inclination and azimuth of the plane to be measured can be measured at the same time.
24. These two levels can not only measure the level, but also measure a certain inclination angle.
25. Align the balance frame with a level.
26. laser levels's scanning control model is introduced in detail in this paper, and the instrument is successfully designed and manufactured by using this model.
