水平仪、水准仪、经纬仪的区别？ What is the difference between a spirit level, a spirit level, and a theodolite?

水平仪是测量小角度的常用量具。在机械工业和仪器制造中，它用于测量机床设备导轨的平整度和平行度、设备安装的水平位置和垂直位置等。根据水平仪的不同形状，可分为框架水平仪和条形水平仪。

水准仪（Theodolite）它用于测量赤经和赤纬度。它是一种观测设备，具有多种天文望远镜特征，测量水平角度和垂直角度，用于地球测量、鸟类观察和星体观察。它不适合长期暴露的天文摄影。经纬度不仅可以指出海洋上船舶的位置，还可以简单地让每个人都知道一个物体的确切位置。

经纬仪（level）建立水平视线测量路面两点之间高度差的仪器。主要部件有望使用眼镜、管道水准器(或补偿器)、垂直轴、底座和脚螺旋。根据结构分为微倾水准仪、自动安平水准仪、激光水准仪和数字水准仪(也称为电子水准仪)。

根据精度，可分为精密水准仪和普通水准仪。

A level is a commonly used measuring tool for measuring small angles. In the mechanical industry and instrument manufacturing, it is used to measure the flatness and parallelism of machine tool equipment rails, as well as the horizontal and vertical positions of equipment installation. According to the different shapes of the spirit level, it can be divided into frame spirit level and strip spirit level. Theodolite is used to measure declination and declination. It is an observation device with various astronomical telescope features, measuring horizontal and vertical angles, used for Earth measurement, bird observation, and celestial body observation. It is not suitable for long-term exposure in astronomical photography. Longitude and latitude can not only indicate the position of ships on the ocean, but also simply let everyone know the exact location of an object. A theodolite is an instrument used to establish a horizontal line of sight for measuring the height difference between two points on a road surface. The main components are expected to use glasses, pipeline level (or compensator), vertical axis, base, and foot screw. According to the structure, it can be divided into micro tilt level, automatic leveling level, laser level, and digital level (also known as electronic level). According to accuracy, it can be divided into precision level and ordinary level.
