Whether it is precisely measuring flour and sugar for baking cakes or controlling the amount of seasonings in cooking, it can be easily achieved, making food preparation more convenient. In the commercial field, such as supermarkets and shopping malls, the electronic scale is used for weighing and pricing goods, ensuring the fairness and accuracy of transactions. In industrial production, the electronic scale is used for weighing raw materials and quality inspection of products, playing an important role in ensuring product quality and production efficiency. There are many types of electronic scales, ranging from small household ones to large industrial ones, to meet the needs of different scenarios.

水準儀主要用于測量地面兩點之間的高差。它通過望遠鏡和水準器來實現(xiàn)精確的水平視線測量。在建筑工程中，水準儀是施工測量不可或缺的工具。例如，在建筑施工過程中，施工人員需要使用水準儀來確定建筑物的基礎標高，確保建筑物的垂直度和平整度。通過水準儀的測量，可以精確地控制每一層樓面的高度，使整個建筑結構符合設計要求。在道路建設中，水準儀用于測量道路的縱坡和橫坡，以保證道路的排水性能和行車舒適性。此外，水準儀還廣泛應用于水利工程、土地測繪等領域。現(xiàn)代水準儀結合了光學和電子技術，具有更高的測量精度和效率，為各種工程測量提供了可靠的保障。

The level is mainly used to measure the height difference between two points on the ground. It achieves precise horizontal line of sight measurement through a telescope and a level vial. In construction engineering, the level is an indispensable tool for construction surveying. For example, during the construction process, construction workers need to use the level to determine the elevation of the building foundation to ensure the verticality and flatness of the building. Through the measurement of the level, the height of each floor can be accurately controlled, making the entire building structure meet the design requirements. In road construction, the level is used to measure the longitudinal and transverse slopes of the road to ensure the drainage performance and driving comfort of the road. In addition, the level is also widely used in water conservancy projects and land surveying. Modern levels combine optical and electronic technologies, offering higher measurement accuracy and efficiency, providing reliable support for various engineering surveys.

經(jīng)緯儀是一種用于測量角度的儀器，它可以測量水平角和豎直角。在建筑施工中，經(jīng)緯儀主要用于建筑物的定位和放樣。例如，在大型建筑的施工過程中，施工人員需要使用經(jīng)緯儀來確定建筑物的四個角點的位置，以確保建筑物的平面位置準確無誤。通過經(jīng)緯儀的測量，可以精確地控制建筑物的軸線方向，使建筑物的各個部分能夠按照設計圖紙進行施工。在地形測繪中，經(jīng)緯儀用于測量地形的起伏變化，獲取地形的詳細信息。它可以幫助測繪人員繪制出精確的地形圖，為土地規(guī)劃、工程建設等提供重要的基礎數(shù)據(jù)。經(jīng)緯儀的測量精度高，操作相對復雜，需要專業(yè)的人員進行操作。隨著技術的發(fā)展，現(xiàn)代經(jīng)緯儀也逐漸實現(xiàn)了自動化和數(shù)字化，提高了測量的效率和準確性。

The theodolite is an instrument used for measuring angles, including horizontal and vertical angles. In construction, the theodolite is mainly used for the positioning and layout of buildings. For example, in the construction of large buildings, construction workers need to use the theodolite to determine the positions of the four corners of the building to ensure the accurate plan position of the building. Through the measurement of the theodolite, the axis direction of the building can be precisely controlled, allowing the various parts of the building to be constructed according to the design drawings. In topographic surveying, the theodolite is used to measure the undulations of the terrain to obtain detailed topographic information. It can help surveyors draw accurate topographic maps, which provide important basic data for land planning and engineering construction. The theodolite has high measurement accuracy and relatively complex operation, which requires professional personnel to operate. With the development of technology, modern theodolites have gradually achieved automation and digitization, improving the efficiency and accuracy of measurement.

水平泡是一種簡單而有效的水平測量工具。它通常是一個裝有液體的小玻璃管，液體中有一個氣泡。當水平泡放置在被測物體表面時，通過觀察氣泡的位置可以判斷物體表面是否水平。水平泡的使用非常方便，在日常生活中，人們可以用它來檢查家具是否擺放平穩(wěn)，如桌子、柜子等。如果氣泡位于玻璃管的中間位置，說明物體表面是水平的；如果氣泡偏離中間位置，則說明物體表面存在傾斜。在一些小型的安裝工程中，如安裝吊燈、掛畫等，水平泡也可以用來確保安裝的水平度，使安裝效果更加美觀。水平泡結構簡單、成本低廉，是一種實用的水平測量工具，適合在各種需要快速判斷水平的場合使用。

The level vial is a simple and effective tool for level measurement. It is usually a small glass tube filled with liquid, with a bubble in the liquid. When the level vial is placed on the surface of the object to be measured, the level of the surface can be judged by observing the position of the bubble. The use of the level vial is very convenient. In daily life, people can use it to check whether furniture is placed steadily, such as tables and cabinets. If the bubble is in the middle of the glass tube, it means that the surface of the object is level; if the bubble deviates from the middle position, it means that the surface of the object is tilted. In some small installation projects, such as installing chandeliers and hanging pictures, the level vial can also be used to ensure the levelness of the installation, making the installation effect more beautiful. The level vial has a simple structure and low cost. It is a practical tool for level measurement and is suitable for use in various occasions where the level needs to be quickly judged.
