On the afternoon of November 22, 2012, the Beijing Municipal Science and Technology Commission organized an expert acceptance meeting on the subject of "Development of Standard Equipment for Large-caliber Thermal Energy Meters and Application of Thermal Measurement". Chief Engineer Yu Hong of the Municipal Bureau, Director Li Jingwu of the Science and Technology Department, President Yao Hejun of the Beijing Institute of Metrology and Inspection Science, Vice President Wang Zigang and members of the research team attended the meeting.
At the meeting, the expert group fully affirmed the significance and research results of this topic. This subject has developed a large-caliber thermal energy meter standard device, completed the research on the key technology of the large-caliber thermal energy meter standard device and the research on the application of heating measurement, and formed the "Research Report on the Key Technology of Large-caliber thermal energy meter standard device" The "Pilot Pilot Research Report" and "Research Report on the Mathematical Model of User's Thermal Sharing Technology Selection" have completed all the tasks specified in the task book and reached the specified technical indicators. For the first time in China, the subject has built a standard device with a maximum flow rate of 600m3 / h and an uncertainty greater than 0.1%. For the first time, the device adopts the technology of constant pressure overflow water tank and the air curtain structure on the weighing tank, which improves the accuracy of the device, fills the gap in the detection of domestic large-diameter thermal energy meters, and guarantees the smooth reform of the Beijing heating metering Implementation. The expert group unanimously agreed that the subject passed the acceptance and recommended to apply for scientific and technological awards as soon as possible.
L-shaped desk is a type of desk that is designed in the shape of the letter "L." It provides a spacious and efficient workspace, making it popular for home offices, corporate offices, and other work environments. The L shape allows for multiple work areas and provides ample space for tasks, computer work, and storage. Here are some key features and aspects of an L-shaped desk:
-
Shape and Configuration: L-shaped desks have two connected sections that form an L shape. One section is typically longer than the other, creating two distinct work areas. The longer side is often used for the primary workspace, such as a computer or writing area, while the shorter side can be used for additional workspace, storage, or as a secondary work surface.
-
Size and Dimensions: L-shaped desks come in various sizes to accommodate different office spaces and individual needs. The dimensions of the desk should be chosen based on available space and the amount of surface area required for work tasks.
-
Design and Style: L-shaped desks are available in different designs and styles to match various office aesthetics. They can range from minimalist and contemporary designs to more traditional or executive-style options. Consider the overall decor of your office or workspace when selecting the design of the desk.
-
Materials and Construction: L-shaped desks can be constructed using various materials, including wood, metal, glass, or a combination of these. The choice of material often impacts the desk's durability, appearance, and weight-bearing capacity. Consider your preferences for style, functionality, and maintenance when selecting the material for the desk.
-
Storage and Organization: Many L-shaped desks come with built-in storage options to help keep the workspace tidy and organized. These storage features may include drawers, shelves, cabinets, or a combination of these. Evaluate your storage needs and consider the availability of storage solutions in the desk design.
-
Cable Management: L-shaped desks often have built-in cable management systems or grommets to help organize and hide computer cables, power cords, and other wires. This feature helps create a cleaner and more organized workspace.
-
Flexibility and Modularity: Some L-shaped desks offer modular components or adjustable features that allow for customization and flexibility. These options can include detachable sections, adjustable height, or the ability to add additional accessories or storage units
