作文

In engineering and construction, the term permissible clearance refers to the minimum distance that must be maintained between two objects or surfaces to ensure safety and functionality. This concept is crucial in various fields such as civil engineering, mechanical design, and aviation. For instance, in the context of bridges, the permissible clearance is the vertical space required above the roadway to allow for the safe passage of vehicles, including oversized loads. If this clearance is not adequately calculated, it could lead to accidents or damage to both the bridge and the vehicles. Similarly, in mechanical systems, the permissible clearance between moving parts is essential to prevent friction and wear. For example, in an engine, the pistons must have a specific clearance from the cylinder walls to function efficiently. Too little clearance can cause overheating and failure, while too much can result in loss of power and efficiency. This balance is vital for the longevity and performance of the machinery.In aviation, permissible clearance is critical for ensuring that aircraft can safely take off and land. Airports are designed with specific clearances around runways and taxiways to accommodate the wingspan of different aircraft types. If these clearances are not adhered to, it can result in collisions or accidents during flight operations. Therefore, understanding and applying the concept of permissible clearance is fundamental in maintaining safety standards across various industries.Moreover, regulations and guidelines often dictate the permissible clearance in construction projects. Building codes specify the minimum distances required between structures, utilities, and other installations to ensure safety and accessibility. For example, in residential areas, there may be regulations on how close a fence can be built to a property line, or how far electrical installations must be from water sources. These rules are designed to protect individuals and property from potential hazards.The determination of permissible clearance involves careful calculations and considerations of various factors, including the materials used, environmental conditions, and the intended use of the structures or systems involved. Engineers and designers must account for thermal expansion, vibration, and other dynamic forces that can impact the spacing between components. Failure to do so can lead to structural failures, increased maintenance costs, and compromised safety.In conclusion, the concept of permissible clearance is a fundamental aspect of engineering and design across multiple disciplines. It ensures that systems operate safely and efficiently while minimizing risks to people and property. As technology advances and new materials are developed, the understanding and application of permissible clearance will continue to evolve, highlighting the importance of this principle in modern engineering practices.

在工程和建筑领域，术语permissible clearance指的是必须保持在两个物体或表面之间的最小距离，以确保安全和功能。这个概念在土木工程、机械设计和航空等多个领域至关重要。例如，在桥梁的上下文中，permissible clearance是指路面上方所需的垂直空间，以允许车辆（包括超大货物）的安全通行。如果这个间隙没有得到适当的计算，可能会导致事故或对桥梁和车辆的损坏。同样，在机械系统中，移动部件之间的permissible clearance对于防止摩擦和磨损至关重要。例如，在发动机中，活塞与气缸壁之间必须保持特定的间隙，以有效运作。间隙过小会导致过热和故障，而间隙过大则会导致动力和效率的损失。这种平衡对于机械的耐用性和性能至关重要。在航空领域，permissible clearance对于确保飞机安全起降至关重要。机场的设计在跑道和滑行道周围有特定的间隙，以适应不同飞机类型的翼展。如果这些间隙未能遵守，可能会导致飞行操作中的碰撞或事故。因此，理解和应用permissible clearance的概念是维护各行业安全标准的基础。此外，法规和指南通常规定了建筑项目中的permissible clearance。建筑规范规定了建筑物、公共设施和其他安装之间所需的最小距离，以确保安全和可达性。例如，在住宅区，可能会有关于围栏距离物业线的建造限制，或电气设施与水源之间的距离要求。这些规则旨在保护个人和财产免受潜在危险。permissible clearance的确定涉及仔细的计算和对各种因素的考虑，包括使用的材料、环境条件和相关结构或系统的预期用途。工程师和设计师必须考虑热膨胀、振动和其他动态力，这些因素可能影响组件之间的间距。如果不这样做，可能会导致结构故障、维护成本增加以及安全隐患。总之，permissible clearance的概念是多个学科工程和设计的基本方面。它确保系统安全高效地运行，同时将对人员和财产的风险降至最低。随着技术的进步和新材料的发展，对permissible clearance的理解和应用将继续演变，突显这一原则在现代工程实践中的重要性。
