deflection

"deflection"的音标为[dɪˈflekʃn]，基本翻译为“偏转；弯曲；转移；偏离”等。速记技巧为：可以将其拆分为“de”和“flexion”两部分记忆，其中“de”意为“离开、偏离”，“flexion”意为“弯曲、变形”。

Deflection 的词源：

词根：de-（否定）+ flect（弯曲）+ ion（动作）→ 否定弯曲→ 偏转。

Deflection 的变化形式：复数形式为 deflections，过去式为 deflected，现在分词为 deflecting。

Title: Deflection and its Impact on Structures

Deflection is a common phenomenon in structures, whether it be a bridge, a building, or even a simple piece of equipment like a machine tool. Deflection occurs when a structure experiences forces that cause it to change shape slightly or significantly from its original design. This can have a significant impact on the structure"s performance and functionality, as well as its safety and stability.

For example, a bridge may experience deflection due to wind loads, traffic loads, or simply the weight of the structure itself. If this deflection is not properly monitored and adjusted for, it can lead to unsafe conditions and even structural failure. Similarly, a machine tool may experience deflection due to excessive heat or wear and tear, which can affect its accuracy and precision.

Fortunately, there are various methods available to address deflection, including adjusting the structure"s design, using stronger materials, or adding support structures to stabilize the structure. By understanding the causes of deflection and implementing appropriate measures, we can minimize its impact and ensure the safety and reliability of our structures.
