Structural mechanics refers to how structures behave under various forces. Engineers use principles from this field to design buildings, bridges, and other items to ensure they can withstand loads and stresses. For example, when designing a suspension bridge, engineers need to know the weight of vehicles that cross it (live load) and the bridge's own weight (dead load). They must also calculate how earthquakes and high winds may affect the bridge.

Recently developed "smart" materials change their properties in response to external stimuli, such as temperature, light, or electrical fields. Shape-memory alloys (SMA) can "remember" their original shape. After being deformed at a lower temperature, some SMAs can return to their original shape upon heating. Applications for this technology include orthodontic wires and stents for medical purposes and wing flaps and jet engine components in aerospace.

Experts in structural mechanics use computer simulations to identify potential weaknesses and optimize designs for safety and performance. Nevertheless, predicting the long-term behavior of structures under real-world conditions remains a challenge. Environmentally sustainable design is also taking on greater importance. Engineers increasingly use eco-friendly materials and design structures to minimize energy consumption.

该题为词汇题,询问单词含义:文中“optimize”一词在意思上最接近? 解题思路:此题需要结合上下文语境推测单词含义,关键是理解该词所在句子的逻辑。 按照题目提示定位原文中第三段里“optimize”出现的地方,在:“Experts in structural mechanics use computer simulations to identify potential weaknesses and optimize designs for safety and performance.(结构力学专家利用计算机模拟来发现潜在弱点,并优化设计,从而提高安全性和性能。)” 该句话的逻辑是专家发现了潜在弱点(identify potential weaknesses)→为了安全性和性能(for safety and performance.)做出了行动,即“optimize designs”,因此可以推测optimize与“改进”、“提升”有关。 分析选项: A.Create(创造)结合语境可以得知,optimize 是在已有设计的基础上进行改进,而不是从无到有地创造,排除。 B.Perfect(使完善)符合语境,正确。 C.Analyze(分析)前面的“identify potential weaknesses”已经属于分析过程,optimize 是在分析之后的改进动作,排除。 D.Test(测试)computer simulations可能包含测试过程,但 optimize 不等于 test,排除。
