延伸率的英文单词
## 一、“延伸率”的英文单词
“延伸率”:elongation或percentage elongation。
## 二、单词释义
1. elongation
- 名词,主要含义为延长、伸长、拉长;在材料科学等领域指材料在受力作用下的伸长程度,即延伸率。
2. percentage elongation
- 这是一个名词短语,直译为“百分比伸长”,也就是延伸率的一种表达,强调伸长量相对于原长的百分比。
## 三、单词用法
1. elongation
- 可作主语、宾语等。例如:The elongation of the wire is
measured under different tensile forces.(在不同拉力下测量金属丝的延伸率。)
- 常与介词of搭配,表示“……的延伸”。例如:elongation of the
material(材料的延伸)。
2. percentage elongation
- 作主语、宾语等。例如:The percentage elongation is an
important parameter to evaluate the ductility of a metal.(延伸率是评估金属延展性的一个重要参数。)
## 四、近义词
1. strain - 名词,有应变、拉紧的意思,在材料力学中与延伸率概念相近,都表示材料受力后的变形情况。例如:The strain of the rod under axial
load is similar to its elongation in a sense.(在某种意义上,杆件在轴向载荷下的应变与其延伸率相似。)
2. extension ratio
- 名词短语,延伸比,也可用于描述材料的伸长情况,与延伸率相关。例如:The extension ratio can be used to calculate the
elongation percentage approximately.(延伸比可用于近似计算延伸率。)
## 五、短语搭配
1. elongation at break
- 断裂伸长率。例如:The elongation at break of this polymer is
relatively high.(这种聚合物的断裂伸长率相对较高。)
2. tensile elongation
- 拉伸延伸率。例如:We need to test the tensile elongation of
the sample.(我们需要测试样品的拉伸延伸率。)
3. uniform elongation
- 均匀延伸率。例如:The uniform elongation reflects the
material's ability to deform evenly.(均匀延伸率反映了材料均匀变形的能力。)
## 六、双语例句
1. The elongation of this metal rod is within the acceptable range.(这根金属棒的延伸率在可接受范围内。)
2. We measured the percentage elongation of the plastic sheet.(我们测量了塑料片材的延伸率。)
