absolute value的音标为[ˈæbsəluːt ˈvæljuː]:绝对值。
基本翻译为“绝对值,绝对量”。在数学中,绝对值是指一个数在数轴上所对应点到原点的距离。
速记技巧可以联想到数学中的绝对值符号,用英文表示即为“abs”,因此可以将absolute value简记为“abs大写”。同时,也可以联想到英文单词“value”,表示价值,因此也可以将absolute value理解为“绝对价值”。
以上内容仅供参考,建议使用英文单词记忆更高效。
绝对值的英文词源是absolute,这个词源于拉丁语absolutus,意思是“完全的,无条件的”。absolute的词形变化包括副词absolutely,形容词absolutely certain或absolute的否定形式absolutely not。相关单词包括:
opposite绝对对立面;相反的:opposite direction相反的方向
unrelated不相关的;不相干的
invariable不变的;恒定的
ultimate最终的;极端的
absolute value绝对值
absolute motion绝对运动
absolute zero绝对零度
absolute majority绝对多数
absolute monarch绝对君主制
absolute majority绝对优势
以上单词都与absolute这个单词有很强的关联性,并且都反映了其不同的含义和用法。绝对值这个词在数学中尤其重要,表示一个数的正负号被去除,得到的结果就是绝对值。
常用短语:

英文小作文:
Absolute values are an essential concept in mathematics and physics, as they provide a way to measure the magnitude or size of a number, vector, or graph. Absolute values are particularly useful in situations where the direction or orientation of a quantity is not important, such as in measurements of length, speed, and temperature.
When dealing with numbers, the absolute value of a number is simply its distance from zero. For example, the absolute value of -5 is 5, and the absolute value of 3 is also 3. This concept can be extended to vectors and graphs, where the magnitude of a vector or the size of a graph provide a measure of its overall magnitude or extent.
In physics, the concept of absolute values is essential in measuring forces, velocities, and other quantities that do not depend on a particular reference frame. For example, the speed of light is a constant regardless of the motion of the observer, making it possible to compare speeds between different systems of measurement. Similarly, the temperature of an object is independent of its surroundings, making it possible to compare temperatures between different environments and conditions.
Overall, the concept of absolute values provides a useful way to measure and compare quantities that are independent of their specific context or reference frame. It is essential in many areas of science and mathematics, making it an essential tool for any researcher or scientist.
