differentials

differentials 的音标为 [ˈdɪfrəntɪəlz]，基本翻译为“差分；差异；偏微分方程；差分法”等。速记技巧为：利用发音相似的词汇进行联想记忆。例如，可以联想到different（不同的）和familiar（熟悉的）这两个词，可以记为“对熟悉的不同进行测量就是差分”。

differentials这个词来自拉丁语，意为“差异”或“变化”。它的变化形式主要有复数形式differentials，过去式differentiated和过去分词differentiated。

相关单词：

1. differentiation: 是一个重要的英语单词，意为“区分，区别”或“分类”。这个词在生物学和数学领域尤其常见，因为它们都涉及到差异和分类的概念。

2. differential calculus: 是一个数学术语，表示微积分学的一部分，专门研究差分和导数之间的差异。

3. differential equation: 是一个数学术语，表示一个包含导数的方程，它描述了一个系统的行为或变化。

在英语中，differentials这个词经常出现在科学和工程领域，特别是在物理学和数学中。它帮助我们理解变化和差异之间的关系，以及如何通过微积分来描述这些关系。以上就是关于differentials的一些信息。

differentials 的常用短语：

1. differential equation 微分方程

2. differential operator 微分算子

3. differential geometry 微分几何

4. differential entropy 差分熵

5. differential calculus 微分学

1. In differential geometry, we need to solve differential equations to understand the shape of curved space.（在微分几何中，我们需要解微分方程来理解弯曲空间的形状。）

2. The differential operator helps us to find the change of a quantity with respect to time or other variables.（微分算子帮助我们找到一个量随时间或其他变量的变化。）

3. In physics, differential entropy is used to measure the disorder of a system.（在物理中，差分熵用于衡量系统的无序程度。）

4. The differential coefficient determines the rate at which a quantity changes with respect to a variable.（微分系数决定了量随变量变化的速率。）

5. The differential equation of state is used to describe the relationship between pressure and volume of a substance.（状态方程微分方程用于描述物质压力和体积之间的关系。）

作文：

Differentials are essential in many fields, from mathematics to physics and engineering. They help us to understand how things change and how they are related to other variables. In physics, for example, differential equations are used to describe the motion of particles and systems of particles, while differential calculus is used to solve problems related to curves and surfaces. In engineering, differential operators help us to find the changes in quantities with respect to time or other variables, while differential geometry is used to understand the shape of curved spaces. Without differentials, many scientific and technological advances would be impossible.
