advection

advection的音标为[ədˈvektʃən]，意思是前向或纵向运动。其基本翻译为“（热量、动量等的）传递，扩散；被带往；被推移；被推移量。

速记技巧：利用发音规律记忆单词，可以将单词拆分记忆，如：ad-ve-ction。此外，多进行词义辨析和语境应用，有助于更扎实地掌握词汇。

Advection的英文词源可以追溯到拉丁语ad-（向）和-veyre（带、引导）的组合，意为“引导、引导移动”。

变化形式：复数形式为adversions，比较级为advectional，最高级为advectionalest。

相关单词：

1. Convection（对流）：与advection同源，意为“引导移动”，指流体中质点由于密度差而产生的自然运动。

2. Migration（迁移）：指人或事物随时间的推移而发生转移、变化，与advection有相似的含义。

3. Adjacent（相邻的）：表示两个事物之间没有明显的界限，可以相互渗透，类似于advection的引导性质。

4. Deviation（偏离）：指偏离原来的方向或轨道，与advection有相反的含义。

5. Retardation（减缓）：指速度、进程等方面的减慢或延迟，与advection有相似的含义。

6. Advocate（倡导者）：指积极倡导某种观点或行动的人，与advection有相关的含义。

7. Displacement（位移）：指物体在空间中的位置变化，类似于advection的引导移动。

8. Substantiality（实质性）：表示事物的实质或核心，与advection的引导性质相反。

9. Adjacentness（相邻性）：表示两个事物之间的接近程度，类似于advection的引导性质的反义词。

10. Deviationism（偏离主义）：指对主流观点或价值观的偏离或背离，与advection有相似的含义。

advection常见短语：

1. advection velocity 迁移速度

2. advection heat transfer 热对流

3. advection equation 迁移方程

4. advection-diffusion 迁移-扩散

5. bulk advection 总体迁移

6. mean advection 平均迁移

7. local advection 局部迁移

双语例句：

1. The heat is mainly transported by convection rather than diffusion, due to the strong advection of air currents. 由于气流强烈地迁移，热量主要通过对流而不是扩散进行传输。

2. The particles are advected by the fluid flow and their motion is affected by the velocity and direction of the flow field. 颗粒被流体流动所迁移，其运动受到流场速度和方向的影响。

3. The advection of heat and mass in the atmosphere is a complex process that needs to be carefully accounted for in numerical models. 大气中热量和质量的迁移是一个复杂的过程，在数值模型中需要仔细考虑。

英文小作文：

Advection is a process where a substance is transported by a moving fluid. It occurs in many natural and man-made systems, such as the atmosphere, ocean, and river systems. In the atmosphere, advection is responsible for transporting heat and moisture, which are essential for weather and climate processes.

One example is the advection of clouds. When air rises, it cools and condenses to form clouds. However, if the air is moving, the clouds may be advected in a different direction, resulting in changes in the weather patterns. Another example is the advection of pollutants in the atmosphere, which can affect air quality and public health.

Advection is also important in fluid mechanics, where it is used to describe the motion of fluids in a moving flow field. Understanding advection and its effects is crucial for developing accurate numerical models of fluid flows and for predicting their behavior under different conditions.
