gyration

gyration 的音标是[ˌɡɪərɪˈeɪʃn]，基本翻译是“旋转；转动；摇摆；舞动”。速记技巧是：可以将单词分解为“g”、“y”、“r”、“e”、“n”五个字母，分别记忆。同时，也可以结合单词的意思来记忆，如“gyre”意为“旋转”，那么“gyration”就可以理解为“旋转的动作”。

gyration这个词的英文词源可以追溯到拉丁语中的gyra或gyratus，意为旋转或绕轴旋转。它的变化形式包括过去式和过去分词形式的gyrated或gyrating，以及现在分词形式的gyrating。

英文小作文：

Gyroscopes are amazing devices that have been used for centuries to maintain stability in motion. They work by using the gyroscopic effect, which is a property of rotating objects that cause them to resist changes in direction. In a gyroscope, this effect creates a constant torque that keeps the device spinning in the same direction, even when it is subjected to external forces such as wind or gravity.

In modern applications, gyroscopes are used in everything from spacecraft to automobiles to help maintain stability and prevent accidents. They are also used in precision instruments such as clocks and compasses to ensure accurate measurements and directional accuracy. Although they may seem like a strange device from another era, gyroscopes are still an essential tool for modern technology and engineering.
