基础例句

The microwave oven stopped working because the magnetron needs replacement.

微波炉不工作了,因为磁控管需要更换。

I learned that a magnetron generates the microwaves for cooking food.

我了解到磁控管产生用于烹饪食物的微波。

If the magnetron is faulty, the microwave won't heat properly.

如果磁控管有故障,微波炉就无法正常加热。

高级例句

In radar systems, the magnetron is crucial for producing high-frequency electromagnetic waves.

在雷达系统中,磁控管对于产生高频电磁波至关重要。

The research paper discusses advancements in magnetron efficiency for industrial applications.

这篇研究论文讨论了工业应用中磁控管效率的进展。

常见错误

❌ 错误:The magnetron is used for cooking in the oven.
✓ 正确:The magnetron is used for generating microwaves in the oven.

错误在于混淆了功能:磁控管产生微波,而不是直接用于烹饪;应明确其作为微波发生器的角色。

❌ 错误:I need to buy a new magnetron for my radar.
✓ 正确:I need to replace the magnetron in my radar system.

错误在于用词不准确:'buy a new magnetron' 可能暗示单独购买,但通常磁控管是设备的一部分,更常说 'replace' 表示更换。
