The cyclone brought misery to thousands of people .. 旋风给成千上万的人带来苦难。
Middle-latitude cyclones originate at the polar front . 中纬度地区的气旋发源于极锋。
A cyclone in the tropics is caused by a smaller area of low pressure . 热带暴风是由小面积低压引起的。
The principal objective in designing cyclones is to create a vortex . 设计旋风除尘器的主要目的在于造成涡旋运动。
This control requires knowledge of attrition kinetics and cyclone effectiveness . 这种控制要求颗粒磨损动力学和旋风分离器效率的知识。
A region of low pressure with roughly concentric isobars is known technically as a cyclone . 具有大致同心的等压线的低压区在技术上称为气旋。
By using cyclone separators to return the entrained solids, even higher gas velocities can be used . 当采用丁旋风分离器来使夹带固体颗粒返回时，还可用更高的气速。
To avoid rapid loss of solids, cyclones and electrostatic precipitators should have a very high collecting efficiency . 为了避免固体很快损失，旋风分离器和电器除尘器应当有很高的捕集效率。
Vortex injection provides a form of swirl or cyclone combustion for a rocket engine similar to systems often employed in industrial furnaces . 涡流喷射在火箭发动机中产生一种涡流或旋涡形式的燃烧，与工业炉中常采用的系统相似。
