风扇叶片

In this paper,a numerical method is used to investigate the effects of a winglet attached to an axial fan on the performance.

本文采用数值方法研究了叶片端导叶对轴流风扇性能的影响。

The more the number of the blades, the costlier is the fan.

越多的叶片，昂贵的风扇。

By computational fluid dynamics technique, the aerodynamic performances of different types of twisted blades are numerically investigated in the design and on the off-design operating conditions. The aerodynamic performances of the enlarged model fans in self-stimulated domain are compared with that of the micro-scale fans in non-self-stimulated domain.

通过计算流体动力学技术，对利用该方法所设计的各种形式扭叶片的气动性能及其变工况时的气动特点进行了数值研究，并比较了工作于自模区与非自模区风扇的气动性能差异。

The noise may come from the hard disk on its own vibration, this time on the issue is not only annoying noise that simple, but involves the safety of the hard disk.

而震动噪声一般是由于风扇叶不平衡，叶片在轴上松动以及轴承间隙过大造成的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
