障板也不错。
障板一般安装在传感器与噪声源之间，用来屏蔽噪声对传感器的影响；
Basically, the baffle is a structure, placed between an unwanted signal or noise source and a sensor, to shield the sensor from the unwanted source.
障板对来自抽气方向的热辐射的屏蔽效果。将直接影响泵的各项抽气性能。
The shielding function of the baffle to the heat radiation coming from pumping direction will directly effect on the various pumping performance.
本文提出了一种简便计算置于无限大障板上裂纹薄板水中振动频率和模态辐射效率的计算方法。
A simple method for computing the modal vibration frequencies and sound radiation efficiencies of a thin cracked baffled plate in water is described.
当设计一个扬声器时，进行自由场测量以观察喇叭的指向性和障板形状对于极性响应的影响是非常重要的。
When designing a loudspeaker it is essential to perform free-space measurements to see the effects of driver directivity and baffle shape on the important polar response.
那末务求不宽大，能够取舍有油泵，加上一些防油净化措施，如加冷阱、障板、挡油阱等，也能达成肮脏真空务求。
Then the view is not large, to choose a pump, plus some oil purification measures, such as the Canadian cold trap, baffle, retaining the oil wells, but also in order to reach a dirty vacuum.
