1·Averaging method of neighborhood and medium filtering method are used to effectively overcome thermionic noise as result of courses of image transferring, gathering and quantization and so on.
对由于图像采集、传输、量化过程中产生的热电子噪声，利用了邻域平均和加权中值滤波方法来有效地减小。
2·We monitored with American thermionic air automatic monitoring instrument synchronistically, and found the results of the two method were different obviously.
同步用美国热电子大气自动监测车载系统监测，则两者差异较大。
3·The thermionic emission cooling employing hetero structure is a high efficient cooling method.
基于异质结结构热电子发射的热电制冷，是近年来提出的一种高效制冷方法。
