In the precision detection of a millimeter wave, the encounter of the detector and the objects can not be forecasted totally because of a lot of noise and disturbance existing in the complex battlefield, it will cause fantasticality and distortion of the echo retaked by the detector, and the stably of the echo become bad, as a result, it will reflect the result of the detection, so it is necessary to filter the echo retaked by detector.

在彈載毫米波精確探測系統(tǒng)中，由于復雜多變的戰(zhàn)場環(huán)境中存在大量的干擾及噪聲，探測器與目標的交會姿態(tài)不能完全預測，造成探測器獲取目標回波產(chǎn)生奇異和變形，回波特征的穩(wěn)定性變差精品一区二区三区无码毛片，從而影響了目標的探測和識別，因此對探測器的回波進行有效的濾波處理是十分必要的野狼精品无码视频在线。

The main research of this paper is about the pre-amplifier used in thenuclear radiation examination, in view of gamma ray's characteristic affectionon the matter, the electric circuit's noise and disturbance are restrainedbased on the nuclear electron theory.

本文主要研究用于核輻射檢測的前置放大器狂野欧美性交大全，針對γ射線與物質(zhì)相互作用的特點，運用核電子學的理論解決電路中的噪聲和干擾問題久久网亚洲精品。

To eliminate the disturbance of the noise (particularly the pulse noise and salt-and-pepper noise influence which causes by equipment and transmission) in image processing, a smooth operation is needed. In this paper we have analyzed several smooth operation methods and improve median filter method by a directional way to reduce the detail loss of smoothing process.

為在圖像處理過程中去除噪聲的干擾（尤其是由設備和傳輸引起的脈沖噪聲和椒鹽噪聲的影響）直接免费在线观看的黄网站，首先對圖像進行平滑操作，本文對常用的幾種平滑濾波方法進行了分析免费一级特黄A毛大片看看，選擇使用中值濾波方法三级A片视频，并使用邊緣的方向信息對其進行了改進，以減少平滑過程中的細節(jié)損失91popny丨丝袜。
