On the basis of analyzing the reason of bad aluminum foil crosscut effect , this text applies the geometry characteristic of the uniparted hyperboloid to the crosscut mechanism of moving aluminum foil , and confirmed the type line of rotating knife edge , thus a kind of rational method for movement aluminum foil crosscut had been drawn 在分析鋁箔橫切效果不佳原因的基礎上,把單葉雙曲面的幾何特性應用于移動鋁箔的橫切機構之中,并確定了轉刀刀刃的型線,從而得出一種移動鋁箔橫切的合理方法。

The system is on the basis of fourier optics . by using knife edge as object , cmos sensor as device for image reception , we get edge spread function from the image histogram and use differential operation and fft to achieve mtf of the lens , then its image quality is obtained 本系統以傅立葉光學為依據,以刀口為目標物,以cmos為圖像接收器件,采用獨特的算法,從刀口圖像的灰度直方圖中獲得其刀口邊緣函數,經微分和fft運算,得到待測鏡頭的mtf ,從而得知其成像品質。

It still works well when the mulched straw is more then lot / ha . ( 3 ) an experiment was conducted on a self - made testing equipment to investigate the chopping properties of wheat straw under different conditions . on the basis of testing results , main cutting curves of wheat straw were given under different cutting speeds of rotary blade , with different straw lengths , different moisture contents , different cutting position , different thick of knife edge , with and without shear bar ( 3 )為了研究帶狀粉碎防堵裝置對麥秸的切碎效果,在特制的實驗臺上,應用了虛擬儀器測試技術對不同處理的麥稈進行了切斷試驗,得到了在不同切割速度下對不同長度、不同含水率的麥稈、麥稈的不同切割部位以及有定刀和無定刀情況下的切斷率,為麥秸粉碎裝置的設計提供了依據。

By using knife edge as object , and cmos sensor as device for image analyzing , we get edge spread function from the image and use differential operation and fft to obtain modulation transfer function of the lens , then its image quality is known 以刀口作為目標物,以cmos作為圖像分析器件,從圖像中獲取刀口函數,經微分和fft運算,得到成像鏡頭的mtf (調制傳遞函數) ,從而得知其成像品質。
