circular ring

基本解釋

The method of counting for circular ring objects in frequency domain is proposed.
研究了用頻域法實現(xiàn)圓環(huán)形目標(biāo)物計數(shù)的方法。
But the arithmetic product operation is needed to determine a pixel belonging to which circular ring, which consumes much time.
但由于確定各像素點屬于哪一個圓環(huán)需要進行復(fù)雜的乘積運算，耗費了大量時間。
The flexural vibration of a circular ring that is of axis symmetry is analyzed and calculated, the solid frequency expression of the flexural vibration is obtained.
對一類軸對稱圓環(huán)的面內(nèi)彎曲振動進行了分析計算，給出了圓環(huán)面內(nèi)彎曲振動固有頻率表達式。

There is no way that you could irradiate a crystal of nickel with a single beam of x-rays and get that circular ring pattern if the electron beam were behaving as a particle beam only.
沒有什么其他的途徑,可以讓鎳晶體發(fā)射,單束X光來,繼而得到環(huán)狀圖案,如果電子束,是以粒子束形式出現(xiàn)的。
