摘要:電壓監測儀的校驗工作量大、 效率和精度低， 為保證電壓監測儀性能指標， 研制了一種對單相電壓監測統計儀進行精度、 靈敏度、 諧波、 時間試驗的校驗裝置。裝置以高速單片機為核心， 利用豐富的P C機資源、 融合F P G A 技術、 點陣圖形液晶等技術， 實現監測儀誤差校驗過程的自動控制、微機數據管理、 程控操作、 故障保護。實驗結果表明裝置綜合誤差為0 . 1 級， 輸出電壓失真度小于0 . 5 ， 系 統運行準確、 數據傳輸可靠、 操作方便及功能完善。

he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.

This algorithm is to count the dark colored pixels in the input image. This can be used in goods sorting like rice, paddy etc... in paddy or rice or other goods or products to sort out the bad or defect one we can use this algorithm. I had done this for my Masters Degree as a small part and now i am releasing for you. rajesh.f, Kanayakumari district, India. contact me: rajesh1983jan10@yahoo.com

找一個最小的自然數，使它等于不同的兩組三個自然數的三次冪之和，即找最小的x，使得：x=a*a*a+b*b*b+c*c*c = d*d*d+e*e*e+f*f*f 其中，a,b,c,d,e,f都是自然數,a<=b<=c, d<=e<=f [a,b,c]!=[d,e,f] 進一步，是否還存在另外一個自然數滿足上述條件，可能的話請輸出其結果
