光學(xué)設(shè)計(jì)軟件zemax源碼: This DLL models an nular aspheric surface as described in: "Annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

zemax源碼: This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.

RSA公鑰加密算法基于大整數(shù)因式分解困難這樣的事實(shí)。 選擇兩個(gè)素?cái)?shù),p,q。(一般p,q選擇很大的數(shù)) 然后計(jì)算 z=p*q f=(p-1)(q-1) 選擇一個(gè)n,使gcd(n,f)=1(gcd代表greatest common divider,一般n也選擇一個(gè)素?cái)?shù)), n和z就作為公鑰。 選擇一個(gè)s,0<s<f,滿足n*s % f=1,s就作為私鑰。

使用面向?qū)ο蠓椒ㄍ瓿伞翱焖倨磳憴z查程序”的分析、設(shè)計(jì)和實(shí)現(xiàn)過程。快速拼寫檢查程序基本要求說明如下: 1.進(jìn)行拼寫檢查的文件以文本文件形式存儲(chǔ)于外存上;2.只檢查文件中英文單詞的拼寫錯(cuò)誤;3.單詞是用字母(a…z或A…Z)定義,任一非字母字符作為分隔符;4.判斷單詞拼寫正誤的依據(jù)是詞典,詞典以文本文件形式存放于外存上;5.詞典文件第1行為詞典的名稱,以后每一行存放一個(gè)單詞;6.輸出結(jié)果以文本文件形式存儲(chǔ),其格式為:第1行:被拼寫檢查的文件名 + 詞典名 第2行后的每一行: 出錯(cuò)單詞 位于第x行7.設(shè)計(jì)一個(gè)合理的GUI,注意GUI界面類與功能類的關(guān)系應(yīng)比較松散。
