# 急需！要把一段中文翻譯成英文～

請知道怎麼翻譯以下那段文字的大大幫幫忙～感謝！！！

我們專題所使用的DES加密演算法為一種對稱式金鑰密碼系統，由於加密和解密的金鑰是相同的，所以為了資料的安全性，密鑰要定期的改變才行。首先我們先將DES加密演算法用MATLAB寫入程式並結合GUI平台加以呈現出來，並將其分成四個部份，分別為初始排列IP、子金鑰產生、F函數、終結排列FP，且對這四個部份做更詳細的分割，包括所需要用到的公式、查表以及計算DES的每個步驟，這樣就可以讓使用此教學平台的使用者能更輕易的學習到DES加密演算法。

Our topic uses the DES encryption calculating method is one kind of symmetrical expression gold key cryptographic system, because the encryption and decipher Jin Yue is the same, therefore for the material security, the key wants the regular change to be only then good. First we read in the first DES encryption calculating method with MATLAB the program and unify the GUI platform to present, and divides into it four parts, respectively be initial arranges IP, the interest key to have, the F function, the end to arrange FP, and makes a more detailed division to these four parts, including the formula which, the table look-up needs to use as well as calculate DES each step, like this may enable the user who uses this teaching platform the study DES encryption calculating method easily.
