2011鋁合金，銅是它的主要合金元素，加了點鉛和鉍，切削性能杠杠的，強度也很高，就是耐腐蝕性差點兒。適合做螺絲釘和需要良好切削性能的機械零件，挺常用的材料！

用友軟件年度結轉操作步驟 一、 在做年度結轉前要做好備份，備份步驟如下： 1、進入系統管理，點注冊， 2、注冊用戶名用admin，再點確定。 3、再點擊菜單欄中的“賬套”，下拉菜單中選擇“輸出” 4、選擇我們所要備份的賬套，選擇之后點確認。 5、稍后系統會出現如下畫面，如果電腦配置較低，系統360問答會有短暫的沒有響應，只要繼續等下去就可，系統在壓縮數據庫。 6、數據備份完成后，彈出如下對話框，我們再選擇自己所要保存數據的路徑即可。 7、選擇路徑時，一定要確定所選文件夾為打開狀態，只要雙擊要保存的文件夾，再點確認即可完成備份。 8、備份完成，如果要將數據拷貝到U盤，直接找到備份文件夾，復制到U盤即可。 二，完成數據備份后，進行建立新年度的年度賬。 1、 進入系統管理，點“系統”下拉菜單中的“注冊”；用戶名選擇要做賬套的賬套主管的名字，一般為操作員自己的名字；選擇要做的賬套；會計年度選擇上一年的年度。如果要做2006年的年度賬，就選2005年。選好后點確定 2、 在菜單欄中選年度賬，在下拉菜單中選“建立”， 3、 點確認，接著點是。 4、系統會出現假死機，用戶只要耐心等待即可，根據電腦性能不同，花的時間也不同。 4、 建立完成后，系統會彈出如下畫面，表示建表綠仍紀立成功。 三、 結轉上年數據 注：在用友軟件中，年度賬建立完成后，并不代表著直接可以進行下一年度的賬務操作，此時系統只結轉了會計科目，客戶檔落似案，存貨檔案等基礎檔案，沒有任何上年數據。上年度數據的結轉需要我們進一步的操作。 1、 進入系統管理，點“系統”下拉菜單中的“注冊”；用戶名選擇要做賬套的賬套主管的名字，一般為操作員自己的名字；選擇要做的賬套；會計年度選擇本年的年度。如果要結轉2005年的年度期末數據，此時要選因粉員子2006年。選好后點確定 2、 在菜單欄中選年度賬，在下拉菜單中選“結轉上年數據”， 注：因為版本的不一樣，此時選擇也不一樣， 1） 如果是財務通基礎版，直接選擇總賬系統結轉即可； 2） 如果是財務通版準版或者套裝版，并且本賬套使用了固引互非雙跑定資產、工資模塊。先要結轉固定資產和工資系統，兩者沒有先后順序；最后結轉總賬系統。 3） 如果是TONG2005的版本，并且使用了購銷存，就按照如圖所示，按順序從上到下結轉。 4） 因為結轉都比較簡單，在此我們只以結轉總賬系統為例加以說明。 3、 在結轉上年數據中選擇總賬系統結轉， 4、 點確認 5、 確認后系統彈出如下對話框，如果客戶要進行賬齡分析，并且每個月進行了賬齡兩清的操作，就選擇明細方式結轉；如果不需要賬齡分析，選余額方式。 注：一般建議選擇余額方式結轉，明細方式結轉如果操作不當容易出錯！ 6、 經過結轉后，系統會彈出一個結轉報告，提示你正確的結轉科目和錯誤的結轉科目，如果有錯誤的，要查清楚原因。 7、 如果沒有問題，稍等就可以進行用下年度的時間進去進行新年度的賬務操作了。 8、 新的年度的報表，只要重新把原來的報表復制一份，在報表系統打開，進行賬套初始后就可以重新計算了。

邏輯板有問題，這個修起來要換板的哦，大概費用在500-700之間。

謝謝工程師fly_phoenix，明白點了。兩種都為相同的合金基體，2024 t3 clad sheet只是外層包了一層純鋁，對么？我是搞膠粘劑的，不同的表層粘接效果不同。不好意思，再請教，以上數據來自？（我是“金屬”門外漢了）
