電腦不僅能幫助我們快速完成重復(fù)性的工作，而且提供了一種休閑娛樂(lè)的方式。學(xué)電腦能夠快速入門是每個(gè)新手夢(mèng)寐以求的事情，但是不是每個(gè)人都能快速入門的。但是如果定制好合理計(jì)劃，循序漸進(jìn)，就會(huì)收到非常好的效果。

電腦的組成

一個(gè)完整的電腦由軟件和硬件組成。硬件主要包括我們常見(jiàn)的鼠標(biāo)，鍵盤，顯示器，主機(jī)和各種儲(chǔ)存介質(zhì)，電腦的硬件如同人的軀干和四肢；而軟件如同人的大腦和神經(jīng)系統(tǒng)，軟件在硬件的基礎(chǔ)上才能工作。

基礎(chǔ)入門

啟動(dòng)電腦

電腦啟動(dòng)就是我們常說(shuō)的“開(kāi)機(jī)”，也是啟動(dòng)操作系統(tǒng)的過(guò)程。開(kāi)機(jī)具有一定的順序：

1、打開(kāi)顯示器

2、打開(kāi)主機(jī)

3、開(kāi)機(jī)自檢

4、啟動(dòng)成功

通過(guò)上述步驟啟動(dòng)電腦，叫做冷啟動(dòng)，是常規(guī)的開(kāi)機(jī)步驟。此外，在特殊情況下，我們還可以通過(guò)下面兩種方式啟動(dòng)電腦。

熱啟動(dòng)：是指電腦處于開(kāi)機(jī)的狀態(tài)下，通過(guò)【開(kāi)始】菜單中的【重新啟動(dòng)|】命令對(duì)電腦進(jìn)行重新啟動(dòng)。

復(fù)位啟動(dòng)：當(dāng)電腦在運(yùn)行過(guò)程中出現(xiàn)異常而不能運(yùn)行，且采用熱啟動(dòng)失效時(shí)，可以采用復(fù)位啟動(dòng)方式重啟電腦，方法是按下主機(jī)箱上的【復(fù)位】按鈕即可。

關(guān)閉電腦

使用完電腦后，需要將其關(guān)閉。電腦的關(guān)機(jī)順序與開(kāi)機(jī)順序正好相反。即先關(guān)主機(jī)電源，然后逐一關(guān)閉外部設(shè)備的電源。遵循正確的開(kāi)關(guān)機(jī)順序可延長(zhǎng)電腦的使用壽命。

正確的關(guān)機(jī)方法為：在系統(tǒng)桌面上單擊【開(kāi)始】按鈕，在彈出的【開(kāi)始】菜單中單擊【關(guān)機(jī)】按鈕，電腦將停止所有程序并退出操作系統(tǒng)，接著系統(tǒng)將自動(dòng)斷開(kāi)主機(jī)電源，然后再依次關(guān)閉顯示器、音箱等外接設(shè)備即可。

如何使用鍵盤

鍵盤是用于操作計(jì)算機(jī)設(shè)備運(yùn)行的一種指令和數(shù)據(jù)輸入裝置，也指經(jīng)過(guò)系統(tǒng)安排操作一臺(tái)機(jī)器或設(shè)備的一組功能鍵（如打字機(jī)、電腦鍵盤）。

電腦鍵盤由功能鍵區(qū)、主鍵區(qū)、編輯鍵區(qū)，數(shù)字鍵區(qū)和小鍵盤區(qū)5個(gè)區(qū)組成。其中常用操作打字是在主鍵區(qū)完成的。

鍵盤是最常用也是最主要的輸入設(shè)備，通過(guò)鍵盤可以將英文字母、漢字、數(shù)字、標(biāo)點(diǎn)符號(hào)等輸入到計(jì)算機(jī)中，從而向計(jì)算機(jī)發(fā)出命令、輸入數(shù)據(jù)等。

如何使用鼠標(biāo)

鼠標(biāo)，是計(jì)算機(jī)的一種外接輸入設(shè)備，也是計(jì)算機(jī)顯示系統(tǒng)縱橫坐標(biāo)定位的指示器，因形似老鼠而得名（港臺(tái)作滑鼠）。其標(biāo)準(zhǔn)的稱呼應(yīng)該是“鼠標(biāo)器”，英文名“Mouse”。鼠標(biāo)的使用是為了使計(jì)算機(jī)的操作更加簡(jiǎn)便快捷，來(lái)代替鍵盤那繁瑣的指令。

一般的鼠標(biāo)上有左鍵，右鍵和滑輪三個(gè)部分。

計(jì)算機(jī)的儲(chǔ)存介質(zhì)

計(jì)算機(jī)的儲(chǔ)存介質(zhì)有：硬盤、U盤、光盤和軟盤等。

硬盤

電腦硬盤是計(jì)算機(jī)最主要的存儲(chǔ)設(shè)備，硬盤一般分為固態(tài)硬盤（SSD）和機(jī)械硬盤（HDD）兩種。固態(tài)硬盤讀寫速度更快，但存儲(chǔ)容量較小，機(jī)械硬盤存儲(chǔ)容量較大但同容量大小，固態(tài)硬盤價(jià)格也更昂貴。

U盤

U盤是USB(USB flash disk)盤的簡(jiǎn)稱，據(jù)諧音也稱“優(yōu)盤”。U盤是閃存的一種，故有時(shí)也稱作閃盤。U盤與硬盤的最大不同是，它不需物理驅(qū)動(dòng)器，即插即用，且其存儲(chǔ)容量遠(yuǎn)超過(guò)軟盤，極便于攜帶。

軟件操作

電腦軟件（Computer Software）是指計(jì)算機(jī)系統(tǒng)中的程序及其文檔。一般來(lái)講軟件被劃分為系統(tǒng)軟件、應(yīng)用軟件，系統(tǒng)軟件為計(jì)算機(jī)使用提供最基本的功能，可分為操作系統(tǒng)和支撐軟件，其中操作系統(tǒng)是最基本的軟件，常見(jiàn)的操作系統(tǒng)包括為微軟的Windows系統(tǒng)。

軟件的基礎(chǔ)操作

軟件的使用包括軟件的下載、安裝和卸載：

軟件的下載

1、瀏覽器下載

2、軟件官網(wǎng)下載

3、電腦管家或360軟件管家等下載軟件（下圖為360軟件管家）

軟件安裝

第一種就是你下載下來(lái)的是.exe文件的應(yīng)用程序，這種程序一般都是安裝包，就是你雙擊之后，會(huì)進(jìn)入安裝界面；第二種就是不需要安裝的，你下載下來(lái)的是一個(gè)壓縮文件，你只需要解壓就可以使用。

電腦軟件安裝過(guò)程中特別要逐一擇安裝設(shè)置（安裝盤位）的選擇、流氓軟件選項(xiàng)勾選等。

軟件的卸載

控制面板—程序和功能—找到要卸載的軟件—右擊卸載

軟件的啟動(dòng)

電腦軟件的啟動(dòng)方法一般有雙擊，右擊-打開(kāi)或從開(kāi)始菜單單擊打開(kāi)

1、一般安裝軟件后會(huì)在桌面創(chuàng)建快捷方式，直接打開(kāi)。

2、若桌面沒(méi)有快捷方式，可以在電腦左下角的“開(kāi)始”—“程序”里面打開(kāi)。

3、若“程序”里面也沒(méi)有，可以打開(kāi)軟件的安裝位置打開(kāi)。

說(shuō)明：第三種方法是按默認(rèn)的安裝路徑找到的軟件安裝文件夾打開(kāi)程序的，實(shí)際情況可以根據(jù)軟件的具體安裝路徑選擇打開(kāi)。

應(yīng)用軟件的操作

文件操作包括如何操作打開(kāi)，關(guān)閉、刪除、移動(dòng)、重命名和編輯文件

文件打開(kāi)

文件打開(kāi)方式見(jiàn)“如何啟動(dòng)軟件”部分

常見(jiàn)不同后綴、格式文件打開(kāi)方法：

.txt .doc .docx .obt 這些格式可以用微軟的office打開(kāi)，或者用wps打開(kāi)。

mp3格式文件可以使用使用電腦自帶的Media Player播放器或者其他的音樂(lè)播放器。

mp4、mpg. mpeg.等文件可以使用電腦自帶的電影和電視功能或者其他視頻軟件打開(kāi)。

文件關(guān)閉

一般軟件點(diǎn)擊右上角的“×”，再點(diǎn)擊“確認(rèn)”，即可關(guān)閉文件

文件刪除

1、選中文件-右擊-刪除

2、選中文件-按“delete”鍵，即刻刪除

文件移動(dòng)

方法一：長(zhǎng)按鼠標(biāo)左鍵選中并拖動(dòng)鼠標(biāo)移動(dòng)文件到想要的地方

方法二：右擊鼠標(biāo)—剪切-打開(kāi)需要移動(dòng)的地方-右擊粘貼

文件重命名

方法一：選中文件—右擊—重命名

方法二：鼠標(biāo)左擊—鍵盤F2，即可進(jìn)行重命名

文件管理基礎(chǔ)知識(shí)

硬盤分區(qū)

電腦中的文件都存放在硬盤中，而新買回來(lái)的硬盤相當(dāng)于一張白紙 ，為了能夠更好地使用它，需要在，白紙上劃分出若干小塊。然后再打上格子。硬盤分區(qū)就是這個(gè)道理，在安裝操作系統(tǒng)之前，需要進(jìn)行硬盤分區(qū)和格式化，然后才能投入使用。對(duì)硬盤進(jìn)行分區(qū)后，各個(gè)分區(qū)獨(dú)立使用，互不影響。在操作系統(tǒng)中每個(gè)分區(qū)都用一個(gè)盤符表示，如本地磁盤（C）、本地磁盤（D）等。

存儲(chǔ)路徑

文件的存儲(chǔ)路徑，就是文件在電腦硬盤中的存儲(chǔ)位置，由硬盤分區(qū)、文件夾和子文件夾構(gòu)成。其中硬盤分區(qū)的盤符為路徑的第一項(xiàng)，是第一級(jí)目錄，也叫做根目錄，后面緊跟冒號(hào)和斜線（：/），文件夾和子文件夾中間則以斜線（/）隔開(kāi)。

如何使用瀏覽器

主要介紹如何使用瀏覽器（以及搜索引擎）查找資料（以今日頭條為例）。

1、首先在瀏覽器中搜索引擎輸入今日頭條，然后點(diǎn)擊推送的今日頭條進(jìn)入官方頁(yè)面：

2、然后就進(jìn)入搜索引擎所在網(wǎng)頁(yè)，這樣才能進(jìn)行搜索：

3、之后在搜索欄中輸入搜索內(nèi)容，可以是詞語(yǔ)、短語(yǔ)也可以是句子：

4、最后點(diǎn)擊搜索框后方的放大鏡進(jìn)行搜索：

5、然后就可以得到想要的信息了：

電腦的日常維護(hù)

日常注意事項(xiàng)

電腦的五大要害：靜電、灰塵、水、震蕩、病毒是電腦的五大要害

1、防靜電：防止靜電損壞電腦各部分電子原件，處理辦法是將電腦機(jī)箱外殼接地，盡量使用三腳電源插頭。

2、防塵：防止灰塵進(jìn)入電腦機(jī)箱內(nèi)，使用時(shí)保持環(huán)境清潔，并定期清理電腦主機(jī)內(nèi)的灰塵。

3、防水：防止液體進(jìn)入電腦的任何部分，保持室內(nèi)通風(fēng)。不要將電腦放在濕度較大的房間使用。

4、防震：在使用的過(guò)程要防止對(duì)電腦的震蕩，應(yīng)將電腦平穩(wěn)放置在電腦桌上，以防不小心摔落等

5、防病毒：病毒是電腦的一大要害，在日常使用中要防止病毒的進(jìn)入，需要給電腦安裝防病毒軟件，并經(jīng)常更新病毒庫(kù)，經(jīng)常給電腦殺毒。

顯示器維護(hù)

液晶顯示器最大的禁忌在于觸摸液晶面板。液晶面板表面有專門的涂層，這層涂層可以防止反光，增加觀看效果。而很多用戶不知道這點(diǎn)，總是習(xí)慣于用手去摸液晶屏幕，殊不知人手上有一定的腐蝕性油脂，會(huì)輕微的腐蝕面板的涂層，時(shí)間長(zhǎng)了會(huì)造成面板永久性的損害。這種被損壞的面板在使用中會(huì)有斑駁陸離的感覺(jué)。另外，有些人喜歡用手去壓面板，覺(jué)得很有意思。這絕對(duì)是個(gè)惡劣的習(xí)慣，這樣做會(huì)導(dǎo)致壞點(diǎn)和暗斑，這可是永久性的損害，絕不可修復(fù)的！

主機(jī)維護(hù)

在電腦運(yùn)行過(guò)程中，機(jī)器的各種設(shè)備不要隨便移動(dòng)，不要插拔各種接口卡，也不要裝卸外部設(shè)備和主機(jī)之間的信號(hào)電纜。如果需要作上述改動(dòng)的話，則必須在關(guān)機(jī)且斷開(kāi)電源線的情況下進(jìn)行。

不要頻繁地開(kāi)關(guān)機(jī)器。關(guān)機(jī)后立即加電會(huì)使電源裝置產(chǎn)生突發(fā)的大沖擊電流，造成電源裝置中的器件被損壞，也有可能造成硬盤驅(qū)動(dòng)突然加速，使盤片被磁頭劃傷。因此，這里我們建議如果要重新啟動(dòng)機(jī)器，則應(yīng)該在關(guān)閉機(jī)器后等待10秒鐘以上。在一般情況下不要擅自打開(kāi)機(jī)箱，如果機(jī)器出現(xiàn)異常情況，應(yīng)該及時(shí)上報(bào)。

數(shù)據(jù)存放在不同分區(qū)，減少磁頭對(duì)某一扇區(qū)的經(jīng)常讀寫，導(dǎo)致這一扇區(qū)的損壞。 建議你使用不同的媒介定期對(duì)你的重要數(shù)據(jù)進(jìn)行備份，并存放在不同的地方。一個(gè)文件可以在備份盤上放一份，可以打印一份，可以刻錄成光盤。

鍵盤、鼠標(biāo)的日常維護(hù)

（1）保保持清潔 　過(guò)多的灰塵會(huì)給電路正常工作帶來(lái)困難，有時(shí)造成誤操作，雜質(zhì)落入鍵位的縫隙中會(huì)卡住按鍵，甚至造成短路。我們?cè)谇鍧嶆I盤時(shí)，可用柔軟干凈的濕布來(lái)擦拭，按鍵縫隙間的污漬可用棉簽清潔，不要用醫(yī)用消毒酒精，以免對(duì)塑料部件產(chǎn)生不良影響。清潔鍵盤時(shí)一定要在關(guān)機(jī)狀態(tài)下進(jìn)行，濕布不宜過(guò)濕，以免鍵盤內(nèi)部進(jìn)水產(chǎn)生短路。

(2)不將液體灑到鍵盤上 　一旦液體灑到鍵盤上，會(huì)造成接觸不良、腐蝕電路造成短路等故障，損壞鍵盤。所以我們一般不要邊喝茶邊坐在電腦前,這樣一不小心茶可能就灑在鍵盤上.

電腦病毒防護(hù)

電腦一旦感染了病毒，就會(huì)出現(xiàn)很多癥狀。導(dǎo)致系統(tǒng)性能的下降，影響用戶的使用，甚至造成災(zāi)難性的后果。電腦在日常的使用過(guò)程中要定期進(jìn)行病毒查殺，防患于未然。常用的電腦殺毒軟件有360，金山毒霸和電腦管家等等。以金山毒霸為例介紹電腦殺毒的過(guò)程。

1、打開(kāi)程序主界面

2、選擇殺毒方式

3、開(kāi)始?xì)⒍?。程序?qū)Υ疟P內(nèi)容自動(dòng)進(jìn)行掃描，如果檢測(cè)到病毒會(huì)自動(dòng)進(jìn)行清除，并將結(jié)果顯示在掃描欄中。

4、除此之外還可以對(duì)特點(diǎn)的盤進(jìn)行殺毒。

二階常系數(shù)齊次線性微分方程解法

一般形式:y”+py’+qy=0,特征方程r2+pr+q=0

特征方程r2+pr+q=0的兩根為r1,r2 微分方程y”+py’+qy=0的通解

兩個(gè)不相等的實(shí)根r1,r2 y=C1er1x+C2er2x

兩個(gè)相等的實(shí)根r1=r2 y=(C1+C2x)er1x

一對(duì)共軛復(fù)根r1=α+iβ,r2=α-iβ y=eαx(C1cosβx+C2sinβx)

2.1.二階常系數(shù)非齊次線性微分方程解法

一般形式: y”+py’+qy=f(x)

先求y”+py’+qy=0的通解y0(x),再求y”+py’+qy=f(x)的一個(gè)特解y*(x)

則y(x)=y0(x)+y*(x)即為微分方程y”+py’+qy=f(x)的通解

求y”+py’+qy=f(x)特解的方法:

① f(x)=Pm(x)eλx型

令y*=xkQm(x)eλx［k按λ不是特征方程的根,是特征方程的單根或特征方程的重根依次取0,1或2］再代入原方程,確定Qm(x)的m+1個(gè)系數(shù)

03

2.2.②f(x)=eλx［Pｌ(x)cosωx+Pn(x)sinωx］型

令y*=xkeλx［Qm(x)cosωx+Rm(x)sinωx］［m=max﹛ｌ,n﹜,k按λ+iω不是特征方程的根或是特征方程的單根依次取0或1］再代入原方程,分別確定Qm(x)和Rm(x)的m+1個(gè)系數(shù)

04

有關(guān)微分方程的題目有很多，不可能一一列舉出來(lái)，但我們可以掌握方法，開(kāi)拓思維，這樣我們的高數(shù)才會(huì)得以提高。

4、薄板焊接時(shí)焊槍可向焊縫一側(cè)傾斜，以減小熔深避免熔穿母材。

5、室外施工風(fēng)速達(dá)1.5ms應(yīng)采取防風(fēng)措施，防止產(chǎn)生氣孔缺陷。
