雙極胸導聯(lián)心電圖是測定人體胸部特定部位與三個肢體之間的心電電位差，即探查電極放置于胸部六個特定點，參考電極分別接到三個肢體上。以CR、CL、CF表示。CR為胸部與右手之間的心電電位差，CL為胸部與左手之間的心電電位差，CF為胸部與左腳之間的心電電位差，其組合原理由下式來表達：CR＝Ucn－URCL＝Ucn－ULCF＝Ucn－UF其中Ucn為胸部電極V1～V6的心電電位。雙極胸導聯(lián)在臨床診斷上應用較少，這種導聯(lián)法的臨床意義還有待于醫(yī)務工作者探索和研究。臨床上常用的是單極胸導聯(lián)。胸部電極安放位置如圖1-1-14所示。轉載請注明醫(yī)學工程在線()，同時歡迎訪問醫(yī)學工程在線論壇(bbs.)與同行網友共同討論交流。醫(yī)學工程在線論壇是醫(yī)療器械維修及管理交流論壇，是醫(yī)院設備科、醫(yī)學工程科及其他醫(yī)學工程專業(yè)人員的交流平臺，提供醫(yī)學工程領域的資訊信息、技術交流、配件供求、人才招聘等綜合服務。</p><p> 把晶體二極管分類如下：1、點接觸型二極管點接觸型二極管是在鍺或硅材料的單晶片上壓觸一根金屬針后，再通過電流法而形成的。因此，其PN結的靜電容量小，適用于高頻電路。但是，與面結型相比較，點接觸型二極管正向特性和反向特性都差，因此，不能使用于大電流和整流。因為構造簡單，所以價格便宜。對于小信號的檢波、整流、調制、混頻和限幅等一般用途而言，它是應用范圍較廣的類型。2、鍵型二極管鍵型二極管是在鍺或硅的單晶片上熔接或銀的細絲而形成的。其特性介于點接觸型二極管和合金型二極管之間。與點接觸型相比較，雖然鍵型二極管的PN結電容量稍有增加，但正向特性特別優(yōu)良。多作開關用，有時也被應用于檢波和電源整流（不大于50mA）。在鍵型二極管中，熔接金絲的二極管有時被稱金鍵型，熔接銀絲的二極管有時被稱為銀鍵型。3、合金型二極管在N型鍺或硅的單晶片上，通過合金銦、鋁等金屬的方法制作PN結而形成的。正向電壓降小，適于大電流整流。因其PN結反向時靜電容量大，所以不適于高頻檢波和高頻整流。4、擴散型二極管在高溫的P型雜質氣體中，加熱N型鍺或硅的單晶片，使單晶片表面的一部變成P型，以此法PN結。因PN結正向電壓降小，適用于大電流整流。近。由于不便檢測，于是就直接更換了7812。更換后故障依舊。</p><div

此法適用于制造高靈敏度的變容二極管。8、外延型二極管用外延面長的過程制造PN結而形成的二極管。制造時需要非常高超的技術。因能隨意地控制雜質的不同濃度的分布，故適宜于制造高靈敏度的變容二極管。9、肖特基二極管基本原理是：在金屬（例如鉛）和半導體（N型硅片）的接觸面上，用已形成的肖特基來阻擋反向電壓。肖特基與PN結的整流作用原理有根本性的差異。其耐壓程度只有40V左右。其特長是：開關速度非?？欤悍聪蚧謴蜁r間trr特別地短。因此，能制作開關二極和低壓大電流整流二極管。二、根據用途分類1、檢波用二極管就原理而言，從輸入信號中取出調制信號是檢波，以整流電流的大?。?00mA）作為界線通常把輸出電流小于100mA的叫檢波。鍺材料點接觸型、工作頻率可達400MHz，正向壓降小，結電容小，檢波效率高，頻率特性好，為2AP型。類似點觸型那樣檢波用的二極管，除用于檢波外，還能夠用于限幅、削波、調制、混頻、開關等電路。也有為調頻檢波**的特性一致性好的兩只二極管組合件。2、整流用二極管就原理而言，從輸入交流中得到輸出的直流是整流。以整流電流的大?。?00mA）作為界線通常把輸出電流大于100mA的叫整流。面結型，工作頻率小于KHz。我無意中瞟了一眼萬用表的屏幕，且慢，怎么不是0Ω？而是45Ω。蘭州AESCULAPAxel300W冷光源主機芯片級維修</p><p

根據電解電容器容量大小，通常選用萬用表的R×10、R×100、R×1K擋進行測試判斷。紅、黑表筆分別接電容器的負極和正極（每次測試前，需將電容器放電），由表針的偏擺來判斷電容器質量。若表針迅速向右擺起，然后慢慢向左退回原位，一般來說電容器是好的。如果表針擺起后不再回轉，說明電容器已經擊穿。如果表針擺起后逐漸退回到某一位置停位，則說明電容器已經漏電。如果表針擺不起來，說明電容器電解質已經干涸推失去容量。有些漏電的電容器，用上述方法不易準確判斷出好壞。當電容器的耐壓值大于萬用表內電池電壓值時，根據電解電容器正向充電時漏電電流小，反向充電時漏電電流大的特點，可采用R×10K擋，對電容器進行反向充電，觀察表針停留處是否穩(wěn)定（即反向漏電電流是否恒定），由此判斷電容器質量，準確度較高。黑表筆接電容器的負極，紅表筆接電容器的正極，表針迅速擺起，然后逐漸退至某處停留不動，則說明電容器是好的，凡是表針在某一位置停留不穩(wěn)或停留后又逐漸慢慢向右移動的電容器已經漏電，不能繼續(xù)使用了。表針一般停留并穩(wěn)定在50－200K刻度范圍內。蘭州AESCULAPAxel300W冷光源主機芯片級維修</p><p
