22、akegreatimprovement.Thesameonlypartymembers一、一、判斷題1.傳感器標(biāo)定時(shí)，標(biāo)準(zhǔn)器應(yīng)有足夠的精度，其允許的基本誤差不應(yīng)超過被校傳感器允許基本誤差的13～15，并具有計(jì)量部門周期檢定的合格證書。X2.系統(tǒng)誤差是有規(guī)律性的，因此可以通過實(shí)驗(yàn)的方法或引入修正值的方法計(jì)算修正，也可以重新調(diào)整測量儀表的有關(guān)部件予以消除。3.存在隨機(jī)誤差的測量結(jié)果中，雖然單個(gè)測量值誤差的出現(xiàn)是隨機(jī)的，既不能用實(shí)驗(yàn)的方法消除

23、，也不能修正，但是就誤差的整體而言，多數(shù)都服從正態(tài)分布規(guī)律。3.傳感器所能測量的最大被測量（輸入量）的數(shù)值稱為測量上限，最小被測量稱為測量下限，上限與下限之間的區(qū)間，則稱為測量范圍。傳感器所能測量的最大被測量（輸入量）的數(shù)值稱為測量上限，最小被測量稱為測量下限，上限與下限之間的差值，則稱為量程。檢測技術(shù)是以研究自動(dòng)檢測系統(tǒng)中的信息提取、信息轉(zhuǎn)換及信息處理的理論和技術(shù)為主要內(nèi)容的一門應(yīng)用技術(shù)學(xué)科。4.對于數(shù)字儀表而言，指示數(shù)字的最后一位數(shù)

24、字所代表的值就是它的分辨力。當(dāng)被測量的變化小于分辨力時(shí)，儀表的最后一位數(shù)字保持不變。5.為了減少讀數(shù)誤差。讀數(shù)時(shí)要正視量具的讀數(shù)裝置，不要造成斜視誤差。測量同一個(gè)點(diǎn)有2～3個(gè)接近的數(shù)值時(shí)，應(yīng)取算術(shù)平均值作為測量結(jié)果。6.靈敏度是傳感器在穩(wěn)態(tài)下輸入（出）增量與輸出增量的比值。X7.莫爾條紋的作用是能連續(xù)實(shí)現(xiàn)變倍并在很大程度上消除由于刻線不均勻引起的誤差。8.光電池是利用內(nèi)光電效應(yīng)制成的光電元器件。X9.一般可用霍爾傳感器測量磁場強(qiáng)度、電流

25、、角位移、功率、轉(zhuǎn)速、開關(guān)信號(hào)等參數(shù)。10.原始的壓電陶瓷是一個(gè)非壓電體，不具有壓電效應(yīng)。為了使壓電陶瓷具有壓電效應(yīng)，就必須進(jìn)行極化處理。11.互感傳感器本身就是變壓器，有一次繞組和二次繞組。一次側(cè)接入激勵(lì)電源后，二次側(cè)將因互感而產(chǎn)生電壓輸出。當(dāng)繞組間互感隨被測量變化時(shí)，輸出電壓將產(chǎn)生相應(yīng)的變化。12.鎳鉻—考銅電偶的分度號(hào)為K。13.變面積式電容傳感器的輸出特性是非線性的，這一類傳感器多用于檢測直線位移、角位移、尺寸等參量。14.壓電

26、效應(yīng)即在電介質(zhì)的極化方向施加交變電場，它會(huì)產(chǎn)生機(jī)械變形。當(dāng)去掉外加電場，電介質(zhì)變形隨之消失的現(xiàn)象。15.常用的接近開關(guān)有電渦流式、電容式、磁性干簧開關(guān)、霍爾式、光電式、微波式、超聲波式等。16.脈沖細(xì)分技術(shù)能在不增加脈沖細(xì)分技術(shù)能在不增加光柵刻線數(shù)及價(jià)格的情況下提高光柵的分辨力。20.電渦流接近開關(guān)可以利用電渦流效應(yīng)檢測出塑料零件的靠近程度。17.10分度的游標(biāo)卡尺的讀數(shù)可精確到0.1mm。20分度的游標(biāo)卡尺的讀數(shù)可精確到0.05mm。

27、50分度的游標(biāo)卡尺可精確到0.02mm?！?8.石英晶體的壓電系數(shù)比壓電陶瓷的大得多，所以采用石英晶一般體采用石英晶體制作標(biāo)準(zhǔn)力傳感器。19.采用高分子壓電薄膜振動(dòng)感應(yīng)片，可制成玻璃破碎報(bào)警裝置。20.由于光纖傳感器是利用光波傳輸信息，而光纖又是電絕緣、耐腐蝕的傳輸媒質(zhì)，并且安全可靠，這使它可以方便有效地用于各種大型機(jī)電，石油化工、礦井等強(qiáng)電磁干擾和易燃易爆等惡劣環(huán)境中。21.電位器式位移傳感器結(jié)構(gòu)簡單、價(jià)格低廉，輸出信號(hào)大，一般不需放

28、大，動(dòng)態(tài)響應(yīng)好。22.傳感型光纖式傳感器利用外界因素改變光纖中光的特征參量，從而對外界因素進(jìn)行計(jì)量和數(shù)據(jù)傳輸?shù)?，它具有傳光、傳感合一的特點(diǎn)，信息的獲取和傳輸都在光纖之中。23.由于光電開關(guān)輸出回路和輸入回路是電隔離的（即電絕緣），所以它可以在許多場合得到應(yīng)用。24.磁尺是檢測位移的基準(zhǔn)尺，磁頭用來讀取磁尺上的記錄信號(hào)。按讀取方式不同，磁頭分為動(dòng)態(tài)磁頭和LearnGeneralSecretaryon“twotolearna“strengt
