測它的正、反向電阻，電阻小時(shí)，萬用表黑表筆接的是控制極G，可以用剛才演示用的示教板電路。接通電源開關(guān)S，按一下按鈕開關(guān)SB，燈泡發(fā)光就是好的，不發(fā)光就是壞的。測量方法鑒別可控硅三個(gè)極的方法很簡單，根據(jù)P-N結(jié)的原理，只要用萬用表測量一下三個(gè)極之間的電阻值就可以。陽極與陰極之間的正向和反向電阻在幾百千歐以上，陽極和控制極之間的正向和反向電阻在幾百千歐以上（它們之間有兩個(gè)P-N結(jié)，而且方向相反，因此陽極和控制極正反向都不通）[1]?？刂茦O與陰極之間是一個(gè)P-N結(jié)，因此它的正向電阻大約在幾歐-幾百歐的范圍，反向電阻比正向電阻要大?？墒强刂茦O二極管特性是不太理想的，反向不是完全呈阻斷狀態(tài)的，可以有比較大的電流通過。

同時(shí)由于起動(dòng)轉(zhuǎn)矩較大，將對(duì)負(fù)載產(chǎn)生沖擊，增加傳動(dòng)部件的磨損和額外維護(hù)。所以當(dāng)電機(jī)的容量較大（一般為超過電源容量的20%—30%時(shí)）均采用降壓起動(dòng)。傳統(tǒng)上采用的降壓起動(dòng)的方法有Y/△換接起動(dòng)和自耦變壓器降壓起動(dòng)。雖然這兩種起動(dòng)方式均可降低起動(dòng)電流，但是在降壓起動(dòng)過程完成后的分檔投切和加全壓的瞬間，仍將產(chǎn)生數(shù)倍額定電流的尖峰電流（二次沖擊電流），此電流將對(duì)配電系統(tǒng)造成沖擊，同時(shí)產(chǎn)生的破壞性的動(dòng)態(tài)轉(zhuǎn)矩會(huì)引起水泵電機(jī)的機(jī)械震動(dòng)，對(duì)電機(jī)的轉(zhuǎn)子、中間齒輪等非常有害，并使供電線路電耗增大。軟啟動(dòng)器也是降壓起動(dòng)器的一種。它是利用性能先進(jìn)的微處理器，合理有序地控制大功率晶閘管組件導(dǎo)通，使之產(chǎn)生逐步增加的平滑的交流電壓加在交流電動(dòng)機(jī)上。

可以將傳感器固定在河底，用引壓管消除大氣壓力，從而直接測得水位。壓力式水位計(jì)有兩類。一類為氣泡型，在引壓管中不斷輸氣，用自動(dòng)調(diào)節(jié)的壓力天平將水壓力轉(zhuǎn)換成機(jī)械轉(zhuǎn)角量，從而帶動(dòng)記錄機(jī)構(gòu)。另一類為電測型，它應(yīng)用固態(tài)壓阻器件作傳感器，可直接將水壓力轉(zhuǎn)變成電壓模量或頻率量輸出,用導(dǎo)線傳輸至岸上進(jìn)行處理和記錄（圖2）。聲波式水位計(jì)是反射式水位計(jì)的一種，應(yīng)用聲波遇不同介面反射的原理來測定水位。分為氣介式和水介式兩類。氣介式以空氣為聲波的傳播介質(zhì)，換能器置于水面上方，由水面反射聲波，根據(jù)回波時(shí)間可計(jì)算并顯示出水位。儀器不接觸水體，完全擺脫水中泥沙，流速?zèng)_擊和水草等不利因素的影響。水介式是將換能器安裝在河底，向水面發(fā)射聲波。

雖然二值信號(hào)燈能夠?qū)崿F(xiàn)互斥鎖的功能，但兩者的關(guān)注內(nèi)容不同。信號(hào)燈強(qiáng)調(diào)共享資源，只要共享資源可用，其他進(jìn)程同樣可以修改信號(hào)燈的值；互斥鎖更強(qiáng)調(diào)進(jìn)程，占用資源的進(jìn)程使用完資源后，必須由進(jìn)程本身來解鎖。計(jì)數(shù)信號(hào)燈：信號(hào)燈的值可以取任意非負(fù)值（當(dāng)然受內(nèi)核本身的約束），用來統(tǒng)計(jì)資源，其值就代表可用資源的個(gè)數(shù)。技術(shù)要求1)交通信號(hào)燈系列產(chǎn)品及規(guī)格要求：熱鍍鋅框架式燈桿件符合國家標(biāo)準(zhǔn)。一體化信號(hào)燈，不允許采用包箍或支架連接，以保證美觀。2)道路交通信號(hào)燈必須符合GB14887-2003《道路交通信號(hào)燈技術(shù)要求及測試方法》的要求。具有部交通產(chǎn)品質(zhì)量監(jiān)督檢測中心的檢測報(bào)告,檢測報(bào)告必須是近2年內(nèi)送檢且在有效期內(nèi),無有效期或超過建議檢測期的視為無效檢測報(bào)告。
