style="text-indent:25px">化學發(fā)光法是利用某些化學反應所產(chǎn)生的發(fā)光現(xiàn)象對組分進行分析的方法，具有靈敏度高，選擇性好，使用簡單方法、快速等特點。因此，適用硫化物、氮氧化物、氨等標準氣體的分析。非色散紅外氣體分析器是利用不同的氣室和檢測器測量混合氣體中的一氧化碳、二氧化碳、二氧化硫、氨、甲烷、乙烷、丙烷、丁烷、乙炔等組分的含量。非色散紅外氣體分析器主要由紅外光源、試樣室、濾波器、斬波器、檢測器、放大器及數(shù)據(jù)顯示裝置組成。檢測器是儀器的交鍵部件，紅外檢測器分成熱檢測器和光子檢測器兩種類型。熱檢測器是一種能量轉(zhuǎn)換器，可以把熱能轉(zhuǎn)換成電信號，電信號經(jīng)放大后，輸入數(shù)據(jù)裝置。光子檢測器接受紅外輻射，將半導體中的電子從非導電能級激發(fā)到導電能級，在這一過程中半導體的電阻有所降低。所以半導體檢測器比熱檢測器響應快。</p><p style="text-indent:25px">氣體快速連接器工作原理：當壓縮空氣從A管咀進入氣體快速連接器時，氣體推動雙活塞向兩端(缸蓋端)直線運動，活塞上的齒條帶動旋轉(zhuǎn)軸上的齒輪逆時針方向轉(zhuǎn)動90度，閥門即被打開。此時氣動執(zhí)行閥兩端的氣體隨B管咀排出。反之，當壓縮空氣從B官咀進入氣體快速連接器的兩端時，氣體推動雙塞向中間直線運動，活塞上的齒條帶動旋轉(zhuǎn)軸上的齒輪順時針方向轉(zhuǎn)動90度，閥門即被關(guān)閉。此時氣體快速連接器中間的氣體隨A管咀排出。以上為標準型的傳動原理。根據(jù)用戶需求，氣體快速連接器可裝置成與標準型相反的傳動原***體快速連接器可以實現(xiàn)簡單、穩(wěn)定的控制速度。</p><div

style="text-indent:25px">在原子能工業(yè)上，氟有著重要的用途:人們用氟從鈾礦中提取鈾235，因為鈾和氟的化合物很易揮發(fā)，用分餾法可以把它和其它雜質(zhì)分開，得到十分純凈的鈾235。鈾235是制造原子單的原料。在鈾的所有化合物中，只有氟化物具有很好的揮發(fā)性能。氟重要的化合物是氟化氫。氟化氫很易溶解于水，水溶液叫氫氟酸，這正如氯化氫的水溶液叫氫氯酸(俗名叫鹽酸)一樣。氫氟酸都是裝在聚乙烯塑料瓶里的。如果裝在玻璃瓶里的話，過一會兒，整個玻璃瓶都會被它溶解掉--因為它能強烈地腐蝕玻璃(4HF+SiO2=SiF4+2H20)。人們便利用它的這一特性，先在玻璃上涂一層石蠟，再用刀子劃破蠟層刻成花紋，涂上氫氟酸。過了一會兒，洗去殘余的氫氟酸，刮掉蠟層，玻璃上便出現(xiàn)美麗的花紋。玻璃杯上的刻花、玻璃儀器上的刻度，都是用氫氟酸"刻"成的。由于氫氟酸會強烈腐蝕玻璃，所以在制造氫氟酸時不能使用玻璃的設備，而必須在鉛制設備中進行。人們用氟從鈾礦中提取鈾235，因為鈾和氟的化合物很易揮發(fā)。上海輕型軟管氣體元件品牌</p><p
